Introduction and Features

2-Banner-3.jpg

We are going to kick-off the New Year on a high-note by taking another look at Seasonic’s PRIME Titanium series power supplies. When we first tested the new PRIME 750W Titanium PSU last summer, we concluded it was the best overall PC power supply we had reviewed to date. So was that just a fluke? Did we get a hand-picked power supply? Or did our review sample truly represent the outstanding performance that a regular user would experience after buying one of the Seasonic PRIME Titanium series power supplies through normal retail channels? Today, we are going to test two more PRIME Titanium PSUs and compare our findings with the original PRIME 750W Titanium power supply test results. This will provide a unique opportunity to compare three different power supplies from the same series to see how consistent their performance really is, which can be a good indicator of quality.

Sea Sonic Electronics Co., Ltd has been designing and building PC power supplies since 1981 and they are one of the most highly respected manufacturers in the world. Not only do they market power supplies under their own Seasonic name but they are the OEM for numerous big name brands.

Seasonic’s new PRIME lineup was introduced earlier this year with the Titanium Series, which currently includes three models: 850W, 750W, and 650W (with more to follow). Additional PRIME models with both Platinum and Gold efficiency certifications are also making their way into retail channels with models ranging from 850W up to 1200W.

The two new power supplies we have in for review are the PRIME 650W and 850W Titanium models. These units also come with all modular cables and are certified to comply with the 80 Plus Titanium efficiency criteria; the highest available. The power supplies are designed to deliver extremely tight voltage regulation on the three primary rails (+3.3V, +5V and +12V) and they provide superior AC ripple and noise suppression with an extended hold-up time. Add in a super-quiet 135mm cooling fan with a Fluid Dynamic Bearing and a 10-year warranty, and you have the makings for an outstanding power supply.

Our Radeon RX 460 Build

This content was sponsored by AMD.

Be sure you check out part 2 of our story where we detail the performance our RX 460 build provides as well as our contest page where you can win this PC from AMD and PC Perspective!

Just before CES this month, AMD came to me asking about our views and opinions on its Radeon RX 460 line of graphics cards, how the GPU is perceived in the market, and how I felt they could better position it to the target audience. It was at that point that I had to openly admit to never actually having installed and used an RX 460 GPU before. I know, shame on me.

I like to pride myself and PC Perspective on being one of the top sources of technical information in the world of PCs, gaming or otherwise, and in particular on GPUs. But a pitfall that I fall into, and I imagine many other reviewers and media do as well, is that I overly emphasize the high end of the market. And that I tend to shift what is considered a “budget” product up the scale more than I should. Is a $250 graphics card really a budget product that the mass market is going to purchase? No, and the numbers clearly point to that as fact. More buyers purchase cards in the sub-$150 segment than in any other, upgrading OEMs PCs and building low cost boxes for themselves and for the family/friends.

So, AMD came to me with a proposal to address this deficiency in my mental database. If we were willing to build a PC based on the RX 460, testing it and evaluating it honestly, and then give that built system back to the community, they would pay for the hardware and promotion of such an event. So here we are.

To build out the RX 460-based PC, I went to the experts in the world of budget PC builds, the /r/buildapc subreddit. The community here is known for being the best at penny-pinching and maximizing the performance-per-dollar implementations on builds. While not the only types of hardware they debate and discuss in that group, it definitely is the most requested. I started a thread there to ask for input and advice on building a system with the only requirements being inclusion of the Radeon RX 460 and perhaps an AMD FreeSync monitor.

Check out prices of Radeon RX 460 graphics cards on Amazon!!

The results were impressive; a solid collection of readers and contributors gave me suggestions for complete builds based around the RX 460. Processors varied, memory configurations varied, storage options varied, but in the end I had at least a dozen solid options that ranged in price from $400-800. With the advice of the community at hand, I set out to pick the components for our own build, which are highlighted below:

Our Radeon RX 460 Build

  Budget Radeon RX 460 Build
Processor Intel Core i3-6100 - $109
Cooler CRYORIG M9i - $19
Motherboard ASUS H110M-A/M.2 - $54
Memory 2 x 4GB Crucial Ballistix DDR4-2400 - $51
Graphics Card XFX Radeon RX 460 2GB - $98
Storage 240GB Sandisk SSD Plus - $68
1TB Western Digital Blue - $49
Case Corsair Carbide Series 88R - $49
Power Supply EVGA 500 Watt - $42
Monitor Nixues VUE24A 1080p 144Hz FreeSync - $251
Total Price $549 on Amazon; $799 with monitor on Amazon

I’ll go in order of presentation for simplicity sake. First up is the selection of the Intel Core i3-6100 processor. This CPU was the most popular offering in the /r/buildapc group and has been the darling of budget gaming builds for a while. It is frequently used because of it $109 price tag, along with dual-core, HyperThreaded performance at 3.7 GHz; giving you plenty of headroom for single threaded applications. Since most games aren’t going to utilize more than four threads, the PC gaming performance will be excellent as well. One frequent suggestion in our thread was the Intel Pentium G4560, a Kaby Lake based part that will sell for ~$70. That would have been my choice but it’s not shipping yet, and I don’t know when it will be.

Introduction

Cooler Master's MasterLiquid Maker 92 is a unique liquid CPU cooler that fits all of its parts into one cluster atop the processor, and does it with a clever, hinged construction that allows it to be switched from an upright to a horizontal position at will. While the Maker 92 only occupies about as much space as a large tower air cooler in its upright position, the ability to fold it down provides both enhanced clearance and the option of directing airflow down to help cool motherboard components. But the big question for this cooler is just how effective can a closed-loop system be when it’s this compact? We’re about to find out!

Maker_92.jpg

Let's get part out if the way right off the bat: specialty small form-factor products generally don't offer competitive price/performance numbers, and critics are quick to point to this aspect of SFF computing. The small form-factor side of enthusiast PC building is a pretty small niche, and a product like the Maker 92 might not be for you; but what is important to consider when looking at a specialty product like this is the performance for its size, as designs of the most compact cooling components typically sacrifice something in this regard given their reduced surface area, smaller fan diameter, etc.

Most SFF solutions for processor cooling are of the air variety, with liquid being an option if a given enclosure supports your AiO (or custom loop) cooling of choice. Ultra low-profile CPU air coolers are popular for slim builds, and a product like the Maker 92 isn’t going to replace one of these if your enclosure of choice has a very low profile. Any system using a standard height PCI Express graphics card will work, though that top fan may have to come off depending on the case - which of course will affect cooling performance (in theory, anyway). But enough speculation! Let’s take a close look at this cooler and test out the fit and cooling prowess in both orientations.

AM4 Edging Closer to Retail

Many of us were thinking that one of the bigger stories around CES would be the unveiling of a goodly chunk of AM4 motherboards.  AM4 has been around for about half a year now, but only in system integrator builds (such as HP).  These have all been based around Bristol Ridge APU (essentially an updated Carrizo APU).  These SOCs are not exactly barn burners, but they provide a solid foundation for a low-cost build.  The APUs features 2 modules/4 cores, a GCN based GPU, and limited southbridge I/O functionality.

am4_01.jpg

During all this time the motherboards available from these OEMs are very basic units not fit for retail.  Users simply could not go out and buy a Bristol Ridge APU and motherboard for themselves off of Newegg, Amazon, and elsewhere.  Now after much speculation we finally got to see the first AM4 retail style boards unveiled at this year’s CES.  AMD showed off around 16 boards based on previously unseen B350 and X370 chipsets.

AMD has had a pretty limited number of chipsets that they have introduced over the years.  Their FM2+ offerings spanned the A series of chipsets, but they added very little in terms of functionality as compared to the 900 series that populate the AM3+ world.  The latest offering from AMD was the A88x which was released in September 2013.  At one time there was supposed to be a 1000 series of chipsets for AM3+, but those were cancelled and we have had the 900 series (which are identical to the previous 800 series) since 2011.  This has been a pretty stagnant area for AMD and their partners.  3rd party chips have helped shore up the feature divide between AMD and Intel’s regular release of new chipsets and technologies attached to them.

am4_02.jpg

There are three primary chipsets being released as well as two physical layer chips that allow the use of the onboard southbridge on Ryzen and Bristol Ridge.  The X370 for the enthusiast market, the B350 for the mainstream, and then the budget A320.  The two chipset options for utilizing the SOC’s southbridge functionality are the X300 and A/B300.

Before we jump into the chipsets we should take a look at what kind of functionality Ryzen and Bristol Ridge have that can be leveraged by motherboard manufacturers.  Bristol Ridge is a true SOC in that it contains the GPU, CPU, and southbridge functionality to stand alone.  Ryzen is different in that it does not have the GPU portion so it still requires a standalone graphics card to work.  Bristol Ridge is based off of the older Carrizo design and does not feature the flexibility in its I/O connections that Ryzen does.

am4_03.png

Bristol Ridge features up to 8 lanes of PCI-E 3.0.  The I/O on it includes 2 native SATA6G ports as well as the ability to either utilize two more PCI-e lanes or have them as x2 NVME.  That is about as flexible as it gets.  It also natively supports four USB 3.1 gen 1 ports.  For a chip that was designed to be a mobile focused SoC it makes sense that it will not max out PCI-E lanes or SATA ports.  It still is enough to satisfy most mobile and SFF builds.

High Bandwidth Cache

Apart from AMD’s other new architecture due out in 2017, its Zen CPU design, there is no other product that has had as much build up and excitement surrounding it than its Vega GPU architecture. After the world learned that Polaris would be a mainstream-only design that was released as the Radeon RX 480, the focus for enthusiasts came straight to Vega. It’s been on the public facing roadmaps for years and signifies the company’s return to the world of high end GPUs, something they have been missing since the release of the Fury X in mid-2015.

slides-2.jpg

Let’s be clear: today does not mark the release of the Vega GPU or products based on Vega. In reality, we don’t even know enough to make highly educated guesses about the performance without more details on the specific implementations. That being said, the information released by AMD today is interesting and shows that Vega will be much more than simply an increase in shader count over Polaris. It reminds me a lot of the build to the Fiji GPU release, when the information and speculation about how HBM would affect power consumption, form factor and performance flourished. What we can hope for, and what AMD’s goal needs to be, is a cleaner and more consistent product release than how the Fury X turned out.

The Design Goals

AMD began its discussion about Vega last month by talking about the changes in the world of GPUs and how the data sets and workloads have evolved over the last decade. No longer are GPUs only worried about games, but instead they must address profession workloads, enterprise workloads, scientific workloads. Even more interestingly, as we have discussed the gap in CPU performance vs CPU memory bandwidth and the growing gap between them, AMD posits that the gap between memory capacity and GPU performance is a significant hurdle and limiter to performance and expansion. Game installs, professional graphics sets, and compute data sets continue to skyrocket. Game installs now are regularly over 50GB but compute workloads can exceed petabytes. Even as we saw GPU memory capacities increase from Megabytes to Gigabytes, reaching as high as 12GB in high end consumer products, AMD thinks there should be more.

slides-8.jpg

Coming from a company that chose to release a high-end product limited to 4GB of memory in 2015, it’s a noteworthy statement.

slides-11.jpg

The High Bandwidth Cache

Bold enough to claim a direct nomenclature change, Vega 10 will feature a HBM2 based high bandwidth cache (HBC) along with a new memory hierarchy to call it into play. This HBC will be a collection of memory on the GPU package just like we saw on Fiji with the first HBM implementation and will be measured in gigabytes. Why the move to calling it a cache will be covered below. (But can’t we call get behind the removal of the term “frame buffer”?) Interestingly, this HBC doesn’t have to be HBM2 and in fact I was told that you could expect to see other memory systems on lower cost products going forward; cards that integrate this new memory topology with GDDR5X or some equivalent seem assured.

Semi-custom CPU

With the near comes a new push for performance, efficiency and feature leadership from Qualcomm and its Snapdragon line of mobile SoCs. The Snapdragon 835 was officially announced in November of last year when the partnership with Samsung on 10nm process technology was announced, but we now have the freedom to share more of the details on this new part and how it changes Qualcomm’s position in the ultra-device market. Though devices with the new 835 part won’t be on the market for several more months, with announcements likely coming at CES this year.

slides1-5.jpg

Qualcomm frames the story around the Snapdragon 835 processor with what they call the “five pillars” – five different aspects of mobile processor design that they have addressed with updates and technologies. Qualcomm lists them as battery life (efficiency), immersion (performance), connectivity, and security.

slides1-6.jpg

Starting where they start, on battery life and efficiency, the SD 835 has a unique focus that might surprise many. Rather than talking up the improvements in performance of the new processor cores, or the power of the new Adreno GPU, Qualcomm is firmly planted on looking at Snapdragon through the lens of battery life. Snapdragon 835 uses half of the power of Snapdragon 801.

slides2-2.jpg

The company touts usage claims of 1+ day of talk time, 5+ days of music playback, 11 hours of 4K video playback, 3 hours of 4K video capture and 2+ hours of sustained VR gaming. These sound impressive, but as we must always do in this market, you must wait for consumer devices from Qualcomm partners to really measure how well this platform will do. Going through a typical power user comparison of a device built on the Snapdragon 835 to one use the 820, Qualcomm thinks it could result in 2 or more hours of additional battery life at the end of the day.

We have already discussed the new Quick Charge 4 technology, that can offer 5 hours of use with just 5 minutes of charge time.

Architectural Background

It probably doesn't surprise any of our readers that there has been a tepid response to the leaks and reviews that have come out about the new Core i7-7700K CPU ahead of the scheduled launch of Kaby Lake-S from Intel. Replacing the Skylake-based 6700K part as the new "flagship" consumer enthusiast CPU, the 7700K has quite a bit stacked against it. We know that Kaby Lake is the first in the new sequence of tick-tock-optimize, and thus there are few architectural changes to any portion of the chip. However, that does not mean that the 7700K and Kaby Lake in general don't offer new capabilities (HEVC) or performance (clock speed). 

The Core i7-7700K is in an interesting spot as well with regard to motherboards and platforms. Nearly all motherboards that run the Z170 chipset will be able to run the new Kaby Lake parts without requiring an upgrade to the newly released Z270 chipset. However, the likelihood that any user on a Z170 platform today using a Skylake processor will feel the NEED to upgrade to Kaby Lake is minimal, to say the least. The Z270 chipset only offers a couple of new features compared to last generation, so the upgrade path is again somewhat limited in excitement.

Let's start by taking a look at the Core i7-7700K and how it compares to the previous top-end parts from the consumer processor line and then touch on the changes that Kaby Lake brings to the table.

slides06.jpg

With the beginning of CES just days away (as I write this), Intel is taking the wrapping paper off of its first gift of 2017 to the industry. As you can see from the slide above, more than just the Kaby Lake-S consumer socketed processors are launching today, but other components including Iris Plus graphics implementations and quad-core notebook implementations will need to wait for another day.

slides10.jpg

For DIY builders and OEMs, Kaby Lake-S, now known as the 7th Generation Core Processor family, offer some changes and additions. First, we will get a dual-core HyperThreaded processor with an unlocked designation in the Core i3-7350K. Other than the aforementioned Z270 chipset, Kaby Lake will be the first platform compatible with Intel Optane memory. (To be extra clear, I was told that previous processors will NOT be able to utilize Optane in its M.2 form factor.)

slides11.jpg

Though we have already witnessed Lenovo announcing products using Optane, this is the first official Intel discussion about it. Optane memory will be available in M.2 modules that can be installed on Z270 motherboards, improving snappiness and responsiveness. It seems this will be launched later in the quarter as we don't have any performance numbers or benchmarks to point to demonstrating the advantages that Intel touts. I know both Allyn and I are very excited to see how this differs from previous Intel caching technologies.

Introduction, Specifications and Packaging

Introduction

Earlier this year we covered the lower two capacities of the Samsung 750 EVO. We had some requests for a review of the 500GB model as soon as it was added to their lineup, and Samsung promptly sent a sample, but I delayed that review in the interest of getting the full 750 EVO lineup tested under our new storage test suite. I've been running batches of SSDs through this new suite, and we now have enough data points to begin cranking out some reviews. The 750 EVO was at the head of the line, so we will be starting with it first. I'm 'reissuing' our review as a full capacity roundup of the 750 EVO lineup as these are fresh results on a completely new test suite.

Specifications

These are the 'Rev. 2' specifications from Samsung, which include the 500GB model of the 750 EVO. The changes are not significant, mainly a slight bump to random performance of the top capacity model along with a changeover to lower power DDR3 (of twice the capacity) for the 500GB model's system cache.

Vulkan 1.0, OpenGL 4.5, and OpenGL ES 3.2 on a console

A few days ago, sharp eyes across the internet noticed that Nintendo’s Switch console has been added to lists of compliant hardware at The Khronos Group. Vulkan 1.0 was the eye-catcher, although the other tabs also claims conformance with OpenGL 4.5 and OpenGL ES 3.2. The device is not listed as compatible with OpenCL, although that does not really surprise me for a single-GPU gaming system. The other three APIs have compute shaders designed around the needs of game developers. So the Nintendo Switch conforms to the latest standards of the three most important graphics APIs that a gaming device should use -- awesome.

But what about performance?

In other news, Eurogamer / Digital Foundary and VentureBeat uncovered information about the hardware. It will apparently use a Tegra X1, which is based around second-generation Maxwell, that is under-clocked from what we see on the Shield TV. When docked, the GPU will be able to reach 768 MHz on its 256 CUDA cores. When undocked, this will drop to 307.2 MHz (although the system can utilize this mode while docked, too). This puts the performance at ~315 GFLOPs when in mobile, pushing up to ~785 GFLOPs when docked.

You might compare this to the Xbox One, which runs at ~1310 GFLOPs, and the PlayStation 4, which runs at ~1840 GFLOPs. This puts the Nintendo Switch somewhat behind it, although the difference is even greater than that. The FLOP calculation of Sony and Microsoft is 2 x Shader Count x Frequency, but the calculation of Nintendo’s Switch is 4 x Shader Count x Frequency. FMA is the factor of two, but the extra factor of two in Nintendo’s case... ...

Yup, the Switch’s performance rating is calculated as FP16, not FP32.

Snippet from an alleged leak of what Nintendo is telling developers.
If true, it's very interesting that FP16 values are being discussed as canonical.

Reducing shader precision down to 16-bit is common for mobile devices. It takes less transistors to store and translate half-precision values, and accumulated error will be muted by the fact that you’re viewing it on a mobile screen. The Switch isn’t always a mobile device, though, so it will be interesting to see how this reduction of lighting and shading precision will affect games on your home TV, especially in titles that don’t follow Nintendo’s art styles. That said, shaders could use 32-bit values, but then you are cutting your performance for those instructions in half, when you are already somewhat behind your competitors.

As for the loss of performance when undocked, it shouldn’t be too much of an issue if Nintendo pressures developers to hit 1080p when docked. If that’s the case, the lower resolution, 720p mobile screen will roughly scale with the difference in clock.

Lastly, there is a bunch of questions surrounding Nintendo’s choice of operating system: basically, all the questions. It’s being developed by Nintendo, but we have no idea what they forked it from. NVIDIA supports the Tegra SoC on both Android and Linux, it would be legal for Nintendo to fork either one, and Nintendo could have just asked for drivers even if NVIDIA didn’t already support the platform in question. Basically, anything is possible from the outside, and I haven’t seen any solid leaks from the inside.

The Nintendo Switch launches in March.

Processors

Intel Core i7-6700K Quad-Core Unlocked Processor - $344, Amazon

Intel Core i7-6700K.jpg

It's a bit of an interesting time for CPUs with Intel's Kaby Lake (e.g. 7700K) not out yet and AMD's Ryzen Zen-based (e.g. 8 core Summit Ridge) processors slated for release early next year. Last year the i7-6700K was  our top pick, and due to timing of upcoming releases, it is still the pick for this year though it may be wise to look at other gift ideas this year unless they really want that gaming PC ASAP. On the plus side, it is a bit cheaper than last year! You can read our review of the Core i7 6700K here.

AMD Athlon X4 880K Unlocked Quad Core - $92, Amazon

On the AMD side of things, the Athlon X4 880K is a great processor to base a budget gaming build around. The pricing works out a bit cheaper than the old 860K as well as offering slightly faster clockspeeds and a better stock cooler.

Continue reading our holiday gift guide for our picks for graphics cards, storage, and more!

Graphics Cards

NVIDIA GTX 1080 (EVGA FTW Hybrid) - $730, EVGA (Amazon has non FTW Hybrid for $700)

EVGA GTX 1080 FTW Hybrid.jpg

The NVIDIA GTX 1080 is the current consumer-grade performance king, and there are a number of brands to choose from. Whichever you go with, the Pascal-based graphics card is ready for 1440 and even 4k gaming along with VR (virtual reality) gaming. The EVGA FTW Hybrid is a beast of a card that can easily be overclocked with keeping temperatures in check.

If you are looking for something a bit cheaper, AMD's RX 480 is a great midrange graphics card that can easily do 1080p with the details cranked up. Sapphire has a good factory overclocked card with the RX 480 Nitro+ which can be found for $250. For reference, check out our reviews on the RX 480 (we also have a video of the Sapphire card specifically) and it's competitor the GTX 1060.

Storage

Samsung 960 Evo 1TB NVMe M.2 SSD - $480, Amazon

Samsung 960 Evo 1TB NVMe M2 SSD.jpg

Samsung's recently released 960 Evo is not the fastest SSD available, but it's no slouch either. Using Samsung's TLC V-NAND flash, its Polaris controller, and 1GB of DDR3 cache, the drive packs 1TB of speedy storage into the M.2 form factor. The NVMe SSD is rated at 3,200 MB/s sequential reads, 1,900 MB/s sequential writes, 380,000 4k random reads and 360,000 4k random writes (IOPS ratings at QD32). It is rated at 1.5 million hours MTBF and while it does not have the lifetime or write speeds of the pro version (960 Pro), it is quite a bit cheaper! The gamer in your life will appreciate the super fast loading times too!

If you are looking for something a bit more down to earth, SATA SSDs continue to get cheaper and more capacious and there are even some good budget M.2 options these days!

MyDigitalSSD BPX 480GB NVMe M.2 SSD - $200, Amazon

MyDigitalSSD BPX 480GB NVMe M2 SSD.jpg

MyDigitalSSD's BPX solid state drive pairs a Phison PS5007-E7 controller with up to 480GB of 2D MLC NAND. The drive is rated at a respectable 2,600 MB/s sequential reads, 1,300 MB/s sequential writes, and approximately 208,728 4k random read IOPS and 202,713 4k random write IOPS. Despite being from a less well known company, the budget drive puts up very nice numbers for the price and comes with a 5 year warranty, 2 million hours MTBF rating, and 1,400 TB total bytes written rating on the flash. Pricing is much more budget friendly at $200 for the 480GB model, $115 for the 240GB, and $70 for the 120GB drive.

SATA SSD Recommendations

SATA SSDs are still great options for a system build and/or HDD upgrade, and Allyn has a few picks later on in this guide.

The following pages are individual selections / gift ideas from each staff member!

Premium Minimalism

Das Keyboard describes their products as "the ultimate experience for badasses", and the Austin, TX based company has delivered premium designs since their initial (completely blank) keyboard in 2005. The Prime 13 is a traditional 104-key design (with labeled keys), and features Cherry MX Brown switches and simple white LED backlighting. So it is a truly "badass" product? Read on to find out!

DSC_0635.jpg

"Das Keyboard Prime 13 is a minimalist mechanical keyboard designed to take productivity to the next level. Free of fancy features, the Prime 13 delivers an awesome typing experience by focusing on premium material and simple design. Featuring an anodized aluminum top panel, Cherry MX switches with white LEDs, USB pass-through and an extra-long braided cable, the Prime 13 is the ideal mechanical keyboard for overachievers who want get the job done."

I don't need to tell prospective mechanical keyboard buyers that the market is very crowded, and it seems to grow every month. Just about PC accessory maker offers at least one option, and many have tried to distinguish themselves with RGB lighting effects and software with game-specific profiles and the like. So is there still room for a simple, non-RGB keyboard with no special software involved? I think so, but it will need to be quite a premium design to justify a $149 price tag, and that's what the Prime 13 will run at retail. First impressions are very good, but I'll try to cover the experience as well as I can in text and photos in this review.

Ryzen coming in 2017

As much as we might want it to be, today is not the day that AMD launches its new Zen processors to the world. We’ve been teased with it for years now, with trickles of information at event after event…but we are going to have to wait a little bit longer with one more tease at least. Today’s AMD is announcing the official branding of the consumer processors based on Zen, previously code named Summit Ridge, along with a clock speed data point and a preview of five technology that will help it be competitive with the Intel Core lineup.

ryzen-22.jpg

The future consumer desktop processor from AMD will now officially be known as Ryzen. That’s pronounced “RISE-IN” not “RIS-IN”, just so we are all on the same page. CEO Lisa Su was on stage during the reveal at a media event last week and claimed that while media, fans and AMD fell in love with the Zen name, it needed a differentiation from the architecture itself. The name is solid – not earth shattering though I foresee a long life of mispronunciation ahead of it.

Now that we have the official branding behind us, let’s get to the rest of the disclosed information we can reveal today.

ryzen-24.jpg

We already knew that Summit Ridge would ship with an 8 core, 16 thread version (with lower core counts at lower prices very likely) but now we know a frequency and a cache size. AMD tells us that there will be a processor (the flagship) that will have a base clock of 3.4 GHz with boost clocks above that. How much above that is still a mystery – AMD is likely still tweaking its implementation of boost to get as much performance as possible for launch. This should help put those clock speed rumors to rest for now.

The 20MB of cache matches the Core i7-6900K, though obviously with some dramatic architecture differences between Broadwell and Zen, the effect and utilization of that cache will be interesting measure next year.

ryzen-10.jpg

We already knew that Ryzen will be utilizing the AM4 platform, but it’s nice to see it reiterated a modern feature set and expandability. DDR4 memory, PCI Express Gen3, native USB 3.1 and NVMe support – there are all necessary building blocks for a modern consumer and enthusiast PC. We still should see how many of these ports the chipset offers and how aggressive motherboard companies like ASUS, MSI and Gigabyte are in their designs. I am hoping there are as many options as would see for an X99/Z170 platform, including budget boards in the $100 space as well as “anything and everything” options for those types of buyers that want to adopt AMD’s new CPU.

AMD Enters Machine Learning Game with Radeon Instinct Products

NVIDIA has been diving in to the world of machine learning for quite a while, positioning themselves and their GPUs at the forefront on artificial intelligence and neural net development. Though the strategies are still filling out, I have seen products like the DIGITS DevBox place a stake in the ground of neural net training and platforms like Drive PX to perform inference tasks on those neural nets in self-driving cars. Until today AMD has remained mostly quiet on its plans to enter and address this growing and complex market, instead depending on the compute prowess of its latest Polaris and Fiji GPUs to make a general statement on their own.

instinct-18.jpg

The new Radeon Instinct brand of accelerators based on current and upcoming GPU architectures will combine with an open-source approach to software and present researchers and implementers with another option for machine learning tasks.

The statistics and requirements that come along with the machine learning evolution in the compute space are mind boggling. More than 2.5 quintillion bytes of data are generated daily and stored on phones, PCs and servers, both on-site and through a cloud infrastructure. That includes 500 million tweets, 4 million hours of YouTube video, 6 billion google searches and 205 billion emails.

instinct-6.jpg

Machine intelligence is going to allow software developers to address some of the most important areas of computing for the next decade. Automated cars depend on deep learning to train, medical fields can utilize this compute capability to more accurately and expeditiously diagnose and find cures to cancer, security systems can use neural nets to locate potential and current risk areas before they affect consumers; there are more uses for this kind of network and capability than we can imagine.

Third annual release

For the past two years, AMD has made a point of releasing one major software update to Radeon users and gamers annually. In 2014 this started with Catalyst Omega, a dramatic jump in performance, compatibility testing and new features were the story. We were told that for the first time in a very long while, and admitting this was the most important aspect to me, AMD was going to focus on building great software with regular and repeated updates. In 2015 we got a rebrand along with the release: Radeon Software Crimson Edition.  AMD totally revamped the visual and user experience of the driver software, bringing into the modern world of style and function. New features and added performance were also the hallmarks of this release, with a stronger promise to produce more frequent drivers to address any performance gaps, stability concerns and to include new features.

For December 2016 and into the new year, AMD is launching the Radeon Software Crimson ReLive Edition driver. While the name might seem silly, it will make sense as we dive into the new features.

While you may have seen the slides leak out through some other sites over the past 48 hours, I thought it was worth offering my input on the release.

Not a performance focused story

The first thing that should be noted with the ReLive Edition is that AMD isn’t making any claims of substantially improved performance. Instead, the Radeon Technologies Group software team is dedicated to continued and frequent iterations that improve performance gradually over time.

slides40.jpg

As you can see in the slide above, AMD is showing modest 4-8% performance gains on the Radeon RX 480 with the Crimson ReLive driver, and even then, its being compared to the launch driver of 16.6.2.  That is significantly lower than the claims made in previous major driver releases. Talking with AMD about this concern, it told us that they don’t foresee any dramatic, single large step increases in performance going forward. The major design changes that were delivered over the last several years, starting with a reconstruction of the CrossFire system thanks to our testing, have been settled. All we should expect going forward is a steady trickle of moderate improvements.

(Obviously, an exception may occur here or there, like with a new game release.)

Radeon ReLive Capture and Streaming Feature

So, what is new? The namesake feature for this driver is the Radeon ReLive application that is built in. ReLive is a capture and streaming tool that will draw obvious comparisons to what NVIDIA has done with GeForce Experience. The ReLive integration is clean and efficient, well designed and seems easy to use in my quick time with it. There are several key capabilities it offers.

First, you can record your gameplay with the press of a hotkey; this includes the ability to record and capture the desktop as well. AMD has included a bevy of settings for your captures to adjust quality, resolution, bitrate, FPS and more.

rev10-table.jpg

ReLive supports resolutions up to 4K30 with the Radeon R9 series of GPUs and up to 1440p30 with the RX 480/470/460. That includes both AVC H.264 and HEVC H.265.

Along with recording is support for background capture, called Instant Replay. This allows the gamer to always record in the background, up to 20 minutes, so you can be sure you capture amazing moments that happen during your latest gaming session. Hitting a hotkey will save the clip permanently to the system.
