Tagged: Zen, Ryzen 1800X, ryzen, overclocking, LN2, Cinebench, amd
During AMD’s Ryzen launch event a team of professional overclockers took the stage to see just how far they could push the top Zen-based processor. Using a bit of LN2 (liquid nitrogen) and a lot of voltage, the overclocking team was able to hit an impressive 5.20 GHz with all eight cores (16 threads) enabled!
In addition to the exotic LN2 cooling, the Ryzen 7 1800X needed 1.875 volts to hit 5.20 GHz. That 5.20 GHz was achieved by setting the base clock at 137.78 MHz and the multiplier at 37.75. Using these settings, the chip was even stable enough to benchmark with a score of 2,363 on Cinebench R15’s multi-threaded test.
According to information from AMD, a stock Ryzen 7 1800X comes clocked at 3.6 GHz base and up to 4 GHz boost (XFR can go higher depending on HSF) and is able to score 1,619 in Cinebench. The 30% overclock to 5.20 GHz got the overclockers an approximately 45% higher CInebench score.
Further, later in the overclocking event, they managed to break a Cinebench world record of 2,445 points by achieving a score of 2,449 (it is not clear what clockspeed this was at). Not bad for a brand-new processor!
The overclocking results are certainly impressive, and suggest that Ryzen may be a decent overclocker so long as you have the cooling setup to get it there (the amount of voltage needed is a bit worrying though heh). Interestingly, HWBot shows a Core i7 6900K (also 8C/16T) hitting 5.22 GHz and scoring 2,146 in CInebench R15. That Ryzen can hit similar numbers with all cores and threads turned on is promising.
I am looking forward to seeing what people are able to hit on air and water cooling and if XFR will work as intended and get most of the way to a manual overclock without the effort of manually overclocking. I am also curious how the power phases and overclocking performance will stack up on motherboards using the B350 versus X370 chipsets. With the eight core chips able to hit 5.2, I expect the upcoming six core Ryzen 5 and four core Ryzen 3 processors to clock even higher which would certainly help gaming performance for budget builds!
Austin Evans was able to get video of the overclocking event which you can watch here (Vimeo).

Today at the AMD Capsaicin & Cream event at GDC 2017, Senior VP of the Radeon Technologies Group, Raja Koduri officially revealed the branding that AMD will use for their next generation GPU products.
While we usually see final product branding deviate from their architectural code names (e.g. Polaris becoming the Radeon RX 460, 470 and 480), AMD this time has decided to embrace the code name for the retail naming scheme for upcoming graphics cards featuring the new GPU – Radeon RX Vega.
However, we didn't just get a name for Vega-based GPUs. Raja also went into some further detail and showed some examples of technologies found in Vega.
First off is the High-Bandwidth Cache Controller found in Vega products. We covered this technology during our Vega architecture preview last month at CES, but today we finally saw a demo of this technology in action.
Essentially, the High-Bandwidth Cache Controller (HBCC) allows Vega GPUs to address all available memory in the system (including things like NVMe SSDs, system DRAM and network storage.) AMD claims that by using the already fast memory you have available on your PC to augment onboard GPU memory (such as HBM2) they will be able to offer less expensive graphics cards that ultimately offer access to much more memory than current graphics cards.
The demo that they showed on stage featured Deus Ex: Mankind Divided running on a system with a Vega GPU running with 2GB of VRAM, and Ryzen CPU. By turning HBCC on, they were able to show a 50% increase in average FPS, and a 100% increase in minimum FPS.
While we probably won't actually see a Vega product with such a small VRAM implementation, it was impressive to see how HBCC was able to dramatically improve the playability of a 2GB GPU on a game that has no special optimizations to take advantage of the High-Bandwidth Cache.
The other impressive demo running on Vega at the Capsaicin & Cream event centered around what AMD is calling Rapid Pack Math.
Rapid Pack Math is an implementation of something we have been hearing and theorizing a lot about lately, the use of FP16 shaders for some graphic effects in games. By using half-precision FP16 shaders instead of the current standard FP32 shaders, developers are able to get more performance out of the same GPU cores. In specific, Rapid Pack Math allows developers to run half-precision FP16 shaders at exactly 2X the speed of traditional standard-precision FP32 shaders.
While the lower precision of FP16 shaders won't be appropriate for all GPU effects, AMD was showing a comparison of their TressFX hair rendering technology running on both standard and half-precision shaders. As you might expect, AMD was able to render twice the amount of hair strands per second, making for a much more fluid experience.
Just like we saw with the lead up to the Polaris GPU launch, AMD seems to be releasing a steady stream of information on Vega. Now that we have the official branding for Vega, we eagerly await getting our hands on these new High-end GPUs from AMD.

What an interesting time it will be with Intel slinging Z270's at the same time AMD's Z370 arrives on the scene; there is no possible way some people could get confused. It will also make the next generation of board names interesting as the two companies fight for numbering rights. GIGABYTE's Aorus Z270X Gaming 9 comes with an impressive price tag of $500, so it will be interesting to see if [H]ard|OCP finds the feature set on the board worth of that investment. The four 16x PCIe 3.0 slots will support four GPUs simultaneously and there are both a pair of M.2 and U.2 slots, to say nothing of the onboard SoundBlaster. Head on over to read through the full review.
"GIGABYTE’s Z270X Gaming 9 is one of the most feature rich and ultra-high end offerings you’ll see for the Z270 chipset this year. We were super fond of last year’s similar offering and as a result, the Z270X Gaming 9 has very large shoes to fill. With its massive feature set and overclocking prowess, it is poised to be one of the best motherboards of the year."

Tagged: microsoft, oops, Lawsuit
If you purchased anything from the Microsoft store between November 2013 and February 24 of this year and live in the USA you could be eligible for up to $100 in cash damages. It seems that the credit card information they provided on receipts contained more than half of your credit card numbers which is in violation of a law implemented in 2003 which states that no more than five numbers can be shown on receipts. Now that the judgment against Microsoft is in, the proposed settlement for Microsoft to set aside $1,194,696US for customers who were affected by this issue. The settlement needs to be approved by the judge so you cannot claim your money immediately, keep an eye out for more new. The Register have posted links to the original lawsuit as well as the judgment right here.
"On Friday, the Redmond giant agreed to give up roughly seven minutes of its quarterly revenue to a gaggle of Microsoft Store customers who claimed that their receipts displayed more of their payment card numbers than legally allowed."

You may recall a while back Allyn put together an article detailing the new types of SD cards hitting the market which will support 4K recording in cameras. Modders Inc just wrapped up a review of one of these cards, Patriot's 256GB LX Series SDXC card with an included adapter for those who need it. The price certainly implies it is new technology, $200 for 256GB of storage is enough to make anyone pause, so the question becomes why one would pay such a premium. Their benchmarks offer insight into this, with 83Mb/s write and 96Mb/s read in both ATTO and CrystalDisk proving that this is a far cry from the performance of older SD cards and worthy of that brand new ultra high definition camera you just picked up. Lets us hope the prices plummet as they did with the previous generations of cards.
"Much like Mary Poppins bag of wonders, Patriot too has a method of fitting a substantial amount of goodness in a small space with the release of their 256GB LX Series SDXC class 10 memory card. Featuring an impressive 256GB of storage and boasting this as an “ultra high speed” card for QHD video production and high resolution photos."

Tagged: MWC, GDC, VRMark, Servermark, OptoFidelity, cyan room, benchmark
Futuremark are showing off new benchmarks at GDC and MWC, the two conferences which are both happening this week. We will have quite a bit of coverage this week as we try to keep up with simultaneous news releases and presentations.
First up is a new benchmark in their recently released DX12 VRMark suite, the new Cyan Room which sits between the existing two in the suite. The Orange Room is to test if your system is capable of providing you with an acceptable VR experience or if your system falls somewhat short of the minimum requirements while the Blue Room is to show off what a system that exceeds the recommended specs can manage. The Cyan room will be for those who know that their system can handle most VR, and need to test their systems settings. If you don't have the test suite Humble Bundle has a great deal on this suite and several other tools, if you act quickly.
Next up is a new suite to test Google Daydream, Google Cardboard, and Samsung Gear VR performance and ability. There is more than just performance to test when you are using your phone to view VR content, such as avoiding setting your eyeholes on fire. The tests will help you determine just how long your device can run VR content before overheating becomes an issue and interferes with performance, as well as helping you determine your battery life.
VR Latency testing is the next in the list of announcements and is very important when it comes to VR as high or unstable latency is the reason some users need to add a bucket to their list of VR essentials. Futuremark have partnered with OptoFidelity to produce VR Multimeter HMD hardware based testing. This allows you, and hopefully soon PCPer as well, to test motion-to-photon latency, display persistence, and frame jitter as well as audio to video synchronization and motion-to-audio-latency all of which could lead to a bad time.
Last up is the brand new Servermark to test the performance you can expect out of virtual servers, media servers and other common tasks. The VDI test lets you determine if a virtual machine has been provisioned at a level commensurate to the assigned task, so you can adjust it as required. The Media Transcode portion lets you determine the maximum number of concurrent streams as well as the maximum quality of those streams which your server can handle, very nice for those hosting media for an audience.
Expect to hear more as we see the new benchmarks in action.

Tagged: M2, Arduino Due, macchina, Kickstarter, open source, DIY
There is a Kickstarter out there for all you car enthusiasts and owners, the Arduino Duo based Macchina M2 which allows you to diagnose and change how your car functions. They originally developed the device during a personal project to modify a Ford Contour into an electric car, which required serious reprogramming of sensors and other hardware in the car. They realized that their prototype could be enhanced to allow users to connect into the hardware of their own cars to monitor performance, diagnose issues or even modify the performance. Slashdot has the links and their trademarked reasonable discourse for those interested, if you have the hardware already you can get the M2 interface $45, $79 or more for the hardware and accessories.
"Challenging "the closed, unpublished nature of modern-day car computers," their M2 device ships with protocols and libraries "to work with any car that isn't older than Google." With catchy slogans like "root your ride" and "the future is open," they're hoping to build a car-hacking developer community, and they're already touting the involvement of Craig Smith, the author of the Car Hacker's Handbook from No Starch Press."

Qualcomm has announced their first successful 5G New Radio (NR) connection using their prototype sub-6 GHz prototype system. This announcement was followed by today's news of Qualcomm's collaboration with Ericsson and Vodafone to trial 5G NR in the second half of 2017, as we approach the realization of 5G. New Radio is expected to become the standard for 5G going forward as 3GPP moves to finalize standards with release 15.
"5G NR will make the best use of a wide range of spectrum bands, and utilizing spectrum bands below 6 GHz is critical for achieving ubiquitous coverage and capacity to address the large number of envisioned 5G use cases. Qualcomm Technologies’ sub-6 GHz 5G NR prototype, which was announced and first showcased in June 2016, consists of both base stations and user equipment (UE) and serves as a testbed for verifying 5G NR capabilities in bands below 6 GHz."
The Qualcomm Sub-6 GHz 5G NR prototype (Image credit: Qualcomm)
Qualcomm first showed their sub-6 Ghz prototype this past summer, and it will be on display this week at MWC. The company states that the system is designed to demonstrate how 5G NR "can be utilized to efficiently achieve multi-gigabit-per-second data rates at significantly lower latency than today’s 4G LTE networks". New Radio, or NR, is a complex topic as it related to a new OFDM-based wireless standard. OFDM refers to "a digital multi-carrier modulation method" in which "a large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels". With 3GPP adopting this standard going forward the "NR" name could stick, just as "LTE" (Long Term Evolution) caught on to describe the 4G wireless standard.
Along with this 5G NR news comes the annoucement of the expansion of its X50 modem family, first announced in October, "to include 5G New Radio (NR) multi-mode chipset solutions compliant with the 3GPP-based 5G NR global system", according to Qualcomm. This 'multi-mode' solution provides full 4G/5G compatibility with "2G/3G/4G/5G functionality in a single chip", with the first commercial devices expected in 2019.
"The new members of the Snapdragon X50 5G modem family are designed to support multi-mode 2G/3G/4G/5G functionality in a single chip, providing simultaneous connectivity across both 4G and 5G networks for robust mobility performance. The single chip solution also supports integrated Gigabit LTE capability, which has been pioneered by Qualcomm Technologies, and is an essential pillar for the 5G mobile experience as the high-speed coverage layer that co-exists and interworks with nascent 5G networks. This set of advanced multimode capabilities is designed to provide seamless Gigabit connectivity – a key requirement for next generation, premium smartphones and mobile computing devices."
Full press releases after the break.

Tagged: zenimax, Oculus
As far as I know, it’s fairly common to seek injunctions during legal fights over intellectual rights cases, so I’m not sure how surprising this should be. Still, after the $500 million USD judgment against Oculus, ZeniMax has indeed filed for a court order to, according to UploadVR, block the usage of Oculus PC software, Oculus Mobile software, and the plug-ins for Unity and Unreal Engine. They also demand, as usual, that Oculus deletes all copies of the infringing code and a few other stipulations.
I should stress that this is just a filing. It would need to be accepted for it to have any weight.
The timing is quite disruptive to Oculus, too, even if by total co-incidence. Epic Games is about to release their flagship, Oculus-exclusive title, Robo Recall, which was intended to be released for free to those who have Oculus Touch controllers. If it succeeds, and that’s way more if than when at this point, then that could sting for whoever gets stuck with the game’s invoice, which (I assume) would be Oculus.
Personally, I’m not quite sure how far this will go. Based on my memory of the jury decision, ZeniMax is entitled to $500 million USD for prior damages, and nothing for ongoing damages. You would think that, if a jury ruled that the infringement has no lasting effect, that an injunction wouldn’t recover any of that non-existent value. On the other hand, I’m not a judge (or anyone else of legal relevance) so what I reason doesn’t really matter outside the confines of this website.
We’ll need to wait and see if this goes anywhere.

Tagged: x370, sli, ryzen, PCI-E 3.0, gaming, crossfire, b350, amd
Computerbase.de recently published an update (translated) to an article outlining the differences between AMD’s AM4 motherboard chipsets. As it stands, the X370 and B350 chipsets are set to be the most popular chipsets for desktop PCs (with X300 catering to the small form factor crowd) especially among enthusiasts. One key differentiator between the two chipsets was initially support for multi-GPU configurations with X370. Now that motherboards have been revealed and are up for pre-order now, it turns out that the multi-GPU lines have been blurred a bit. As it stands, both B350 and X370 will support AMD’s CrossFire multi-GPU technology and the X370 alone will also have support for NVIDIA’s SLI technology.
The AM4 motherboards equipped with the B350 and X370 chipsets that feature two PCI-E x16 expansion slots will run as x8 in each slot in a dual GPU setup. (In a single GPU setup, the top slot can run at full x16 speeds.) Which is to say that the slots behave the same across both chipsets. Where the chipsets differ is in support for specific GPU technologies where NVIDIA’s SLI is locked to X370. TechPowerUp speculates that the decision to lock SLI to its top-end chipset is due, at least in part, to licensing costs. This is not a bad thing as B350 was originally not going to support any dual x16 slot multi-GPU configurations, but now motherboard manufacturers are being allowed to enable it by including a second slot and AMD will reportedly permit CrossFire usage (which costs AMD nothing in licensing). Meanwhile the most expensive X370 chipset will support SLI for those serious gamers that demand and can afford it. Had B350 supported SLI and carried the SLI branding, they likely would have been ever so slightly more expensive than they are now. Of course, DirectX 12's multi-adapter will work on either chipset so long as the game supports it.
|X370||B350||A320||X300 / B300 / A300||Ryzen CPU||Bristol Ridge APU|
|PCI-E 3.0||0||0||0||4||20 (18 w/ 2 SATA)||10|
|USB 3.1 Gen 2||2||2||1||1||0||0|
|USB 3.1 Gen 1||6||2||2||2||4||4|
|SATA 6 Gbps||4||2||2||2||2||2|
|Overclocking Capable?||Yes||Yes||No||Yes (X300 only)|
Multi-GPU is not the only differentiator though. Moving up from B350 to X370 will get you 6 USB 3.1 Gen 1 (USB 3.0) ports versus 2 on B350/A30/X300, two more PCI-E 2.0 lanes (8 versus 6), and two more SATA ports (6 total usable; 4 versus 2 coming from the chipset).
Note that X370, B350, and X300 all support CPU overclocking. Hopefully this helps you when trying to decide which AM4 motherboard to pair with your Ryzen CPU once the independent benchmarks are out. In short, if you must have SLI you are stuck ponying up for X370, but if you plan to only ever run a single GPU or tend to stick with AMD GPUs and CrossFire, B350 gets you most of the way to a X370 for a lot less money! You do not even have to give up any USB 3.1 Gen 2 ports though you limit your SATA drive options (it’s all about M.2 these days anyway heh).
For those curious, looking around on Newegg I notice that most of the B350 motherboards have that second PCI-E 3.0 x16 slot and CrossFire support listed in their specifications and seem to average around $99. Meanwhile X370 starts at $140 and rockets up from there (up to $299!) depending on how much bling you are looking for!
Are you going for a motherboard with the B350 or X370 chipset? Will you be rocking multiple graphics cards?

When VR started to take off, developers begun to realize that audio is worth some attention. Historically, it’s been difficult to market, but that’s par for the course when it comes to VR technology, so I guess that’s no excuse to pass it up anymore. Now Valve, the owners of the leading VR platform on the PC have just released an API for audio processing: Steam Audio SDK.
Image Credit: Valve Software
First, I should mention that the SDK is not quite open. The GitHub page (and the source code ZIP in its releases tab) just contain the license (which is an EULA) and the readme. That said, Valve is under no obligation to provide these sorts of technology to the open (even though it would be nice) and they are maintaining builds for Windows, Mac, Linux, and Android. It is currently available as a C API and a plug-in for Unity. Unreal Engine 4, FMOD, and WWISE plug-ins are “coming soon”.
As for the technology itself, it has quite a few interesting features. As you might expect, it supports HRTF out of the box, which modifies a sound call to appear like it’s coming from a defined direction. The algorithm is based on experimental data, rather than some actual, physical process.
More interesting is their sound propagation and occlusion calculations. They are claiming that this can be raycast, and static scenes can bake some of the work ahead-of-time, which will reduce runtime overhead. Unlike VRWorks Audio or TrueAudio Next, it looks like they’re doing it on the CPU, though. I’m guessing this means that it will mostly raycast to fade between versions of the audio, rather than summing up contributions from thousands of individual rays at runtime (or an equivalent algorithm, like voxel leakage).
Still, this is available now as a C API and a Unity Plug-in, because Valve really likes Unity lately.

Gigabyte have lead with five motherboards, two X370s under Aorus and three B350s with Gigabyte branding. They all share some traits in common such as RGB Fusion with 16.8 million colours to choose from and an application to allow you to customize the light show to your own specifications. It supports control from your phone if you are so addicted to the glow you need to play with your system from across the room.
Smartfan 5 indicates the presence of five headers for fans or pumps that will work with PWM and standard voltage fans, which can draw up to 12V at 2A. The boards also have six temperature sensors to give you feedback on the effectiveness of your cooling and modify it with the included application. Most models will offer Thunderbolt 3, Intel GbE NICs and an ASMedia 2142 USB 3.1 controllers which they claim can provide up to 16Gb/s. All will have high end audio solutions, often featuring a headphone pre-amp and high quality capacitors. There are a lot more features specific to each board, so make sure to click through to check out your favourites.
The Aorus boards, the GA-AX370-Gaming K7 and GA-AX370-GAMING 5 are very similar but if you plan on playing with your BCLK it is the K7 which includes Gigabyte's Turbo B-Clock. The Gigabyte lineup includes the GA-AB350M, GA-AB350-Gaming and GA-AB350-GAMING 3. The GA-AB350M is the only mATX Ryzen board of these five for those looking to build a smaller system. For audiophiles the full size the GAMING 3 includes an ALC1220 codec as opposed to the ALC 887 used on the other two models.
You can expect to see reviews of these boards which offer far more details on perfomance and features after they are released on March 2nd. Full PR under the break.

The Azio Armato is a big aluminium keyboard, with five macro keys located on the lower left, on the upper right are media control buttons beside the large volume knob. The keyboard does come with a wrist rest, which attaches via a magnet so you can choose to remove it at will. The keyboard does not require software, lighting is controlled via keystrokes and macros are recorded by pushing that large REC button and one of the macro keys, then up to up to 31 keys in sequence and the REC button again to save the macro. You can see more of the Armato over at Benchmark Reviews.
"In any case Benchmark Reviews has in hand their Armato Mechanical Gaming Keyboard, model MGK-ARMATO-01.

While AMD's Ryzen lineup and pricing has leaked out, only the top three Ryzen 7 processors are available for pre-order (with availability on March 2nd). Starting at $329 for the eight core sixteen thread Ryzen 7 1700, these processors are aimed squarely at enthusiasts craving top-end performance. It seems that enthusiasts looking for cheaper and better price/performance options for budget gaming and work machines will have to wait a bit for Ryzen 5 and Ryzen 3 which will reportedly launch in the second quarter and second half of 2017 respectively. Two six core Ryzen 5 processors will launch somewhere between April and June with the Ryzen 3 quad cores (along with mobile and "Raven Ridge" APU parts) following in the summer to end-of-year timeframe hopefully hitting that back-to-school and holiday shopping launch windows respectively.
Thanks to leaks, the two six core Ryzen 5 CPUs are the Ryzen 5 1600X at $259 and Ryzen 5 1500 at $229. The Ryzen 5 1600X is a 95W TDP CPU with six cores and twelve threads at 3.6 GHz base to 4.0 GHz boost with 16MB of L3 cache. AMD is pitting this chip against the Intel Core i5 7600K which is a $240 quad core Kaby Lake part sans Hyper-Threading. Meanwhile, the Ryzen 5 1500 is a 65W processor clocked at 3.2 GHz base and 3.5 GHz boost with 16 MB of L3 cache.
Note that the Ryzen 5 1600X features AMD's XFR (extreme frequency) technology which the Ryzen 5 1500 lacks. Both processors are unlocked and can be overclocked, however.
Interestingly, Antony Leather over at Forbes managed to acquire some information on how AMD is making these six core parts. According to his source, AMD is disabling one core (and its accompanying L2 cache) from each four core Core Complex (CCX). Doing this this way (rather than taking two cores from one CCX) should keep things balanced. It also allows AMD to keep all of the processors 16MB of L3 cache enabled and each of the remaining three cores of each complex will be able to access the L3 cache as normal. Previous rumors had suggested that the CCXes were "indivisible" and six cores were not possible, but it appears that AMD is able to safely disable at least one core of a complex without compromising the whole thing. I doubt we will be seeing any odd number core count CPUs from AMD though (like their old try at selling tri-core parts that later were potentially able to be unlocked). I am glad that AMD was able to create six core parts while leaving the entire L3 cache intact.
What is still not clear is whether these six core Ryzen 5 parts are made by physically disabling the core from the complex or if the cores are simply disabled/locked out in the micro code or BIOS/UEFI. It would be awesome if, in the future when yields are to the point where binning is more for product segmentation than because of actual defects, those six core processors could be unlocked!
The top end Ryzen 7 processors are looking to be great performers and a huge leap over Excavator while at least competing with Intel's latest at multi-threaded performance (I will wait for independent benchmarks for single threaded where even from AMD the benchmark scores are close although these benchmark runs look promising). These parts are relatively expensive though, and the cheaper Ryzen 5 and Ryzen 3 (and Raven Ridge APUs) are where AMD will see the most potential sales due to a much bigger market. I am looking forward to seeing more information on the lower end chips and how they will stack up against Intel and its attempts to shift into high gear with moves like enabling Hyper-Threading on lower end Kaby Lake Pentiums and possibly on new Core i5s (that's still merely a rumor though). Intel certainly seems to be taking notice of Ryzen and the reignited competition in the desktop processor space is very promising for consumers!
Are you holding out for a six core or quad core Ryzen CPU or are you considering a jump to the high-end Ryzen 7s?

[H]ard|OCP have been spending a lot of time removing the integrated heatspreader on recent Intel chips to see what effect it has on temperatures under load. Along the way we picked up tips on 3D printing a delidder and thankfully there was not much death along the way. One of their findings from this testing was that it can be beneficial to reattach the lid after changing out the thermal interface material and they have published a guide on how to do so. You will need a variety of tools, from Permatex Red RTV to razor blades, by way of isopropyl alcohol and syringes; as well as a steady hand. You may have many of the items on hand already and none are exceptionally expensive.
"So we have covered a lot about taking your shiny new Intel CPUs apart lately, affectionately known as "delidding." What we have found in our journey is that "relidding" the processor might be an important part of the process as well. But what if you do not have a fancy tool that will help you put Humpty back together again?"

There is an insidious latency gap lurking in your computer between your DRAM and your CPUs L3 cache. The size of the latency depends on your processor as not all L3 cache are created equally but regardless there are wasted CPU cycles which could be reclaimed. Piecemakers Technology, the Industrial Technology Research Institute of Taiwan and Intel are on the case, with a project to design something to fit in that niche between the CPU and DRAM. Their prototype Last Level Cache is a chip with 17ns latency which would improve the efficiency at which L3 cache could be filled to pass onto the next level in the CPU. The Register likens it to the way Intel has fit XPoint between the speed of SSDs and DRAM. It will be interesting to see how this finds its way onto the market.
"Jim Handy of Objective Analysis writes about this: "Furthermore, there's a much larger latency gap between the processor's internal Level 3 cache and the system DRAM than there is between any adjacent cache levels.""

Today FSP Group (a company mainly known for power supplies with headquarters in Taiwan) is launching a new mid tower ATX computer case called the CMT210. The new PC mid-tower features a transparent side window, black angular exterior with LED accents, and a focus on cooling performance. The 460mm x 220mm x 432mm steel case is aimed at gamers and enthusiasts that want to show off their PC internals.
The front of the CMT210 mid tower is dominated by a massive filtered vent that houses up to three 120mm fans or a 360mm water cooling radiator. The large vent with angled “water droplet” mesh is surrounded by a shroud that features colored accents in either black, red, silver, or deep blue depending on the model you choose. Up top the case offers two audio jacks, two USB 3.0 ports, and a single USB 2.0 port. (The USB 3.0 ports can be plugged into a USB 2.0 motherboard header with the included adapter if you are still holding off on upgrading to Kaby Lake or Ryzen.)
The top of the case is flat with no vents, and there are also no vents on the bottom. Instead there is a single 120mm exhaust fan vent at the rear of the case. FSP includes two of its own 120mm LED fans with the case that come pre-installed in the front and back.
The CMT210 is compatible with ATX motherboards, seven PCI slots, three 3.5” and three 2.5” tool-less drive bays, CPU coolers up to 160mm high and graphics cards up to 360mm long, and ATX power supplies (20.5cm). The power supply is bottom mounted in this case and the storage drives are snapped into trays in the bottom-front caddy and motherboard tray. There are cutouts for cable routing but no rubber grommets (not the end of the world, but they are a nice touch).
FSP claims that its new case is designed with "cooling, expansion, and compatibility" in mind. It is available now in the US though pricing is still unknown as retailers have not put up product pages yet. For more information on the CMT210 you can find details on this product page and this video.
I am curious how well the cooling setup will work with only a single exhaust fan especially if you had a multi GPU setup with aftermarket coolers. Hopefully Sebastian can put it through its paces at some point to examine the build quality and cooling prowess claims. If the price is right, it could be a good budget case as it does not look too bad and does not go crazy with LEDs and bling which is nice to see (I may just be getting old though haha).
What are your thoughts on PSU maker FSP Group getting into the case market?

I am not one to recommend preordering anything but there are plenty of consumers out there that are, as you can tell by how quickly the new Ryzen processors are selling. Here is a quick look at three of the system builders offerings you can order as of today.
They offer four different systems, with all but their new Hyper Liquid model using a Corsair H60 CLC for cooling and 8GB of dual channel DDR4. All systems come with a 3-year limited warranty and lifetime tech support
Maingear is more cooling focused, with custom watercooling available in traditional soft tubing and hardline options. They also offer MAINGEAR Redline Overclocking, so your Ryzen powered system will arrive already running at higher that reference frequencies. You will pay a little more but they do put effort into the paint and aesthetics.
Origin's systems start shipping on March 12th, with NEURON, MILLENNIUM and GENESIS desktops which come with free lifetime US-based 24/7 support. They offer Variable Mounting which allows you a choice between four motherboard mounting orientations, choose the appropriate one based on your preferred cooling solution. You can also add remote controlled LEDs and in some models, up to 34 drives can be installed.
Last but not least is NCIX who not only offer several choices of custom systems but also list a wide variety of AM4 motherboards and compatible coolers for you to order individually. The lower end B350 boards look to retail around $150 while some of the high end X370 boards are over $400. The X370 above features two M.2 NVMe PCIe x4 slots with heatshields while the B350 has only one, exposed to the world.
