Introduction and Features
Today we have a double header for your reading enjoyment. Not one, but two Platinum Series power supplies from Seasonic. The two latest additions to Seasonic’s flagship product line are the Platinum 1050W and Platinum 1200W PSUs. The power supplies feature tight voltage regulation (±1~2%), quiet operation (fanless mode), and high efficiency (80Plus Platinum certified). Both PSUs are fully modular and come backed by a 7-year warranty.
Seasonic is a well known and highly respected OEM that produces some of the best PC power supplies on the market today. In addition to supplying power supplies to many big-name companies who re-brand the units with their own name, Seasonic also sells a full line of power supplies under the Seasonic name. Both new power supplies feature an improved Hybrid Fan control circuit and upgraded copper conduction bars on the main PCB, which together help increase efficiency and performance.
Seasonic Platinum 1050W & 1200W Special Features
Ultra Tight Voltage Regulation Improved load voltage regulation keeps the voltage fluctuations on the 12V output within +2% and -0% (no negative tolerance), and on the 3.3V and 5V outputs between +1% and -1%, which (under 80 Plus load conditions) results in smooth and stable operation.
Seasonic Hybrid Silent Fan Control The industry first, advanced three-phased thermal control balances between silence and cooling. The Hybrid Silent Fan Control provides three operational stages: Fanless, Silent and Cooling Mode. In addition, a selector switch is provided to allow for manual selection between the Seasonic S2FC (fan control without Fanless Mode) or S3FC (fan control including Fanless Mode).
Reduced Cooling Fan Hysteresis is achieved by a new fan control IC, which optimizes how frequently the fan switches on and off. At 25°C ambient temperature the fan turns on when the load rises above 30% (±5%) and turns off when the load drops below 20% % (±5%). Due to this lag in response the fan switches on and off less frequently, which reduces power loss in Fanless and Silent Mode.
Dual Copper Conduction Bars on the power supply PCB help reduce impedance and minimize voltage drop, which further improves efficiency and performance.
80Plus Platinum The Platinum 1050W & 1200W power supplies are certified in accordance to the 80PLUS organization's Platinum standards, offering performance and energy savings with up to ≥92% efficiency and a true power factor of greater than 0.9 PF.
Full Modular Design (DC to DC) The Seasonic Platinum Series power supplies feature an integrated DC connector panel with onboard VRM (Voltage Regulator Module) that enables not only near perfect DC-to-DC conversion with reduction of current loss/impedance and increase of efficiency but also a fully modular DC cabling that enables maximum flexibility of integration and forward compatibility.

Introduction and Specifications
Today Micron lifted the review embargo on their new M600 SSD lineup. We covered their press launch a couple of weeks ago, but as a recap, the headline new feature is the new Dynamic Write Acceleration feature. As this is a new (and untested) feature that completely changes the way an SSD must be tested, we will be diving deep on this one later in this article. For the moment, let's dispose with the formalities.
Here are the samples we received for testing:
It's worth noting that since all M600 models use 16nm 128Gbit dies, packaging is expected to have a negligible impact on performance. This means the 256GB MSATA sample should perform equally to its 2.5" SATA counterpart. The same goes for comparisons against M.2 form factor units. More detail is present in the specs below:
Highlights from the above specs are the increased write speeds (no doubt thanks to Dynamic Write Acceleration) and improved endurance figures. For reference, the prior gen Micron models were rated at 72TB (mostly regardless of capacity), so seeing figures upwards of 400TB indicates Micron's confidence in their 16nm process.
Sorry to disappoint here, but the M600 is an OEM targeted drive, meaning its 'packaging' will likely be the computer it comes installed in. If you manage to find it through a reseller, it will likely come in OEM-style brown/white box packaging.
We have been evaluating these samples for just under a week and have logged *many* hours on them, so let's get to it!
One Small Step
While most articles surrounding the iPhone 6 and iPhone 6 Plus this far have focused around user experience and larger screen sizes, performance, and in particular the effect of Apple's transition to the 20nm process node for the A8 SoC have been our main questions regarding these new phones. Naturally, I decided to put my personal iPhone 6 though our usual round of benchmarks.
First, let's start with 3DMark.
Comparing the 3DMark scores of the new Apple A8 to even the last generation A7 provides a smaller improvement than we are used to seeing generation-to-generation with Apple's custom ARM implementations. When you compare the A8 to something like the NVIDIA Tegra K1, which utilizes desktop-class GPU cores, the overall score blows Apple out of the water. Even taking a look at the CPU-bound physics score, the K1 is still a winner.
A 78% performance advantage in overall score when compared the A8 shows just how much of a powerhouse NVIDIA has with the K1. (Though clearly power envelopes are another matter entirely.)
If we look at more CPU benchmarks, like the browser-based Google Octane and SunSpider tests, the A8 starts to shine more.
While the A8 edges out the A7 to be the best performing device and 54% faster than the K1 in SunSpider, the A8 and K1 are neck and neck in the Google Octane benchmark.
Moving back to a graphics heavy benchmark, GFXBench's Manhattan test, the Tegra K1 has a 75% percent performance advantage over the A8 though it is 36% faster than the previous A7 silicon.
These early results are certainly a disappointment compared to the usual generation-to-generation performance increase we see with Apple SoCs.
However, the other aspect to look at is power efficiency. With normal use I have noticed a substantial increase in battery life of my iPhone 6 over the last generation iPhone 5S. While this may be due to a small (about 1 wH) increase in battery capacity, I think more can be credited to this being an overall more efficient device. Certain choices like sticking to a highly optimized Dual Core CPU design and Quad Core GPU, as well as a reduction in process node to 20nm all contribute to increased battery life, while surpassing the performance of the last generation Apple A7.
In that way, the A8 moves the bar forward for Apple and is a solid first attempt at using the 20nm silicon technology at TSMC. There is a strong potential that further refined parts (like the expected A8x for the iPad revisions) Apple will be able to further surpass 28nm silicon in performance and efficiency.

Here they come - the G-Sync monitors are finally arriving at our doors! A little over a month ago we got to review the ASUS ROG Swift PG278Q, a 2560x1440 144 Hz monitor that was the first retail-ready display to bring NVIDIA's variable refresh technology to consumers. It was a great first option with a high refresh rate along with support for ULMB (ultra low motion blur) technology, giving users a shot at either option.
Today we are taking a look at our second G-Sync monitor that will hit streets sometime in mid-October with an identical $799 price point. The Acer XB280HK is a 28-in 4K monitor with a maximum refresh rate of 60 Hz and of course, support for NVIDIA G-Sync.
The Acer XB280HK, first announced at Computex in June, is the first 4K monitor on the market to be announced with support for variable refresh. It isn't that far behind the first low-cost 4K monitors to hit the market, period: the ASUS PB287Q and the Samsung U28D590D both shipped in May of 2014 with very similar feature sets, minus G-Sync. I discussed much of the general usability benefits (and issues) that arose when using a consumer 4K panel with Windows 8.1 in those reviews, so you'll want to be sure you read up on that in addition to the discussion of 4K + G-Sync we'll have today.
While we dive into the specifics on the Acer XB280HK monitor today, I will skip over most of the discussion about G-Sync, how it works and why we want it. In our ASUS PG278Q review I had a good, concise discussion on the technical background of NVIDIA G-Sync technology and how it improves gaming.
The idea of G-Sync is pretty easy to understand, though the implementation method can get a bit more hairy. G-Sync introduces a variable refresh rate to a monitor, allowing the display to refresh at wide range of rates rather than at fixed intervals. More importantly, rather than the monitor dictating what rate this refresh occurs at to the PC, the graphics now tells the monitor when to refresh in a properly configured G-Sync setup. This allows a monitor to match the refresh rate of the screen to the draw rate of the game being played (frames per second) and that simple change drastically improves the gaming experience for several reasons.
Introduction and Technical Specifications
Courtesy of Noctua
Noctua is a well known player in the CPU cooling business with their focus on high quality solutions that don't kill your eardrums. The NH-D15 cooler is their current flagship product, building upon the design of their much loved NH-D14 cooler for an even higher performance product offering. The NH-D15 is composed of dual cooling towers, threaded through by six heat pipes. The heat pipes and copper base are all nickel-plated, giving the unit the signature Noctua look. We put the NH-D15 up against other high-performance solutions to best gage its cooling abilities. High performance comes at a cost with the NH-D15 being no exception at a $99.99 MSRP.

The NH-D15 incorporates everything that Noctua has learned in designing its NH-D14 and U-series coolers, coming up with an extreme performance product that maintains almost universal motherboard compatibility. The cooler features twin 150mm wide cooling towers with airflow provided by dual NF-A15 150mm, 1500RPM fans. The heat transfers from the copper base plate to the aluminum radiator towers via six copper heat pipes. The copper base and heat pipes are all nickel-plated, providing scratch and corrosion resistance without affecting thermal transfer capabilities. To ensure optimal acoustics, the NH-A15 fans have rubber corner guards on all four corners to minimize fan vibration and vibration transfer to the radiator. The CPU base plate is seamless and polished to a mirror finish, ensuring an optimal mating surface.

New quote from Samsung:
"We acknowledge the recent issue associated with the Samsung 840 EVO SSDs and are qualifying a firmware update to address the issue. While this issue only affects a small subset of all 840 EVO users, we regret any inconvenience experienced by our customers. A firmware update that resolves the issue will be available on the Samsung SSD website soon. We appreciate our customer’s support and patience as we work diligently to resolve this issue."
** End edit 2 **
Over the past week or two, there have been growing rumblings from owners of Samsung 840 and 840 EVO SSDs. A few reports scattered across internet forums gradually snowballed into lengthy threads as more and more people took a longer look at their own TLC-based Samsung SSD's performance. I've spent the past week following these threads, and the past few days evaluating this issue on the 840 and 840 EVO samples we have here at PC Perspective. This post is meant to inform you of our current 'best guess' as to just what is happening with these drives, and just what you should do about it.
The issue at hand is an apparent slow down in the reading of 'stale' data on TLC-based Samsung SSDs. Allow me to demonstrate:
You might have seen what looks like similar issues before, but after much research and testing, I can say with some confidence that this is a completely different and unique issue. The old X25-M bug was the result of random writes to the drive over time, but the above result is from a drive that only ever saw a single large file write to a clean drive. The above drive was the very same 500GB 840 EVO sample used in our prior review. It did just fine in that review, and at afterwards I needed a quick temporary place to put a HDD image file and just happened to grab that EVO. The file was written to the drive in December of 2013, and if it wasn't already apparent from the above HDTach pass, it was 442GB in size. This brings on some questions:
- If random writes (i.e. flash fragmentation) are not causing the slow down, then what is?
- How long does it take for this slow down to manifest after a file is written?
The GM204 Architecture
James Clerk Maxwell's equations are the foundation of our society's knowledge about optics and electrical circuits. It is a fitting tribute from NVIDIA to include Maxwell as a code name for a GPU architecture and NVIDIA hopes that features, performance, and efficiency that they have built into the GM204 GPU would be something Maxwell himself would be impressed by. Without giving away the surprise conclusion here in the lead, I can tell you that I have never seen a GPU perform as well as we have seen this week, all while changing the power efficiency discussion in as dramatic a fashion.
To be fair though, this isn't our first experience with the Maxwell architecture. With the release of the GeForce GTX 750 Ti and its GM107 GPU, NVIDIA put the industry on watch and let us all ponder if they could possibly bring such a design to a high end, enthusiast class market. The GTX 750 Ti brought a significantly lower power design to a market that desperately needed it, and we were even able to showcase that with some off-the-shelf PC upgrades, without the need for any kind of external power.
That was GM107 though; today's release is the GM204, indicating that not only are we seeing the larger cousin of the GTX 750 Ti but we also have at least some moderate GPU architecture and feature changes from the first run of Maxwell. The GeForce GTX 980 and GTX 970 are going to be taking on the best of the best products from the GeForce lineup as well as the AMD Radeon family of cards, with aggressive pricing and performance levels to match. And, for those that understand the technology at a fundamental level, you will likely be surprised by how much power it requires to achieve these goals. Toss in support for things like a new AA method, Dynamic Super Resolution, and even improved SLI performance and you can see why doing it all on the same process technology is impressive.
The NVIDIA Maxwell GM204 Architecture
The NVIDIA Maxwell GM204 graphics processor was built from the ground up with an emphasis on power efficiency. As it was stated many times during the technical sessions we attended last week, the architecture team learned quite a bit while developing the Kepler-based Tegra K1 SoC and much of that filtered its way into the larger, much more powerful product you see today. This product is fast and efficient, but it was all done while working on the same TSMC 28nm process technology used on the Kepler GTX 680 and even AMD's Radeon R9 series of products.
The fundamental structure of GM204 is setup like the GM107 product shipped as the GTX 750 Ti. There is an array of GPCs (Graphics Processing Clustsers), each comprised of multiple SMs (Streaming Multiprocessors, also called SMMs for this Maxwell derivative) and external memory controllers. The GM204 chip (the full implementation of which is found on the GTX 980), consists of 4 GPCs, 16 SMMs and four 64-bit memory controllers.
Introduction, Specifications and Packaging
It seems a lot of folks have been incorporating Silicon Motion's SM2246EN controller into their product lines. We first reviewed the Angelbird SSD wrk, but only in a 512GB capacity. We then reviewed a pair of Corsair Force LX's (256GB and 512GB). ADATA has joined the club with their new Premier SP610 product line, and today we are going to take a look at all available capacities of this new model:
It's fortunate that ADATA was able to sample us a full capacity spread, as this will let us evaluate all shipping SSD capacites that exist for the Silicon Motion SM2246EN controller.
Introduction: A Crowded Market
The case market is not only saturated at every conceivable price point, but there is enough of a builder’s DNA in their enclosure selection that making recommendations in this area can be a galvanizing undertaking. The enclosure with less usefulness can have perceived deficiencies mitigated by style, and vice versa. For some, style is the most important attribute. But functionality alone, when unnecessary elements are stripped away, can be attractive as well. Here we have a bit of both.
Fractal Design is a Swedish company specializing in computer enclosures, though much like Corsair (which started life as a memory company) they have diversified their product offerings with a line power supplies and all-in-one liquid CPU coolers, as well as case fans and accessories. The company cites Scandinavian design as the influence behind their aesthetic, with the minimalist approach of 'less is more'. With the “Core” series Fractal Design has just what that nomenclature indicates. An entry-level offering that still provides the essentials for a solid build.
With the Core 3300 ATX case the basics are all represented, and it seems that nothing has been included for artistic reasons alone. The Core 3300 does not have a side window, and inside you won't see convenience features like toolless drive bays. Ultimately it’s a rather nondescript matte black case that’s mostly steel, but there are touches that help it stand out in this particular segment of a crowded market.
ECS hosted a press event in the third week of August to unveil its new product lineup and corporate direction. The press event, named "Live, Liva, Lead, L337", lays out the important aspects of the "new ECS" and its intended market direction. They introduced the LIVA mini computer with integrated 32GB and 64GB integrated SSDs, their Z97-based product line-up, and the North America LIVA design contest.
Their naming of the event was apropos to their renewed corporate vision with the first two terms, Live and LIVA, referencing their LIVA mini-PC platform. ECS developed the name LIVA by combining the words Live and Viva (Life in Spanish), signifying the LIVA line's aim at integrating itself into your daily routine and providing the ability to live a better life. Lead signifies ECS' desire to become a market leader in the Mini-PC space with their LIVA platform as well as become a more dominant player in the PC space. The last term, L337, is a reference to their L337 Gaming line of motherboards, a clear reminder of their Z97 offerings to be unveiled.
ECS seeks to consolidate its product lines, re-focusing its energy on what it excels at - offering quality products at reasonable prices. ECS seeks to leverage its corporate partnerships and design experience to build products equivalent to competitor lines at a much reduced cost to the end user. This renewed focus on quality and the end user led to a much revised Z97 board lineup in comparison to its Z87-based offerings. Additionally, their newly introduced mini-PC line, branded LIVA, seeks to offer a cheaper all-in-one alternative to the Intel NUC and GIGABYTE BRIX systems.

Core M 5Y70 Early Testing
During a press session today with Intel, I was able to get some early performance results on Broadwell-Y in the form of the upcoming Core M 5Y70 processor.
Testing was done on a reference design platform code named Llama Mountain and at the heart of the system is the Broadwell-Y designed dual-core CPU, the Core M 5Y70, which is due out later this year. Power consumption of this system is low enough that Intel has built it with a fanless design. As we posted last week, this processor has a base frequency of just 1.10 GHz but it can boost as high as 2.6 GHz for extra performance when it's needed.
Before we dive into the actual result, you should keep in mind a couple of things. First, we didn't have to analyze the systems to check driver revisions, etc., so we are going on Intel's word that these are setup as you would expect to see them in the real world. Next, because of the disjointed nature of test were were able to run, the comparisons in our graphs aren't as great as I would like. Still, the results for the Core M 5Y70 are here should you want to compare them to any other scores you like.
First, let's take a look at old faithful: CineBench 11.5.
UPDATE: A previous version of this graph showed the TDP for the Intel Core M 5Y70 as 15 watts, not the 4.5 watt listed here now. The reasons are complicated. Even though the Intel Ark website lists the TDP of the Core M 5Y70, Intel has publicly stated the processor will make very short "spikes" at 15 watts when in its highest Turbo Boost modes. It comes to a discussion of semantics really. The cooling capability of the tablet is only targeted to 4.5-6.0 watts and those very short 15 watt spikes can be dissipated without the need for extra heatsink surface...because they are so short. SDP anyone? END UPDATE
With a score of 2.77, the Core M 5Y70 processor puts up an impressive fight against CPUs with much higher TDP settings. For example, Intel's own Pentium G3258 gets a score of 2.71 in CB11, and did so with a considerably higher thermal envelope. The Core i3-4330 scores 38% higher than the Core M 5Y70 but it requires a TDP 3.6-times larger to do so. Both of AMD's APUs in the 45 watt envelope fail to keep up with Core M.
Server and Workstation Upgrades
Today, on the eve of the Intel Developer Forum, the company is taking the wraps off its new server and workstation class high performance processors, Xeon E5-2600 v3. Known previously by the code name Haswell-EP, the release marks the entry of the latest microarchitecture from Intel to multi-socket infrastructure. Though we don't have hardware today to offer you in-house benchmarks quite yet, the details Intel shared with me last month in Oregon are simply stunning.
Starting with the E5-2600 v3 processor overview, there are more changes in this product transition than we saw in the move from Sandy Bridge-EP to Ivy Bridge-EP. First and foremost, the v3 Xeons will be available in core counts as high as 18, with HyperThreading allowing for 36 accessible threads in a single CPU socket. A new socket, LGA2011-v3 or R3, allows the Xeon platforms to run a quad-channel DDR4 memory system, very similar to the upgrade we saw with the Haswell-E Core i7-5960X processor we reviewed just last week.
The move to a Haswell-based microarchitecture also means that the Xeon line of processors is getting AVX 2.0, known also as Haswell New Instructions, allowing for 2x the FLOPS per clock per core. It also introduces some interesting changes to Turbo Mode and power delivery we'll discuss in a bit.
Maybe the most interesting architectural change to the Haswell-EP design is per core P-states, allowing each of the up to 18 cores running on a single Xeon processor to run at independent voltages and clocks. This is something that the consumer variants of Haswell do not currently support - every cores is tied to the same P-state. It turns out that when you have up to 18 cores on a single die, this ability is crucial to supporting maximum performance on a wide array of compute workloads and to maintain power efficiency. This is also the first processor to allow independent uncore frequency scaling, giving Intel the ability to improve performance with available headroom even if the CPU cores aren't the bottleneck.
A few days with some magic monitors
Last month friend of the site and technology enthusiast Tom Petersen, who apparently does SOMETHING at NVIDIA, stopped by our offices to talk about G-Sync technology. A variable refresh rate feature added to new monitors with custom NVIDIA hardware, G-Sync is a technology that has been frequently discussed on PC Perspective.
The first monitor to ship with G-Sync is the ASUS ROG Swift PG278Q - a fantastic 2560x1440 27-in monitor with a 144 Hz maximum refresh rate. I wrote a glowing review of the display here recently with the only real negative to it being a high price tag: $799. But when Tom stopped out to talk about the G-Sync retail release, he happened to leave a set of three of these new displays for us to mess with in a G-Sync Surround configuration. Yummy.
So what exactly is the current experience of using a triple G-Sync monitor setup if you were lucky enough to pick up a set? The truth is that the G-Sync portion of the equation works great but that game support for Surround (or Eyefinity for that matter) is still somewhat cumbersome.
In this quick impressions article I'll walk through the setup and configuration of the system and tell you about my time playing seven different PC titles in G-Sync Surround.
Introduction, Specifications and Packaging
We first looked at the Silicon Motion 2246EN controller in our Angelbird SSD wrk review. In that review, we noted the highest sequential performance seen in any SATA SSD reviewed to date. Eager to expand our testing to include additional vendors and capacities, our next review touching on this controller is the Corsair Force LX series of SSDs. The Force LX Series is available in 128GB, 256GB, and 512GB capacities, and today we will look at the 256GB and 512GB iterations of this line:

ASUS built the X99-Deluxe to take the punishment associated with a high performance system, integrating a 8+4 phase digital power system for the CPU and DDR4 DRAM power needs. Also integrated is the latest version of ASUS' Digi+ power power regulation circuitry along with 5k rated solid capacitors.
Introduction, Specifications and Packaging
Today I'm going to talk to you about something you might not have thought you needed, but once you realize what this new device can do, you might just want one. Imagine a Western Digital My Cloud, but only smaller, battery powered, and wireless. You could fill it with a bunch of movies, music, and other media for something like an upcoming family road trip. If said device could create its own wireless hotspot, the kids could connect to it via their tablets or other portable devices and watch their movie of choice during the drive. Once you are at your destination and snapping a bunch of photos, it would also be handy if this imaginary device could also mount SD cards for sharing recently taken photos with others on your trip. A bonus might be the ability to store a back-up of those SD cards as they become full, or maybe even empty them for folks without a lot of SD capacity available. As a final bonus, make all of this work in such a way that you could pull off an entire trip with *only* mobile devices and tablets - *without* a PC or a Mac. Think all of that can happen? It can now!:
Behold the WD My Passport Wireless!
Tonga GPU Features
On December 22, 2011, AMD launched the first 28nm GPU based on an architecture called GCN on the code name Tahiti silicon. That was the release of the Radeon HD 7970 and it was the beginning of an incredibly long adventure for PC enthusiasts and gamers. We eventually saw the HD 7970 GHz Edition and the R9 280/280X releases, all based on essentially identical silicon, keeping a spot in the market for nearly 3 years. Today AMD is launching the Tonga GPU and Radeon R9 285, a new piece of silicon that shares many traits of Tahiti but adds support for some additional features.
Replacing the Radeon R9 280 in the current product stack, the R9 285 will step in at $249, essentially the same price. Buyers will be treated to an updated feature set though including options that were only previously available on the R9 290 and R9 290X (and R7 260X). These include TrueAudio, FreeSync, XDMA CrossFire and PowerTune.
Many people have been calling this architecture GCN 1.1 though AMD internally doesn't have a moniker for it. The move from Tahiti, to Hawaii and now to Tonga, reveals a new design philosophy from AMD, one of smaller and more gradual steps forward as opposed to sudden, massive improvements in specifications. Whether this change was self-imposed or a result of the slowing of process technology advancement is really a matter of opinion.
Pushing the 8 Cores
It seems like yesterday when I last talked about an AMD refresh! Oh wait, it almost was. Some weeks ago I was able to cover the latest AMD APU offerings that helped to flesh out the Kaveri lineup. We thought AMD was done for a while. Color us wrong. AMD pulled out all the stops and set up an AM3+ refresh! There is a little excitement here, I guess. I am trying to contain the tongue-in-cheek lines that I am oh-so-tempted to write.
AMD is refreshing their FX lineup in the waning days of Summer!
Let me explain the situation from my point of view. The FX lineup for AM3+ has not done a whole lot since the initial release of the Piledriver based FX-8350 and family (Vishera). Piledriver was a pretty significant update from Bulldozer as it slightly improved IPC and greatly improved power consumption (all the while helping to improve clockspeed by a small degree). There were two updates before this one, but they did not receive nearly as much coverage. These updates were the FX-6350 and the FX-9000 series. The FX-6350 is quite popular with the budget enthusiast crowd who still had not moved over to the Intel side of the equation. The FX-9000 series were OEM only initially and reaching up to $1000 at the high end. During that time since the original Vishera chips were released, we have seen the Intel Ivy Bridge and Haswell architectures (with a small refresh with Haswell with the 2nd gen products and the latest Socket 2011 units).
