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.

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:
Introduction and Technical Specifications

The ASUS X99-Deluxe motherboard is among the initial offerings in ASUS' Intel X99 chipset board line. The board supports the latest Intel LGA2011-v3 socket processors as well as DDR4 memory modules. ASUS also integrated and improved upon many of the features from its award-winning Z97 board line into this product, making for a superior synthesis of technology and computing power. The board does not come cheap with an MSRP of $399.99, but its integrated feature set and performance potential more than justifies the X99-Deluxe's premium price.

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).
Revamped Enthusiast Platform
Join us at 12:30pm PT / 3:30pm ET as Intel's Matt Dunford joins us for a live stream event to discuss the release of Haswell-E and the X99 platform!! Find us at http://www.pcper.com/live!!
Sometimes writing these reviews can be pretty anti-climactic. With all of the official and leaked information released about Haswell-E over the last six to nine months, there isn't much more to divulge that can truly be called revolutionary. Yes, we are looking at the new king of the enthusiast market with an 8-core processor that not only brings a 33% increase in core count over the previous generation Ivy Bridge-E and Sandy Bridge-E platforms, but also includes the adoption of the DDR4 memory specification, which allows for high density and high speed memory subsystems.
And along with the new processor on a modified socket (though still LGA2011) comes a new chipset with some interesting new features. If you were left wanting for USB 3.0 or Thunderbolt on X79, then you are going to love what you see with X99. Did you think you needed some more SATA ports to really liven up your pool of hard drives? Retail boards are going to have you covered.
Again, just like last time, you will find a set of three processors that are coming into the market at the same time. These offerings range from the $999 price point and go down to the much more reasonable cost of $389. But this time there are more interesting decisions to be made based on specification differences in the family. Do the changes that Intel made in the sub-$1000 SKUs make it a better or worse buy for users looking to finally upgrade?
Haswell-E: A New Enthusiast Lineup from Intel
Today's launch of the Intel Core i7-5960X processor continues on the company's path of enthusiast branded parts that are built off of a subset of the workstation and server market. It is no secret that some Xeon branded processors will work in X79 motherboards and the same is true of the upcoming Haswell-EP series (with its X99 platform) launching today. As an enthusiast though, I think we can agree that it doesn't really matter how a processor like this comes about, as long as it continues to occur well into the future.
The Core i7-5960X processor is an 8-core, 16-thread design built on what is essentially the same architecture we saw released with the mainstream Haswell parts released in June of 2013. There are some important differences of course, including the lack of integrated graphics and the move from DDR3 to DDR4 for system memory. The underlying microarchitecture remains unchanged, though. Previously known as the Haswell-E platform, the Core i7-5960X continues Intel's trend of releasing enthusiast/workstation grade platforms that are based on an existing mainstream architecture.
Little. Yellow. Different.
Corsair just can't help themselves, they just can't stop building new cases. Obsidian, Carbide, Graphite; the obsession is never ending it seems. That's good news for enthusiasts though as Corsair's entries to the case market have almost always been high quality. Today's official launch of the Graphite 380T, available in yellow, black and white color schemes, brings yet another entry to the Mini-ITX form factor. It's a market that has been getting a lot of attention lately and one that requires more careful thought in design.
With a price of $139-149 depending on color, the Graphite 380T isn't a cheap case by most users descriptions but it is quite unique - both from the look and style as well as the implementation of components. You get a 3-speed fan controller as well as an interior dome light that adds a little character to an exterior that will already get a lot attention. And maybe some comparisons to a Dewalt portable worksite stereo.
The front panel removes with a simple spring-loaded click release and acts as both air inlet and filter for the large 140mm fan included up front.
Welcome Back to Part 2
(Courtesy of Cooler Master)
Welcome back to the second part of our Cooler Master HAF Stacker Series case review. In Part 1 we took a detailed look at the construction, specifications, and features of the HAF Stacker 935 and HAF Stacker 915R/F enclosures.
HAF Stacker 935 Mod-Tower Enclosure
Cooler Master’s new HAF Stacker modular cases offer great flexibility and expandability. You can easily build a dual system in one enclosure by installing a full-size ATX system in the lower mid-tower section with a complete, self-contained mini-ITX system in the HAF 915 chassis up top. The HAF Stacker modular design offers tremendous room with virtually unlimited options for serious water-cooling. And if you want even more room, you can stack HAF case modules on top of each other in a virtually endless combinations!
Dual Peltier Water Chiller
Now in Part 2, we are going to complete our review by checking out component installation, building two complete systems in the Stacker cases (full ATX gaming rig and a mini-ITX based system), and look at various cooling options including the potential to house a full-blown water-cooling system with a Thermoelectric (TEC) water chiller.
HAF Stacker 915R/F Stackable Enclosures
Since the introduction of the Haswell line of CPUs, the Internet has been aflame with how hot the CPUs run. Speculation ran rampant on the cause with theories abounding about the lesser surface area and inferior thermal interface material (TIM) in between the CPU die surface and the underside of the CPU heat spreader. It was later confirmed that Intel had changed the TIM interfacing the CPU die surface to the heat spreader with Haswell, leading to the hotter than expected CPU temperatures. This increase in temperature led to inconsistent core-to-core temperatures as well as vastly inferior overclockability of the Haswell K-series chips over previous generations.
A few of the more adventurous enthusiasts took it upon themselves to use inventive ways to address the heat concerns surrounding the Haswell by delidding the processor. The delidding procedure involves physically removing the heat spreader from the CPU, exposing the CPU die. Some individuals choose to clean the existing TIM from the core die and heat spreader underside, applying superior TIM such as metal or diamond-infused paste or even the Coollaboratory Liquid Ultra metal material and fixing the heat spreader back in place. Others choose a more radical solution, removing the heat spreader from the equation entirely for direct cooling of the naked CPU die. This type of cooling method requires use of a die support plate, such as the MSI Die Guard included with the MSI Z97 XPower motherboard.
Whichever outcome you choose, you must first remove the heat spreader from the CPU's PCB. The heat spreader itself is fixed in place with black RTV-type material ensuring a secure and air-tight seal, protecting the fragile die from outside contaminants and influences. Removal can be done in multiple ways with two of the most popular being the razor blade method and the vise method. With both methods, you are attempting to separate the CPU PCB from the heat spreader without damaging the CPU die or components on the top or bottom sides of the CPU PCB.
