Technical Specifications

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.

The answer to the two most important questions are as follows, the GTX 980 will cost you around $560 compared to the $500 for an R9 290X and the GTX 970 an attractive $330 compared to $380 for an R9 290.  Availability is hard to predict but the cards will be shipping soon and you can pre-order your choice of card by following the links on the last page of Ryan's review.  Among all the new features that have been added to this new GPU one of the most impressive is the power draw, as you can see in [H]ard|OCP's review this card pulls 100W less than the 290X at full load although it did run warmer than the 290X Double Dissipation card which [H] compared it to, something that may change with a 980 bearing a custom cooler.  Follow those links to see the benchmarking results of this card, both synthetic and in game.

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.

IMG_9754.JPG

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.

GeForce_GTX_980_Block_Diagram_FINAL.png

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.

MSI's overclocked R9 285 GAMING OC

Subject: General Tech | September 8, 2014 - 02:34 PM |
Tagged: video, tonga, radeon, r9 285, gcn. gcn 1.1, freesync, factory overclocked, amd, 285

MSI's Radeon R9 285 GAMING OC does not yet show up for sale but with it's factory overclock may arrive at a slightly higher price than the MSRP of $250.  The RAM remains at the default 5.5 GHz but the GPU has been bumped up 55MHz to 973MHz out of the box and could likely be pushed higher as MSI has included the usual suspects on this card, Twin Frozr IV Advanced and Military Class 4 components.  In [H]ard|OCP's testing the card was well matched by the GTX 760, the HD 285 won more than it lost, but not always and not by much.  Compared to the HD 280 not only did the new Tonga card usually provide better performance but the additional feature the GPU supports, of which FreeSync is only one, make the HD 285 the clear winner in that contest.  Check their full review for benchmarks.

Ryan reviewed Sapphire's model here.

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.

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.

Tagged: video, Intel, X99, Haswell-E, core i7-5960x, 5960X, ddr4

Though my review of the Intel Core i7-5960X Haswell-E processor was posted earlier today, we hosted a live stream later in the afternoon where Allyn and I talked about the launch. We were also able to welcome Matt Dunford, Princpal Evangelist at Intel to talk about his role in the Haswell-E release, the future of the platform, how DDR4 memory fits into it all and much more.

The video is embeded in the processor review now as well but I have included it separately below for those of you that want to jump straight in.

My thanks goes out to Matt from Intel for joining us on the live stream and to all the viewers that came by to submit questions and participate!
