Installation and Overview
While once a very popular way to cool your PC, the art of custom water loops tapered off in the early 2000s as the benefits of better cooling, and overclocking in general, met with diminished returns. In its place grew a host of companies offering closed loop system, individually sealed coolers for processors and even graphics cards that offered some of the benefits of standard water cooling (noise, performance) without the hassle of setting up a water cooling configuration manually.
A bit of a resurgence has occurred in the last year or two though where the art and styling provided by custom water loop cooling is starting to reassert itself into the PC enthusiast mindset. Some companies never left (EVGA being one of them), but it appears that many of the users are returning to it. Consider me part of that crowd.
During a live stream we held with EVGA's Jacob Freeman, the very first prototype of the EVGA Hydro Copper was shown and discussed. Lucky for us, I was able to coerce Jacob into leaving the water block with me for a few days to do some of our testing and see just how much capability we could pull out of the GM204 GPU and a GeForce GTX 980.
Our performance preview today will look at the water block itself, installation, performance and temperature control. Keep in mind that this is a very early prototype, the first one to make its way to US shores. There will definitely be some changes and updates (in both the hardware and the software support for overclocking) before final release in mid to late October. Should you consider this ~$150 Hydro Copper water block for your GTX 980?

Move over Super Best Friends, the Dynamic Super Resolution Duo is here to slay the evil Jaggies! Ryan covered NVIDIA's new DSR in his review of the new Maxwell cards and how it can upsample a monitor with a resolution of 2560x1440 or lower to much higher resolutions using a process similar to supersampling but is in fact a 13-tap gaussian filter. That is important because supersampling would have some interesting challenges rendering 2560x1440 on a 1080p monitor. DSR gives you a much wider choice of resolutions as you can see in the Guild Wars screenshot below, allowing you to choose a variety of multipliers to your displays native resolution to give your game a much smoother look. The Tech Report has assembled a variety of screenshots from games with different DSR and AA settings which you can examine with your own eyeballs to see what you think.
"One of the more intriguing capabilities Nvidia introduced with the GeForce GTX 970 and 980 is a feature called Dynamic Super Resolution, or DSR, for short. Nvidia bills it as a means of getting 4K quality on a 2K display. How good is it? We take a look."

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.
"Today NVIDIA launches its newest Maxwell GPU. There will be two new GPUs, the GeForce GTX 980 and GeForce GTX 970. These next generation GPUs usher in new features and performance that move the gaming industry forward. We discuss new features, architecture, and evaluate the gameplay performance against the competition."

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.

Details and photographs of the GeForce GTX 980 are leaking on various forums and websites. Based on the Maxwell architecture, it is supposed to be faster and more efficient than Kepler while being manufactured on an identical, 28nm fab process. While we were uncertain before, it now looks like the GTX 980 will be its formal name, as seen in leaked photographs, below.

As expected, the cooler is a continuation of NVIDIA's reference cooler, as seen on recent high-end graphics cards (such as the GeForce Titan). Again, this is not a surprise. The interesting part is that it is rated for about 250W whereas Maxwell is rumored to draw 180W. While the reference card has two six-pin PCIe power connectors, I am curious to see if the excess cooling will lead to interesting overclocks. That is not even mentioning what the AIB partners can do.

Beyond its over-engineering for Maxwell's TDP, it also includes a back plate.
Its display connectors have been hotly anticipated. As you can see above, the GTX 980 has five outputs: three DisplayPort, one HDMI, and one DVI. Which version of HDMI? Which version of DisplayPort? No clue at the moment. There has been some speculation regarding HDMI 2.0, and the DisplayPort 1.3 standard was just released to the public today, but I would be pleasantly surprised if even one of these made it in.

Earlier today we had NVIDIA's Tom Petersen in studio to discuss the retail availability of G-Sync monitors as well as to get hands on with a set of three ASUS ROG Swift PG278Q monitors running in G-Sync Surround! It was truly an impressive sight and if you missed any of it, you can catch the entire replay right here.
Even if seeing the ASUS PG278Q monitor again doesn't interest you (we have our full review of the monitor right here), you won't want to miss the very detailed Q&A that occurs, answering quite a few reader questions about the technology. Covered items include:
- Potential added latency of G-Sync
- Future needs for multiple DP connections on GeForce GPUs
- Upcoming 4K and 1080p G-Sync panels
- Can G-Sync Surround work through an MST Hub?
- What happens to G-Sync when the frame rate exceeds the panel refresh rate? Or drops below minimum refresh rate?
- What does that memory on the G-Sync module actually do??
- A demo of the new NVIDIA SHIELD Tablet capabilities
- A whole lot more!
Another big thank you to NVIDIA and Tom Petersen for stopping out our way and for spending the time to discuss these topics with our readers. Stay tuned here at PC Perspective as we will have more thoughts and reactions to G-Sync Surround very soon!!

Ryan was not the only one to test the ASUS ROG Swift PG278Q G-Sync monitor, Overclockers Club also received a model to test out. Their impressions of the 27" 2560 x 1440 TN panel were very similar, once they saw this monitor in action going back to their 30-inch 60Hz IPS monitor was not as enjoyable as once it was. The only bad thing they could say about the display was the MSRP, $800 is steep for any monitor and makes it rather difficult to even consider getting two or more of them for a multiple display system.
”When you get down to it, the facts are that even with a TN panel being used for the high refresh rate, the ASUS ROG Swift PG278Q G-Sync monitor delivers great picture quality and truly impressive gaming. I could go on all day long about how smooth each of the games played while testing this monitor, but ultimately not be able to show you without having you sit at the desk with me. No stuttering, no tearing, no lag; it's like getting that new car and having all the sales hype end up being right on the money. When I flip back and forth between my 60Hz monitor and the PC278Q, its like a night and day experience.”

The Waiting Game
NVIDIA G-Sync was announced at a media event held in Montreal way back in October, and promised to revolutionize the way the display and graphics card worked together to present images on the screen. It was designed to remove hitching, stutter, and tearing -- almost completely. Since that fateful day in October of 2013, we have been waiting. Patiently waiting. We were waiting for NVIDIA and its partners to actually release a monitor that utilizes the technology and that can, you know, be purchased.
In December of 2013 we took a look at the ASUS VG248QE monitor, the display for which NVIDIA released a mod kit to allow users that already had this monitor to upgrade to G-Sync compatibility. It worked, and I even came away impressed. I noted in my conclusion that, “there isn't a single doubt that I want a G-Sync monitor on my desk” and, “my short time with the NVIDIA G-Sync prototype display has been truly impressive…”. That was nearly 7 months ago and I don’t think anyone at that time really believed it would be THIS LONG before the real monitors began to show in the hands of gamers around the world.
Since NVIDIA’s October announcement, AMD has been on a marketing path with a technology they call “FreeSync” that claims to be a cheaper, standards-based alternative to NVIDIA G-Sync. They first previewed the idea of FreeSync on a notebook device during CES in January and then showed off a prototype monitor in June during Computex. Even more recently, AMD has posted a public FAQ that gives more details on the FreeSync technology and how it differs from NVIDIA’s creation; it has raised something of a stir with its claims on performance and cost advantages.
That doesn’t change the product that we are reviewing today of course. The ASUS ROG Swift PG278Q 27-in WQHD display with a 144 Hz refresh rate is truly an awesome monitor. What did change is the landscape, from NVIDIA's original announcement until now.

Today Acer unveiled a new Chromebook powered by an NVIDIA Tegra K1 processor. The aptly-named Chromebook 13 is 13-inch thin and light notebook running Google’s Chrome OS with up to 13 hours of battery life and three times the graphical performance of existing Chromebooks using Intel Bay Trail and Samsung Exynos processors.
The Chromebook 13 is 18mm thick and comes in a white plastic fanless chassis that hosts a 13.3” display, full size keyboard, trackpad, and HD webcam. The Chromebook 13 will be available with a 1366x768 or 1920x1080 resolution panel depending on the particular model (more on that below).
Beyond the usual laptop fixtures, external I/O includes two USB 3.0 ports, HDMI video output, a SD card reader, and a combo headphone/mic jack. Acer has placed one USB port on the left side along with the card reader and one USB port next to the HDMI port on the rear of the laptop. Personally, I welcome the HDMI port placement as it means connecting a second display will not result in a cable invading the mousing area should i wish to use a mouse (and it’s even south paw friendly Scott!).
The Chromebook 13 looks decent from the outside, but it is the internals where the device gets really interesting. Instead of going with an Intel Bay Trail (or even Celeron/Core i3), Acer has opted to team up with NVIDIA to deliver the world’s first NVIDIA-powered Chromebook.
Specifically, the Chromebook 13 uses a NVIDIA Tegra K1 SoC, up to 4GB RAM, and up to 32GB of flash storage. The K1 offers up four A15 CPU cores clocked at 2.1GHz, and a graphics unit with 192 Kepler-based CUDA cores. Acer rates the Chromebook 13 at 11 hours with the 1080p panel or 13 hours when equipped with the 1366x768 resolution display. Even being conservative, the Chromebook 13 looks to be the new leader in Chromebook battery life (with the previous leader claiming 11 hours).
A graph comparing WebGL performance between the NVIDIA Tegra K1, Intel (Bay Trail) Celeron N2830, Samsung Exynos 5800, and Samsung Exynos 5250. Results courtesy NVIDIA.
The Tegra K1 is a powerful little chip, and it is nice to see NVIDIA get a design win here. NVIDIA claims that the Tegra K1, which is rated at 326 GFLOPS of compute performance, offers up to three times the graphics performance of the Bay Trail N2830 and Exynos 5800 SoCs. Additionally, the K1 reportedly uses slightly less power and delivers higher multi-tasking performance. I’m looking forward to seeing independent reviews in this laptop formfactor and hoping that the chip lives up to its promises.
The Chromebook 13 is currently up for pre-order and will be available in September starting at $279. The Tegra K1-powered laptop will hit the United States and Europe first, with other countries to follow. Initially, the Europe roll-out will include “UK, Netherlands, Belgium, Denmark, Sweden, Finland, Norway, France, Germany, Russia, Italy, Spain, South Africa and Switzerland.”
Acer is offering three consumer SKUs and one education SKU that will be exclusively offering through a re-seller. Please see the chart below for the specifications and pricing.
|Acer Chromebook 13 Models||System Memory (RAM)||Storage (flash)||Display||Price MSRP|
|CB5-311-T9B0||2GB||16GB||1920 x 1080||$299.99|
|CB5-311-T1UU||4GB||32GB||1920 x 1080||$379.99|
|CB5-311-T7NN - Base Model||2GB||16GB||1366 x 768||$279.99|
|Educational SKU (Reseller Only)||4GB||16GB||1366 x 768||$329.99|
Intel made some waves in the Chromebook market earlier this year with the announcement of several new Intel-powered Chrome devices and the addition of conflict-free Haswell Core i3 options. It seems that it is now time for the ARM(ed) response. I’m interested to see how NVIDIA’s newest model chip stacks up to the current and upcoming Intel x86 competition in terms of graphics power and battery usage.
As far as Chromebooks go, if the performance is at the point Acer and NVIDIA claim, this one definitely looks like a decent option considering the price. I think a head-to-head between the ASUS C200 (Bay Trail N2830, 2GB RAM, 16GB eMMC, and 1366x768 display at $249.99 MSRP) and Acer Chromebook 13 would be interesting as the real differentiator (beyond aesthetics) is the underlying SoC. I do wish there was a 4GB/16GB/1080p option in the Chromebook 13 lineup though considering the big price jump to get 4GB RAM (mostly as a result of the doubling of flash) in the $379.99 model at, say, $320 MSRP.
