GeForce GTX 980M Performance Testing

When NVIDIA launched the GeForce GTX 980 and GTX 970 graphics cards last month, part of the discussion at our meetings also centered around the mobile variants of Maxwell. The NDA was a bit later though and Scott wrote up a short story announcing the release of the GTX 980M and the GTX 970M mobility GPUs. Both of these GPUs are based on the same GM204 design as the desktop cards, though as you should have come to expect by now, do so with lower specifications than the similarly-named desktop options. Take a look:

  GTX 980M GTX 970M
GTX 980

GTX 970

GTX 880M
(Laptop)
CUDA Cores 1536 1280 2048 1664 1536

Perf. (TFLOP) 3.189 2.365 4.612 3.494 2.930
Memory Up to 4GB Up to 3GB 4GB 4GB 4GB/8GB
Memory Rate 2500 MHz 2500 MHz 7.0 (GT/s) 7.0 (GT/s) 2500 MHz
Memory Width 256-bit 192-bit 256-bit 256-bit 256-bit
Architecture Maxwell Maxwell Maxwell Maxwell Kepler
Process Node 28nm 28nm 28nm 28nm 28nm
DirectX Version 12.0 12.0 12.0 12.0 11.0

Just like the desktop models, GTX 980M and GTX 970M are built on the 28nm process technology and are tweaked and built for power efficiency - one of the reasons the mobile release of this product is so interesting.

With a CUDA core count of 1536, the GTX 980M has 33% fewer shader cores than the desktop GTX 980, along with a slightly lower base clock speed. The result is a peak theoretical performance of 3.189 TFLOPs, compared to 4.6 TFLOPs on the GTX 980 desktop. In fact, that is only slightly higher than the GTX 880M based on Kepler, that clocks in with the same CUDA core count (1536) but a TFLOP capability of 2.9. Bear in mind that the GTX 880M is using a different architecture design than the GTX 980M; Maxwell's design advantages go beyond just CUDA core count and clock speed.

The GTX 970M is even smaller, with a CUDA core count of 1280 and peak performance rated at 2.365 TFLOPs. Also notice that the memory bus width has shrunk from 256-bit to 192-bit for this part.

As is typically the case with mobile GPUs, the memory speed of the GTX 980M and GTX 970M is significantly lower than the desktop parts. While the GeForce GTX 980 and 970 that install in your desktop PC will have memory running at 7.0 GHz, the mobile versions will run at 5.0 GHz in order to conserve power.

From a feature set stand point though, the GTX 980M/970M are very much the same as the desktop parts that I looked at in September. You will have support for VXGI, NVIDIA's new custom global illumination technology, Multi-Frame AA and maybe most interestingly, Dynamic Super Resolution (DSR). DSR allows you to render a game at a higher resolution and then use a custom filter to down sample it back to your panel's native resolution. For mobile gamers that are using 1080p screens (as our test sample shipped with) this is a good way to utilize the power of your GPU for less power-hungry games, while getting a surprisingly good image at the same time.

Google Nexus 9 Powered by NVIDIA Tegra K1, Denver 64-bit SoC

Subject: Mobile | October 15, 2014 - 01:10 PM |
Tagged: tegra k1, tegra, nvidia, nexus 9, Nexus, google, Denver

Along with the announcement of the Google Nexus 6 phone, Google is also announcing a new tablet, the Nexus 9. Sporting an 8.9-in IPS screen with a 2048x1536 resolution (4:3 standing strong!), a 6700 mAh battery as well as the new Android Lollipop operating system, perhaps the most interesting specification is that it is built around NVIDIA's Tegra K1 SoC. Specifically, the 64-bit version based on the dual-core custom built Denver design, marking that architectures first release in shipping product.

UPDATE: Amazon.com has the Google Nexus 9 up for pre-order in both 16GB and 32GB capacities!

nexus9-1.jpg

Tegra K1 using 64-bit Denver cores are unique in that it marks the first time NVIDIA has not used off-the-shelf cores from ARM in it's SoC designs. We also know, based on Tim's news post on PC Perspective in August, that the architecture is using a 7-way superscalar design and actually runs a custom instruction set that gets translated to ARMv8 in real-time. 

A software layer and 128MB cache enhance the Dynamic Code Optimization technology by allowing the processor to examine and optimize the ARM code, convert it to the custom instruction set, and further cache the converted microcode of frequently used applications in a cache (which can be bypassed for infrequently processed code). Using the wider execution engine and Dynamic Code Optimization (which is transparent to ARM developers and does not require updated applications), NVIDIA touts the dual Denver core Tegra K1 as being at least as powerful as the quad and octo-core packing competition.

nexus9-3.jpg

It is great news for NVIDIA that Google is using this version of the Tegra K1 (can we please just get a different name for this version of the chip) as it indicates Google's commitment to the architecture in Android going forward, opening doors for the parts integration with even more devices with other hardware vendors moving forward. 

nexus9-2.jpg

More than likely built by HTC, the Nexus 9 will ship in three different colors (black, white and beige) and has a lot of callbacks to the Nexus 7, one of if not THE most popular Android tablet on the market. The tablet has front-facing speakers which should make it good for headphone-free media consumption when necessary. You'll be able put the Nexus 9 into a working mode easily with a new magnetically attached keyboard dock, similar to the iPad accessories widely available.

The Nexus 9 weighs in at 425g (the iPad Air weighs 478g), will have 16GB and 32GB capacity options, going up for preorder on 10/17 and shipping by 11/03. Google will sell both a 32GB Wi-Fi and 32GB LTE model with the LTE version (as well as the Sand color) shipping "later this year." Pricing is set at $399 for the 16GB model, $479 for the 32GB model and $599 for the 32GB+LTE version. That is quite a price hike for LTE capability and the $80 gap between the 16GB and 32GB options is annoying as well.

The GTX 980 can reach very impressive frequencies

Tagged: GTX 980, nvidia, overclocking

[H]ard|OCP has had more time to spend with their reference GTX 980 and have reached the best stable overclock they could on this board without moving to third party coolers or serious voltage mods.  At 1516MHz core and 8GHz VRAM on this reference card, retail models will of course offer different results; regardless it is not too shabby a result.  This overclock was not easy to reach and how they managed it and the lessons they learned along the way make for interesting reading.  The performance increases were noticeable, in most cases the overclocked card was beating the stock card by 25% and as this was a reference card the retail cards with enhanced coolers and the possibility of custom BIOS which disable NVIDIA's TDP/Power Limit settings you could see cards go even faster.  You can bet [H] and PCPer will both be revisting the overclocking potential of GTX 980s.

"The new NVIDIA GeForce GTX 980 makes overclocking GPUs a ton of fun again. Its extremely high clock rates achieved when you turn the right dials and sliders result in real world gaming advantages. We will compare it to a GeForce GTX 780 Ti and Radeon R9 290X; all overclocked head-to-head."

UPDATE: You missed this weeks live stream but you can watch the game play via this YouTube embed!!

I'm sure like the staff at PC Perspective, many of our readers have been obsessively playing the Borderlands games since the first release in 2009. Borderlands 2 arrived in 2012 and once again took hold of the PC gaming mindset. This week marks the release of Borderlands: The Pre-Sequel, which as the name suggests, takes place before the events of Borderlands 2. The Pre-Sequel has playable characters that were previously only known to the gamer as NPCs and that, coupled with the new low-gravity game play style, should entice nearly everyone that loves the first-person, loot-driven series to come back.

To celebrate the release, PC Perspective has partnered with NVIDIA to host a couple of live game streams that will feature some multi-player gaming fun as well some prizes to giveaway to the community. I will be joined by NVIDIA's Andrew Coonrad and Kris Rey to tackle the campaign in a cooperative style while taking a couple of stops to give away some hardware.

SLI Setup and Testing Configuration

The idea of multi-GPU gaming is pretty simple on the surface. By adding another GPU into your gaming PC, the game and the driver are able to divide the workload of the game engine and send half of the work to one GPU and half to another, then combining that work on to your screen in the form of successive frames. This should make the average frame rate much higher, improve smoothness and just basically make the gaming experience better. However, implementation of multi-GPU technologies like NVIDIA SLI and AMD CrossFire are much more difficult than the simply explanation above. We have traveled many steps in this journey and while things have improved in several key areas, there is still plenty of work to be done in others.

As it turns out, support for GPUs beyond two seems to be one of those areas ready for improvement.

IMG_9993.JPG

When the new NVIDIA GeForce GTX 980 launched last month my initial review of the product included performance results for GTX 980 cards running in a 2-Way SLI configuration, by far the most common derivative. As it happens though, another set of reference GeForce GTX 980 cards found there way to our office and of course we needed to explore the world of 3-Way and 4-Way SLI support and performance on the new Maxwell GPU.

The dirty secret for 3-Way and 4-Way SLI (and CrossFire for that matter) is that it just doesn't work as well or as smoothly as 2-Way configurations. Much more work is put into standard SLI setups as those are by far the most common and it doesn't help that optimizing for 3-4 GPUs is more complex. Some games will scale well, others will scale poorly; hell some even scale the other direction.

Let's see what the current state of high GPU count SLI is with the GeForce GTX 980 and whether or not you should consider purchasing more than of these new flagship parts.

Quick Performance Comparison

Earlier this week, we posted a brief story that looked at the performance of Middle-earth: Shadow of Mordor on the latest GPUs from both NVIDIA and AMD. Last week also marked the release of the v1.11 patch for Sniper Elite 3 that introduced an integrated benchmark mode as well as support for AMD Mantle.

I decided that this was worth a quick look with the same line up of graphics cards that we used to test Shadow of Mordor. Let's see how the NVIDIA and AMD battle stacks up here.

For those unfamiliar with the Sniper Elite series, the focuses on the impact of an individual sniper on a particular conflict and Sniper Elite 3 doesn't change up that formula much. If you have ever seen video of a bullet slowly going through a body, allowing you to see the bones/muscle of the particular enemy being killed...you've probably been watching the Sniper Elite games.

screen3.jpg

Gore and such aside, the game is fun and combines sniper action with stealth and puzzles. It's worth a shot if you are the kind of gamer that likes to use the sniper rifles in other FPS titles.

But let's jump straight to performance. You'll notice that in this story we are not using our Frame Rating capture performance metrics. That is a direct result of wanting to compare Mantle to DX11 rendering paths - since we have no way to create an overlay for Mantle, we have resorted to using FRAPs and the integrated benchmark mode in Sniper Elite 3.

Our standard GPU test bed was used with a Core i7-3960X processor, an X79 motherboard, 16GB of DDR3 memory, and the latest drivers for both parties involved. That means we installed Catalyst 14.9 for AMD and 344.16 for NVIDIA. We'll be comparing the GeForce GTX 980 to the Radeon R9 290X, and the GTX 970 to the R9 290. We will also look at SLI/CrossFire scaling at the high end.

MSI Revamps Armory of Gaming Laptops with Latest NVIDIA GTX 970M & 980M Graphics

Subject: Mobile | October 7, 2014 - 01:26 PM |
Tagged: nvidia, msi, maxwell, GTX 980M, GTX 970M, gt dominator, gs stealth, gs ghost

You've heard about NVIDIA's new GTX900M Series and MSI has released two new families of gaming laptops which contain the new GPU.  The GS Stealth and Ghost series are the thinner, lighter more mobile of the laptops while the Dominator Series is more a desktop replacement and should also give you a good workout while you are carting them around.  The base model will run you $1600, with more expensive options available such as the limited edition Crimson Red Stealth Pro model at the end.  Before you ask, no the integral displays are not G-SYNC however since the mobile GPUs are based on Maxwell you may be able to output to a G-SYNC monitor with a variable refresh.  Stay tuned for more.

If there is one message that I get from NVIDIA's GeForce GTX 900M-series announcement, it is that laptop gaming is a first-class citizen in their product stack. Before even mentioning the products, the company provided relative performance differences between high-end desktops and laptops. Most of the rest of the slide deck is showing feature-parity with the desktop GTX 900-series, and a discussion about battery life.

nvidia-maxwell-mobile-logo.jpg

First, the parts. Two products have been announced: The GeForce GTX 980M and the GeForce GTX 970M. Both are based on the 28nm Maxwell architecture. In terms of shading performance, the GTX 980M has a theoretical maximum of 3.189 TFLOPs, and the GTX 970M is calculated at 2.365 TFLOPs (at base clock). On the desktop, this is very close to the GeForce GTX 770 and the GeForce GTX 760 Ti, respectively. This metric is most useful when you're compute bandwidth-bound, at high resolution with complex shaders.

The full specifications are:

  GTX 980M GTX 970M
GTX 980
(Desktop)
GTX 970
(Desktop)
GTX 880M
(Laptop)
CUDA Cores 1536 1280 2048 1664 1536

Perf. (TFLOP) 3.189 2.365 4.612 3.494 2.930
Memory Up to 4GB Up to 3GB 4GB 4GB 4GB/8GB

Architecture Maxwell Maxwell Maxwell Maxwell Kepler
Process Node 28nm 28nm 28nm 28nm 28nm
DirectX Version 12.0 12.0 12.0 12.0 11.0

As for the features, it should be familiar for those paying attention to both desktop 900-series and the laptop 800M-series product launches. From desktop Maxwell, the 900M-series is getting VXGI, Dynamic Super Resolution, and Multi-Frame Sampled AA (MFAA). From the latest generation of Kepler laptops, the new GPUs are getting an updated BatteryBoost technology. From the rest of the GeForce ecosystem, they will also get GeForce Experience, ShadowPlay, and so forth.

For VXGI, DSR, and MFAA, please see Ryan's discussion for the desktop Maxwell launch. Information about these features is basically identical to what was given in September.

nvidia-maxwell-battery.jpg

BatteryBoost, on the other hand, is a bit different. NVIDIA claims that the biggest change is just raw performance and efficiency, giving you more headroom to throttle. Perhaps more interesting though, is that GeForce Experience will allow separate one-click optimizations for both plugged-in and battery use cases.

The power efficiency demonstrated with the Maxwell GPU in Ryan's original GeForce GTX 980 and GTX 970 review is even more beneficial for the notebook market where thermal designs are physically constrained. Longer battery life, as well as thinner and lighter gaming notebooks, will see tremendous advantages using a GPU that can run at near peak performance on the maximum power output of an integrated battery. In NVIDIA's presentation, they mention that while notebooks on AC power can use as much as 230 watts of power, batteries tend to peak around 100 watts. Given that a full speed, desktop-class GTX 980 has a TDP of 165 watts, compared to the 250 watts of a Radeon R9 290X, translates into notebook GPU performance that will more closely mirror its desktop brethren.

nvidia-maxwell-mobile-designs.jpg

Of course, you probably will not buy your own laptop GPU; rather, you will be buying devices which integrate these. There are currently five designs across four manufacturers that are revealed (see image above). Three contain the GeForce GTX 980M, one has a GTX 970M, and the other has a pair of GTX 970Ms. Prices and availability are not yet announced.
