What, me jealous? Four weeks with SLI'd GTX 980s

Just in case you need a reason to be insanely jealous of someone, [H]ard|OCP has just published an article covering what it is like to be living with two GTX 980's in SLI.  The cards are driving three Dell U2410 24" 1920x1200 displays for a relatively odd resolution of 3600x1920 but apart from an issue with the GeForce Experience software suite the cards have no trouble displaying to all three monitors.  In their testing of Borderlands games they definitely noticed when PhysX was turned on, though like others [H] wishes that PhysX would abandon its proprietary roots.  When compared to the Radeon R9 290X CrossFire system the performance is very similar but when you look at heat, power and noise produced the 980's are the clear winner.  Keep in mind a good 290X is just over $300 while the least expensive GTX 980 will run you over $550.

"What do you get when you take two NVIDIA GeForce GTX 980 video cards, configure those for SLI, and set those at your feet for four weeks? We give our thoughts and opinions about actually using these GPUs in our own system for four weeks with focus on performance, sound profile, and heat generated by these cards."

Mini-ITX Sized Package with a Full Sized GPU

PC components seem to be getting smaller.  Micro-ATX used to not be very popular for the mainstream enthusiast, but that has changed as of late.  Mini-ITX is now the hot form factor these days with plenty of integrated features on motherboards and interesting case designs to house them in.  Enthusiast graphics cards tend to be big, and that is a problem for some of these small cases.  Manufacturers are responding to this by squeezing every ounce of cooling performance into smaller cards that more adequately fit in these small chassis.

msi760_01.jpg

MSI is currently offering their midrange cards in these mini-ITX liveries.  The card we have today is the GTX 760 Mini-ITX Gaming.  The GTX 760 is a fairly popular card due to it being fairly quick, but not too expensive.  It is still based on the GK104, though fairly heavily cut down from a fully functional die.  The GTX 760 features 1152 CUDA Cores divided into 6 SMXs.  A fully functional GK104 is 1536 CUDA Cores and 8 SMXs.  The stock clock on the GTX 760 is 980 MHz with a boost up to 1033 MHz.

The pricing for the GTX 760 cards is actually fairly high as compared to similarly performing products from AMD.  NVIDIA feels that they offer a very solid product at that price and do not need to compete directly with AMD on a performance per dollar basis.  Considering that NVIDIA has stayed very steady in terms of marketshare, they probably have a valid point.  Overall the GTX 760 performs in the same general area as a R9 270X and R9 280, but again the AMD parts have a significant advantage in terms of price.

The challenges for making a high performing, small form factor card are focused on power delivery and thermal dissipation.  Can the smaller PCB still have enough space for all of the VRMs required with such a design?  Can the manufacturer develop a cooling solution that will keep the GPU in the designed thermal envelope?  MSI has taken a shot at these issues with their GTX 760 Mini-ITX OC edition card.

A Civ for a New Generation

Turn-based strategy games have long been defined by the Civilization series. Civ 5 took up hours and hours of the PC Perspective team's non-working hours (and likely the working ones too) and it looks like the new Civilization: Beyond Earth has the chance to do the same. Early reviews of the game from Gamespot, IGN, and Polygon are quite positive, and that's great news for a PC-only release; they can sometimes get overlooked in the games' media.

For us, the game offers an interesting opportunity to discuss performance. Beyond Earth is definitely going to be more CPU-bound than the other games that we tend to use in our benchmark suite, but the fact that this game is new, shiny, and even has a Mantle implementation (AMD's custom API) makes interesting for at least a look at the current state of performance. Both NVIDIA and AMD sent have released drivers with specific optimization for Beyond Earth as well. This game is likely to be popular and it deserves the attention it gets.

Testing Process

Civilization: Beyond Earth, a turn-based strategy game that can take a very long time to complete, ships with an integrated benchmark mode to help users and the industry test performance under different settings and hardware configurations. To enable it, you simple add "-benchmark results.csv" to the Steam game launch options and then start up the game normally. Rather than taking you to the main menu, you'll be transported into a view of a map that represents a somewhat typical gaming state for a long term session. The game will use the last settings you ran the game at to measure your system's performance, without the modified launch options, so be sure to configure that before you prepare to benchmark.

The output of this is the "result.csv" file, saved to your Steam game install root folder. In there, you'll find a list of numbers, separated by commas, representing the frame times for each frame rendering during the run. You don't get averages, a minimum, or a maximum without doing a little work. Fire up Excel or Google Docs and remember the formula:

1000 / Average (All Frame Times) = Avg FPS

It's a crude measurement that doesn't take into account any errors, spikes, or other interesting statistical data, but at least you'll have something to compare with your friends.

Our testing settings

Just as I have done in recent weeks with Shadow of Mordor and Sniper Elite 3, I ran some graphics cards through the testing process with Civilization: Beyond Earth. These include the GeForce GTX 980 and Radeon R9 290X only, along with SLI and CrossFire configurations. The R9 290X was run in both DX11 and Mantle.

  • Core i7-3960X
  • ASUS Rampage IV Extreme X79
  • 16GB DDR3-1600
  • GeForce GTX 980 Reference (344.48)
  • ASUS R9 290X DirectCU II (14.9.2 Beta)

Mantle Additions and Improvements

AMD is proud of this release as it introduces a few interesting things alongside the inclusion of the Mantle API.

  1. Enhanced-quality Anti-Aliasing (EQAA): Improves anti-aliasing quality by doubling the coverage samples (vs. MSAA) at each AA level. This is automatically enabled for AMD users when AA is enabled in the game.
     
  2. Multi-threaded command buffering: Utilizing Mantle allows a game developer to queue a much wider flow of information between the graphics card and the CPU. This communication channel is especially good for multi-core CPUs, which have historically gone underutilized in higher-level APIs. You’ll see in your testing that Mantle makes a notable difference in smoothness and performance high-draw-call late game testing.
     
  3. Split-frame rendering: Mantle empowers a game developer with total control of multi-GPU systems. That “total control” allows them to design an mGPU renderer that best matches the design of their game. In the case of Civilization: Beyond Earth, Firaxis has selected a split-frame rendering (SFR) subsystem. SFR eliminates the latency penalties typically encountered by AFR configurations.

EQAA is an interesting feature as it improves on the quality of MSAA (somewhat) by doubling the coverage sample count while maintaining the same color sample count as MSAA. So 4xEQAA will have 4 color samples and 8 coverage samples while 4xMSAA would have 4 of each. Interestingly, Firaxis has decided the EQAA will be enabled on Beyond Earth anytime a Radeon card is detected (running in Mantle or DX11) and AA is enabled at all. So even though in the menus you might see 4xMSAA enabled, you are actually running at 4xEQAA. For NVIDIA users, 4xMSAA means 4xMSAA. Performance differences should be negligible though, according to AMD (who would actually be "hurt" by this decision if it brought down FPS).

UPDATE: It's time for ROUND 2!

UPDATE 2: You missed the fun for the second time? That's unfortunate, but you can relive the fun with the replay right here!

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 once again 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.

Gigabyte Packs Factory Overclocked GTX 970 GPU Into Mini ITX Card

Subject: Graphics Cards | October 21, 2014 - 06:42 PM |
Tagged: maxwell, nvidia, gaming, mini ITX, small form factor, GTX 970, GM204, gigabyte

Gigabyte has announced a new miniature graphics card based around NVIDIA's GeForce GTX 970 GPU. The upcoming card is a dual slot, single fan design that is even shorter than the existing GTX 970 graphics cards (which are fairly short themselves). Officially known as the GV-N970IXOC-4GD, the miniaturized GTX 970 will be available for your small form factor (Mini ITX) systems in November for around $330.

The new Mini ITX compatible graphics card packs in a factory overclocked GeForce GTX 970 processor, 4GB of video memory, a custom PCB, and a custom WindForce-inspired cooler into a graphics card that is smaller than any of the existing GTX 970 cards. Gigabyte is using a custom design with a single 8-pin PCI-E power connector instead of two 6-pin connectors from the reference design or the 6-pin plus 8-pin from manufacturers like EVGA. The single power connector means less cabling to route (and successfully attempt to hide heh) and better small form factor PSU compatibility. The cooler is an aluminum fin array with three copper heatpipes paired with a single shrouded fan.

The tiny card comes factory overclocked at 1076 MHz base and 1216 MHz boost, which is a respectable boost over the reference specifications. For reference, the GeForce GTX 970 processor is a 28nm chip using NVIDIA's GM204 "Maxwell" architecture with 1664 CUDA cores clocked at 1051 MHz base and 1178 MHz boost. It appears that Gigabyte has left the 4GB of GDDR5 untouched at 7.0 GT/s.

  Gigabyte GTX 970 Mini ITX

CUDA Cores 1664 1664
Core (MHz) 1076 1051
Core (MHz) Boost 1216 1178
Memory 4GB 4GB
Memory Rate 7.0 (GT/s) 7.0 (GT/s)
Memory Width 256-bit 256-bit
Architecture Maxwell Maxwell
Process Node 28nm 28nm
PCI-E Power 1x 8-pin 2x 6-pin
DirectX Version 12.0 12.0

The display output on the miniature Gigabyte card differs slightly from the reference design with the addition of a DVI-D connection.

  • 3 x DisplayPort
  • 1 x HDMI
  • 1 x DVI-I
  • 1 x DVI-D

According to Gigabyte, its custom cooler resulted in lower temperatures versus the reference design. The company claims that when running Metro: Last Light, the Mini ITX Gigabyte GTX 970 GPU ran at 62°C versus a reference design hitting 76°C running the same game. If true, the Gigabyte cooler is capable of keeping the card significantly cooler while taking up less space (though fan speeds and sound levels were not mentioned, nor compared to other custom coolers).

The small form factor friendly GTX 970 is coming next month with a MSRP of $329.99. Are you excited?

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

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.

notebook1.jpg

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.
