SLI Testing

Let's see if I can start this story without sounding too much like a broken record when compared to the news post I wrote late last week on the subject of NVIDIA's new 337.50 driver. In March, while attending the Game Developer's Conference to learn about the upcoming DirectX 12 API, I sat down with NVIDIA to talk about changes coming to its graphics driver that would affect current users with shipping DX9, DX10 and DX11 games. 

As I wrote then:

What NVIDIA did want to focus on with us was the significant improvements that have been made on the efficiency and performance of DirectX 11.  When NVIDIA is questioned as to why they didn’t create their Mantle-like API if Microsoft was dragging its feet, they point to the vast improvements possible and made with existing APIs like DX11 and OpenGL. The idea is that rather than spend resources on creating a completely new API that needs to be integrated in a totally unique engine port (see Frostbite, CryEngine, etc.) NVIDIA has instead improved the performance, scaling, and predictability of DirectX 11.

NVIDIA claims that these fixes are not game specific and will improve performance and efficiency for a lot of GeForce users. Even if that is the case, we will only really see these improvements surface in titles that have addressable CPU limits or very low end hardware, similar to how Mantle works today.

In truth, this is something that both NVIDIA and AMD have likely been doing all along but NVIDIA has renewed purpose with the pressure that AMD's Mantle has placed on them, at least from a marketing and PR point of view. It turns out that the driver that starts to implement all of these efficiency changes is the recent 337.50 release and on Friday I wrote up a short story that tested a particularly good example of the performance changes, Total War: Rome II, with a promise to follow up this week with additional hardware and games. (As it turns out, results from Rome II are...an interesting story. More on that on the next page.)

Today I will be looking at seemingly random collection of gaming titles, running on some reconfigured test bed we had in the office in an attempt to get some idea of the overall robustness of the 337.50 driver and its advantages over the 335.23 release that came before it. Does NVIDIA have solid ground to stand on when it comes to the capabilities of current APIs over what AMD is offering today?

NVIDIA GeForce Driver 337.50 Early Results are Impressive

Subject: Graphics Cards | April 11, 2014 - 03:30 PM |
Tagged: nvidia, geforce, dx11, driver, 337.50

UPDATE: We have put together a much more comprehensive story based on the NVIDIA 337.50 driver that includes more cards and more games while also disputing the Total War: Rome II results seen here. Be sure to read it!!

When I spoke with NVIDIA after the announcement of DirectX 12 at GDC this past March, a lot of the discussion centered around a pending driver release that promised impressive performance advances with current DX11 hardware and DX11 games. 

What NVIDIA did want to focus on with us was the significant improvements that have been made on the efficiency and performance of DirectX 11.  When NVIDIA is questioned as to why they didn’t create their Mantle-like API if Microsoft was dragging its feet, they point to the vast improvements possible and made with existing APIs like DX11 and OpenGL. The idea is that rather than spend resources on creating a completely new API that needs to be integrated in a totally unique engine port (see Frostbite, CryEngine, etc.) NVIDIA has instead improved the performance, scaling, and predictability of DirectX 11.

NVIDIA claims that these fixes are not game specific and will improve performance and efficiency for a lot of GeForce users. Even if that is the case, we will only really see these improvements surface in titles that have addressable CPU limits or very low end hardware, similar to how Mantle works today.

Lofty goals to be sure. This driver was released last week and I immediately wanted to test and verify many of these claims. However, a certain other graphics project kept me occupied most of the week and then a short jaunt to Dallas kept me from the task until yesterday. 

To be clear, I am planning to look at several more games and card configurations next week, but I thought it was worth sharing our first set of results. The test bed in use is the same as our standard GPU reviews.

Test System Setup
CPU Intel Core i7-3960X Sandy Bridge-E
Motherboard ASUS P9X79 Deluxe
Memory Corsair Dominator DDR3-1600 16GB
Hard Drive OCZ Agility 4 256GB SSD
Sound Card On-board
Graphics Card NVIDIA GeForce GTX 780 Ti 3GB
NVIDIA GeForce GTX 770 2GB
Graphics Drivers NVIDIA: 335.23 WHQL, 337.50 Beta
Power Supply Corsair AX1200i
Operating System Windows 8 Pro x64

The most interesting claims from NVIDIA were spikes as high as 70%+ in Total War: Rome II, so I decided to start there. 

First up, let's take a look at the GTX 780 Ti SLI results, the flagship gaming card from NVIDIA.

TWRome2_2560x1440_OFPS.png

TWRome2_2560x1440_PER.png

TWRome2_2560x1440_PLOT.png

With this title, running at the Extreme preset, jumps from an average frame rate of 59 FPS to 88 FPS, an increase of 48%! Frame rate variance does increase a bit with the faster average frame rate but it stays within limits of smoothness, but barely.

Next up, the GeForce GTX 770 SLI results.

TWRome2_2560x1440_OFPS.png

TWRome2_2560x1440_PER.png

TWRome2_2560x1440_PLOT.png

Results here are even more impressive as the pair of GeForce GTX 770 cards running in SLI jump from 29.5 average FPS to 51 FPS, an increase of 72%!! Even better, this occurs without any kind of frame rate variance increase and in fact, the blue line of the 337.50 driver is actually performing better in that perspective.

All of these tests were run with the latest patch on Total War: Rome II and I did specifically ask NVIDIA if there were any differences in the SLI profiles between these two drivers for this game. I was told absolutely not - this just happens to be the poster child example of changes NVIDIA has made with this DX11 efficiency push.

Of course, not all games are going to see performance improvements like this, or even improvements that are measurable at all. Just as we have seen with other driver enhancements over the years, different hardware configurations, image quality settings and even scenes used to test each game will shift the deltas considerably. I can tell you already that based on some results I have (but am holding for my story next week) performance improvements in other games are ranging from <5% up to 35%+. While those aren't reaching the 72% level we saw in Total War: Rome II above, these kinds of experience changes with driver updates are impressive to see.

Even though we are likely looking at the "best case" for NVIDIA's 337.50 driver changes with the Rome II results here, clearly there is merit behind what the company is pushing. We'll have more results next week!

Some NVIDIA R337.50 Driver Controversy

Subject: General Tech, Graphics Cards | April 8, 2014 - 06:44 PM |
Tagged: nvidia, geforce, drivers

NVIDIA's GeForce 337.50 Driver was said to address performance when running DirectX 11-based software. Now that it is out, multiple sources are claiming the vendor-supplied benchmarks are exaggerated or simply untrue.

nvidia-337-sli.png

ExtremeTech compiled benchmarks from Anandtech and BlackHoleTec.

Going alphabetically, Anandtech tested the R337.50 and R331.xx drivers with a GeForce GTX 780 Ti, finding a double-digit increase with BioShock: Infinite and Metro: Last Light and basically zero improvement for GRID 2, Rome II, Crysis: Warhead, Crysis 3, and Company of Heroes 2. Adding a second GTX 780 Ti into the mix helped matters, seeing a 76% increase in Rome II and about 9% in most of the other titles.

BlackHoleTec is next. Testing the mid-range, but overclocked GeForce 760 between R337.50 and R335.23 drivers, they found slight improvements (1-3 FPS), except for Battlefield 4 and Skyrim (the latter is not DX11 to be fair) which noticed a slight reduction in performance (about 1 FPS).

ExtremeTech, finally, published one benchmark but it did not compare between drivers. All it really shows is CPU scaling in AMD GPUs.

Unfortunately, I do not have any benchmarks to present of my own because I am not a GPU reviewer nor do I have a GPU testbed. Ironically, the launch of the Radeon R9 295 X2 video card might have lessened that number of benchmarks available for NVIDIA's driver, who knows?

If it is true, and R337.50 does basically nothing in a setup with one GPU, I am not exactly sure what NVIDIA was hoping to accomplish. Of course someone was going to test it and publish their results. The point of the driver update was apparently to show how having a close relationship with Microsoft can lead you to better PC gaming products now and in the future. That can really only be the story if you have something to show. Now, at least I expect, we will probably see more positive commentary about Mantle - at least when people are not talking about DirectX 12.

If you own a GeForce card, I would still install the new driver though, especially if you have an SLi configuration. Scaling to a second GPU does see measurable improvements with Release 337.50. Even for a single-card configuration, it certainly should not hurt anything.

NAB 2014: Intel Iris Pro Support in Adobe Creative Cloud (CC)

When Adobe started to GPU-accelerate their applications beyond OpenGL, it started with NVIDIA and its CUDA platform. After some period of time, they started to integrate OpenCL support and bring AMD into the fold. At first, it was limited to a couple of Apple laptops but has since expanded to include several GPUs on both OSX and Windows. Since then, Adobe switched to a subscription-based release system and has published updates on a more rapid schedule. The next update of Adobe Premiere Pro CC will bring OpenCL to Intel Iris Pro iGPUs.

Intel-IrisPro-Adobe-Masking.jpg

Of course, they specifically mentioned Adobe Premiere Pro CC which suggests that Photoshop CC users might be coming later. The press release does suggest that the update will affect both Mac and Windows versions of Adobe Premiere Pro CC, however, so at least platforms will not be divided. Well, that is, if you find a Windows machine with Iris Pro graphics. They do exist...

A release date has not been announced for this software upgrade.

A Powerful Architecture

AMD likes to toot its own horn. Just a take a look at the not-so-subtle marketing buildup to the Radeon R9 295X2 dual-Hawaii graphics card, released today. I had photos of me shipped to…me…overnight. My hotel room at GDC was also given a package which included a pair of small Pringles cans (chips) and a bottle of volcanic water. You may have also seen some photos posted of a mysterious briefcase with its side stickered by with the silhouette of a Radeon add-in board.

This tooting is not without some validity though. The Radeon R9 295X2 is easily the fastest graphics card we have ever tested and that says a lot based on the last 24 months of hardware releases. It’s big, it comes with an integrated water cooler, and it requires some pretty damn specific power supply specifications. But AMD did not compromise on the R9 295X2 and, for that, I am sure that many enthusiasts will be elated. Get your wallets ready, though, this puppy will run you $1499.

Both AMD and NVIDIA have a history of producing high quality dual-GPU graphics cards late in the product life cycle. The most recent entry from AMD was the Radeon HD 7990, a pair of Tahiti GPUs on a single PCB with a triple fan cooler. While a solid performing card, the product was released in a time when AMD CrossFire technology was well behind the curve and, as a result, real-world performance suffered considerably. By the time the drivers and ecosystem were fixed, the HD 7990 was more or less on the way out. It was also notorious for some intermittent, but severe, overheating issues, documented by Tom’s Hardware in one of the most harshly titled articles I’ve ever read. (Hey, Game of Thrones started again this week!)

The Hawaii GPU, first revealed back in September and selling today under the guise of the R9 290X and R9 290 products, is even more power hungry than Tahiti. Many in the industry doubted that AMD would ever release a dual-GPU product based on Hawaii as the power and thermal requirements would be just too high. AMD has worked around many of these issues with a custom water cooler and placing specific power supply requirements on buyers. Still, all without compromising on performance. This is the real McCoy.

NVIDIA 337.50 Driver and GeForce Experience 2.0 Released

Subject: General Tech, Graphics Cards | April 7, 2014 - 09:01 AM |
Tagged: nvidia, geforce experience, directx 11

We knew that NVIDIA had an impending driver update providing DirectX 11 performance improvements. Launched today, 337.50 still claims significant performance increases over the previous 335.23 version. What was a surprise is GeForce Experience 2.0. This version allows both ShadowPlay and GameStream to operate on notebooks. It also allows ShadowPlay to record, and apparently stream to Twitch, your Windows desktop (but not on notebooks). It also enables Battery Boost, discussed previously.

nvidia-shadowplay-desktop.png

Personally, I find desktop streaming is the headlining feature, although I rarely use laptops (and much less for gaming). This is especially useful for OpenGL, games which run in windowed mode, and if you want to occasionally screencast without paying for Camtasia or tinkering with CamStudio. If I were to make a critique, and of course I will, I would like the option to select which monitor gets recorded. Its current behavior records the primary monitor as far as I can tell.

I should also mention that, in my testing, "shadow recording" is not supported when not recording a fullscreen game. I'm guessing that NVIDIA believes their users would prefer to not record their desktops until manually started and likewise stopped. It seems like it had to have been a conscious decision. It does limit its usefulness in OpenGL or windowed games, however.

This driver also introduces GameStream for devices out of your home discussed in the SHIELD update.

nvidia-337-sli.png

This slide is SLi improvements, driver-to driver, for the GTX 770 and the 780 Ti.

As for the performance boost, NVIDIA claims up to 64% faster performance in configurations with one active GPU and up to 71% faster in SLI. It will obviously vary on a game-by-game and GPU-by-GPU basis. I do not have any benchmarks, besides a few examples provided by NVIDIA, to share. That said, it is a free driver. If you have a GeForce GPU, download it. It does complicate matters if you are deciding between AMD and NVIDIA, however.
