High End GPU Performance

While a few titles based on the Unreal Engine 3 have already made their way onto the scene, the detail and atmosphere of Unreal Tournament 3 really show off what developers can do with this engine if they take the time to understand it. Between its first party titles and Bioshock, Epic certainly makes a solid statement that its Unreal Engine 3 is an excellent choice for leading edge graphics.

For this test, we are looking at performance scaling on high end video cards ($300+) across multiple resolutions and on multiple maps. We will absolutely be revisiting this game with midrange hardware and multiGPU configurations. In this analysis, we focus on the performance of the Suspense capture the flag map flyby. This is the most graphically intense flyby we have, and the other two maps we tested tended to exhibit similar relative performance between cards.

With our high end hardware, we've pulled out the 1920 x 1200 tests, as this is very likely to be the resolution paired with one of these parts.

Unreal Tournament 3 Demo Performance
 

The NVIDIA GeForce 8800 GTX and Ultra both outperform the AMD Radeon HD 2900 XT, which is to be expected: the 2900 XT costs much less. But the performance gap here is not huge, and the 2900 XT gets major points for that. It handily outperforms its direct competition, the 8800 GTS (both 640MB and 320MB perform nearly identically). Not surprisingly, the X1950 XTX bests the 7900 GTX, and both of these parts perform worse than the 8800 GTS cards.

If we look at the scaling graph for Suspense, we can see that the GTS cards remain above 40fps even at 2560x1600. This is quite impressive, especially for the low memory GTS, but we do have to keep in mind that this is a flyby in a demo version of the game and we may see changes in performance between now and the final version.

Also intriguing is the fact that the high end NVIDIA hardware seems to become CPU limited at less than 1600x1200. This leads to the fact that AMD's Radeon HD 2900 XT actually outperforms the 8800 Ultra at 1280x1024. The 8800 Ultra does seem to scale very well with resolution, while the 7900 GTX drops off quickly and under performs through out the test.

While the rest of this data is very similar to what we've already presented, we did go to the trouble of running the numbers. In order to present a complete picture of what we've seen on the less demanding levels, here is the rest of our data:

Final Words

We're just getting started with our UT3 performance analysis, but already there are some interesting conclusions to be had. Quite possibly the biggest takeaway from this comparison is the dramatic improvement in multi-threaded game development over the past couple of years. Starting from a point where none of our game benchmarks were multi-threaded just two years ago, here we are today with the latest and greatest from Epic, and seeing huge gains from one to two cores, and promising improvements when moving to four cores.

Quad-core gaming is still years away from being relevant (much less a requirement), but the industry has come a tremendous distance in an honestly very short period of time. We're more likely to have multi-threaded games these days than 64-bit versions of those titles, mostly thanks to the multi-core architecture in both the Xbox 360 and PlayStation 3. Like it or not, but much of PC gaming development is being driven by consoles, the numbers are simply higher on that side of the fence (even though the games themselves look better on this side).

On the GPU side, NVIDIA of course does quite well with the 8800 lineup, but the real surprise is how competitive AMD is with the Radeon HD 2900 XT. There may be some salvage yet for that architecture, if AMD could only bring out a midrange part that actually offered compelling performance...

    See the post right above yours. ;-)

    Isn't this game supposed to use the Ageia crap to improve performance? Would love to see some benchies on that.
  • Ryan Smith - Wednesday, October 17, 2007 - link

    Yes, it can use the PhysX hardware to improve performance. However flybys are completely useless for testing PhysX, because there is no physics work going on. Since I cover the PPU side of things, once we have the ability to play with demos we'll have an article up.

    Great work showing all the different gradients on vid card, cache, cpu, threading.
    The game really scales impressively on hardware.
    How did Sweeney manage to make the 2900xt shine? hehe

    I've got some small reservations using the flyby's, hopefully you guys will have a demo run for next time around. Theoretically, a demo loop should be pretty similar, mainly more CPU intensive, but I'm curious to see.

    Good work showing off the games scaling.

    Not only does the X1950XT absolutely destroy the 7900GTX (the ATI card REALLY ended up being the better long-term buy), but the HD 2900XT looks absolutely great here. If this sort of performance is indicative of the future (and it may not be - perhaps there is something that will favor nVidia when the release copy of the game arrives with better graphics) then ATI looks much better than it did even last month.

    PLEASE do a follow up with this game at launch/when the new midrange GPUs launch. It's going to be very interesting to see the price/performance between the new 8800GT, an overclocked HD 2900pro, and the new ATI midrange card (HD 2950pro?)

    they used an X1950XTX, though it would be about the same
    they should have used the XT because it can still be found, and for a decent price

    Anand,
    the last 2 game reviews are nice to have 1024x768 CPU comparisons, but I think we're seeing too many pages of 1024x768 of that which probably only 2% of the guys planning on running these games will use.

    I'd rather suggest showing at least the scaling if there's an intention of showing CPU limitations to the common 1280x1024, the 1680x1050(1600x1200) and the 1920x1200 to reflect what we're also actually are going to see on screen as user by swapping/Upgrading a CPU/Platform to another model/platform while planning on playing with our obviously high end GFX card at 1920x1200.

    an Overall CPU comparison with at only 1024x768 left me severely disappointed though I can understand the time constraints. This regrettably reminds me at Toms with their beside-the-point tactics in articles.

    Just my .02 for making Anands a bit better.

    I'd really like to see 1280x720. I usually play on my 720p TV and I imagine that resolution would be CPU-bound as well, though probably less so than 1024x768.
  • Roy2001 - Wednesday, October 17, 2007 - link

    I am more interest to see Phenom data.

    I'm officially done with Anandtech's conclusions on benchmarks. Why are you making these blanket "AMD is not competitive" statements? A 9% difference in fps performance and now AMD is shit?! Not to mention that whopping 9% difference only works out to roughly 5 whole frames per second! ROFLMAO!!!!!

    Brad: Hey Johnny! Did you see the new UT3 review from Anandtech? They showed the Intel CPU's KILLING AMD by five frames per second!

    Johnny: Holy shit Brad!!!!! AMD is going out of business with piss poor performance like that. I'll NEVER buy AMD again.
