Battlefield 2 Performance

This benchmark is performed using DICE's built in demo playback functionality with a few added extras built in house. When using the built in demo playback features of BF2, frames rendered during the loading screen are counted in the benchmark. In order to get a real idea of performance, we use the instantaneous frametime and frames per second data generated from a benchmark run. We discard the data collected during the loading screen and calculate a result that represents the actual gameplay that was benchmarked. While DICE maintains that results over 100fps aren't reliable, our methods have allowed us to get useful data from high performing systems.

During the benchmark, the camera switches between players and vehicles in order to capture the most action possible. There is a lot of smoke and explosions, so this is a very GPU intensive Battlefield 2 benchmark. The game itself is best experienced with average in-game framerates of 35 and up.

We ran Battlefield 2 using the highest quality graphics settings we could. Shadows, lighting, and especially view distance are very important in order to best play the game. In our opinion view distance should never be set to less than the max, but other settings can be decreased slightly if a little more performance or a higher resolution is required.

Its ability to offer 7900 GT levels of performance at the price of a 7900 GS makes the Radeon X1950 Pro quite a deal. The added memory speed gives the X1950 Pro a good advantage over the X1900 GT here. Of course, when the new handicapped X1900 GT comes along, expect this gap to widen. X1950 Pro CrossFire offers performance levels on par with X1900/X1950 XTX under BF2 without AA enabled. This puts it in competition with the 7900 GTX and offers much better performance than the 7950 GT. All what we would expect from $400 of graphics card. Interestingly, NVIDIA's 7900 GS SLI is able to offer better performance than X1950 Pro CrossFire in spite of the single card performance advantage the later maintains. This indicates that SLI scales much better than CrossFire under these conditions.

With 4xAA enabled, the X1950 Pro performs even better compared to the competition. CrossFire, however, doesn't give any more of a boost in comparison to X1900/X1950 XTX or 7900 GS SLI than we saw without AA. The X1950 Pro is an excellent choice as a single card solution, but for multi-GPU users, SLI is still a better bet.

Much appreciated by MadBadger, 1211 days ago
Thanks for the review :beer;

An observation:

-the pricefinder at the top of the article seems a bit out of whack. It shows as x1950 512 mb (PCI), but it links to the 1950 pro 256 mb for amazon and to the x1950 xt for the others.

Bit disappointed, was hoping for 600/700 clocks. I'm curious about the temperatures under load and if it would easily overclock to at least those speeds. And what about HDCP? But I guess we'll have to wait for retail cards.

If the price is €200 or less I just might be getting one to replace my x800xt :)

Apparantly, powercolor clocks all its x1950pro cards up to 600/700 and have a 512mb sku. Plus silent cooling :)

No word on hdcp and price tho :/

Go read the review over at bit-tech. They've got prices up and the Saphire card they reviewed has HDCP.

HDCP support is optional for vendors, but it seems like ATI is heavily encouraging them to include HDCP on all 1950 PRO cards. Since it's not guaranteed, be sure to check the specifications before you purchase.

The power color 1950 PRO is not passively cooled but it includes a low dB fan. It does look like an interesting product, and we intend to acquire one for further investigation.

Intel D975XBX by Rza79, 1211 days ago
The Tech Report had problems with this motherboard and Crossfire which made them switch to the Asus P5W DH.
You aren't expiriencing any problems with this board?

Second thing, why no AA with games like B&W2 and FEAR?

No problems with the motherboard.

AA performance under Black and White 2 and FEAR were excluded because we decided framerate was already at a minimum for the resolution we were testing.

Why is this CF implementation worse than SLI? by Goty, 1211 days ago
You guys are ragging on this CF implementation like it's some sub-par solution. The transfer speed may be lower than that used by NVIDIA's SLI bridge, but SLI is simplex while this implementation is full duplex. Being able to send data in both directions at the same time should provide a huge speed boost while using ATi's SuperAA modes.

RE: Why is this CF implementation worse than SLI? by JarredWalton, 1211 days ago
Scalability is the key factory. In most benchmarks, SLI gets more of an improvement than CrossFire, indicating that the compositing engine is not an optimal multi-GPU solution. There's almost certainly a decent amount of overhead involved. We do like the new CF connector, but the proof is in the pudding. If 7900 GS is clearly slower in single card configs but often faster in dual-GPU configs, clearly SLI is scaling better than CF.

RE: Why is this CF implementation worse than SLI? by Goty, 1210 days ago
Are you guys thinking of doing any testing with any of either vendor's multi-card AA modes any time soon? I really think the full duplex connection would really help there (i.e. the cards may not scale as well with the number of cards, but what about as the image quality increases?)
