Performance tests
Testbed:
- Intel Core i7-975 3340 MHz CPU
- ASUS P6T Deluxe motherboard on the Intel X58 chipset
- 6GB of 1600MHz DDR3 SDRAM from Corsair
- WD Caviar SE WD1600JD 160GB SATA HDD
- Tagan TG900-BZ 900W PSU
- Windows 7 Ultimate 64-bit, DirectX 11
- 30" Dell 3007WFP monitor
- VSync disabled
- NVIDIA Drivers 266.58
- ATI CATALYST 11.1
Benchmarks:
- Far Cry 2 (Ubisoft) — DirectX 10.0, Shaders 4.0 (HDR), built-in benchmarking utility (the Middle level), maximum settings.
- CRYSIS Warhead (Crytek/EA) — Cargo, DirectX 10.0, Shaders 4.0, Very High settings, batch file, timedemo available by e-mail request.
- Colin McRae: DiRT 2 (Codemasters) — DirectX 10.0/11.0, Ultra High settings, run as follows: "dirt2.exe -benchmark example_benchmark.xml".
- Metro 2033 (4A Games/THQ) — DirectX 11.0, Super High settings, PhysX disabled, run from in game.
- Just Cause 2 (Avalanche Studios/Eidos Interactive) — DirectX 11.0, Super High settings, run from in game.
- Aliens vs. Predator (Rebellion/SEGA) — DirectX 11.0, Shaders 5.0, Very High settings, run from in game.
- F1 2010 (Codemasters) — DirectX 11.0, Ultra High settings, run as follows: "formulaone.exe -benchmark example_benchmark.xml". Game provided by NVIDIA.
- Tropics Benchmark 1.3 (Unigine) — DirectX 10.0, High settings.
- Heaven Benchmark 2.0 (Unigine) — DirectX 11.0, High settings.
- 3DMark 11 (FutureMark) — DirectX 11.0, Performance settings.
We'd like to thank Unigine for helping us set up their benchmarks.
Please note that there's a misprint in the diagrams: "GTX 570 1280MB 800/1600/4000 MHz" should actually be "GTX 570 1280MB 825/1650/4400 MHz."
The factory overclocking from 900 MHz to 940 MHz boosts the performance of PowerColor PCS+ HD6870 1GB GDDR5 by just 4-5%, so there's no sense in adding another item to the diagrams. You can easily guess that it's just a bit faster.

Conclusions
PowerColor HD6850 1GB GDDR5 is a very nice solution in terms of both price/performance ratio (it's in the top ten) and cooler efficiency.
PowerColor PCS+ HD6870 1GB GDDR5 is not as nice but still very decent, and the cooler is quite efficient, too.
We express gratitude to PowerColor for the provided graphics cards. The PSU is provided by TAGAN, the monitor is provided by NVIDIA.
