Prelude to Benchmarks:

The details of how the ASUS EAH3870 X2 Top/G/3DHTI/1G/A test system was configured for benchmarking; the specific hardware, software drivers, operating system and benchmark versions are indicated below. All benchmarks for the ASUS EAH3870 X2 Top/G/3DHTI/1G/A were run in Windows Vista Ultimate, the reference videocards were tested in both Windows XP and Vista for the DX10 benchmarks.

PCSTATS is in the process of making the transition to a Windows Vista only test platform, so keep this in mind as you scan the benchmark results. In the second column are the general specs for the reference platforms this Radeon HD ASUS EAH3870 X2 videocard is to be compared against. Please take a moment to look over PCSTATS test system configurations before moving on to the individual benchmark results on the next page.

Benchmark results are grouped by GPU manufacturer first (AMD/ATI or nVidia), then by GPU generation, and then by GPU class (high end, mainstream, value). This approach provides a clearer view of how performance can differ from generation to generation, and class to previous generation. The product being tested is marked with the red colour bar. On with the benchmarks!

An odd driver issue stopped the single ASUS EAH3870 X2 from completing the 3DMark Vantage suite, but the Crossfire version put up numbers comparable with the Palit 4870 X2 2GB.

Crysis is a science fiction first-person shooter developed by Crytek. Crysis uses Microsoft's new API, DirectX 10 for graphics rendering, and includes the new engine—the CryEngine 2—that is the successor to Far Cry's CryEngine. CryEngine 2 is among the first engines to use the DirectX 10 framework of Windows Vista, but can also run using DirectX 9, both on Vista and Windows XP.

Crysis seems to be getting bottlenecked at lower resolutions, but as the resolution is scaled upwards the ASUS EAH3870 X2 finally shows some benefit from being run in Crossfire mode - although not quite enough of a performance gain to justify buying two cards. The single ASUS EAH3870 X2 manages to best the Radeon HD 4850, despite the latter's newer core architecture.
