Dirt 2 and Battleforge (both DX11 titles) benchmarks have been leaked at
PCOnline Forums (originating from PCZilla BBS), comparing the upcoming
Radeon HD 6850/6870 cards to their likely competitors – the GTX 460.
Both titles were previously believed to favour the Nvidia cards, thanks
to its stronger tessellation performance. However, it is clear that AMD
have improved DX11 performance, as the HD 6800 cards end up well ahead
of both GTX 460s.

Dirt 2 and Battleforge (both DX11 titles) benchmarks have been leaked at PCOnline Forums (originating from PCZilla BBS), comparing the upcoming Radeon HD 6850/6870 cards to their likely competitors – the GTX 460. Both titles were previously believed to favour the Nvidia cards, thanks to its stronger tessellation performance. However, it is clear that AMD have improved DX11 performance, as the HD 6800 cards end up well ahead of both GTX 460s.

The two cards are titled “1120” and “960”, referring to the SP count of the two variants, HD 6870 and HD 6850 respectively. The first benchmark is Dirt 2, Ultra DX11 at 1920×1200, 8xAA, 16xAF. The HD 6850 ends up 33% than the GTX 460 768 MB and a good 10% faster than even the GTX 460 1 GB. The HD 6870 is just as impressive, being 20% faster than the GTX 460 1 GB. However, it fails to open much of a gap to the HD 6850, being less than 10% ahead. Considering the GTX 460 1 GB’s previous strong showings in the Dirt 2 benchmarks, on par with the HD 5850, these are some impressive numbers from the Radeon HD 6800 series cards.

A second benchmark relates to Battleforge, though the numbers are quite irrelevant as neither cards provide playable performance. The benchmark is a a 3-screen 5760×1080 benchmark, run at DX10.1 mode, comparing HD 6850 Crossfire to GTX 460 SLI. In numbers, the HD 6850 CF is 1.6x 460 1GB SLI and 3.57x 460 768MB SLI.

We have seen 3D Mark Vantage scores, and now Dirt 2 benchmarks. Weak DX11 / tessellation performance (compared to Geforce 400 Series) was one of the criticisms for the HD 5000 series. It looks like AMD has delivered with much improved DX11 performance with the first HD 6000 series cards. Performance in DX9/10 games is still an unknown, however. If the Radeon HD 6850 ends up under $200, as rumoured, it could be great value-for-money.
