Benchmarks :http://we.pcinlife.com/thread-786552-1-1.html
Tests were run w/ Catalyst 7.6 and Forceware 158.24 drivers.
EDIT: It seems alot of the tests were run with FW 158.43, not 158.24.
Unfortunately they didn't test against the 8600GTS, but they compare the HD 2600XT, 2600 Pro, 2400XT, and 2400 Pro against the 8600GT, 8500GT, 7300GT, and 7300GS in alot of tests.
In DX9 performance, the HD 2600XT is faster than the 8600GT in the vast majority of cases, sometimes by a large margin, sometimes by a small one, and a few times it loses. At the 1600x1200 resolution, the 2600XT wns every test but one (FEAR).
When it comes to the HD 2600 Pro vs 8500GT, at 1024x768 the 2600 Pro wins every time, often it is much faster.
The HD 2400XT appears faster than the 8500GT in DirectX 10, in DX9 they are not compared. It is, however, consistantly faster than the 7300GT. The HD 2400 Pro is only featured in one 3D Mark 06 benchmark; here it is slightly slower than the 7300GT and much faster than the 7300GS.
In terms of DirectX 10 performance, it looks like a resounding win for the HD 2400/2600 series, except in Lost Planet. In Call of Juarez and Company of Heroes, the HD 2600XT and even the HD 2600 Pro are faster than the 8600GT and the 8500GT is left in the dust.
As I said earlier, the HD 2400 Pro is able to beat the 8500GT in DX10 (except for Lost Planet, once again).
Overall, it looks like AMD has a strong midrange and low-end this time around, although the HD 2600XT will not be much faster (and in some cases will be slower) than the 8600GTS. The one thing that looks clear is that AMD has very strong DX10 performance, although this might have been less of a win had beta nVidia drivers been used (v158.45 improves DX10 performance over 158.43).
Personally I think nVidia cut down the 8600/8500 series too much in terms of shader units. The 8600 is strong, and should be, in texture heavy games due to having twice the number of TMUs as the HD 2600 (16 TMUs vs 8). However, it has a big problem in terms of shader performance due to only 32 SP's. I think this is what is killing DX10 performance, and performance in more shader-heavy games.
One other thing that we can take from this is that the 7.6 drivers really improved STALKER performance; the HD 2600XT beats the 8600GT here and that would have been impossible on the old drivers.
