2x6850 or 2x5870

post #1 of 11
Thread Starter 
Performance-wise.

Curiously asking. I'm wondering whether the scaling difference actually helps the 6850 overcome the 5870...

No the 2x5870 would beat the 2x6850 up and down . 5870 is comparable with 6950 unlocked and 6970.

Any solid proof? Benchmarks, comparisons, anything?

Please no anandtech, I don't see the way they can have every single product in existence and bench it all. They don't even list the system they used for every single one of their benches...

If you were asking whether 6870 CF is equal to 5870 CF then i'd say yes it is but 6850 CF would be sub par.

You can get similar results with 6850s over 1Ghz core though.

I don't think there are any published head to head reviews, but TPU, G3D, and Legit R all have 6850 CFX reviews.
You could extrapolate from those.

Here are some of my 5870 CFX results.

Vantage, SB vs C2Q

3DM11, SB vs C2Q

M2033 with SB



And SB crysis runs, stock cpu and overclocked.

A single 5870 performs about 1-2% worse than a 6950, and maybe 5-10% better than a 6870.

Two 6870s scale much better than two 5870s, so two 6870s end up with maybe 10% better performance than two 5870s.

Two 6870's are slightly more powerful than two 5870's, so I imagine that...

5870 XFire is more powerful than 6850 XFire.
