fah官方论坛上有个老外报告说
I'm running the latest GPU client on my radeon 4850.
I was previously running on 3870 getting 1500ppd but that has dropped to 450ppd with new Radeon 4850.
Is there a problem with 4850 and GPU2 client?
My system

790FX motherboard
4GB DDR1066
Phenom 9850 @ 2.5Ghz
Sapphire Radeon 4850 @ stock
Vista home prem 64bit
Catalyst 8.6
GPU client 6.12beta6
然后有人说AMD的开发工程师给出解答
The code needs to be retuned to scale from the 320 SPs in the 38XX boards to the 800 SPs in the 4850. At the moment, at least on the smaller proteins FAH is currently running, the 4850 is a little faster clock for clock than a 38XX, but the clocks are lower so it's currently a small drop in performance. We are tuning away, but it's going to be a little while until things are tweaked to utilized the 2.5X increase in SPs in the 4850 over the 38XX boards. We went for stability first, and are now just a little way into a heaving tuning pass. 2XXX/3XXX will get faster as well, but the 4XXX has the most headroom.
