AMD X3 @2.8ghz

~3800khs ~150Watt
你试过 -4way 吗？

24 核机器能期望多少哈希？我有个四核每秒生成 4,300 哈希，我估计 24 核机器挖比特币能到每秒 25,000 哈希。
AMD Phenom（我记得是 4 核）CPU 用 -4way 大约 11,000khps，快约 100%。24 核该有 66,000khps。AMD 是最好的选择，因为它的 SSE2 实现最好。（或者是因为 tcatm 用的是 AMD，按它优化了代码）
还有太多别的事要做，我还没时间把 -4way 做成自动。目前还得手动。

Did you try -4way?

How many hashes can I expect with a 24 core machine? I have a quad-core generating 4,300 hashes-per-second, so I am estimating a 24-core machine could mine bitcoins at 25,000 hashes-per-second.
AMD Phenom (I think 4-core) CPUs are doing about 11,000khps with -4way, about 100% speedup. 24 cores should get 66,000khps. AMD is the best choice because it has the best SSE2 implementation. (or maybe because tcatm had an AMD and optimised his code for that)
There's been so much else to do that I haven't had time to make -4way automatic. For now you still have to do it manually.
