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.<br/></div>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)<br/><br/>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.<br/><a href=\"http://bitcointalk.org/index.php?topic=820.0\">http://bitcointalk.org/index.php?topic=820.0</a><br/></div>"
