AMD revealed that its plans a 12-core Opteron processor in 2010, and a 16-core Opteron in 2011. Unfortunately, almost no further/technical details — more cores is definitely good, but we’d like to see whether AMD is able to implement SSE2 effectively. Right now, SSE2 instructions are executed much slower on AMD processors than on Intel ones, while they’re really important for SHA-1 (the most password checking routines are based on). Or may be SSE5 will give provide additional benefits for password cracking?

According to Tweak Down, AMD will start shipping them next month. We’ll see how do they compare with Intel Gulftown.

New member of Core i7 family: six cores, hyper-threading, and some new instructions — including ones for AES encryption. Unfortunately, useless for our password-cracking purposes: most password-checking routines are based on SHA-1. But anyway, an ability to run 12 threads at a time will definitely increase the performance. We’ll see (in Q1’2010). More info at Tom’s Hardware.
