More cores, faster password cracking

April 24th, 2009 by Vladimir Katalov

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?
