Power5 crypto performance comparison
In a previous post, just to illustrate how traditional processors compare to the UltraSPARC T2, I posted OpenSSL results for Clovertown and Opteron processors. To broaden the comparison, here's the same data for the Power5 processor:
On a 1.9GHz P5, each core seems capable of:RSA-1024 (sign) : 275 Ops/sec AES-128-cbc (8KB) : 80 MB/sec
I would expect the 4.6GHz Power6 to do better, but even if one (generously) assumes linear scaling, its still a drop in the ocean compared to the per core per-performance of the UltraSPARC T2:
RSA-1024 (sign) : 4.6K Ops/sec AES-128-cbc (8KB) : 640MB/sec
