Comparing the UltraSPARC T2 peak cryptographic performance with a number of current processors:
| Cipher | 2.2GHz Dual-core Opteron | 2.67GHz Quad-core Xeon |
1.9GHz dual-core Power5 |
1.4GHz UltraSPARC T2 |
|---|---|---|---|---|
| RSA1024 (private key) |
2.3K Ops/sec |
4.8K Ops/sec |
0.5K Ops/sec |
37K Ops/sec |
| AES-128 | 1.6 Gb/sec |
4.2Gb/sec | 1.3Gb/sec | 40Gb/sec |
clearly highlights the almost 10X performance advantage that the UltraSPARC T2 processor is capable of delivering on a per-socket basis. Further, it should be noted that because the UltraSPARC T2 is offloading the processing to cryptographic accelerators that run in parallel with the cores, the processor is still largely idle when delivering significant crypto performance -- in stark contrast to the traditional processors which are 100% busy when performing crypto processing, as illustrated in the following figure:

Finally, even if traditional processors are enhanced with cryptographic accelerator cards:
| Cipher | Sun SCA6000 | Cavium Nitrox PX | 1.4GHz UltraSPARC T2 |
|---|---|---|---|
| RSA1024 (private key) |
13K Ops/sec |
12K Ops/sec |
37K Ops/sec |
| AES-128 | 1.0Gb/sec | 2.5Gb/sec | 40Gb/sec |
they are still outperformed by the UltraSPARC T2.
