ベンチ
ヒントをいただいたので早速 -benchをやってみました。

[Jun 20 02:42:05 UTC] RC5-72 benchmark summary :
Default core : #0 (CUDA 1-pipe 64-thd)
Fastest core : #3 (CUDA 2-pipe 64-thd)
[Jun 20 02:42:05 UTC] Core #3 is significantly faster than the default core.
The CUDA core selection has been made as a tradeoff between core speed
and responsiveness of the graphical desktop.
Please file a bug report along with the output of -cpuinfo
only if the the faster core selection does not degrade graphics performance.
とんでもなく速いって訳でもないけどＰｈｅｎｏｍ? Ｘ４ ９４０（３ＧＨｚ）の倍程度みたいだ。
