Benchmarks for CPU's

I have been doing some benchmarks on a couple of different systems for LIO's. I have been using Kevin Closson's great SLOB toolkit.  You can find more information about it on his blog here.

I have been looking at 2 different systems, and here are my results
These 2 systems are both HP.

The first is an AMD 6276 server. 2 socket x 16 cores. (465 G7)

./runit.sh 0 40
The awr is posted.

Here is the summary of throughput.

       Rollbacks:                0.0                0.0

I then looked at the new Intel E7 2870 I got.  2 socket 10 core, dual threaded (BL620 E7)

./runit.sh 0 43

the awr is here

       Rollbacks:                0.0                0.1
    Transactions:                0.4


Look at that throughput.. the 43 process count looks to be the best throughput of over 13 Million LIOS/second

WOW  the new AMD Bulldozer has great numbers, but the intel really Rocks !
