No need to. The difference is there on 1 core as well. I will send you the excell sheet.
You are right for the 1core. I got carried away by your 582 582 result of DS 12 on C2Q.
But still, how can you have reproducible (or even close) numbers with multicore?

And you are right here! I just thought about it for a moment and of course it might be that a core stuck in a difficult position and the whole nodes go down or up!! (and I checked with 2 Engines and saw some differences)

Actually this is even more suporting my point that you cant adjust differnt hardware with just one time adaption to be "identical" ... :-)

As I am not happy with the standard Benchmarks to compare a CPU I run a bit of a more extensive Test with 20 Single Engines. This is the result:

The colored numbers at the end might help calculation your desired speed.

The AMD 6 core 1055T in this test is running with 0.1V below the specification by AMD. With a 29€ air cooler it is at 40°C when all 6 cores are running! Looking at the price of this it isnt the worst choise!

Since the 1055T is in the same price bracket as the i5-750, which is also a very strong overclocker, do you know how it does?

Good question ...

The I5 is in average 20% faster per cycle and if you go to an extreme you might be able to OC a bit more ... but the 1055T has 6 cores ...

If you analyse your own or any GM game it doesnt matter, if you want to analyse with single engines I would prefer the 1055T, if you want to play on a server I would go for the 750 ... if you mix this usage it is on you again :-)
