I don't know about Shanghai, but cpufreq works great with my Phenom II X4 940 and supports all four CnQ modes (3000 MHz, 2300 MHz, 1800 MHz, 800 MHz).

Hi,
I'm curious, when testing the Shanghai Opteron CPUs in Linux, did cpufreq work?
Were you able to change the frequency of the cpu's through linux?
Or did the BIOS not support this.
Thanks,

Load it up with as much RAM as it could accept, a kickass video card and some fast disk storage and you'd have a winner!

ooooooOOOOOOooooo I'm excited for you! :P
Let us know how it goes

I think it would have been more interesting to see a 2356 OC'd to 2.7ghz in this comparison so we could have a better perspective on what the clock for clock improvements are. In any case, I'm very enthusiastic about these new cores

Originally posted by Thetargos View PostFor the current Opteron Shanghai cores, yes. But the desktop Phenom II CPUs will use virtually the same cores (with a few changes, like no ECC memory requirement and faster RAM). This, though, should give perspective on what could we expect the performance be like for the Desktop versions. Like Bridgman says, currently the tendency to determine he "best" CPU seems to be "what do you want to do with it?" question which might still be relevant for users who simply want a "general purpose" desktop PC.

Originally posted by deanjo View PostOn that note though doing a head to head on such systems should really have more tests relevant to what such a setup would be used for which would be typically server use. Right now PTS is a bit bare in that department. I really doubt for example mp3 encoding will be a big selling feature of server chips where as apache performance, many thread dbase queries, power usage, vitualization etc would be more a concern.

Yeah... right now the benchmarks all seem to say "AMD is faster on a bunch of things, and Intel is faster on a bunch of different things, and the better CPU depends on which things you think are most important".
Bah !!

Originally posted by Thetargos View PostInteresting findings indeed, alas, without proprer "contrast" (AKA Intel parts performance) these results only show that indeed the Shanghai cores are an overall improvement from the Barcelona parts, which is good and all, but to add perspective, it would be better to have Intel numbers as well (for both present and past generation, as well)Last edited by deanjo; 02 January 2009, 07:27 PM.
