Here's some quick K8 results @2GHz specint base=9.77 rate=10.8
specfp base=10.4 rate=10.9
This is way too close. Either there is something wrong with the K10 IBM system or K10 is going to be a huge disappointment for everybody except the HPC crowd. I would wait for at least a couple more results to get published. Just look at the problems stephen has been having with the various Bioses.

Um why we looking at single threaded benches on a Native Quad Core,Im confused.The power of the platform is that all the cores can talk to each other very quickly.The only thing I dont understand is the SSE should be twice as fast as K8,even on a single thread,One thing I know for sure is on my Quad FX ,setting memory speed to less that 800,even with lower latency timings slows it down,also setting the bios interleave all(disabling NUMA)kills it.It seemed S7 has that problem.Comparing an Intel with slower memory timing proves nothing because the platforms are totally different.In my tests nothing can use a dual socket AMD system as well as SUSE linux.Windows XP x64 sometimes takes 20 minutes to figure out its not using local memory and then move the thread so it does.Vista wasnt much better.Off node hits kill the AMD 2P .The Desktop Quad AMD will be using HT3 and have alot more memory bandwidth than Barcelona, I also heard that at a certain clock speed it has some kinda power band that kicks in that amazing,since the person who said that was one of the first to provide bench marks .Im gonna guess thats right.Barcelona had to plug into an old socket and run and it does but not as fast as it will in a new socket.I know this Barcelona scales better than lineir that has never before happened in the history of processors,example 1 processor scores 50,2 processors score 110,history says 2 processors are about 30% faster than 1 or 65Quote:

Nothing of desktop performance was indicated at all. And they're planning to launch a 2.6GHz Opteron 23xx model by end '07 too.

Just to make it easier for people. Thanks for the heads up Phil...Quote:

2360SE it's 18%-22% faster then 2347... not bad, perfect scaling would be 25%.Quote:

@Smartass unless you can prove that Quad xeons communicate faster through the FSB than K10 does internally i say you are making that up.

Enrol yourself into our NEW CAMPAIGN !!! :eek:
It's Codenamed WFAL (pronounced Waffel) campaign and you'll love it :up:
What do we do in our campaign? :D
We WFAL !!! Or WAIT FOR ACTUAL LAUNCH !!!!
Don't compare C2D and Barcelona, wait for launch of desktop parts this Nov/Dec. :mad:

Btw, you could use a spell checker.
I noticed this when it was published.Quote:

As far as communication between cores. By definition of the program, memory systems would come into play and who knows how accurate the program is too begin with. Finally, I'm starting to feel like Perkam, this is just getting to be a little obsessive. Time to wait for the Phenom launch.
LOL! I've found 6 other articles in Eastern sites that were copied off ATs Barcelona reviews, word for word. :DQuote:

I've got one question tonight...
Ok, Barcellona uses HT1.0.
Phenom uses HT3.0
Phenom FX uses HT3.0
What about FASN8???????????? :D :D :D
I was meaning no offense, just stating my own frustration :up:Quote:

Another question:
if I would build today a dual 23xx based opteron, with two processors, around 4Gb of RAM (that would possibly increase with time) and two HDs... What sort of PSU should I use? "How much power" it should have?
Thanks a lot.
Zippy 700, PCP&C 750?
Without a vid card, a class 400W is more than enough as you'll see in reviews for peak VAC consumption.
