An early AMD "Barcelona" revision gets its first non-simulated benchmark

Earlier today, AMD announced that it successfully demonstrated Barcelona across the server market.  The company did not publically state how fast the processor was running, the stepping of the processor, the processor thermal envelope or the eventual ship date.

We had the opportunity to benchmark the AMD Barcelona, native quad-core on an early stepping. We only had a few minutes to test the chip, but we were able to run a quick Cinebench before we were instructed to leave.

The AMD benchmark ran on a single-socket, K10 CPU running at 1.6 GHz on NVIDIA's nForce Professional 3400 chipset.  According to the system properties, the AMD system used 4GB of DDR2-667.

The most similar Intel system we could muster up on such short notice was an Intel Xeon 3220.  The Xeon X3220 is clocked at 2.4 GHz, and ran on Intel's Garlow platform (Intel X38).  This system property profile stated the system utilized 4GB of DDR2-800.

Cinebench completed the default benchmark in 27 seconds for the 1.6 GHz K10; 17 seconds for the Intel Xeon X3220.  The Kentsfield Xeon was 58% faster with a 50% higher clock frequency for Cinebench.

Both systems ran Windows 2003 R2, 64-bit.

AMD partner engineers tell DailyTech the chip we tested was the latest revision silicon.  The same engineers claim 2.0 GHz Barcelona chips are making the rounds, with 2.3 GHz already on the desktop and server roadmaps. 

AMD's current guidance suggests a late July announcement for Barcelona.  However, when DailyTech tracked down the individual partners named in AMD's press release, all cited "optimistic September" ship dates for motherboards.

Indeed, renders like Cinebench don't care about memory bandwidth.

Besides, Barcelona only supports registered DIMMs up to 667 MHz.

Aren't these meant for use in servers.. Doesn't HT perform better than FSB architecture when all 4 cores are fully loaded? Sure, there won't be a 30% performance difference. But only by this benchmark, can we conclude it fully?

The single socket comparison is useless anyway condsidering servers

Single socket comparison is not useless, since Barcelona based CPUs will be used also in the desktop and single socket servers.

I'm sure that Dailytech would be happy to benchmark dual or quad socket Barcelona systems, but it seems that they got access only to a single socket system at Computex.

It is actually not true in this form. Barcelona is a HT2.0, non-split power plane part, intended to be used in place of the older Opterons. Desktop (and some of single socket server) parts will be based on Budapest, a HT3.0, split power planes part, what - according to some reports - enables it to be clocked (much?) higher than Barcelona, as well.

Also, Cinebench is scaling rather along the clock, not along true performance. See:
So it was just the worst selection to make a test in this case...

Yeah looking at that only the Core 2 duo comes close to jump out of its spot MHz wise vs. the Performance and even then they seem to leap from maybe one position.

A truly free market requires many competitors

Agreed. So AMD must be coming up WRT performance not the otherways! :)

Also this is an early silicon. So cross your fingers for the actual stepping.

I am just thankful that Barcelona is a "real" project and not just a paper project! :)

The performance of the early silicon for the AM2 processors didn't increase much in the last 3 months before launch. But I really hope this time it will

Early silicon for AM2? All AM2 was is a package change and the move to DDR2 support. Other than DDR2 it's K8/939 on an different package. Of course you won't see any performance increase.

*AM2 is just* a package change...

The personal attack was uncalled for, but I do see your point. A little more tact, maybe. :/
