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.

Barcelona should be faster

I made a calculation scaling down quad-core Intel CPUs in Cinebench.
It looks like Intel should get no more but 670 points at 1600MHz. Based on this Barcelona should be faster 21% and 2.3 GHz should beat 2.66 blue quad.
For Penryn they should have at least 2.7GHz beast.

Actually the figure for Intel should be 849 points if scale it.

1274
---- * 1.6 = 849
2.4

My estimated for the stated 2.7Ghz Penryn would be about 1792 using 25% increase on chip to chip speed up.

1274
---- * 2.7 * 1.25 = 1792
2.4

One more thing time in seconds are are to estimated but my guess around 10 seconds.

One more thing its likely to be less than 25% chip to chip ( same Ghz speed ) performance increase. But I assume this because larger cache of Core 2's have made a big difference - and the Penryns have more cache than core 2 - plus cpu improvements.
