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.

ehh to my opinion nvidia nforce 3400 is a socket am2 board...
so we are seeing budapest here, not barcelona.

and if am2 you also have less performance due to the board, not to mention the early bios phase.

anyone care to explain?

The main difference between Barcelona and Budapest is the socket. Thus, people use term "Barcelona" to describe whole range of K10 based products, just like people are using "Penryn" to describe 45nm desktop and server products (even though Penryn is a codename for a mobile chip).

if am2 you also have less performance due to the board

Why would AM2 boards would have less performance? Actually, all Opteron 1000 series CPUs use socket AM2:

No Budapest also has HT3 while Barcelona is still HT1. Also what makes you think that its impossible to make a Socket F nf3400 board. There is no technical limitation preventing it.

Yes Nforce 3400 is an AM2 board.

And this is budapest, because its a 1P processor.

There probably would be a performance loss associated with using an AM2 board, not sure how much though. In this case, probably a fair bit as it would have been using all 4 cores.

No way to tell until we get more detailed benchmarks with AM2 and AM2+ boards in a variety of different situations. And preferably closer to final silicon.

Actually, these are effectively what your going to get on Bareclona, albeit this is only 1P, as they are sticking to HT1.x and Socket F Registered DDR2 for the first interation of the server SKU.

The improvements to I/O with HT3.0 won't really affect Single Socket systems, and are more geared toward the multi Socket platforms. So your maybe looking at 2-5% more with DDR2-800 on the desktop.

It was always going to be a close race in the Uni-processor arena, it's only in Multi Socket systems AMD's server based architecture gets to shine.

Though it is a little worrying if they are suppose to be launching in July and they are only demonstrating silicon at 1.6GHZ vs the rumored 2.3GHZ launch speed.

Some people are still clueless about AMD's platforms.

Please explain to me WHY Socket F board with one populated socket would be faster than Socket AM2 board (as long as CPU and memory run at the same speed)?

I think he meant AM2 compared to AM2+. Anyway if he meant socket F the opposite would be true as socket F uses registered ram which has a slight performance penalty and therefore an AM2 system would probably use slightly faster memory in most cases. Otherwise both Socket F and AM2 1P systems should perform identical
