The demo of AMD's Barcelona...

[lapdog]

Booting Widows with a unstable CPU happens all the time. Sure it's a good sign, but nothing worth a demo.

And the estimated performance charts...how can they estimate anything with out a slated clock speed. 100% BS.

Anyone got benches handy to compare the 2220 SE, Xeon 5180, and 5355 to see if they are close to "on par" with the graphs?

SPECfp_rate:
fastest 2S Opteron 2220SE score is 96.0 (peak)
fastest 2S Xeon 5160 score is 83.4
fastest 2S Xeon 5355 score is 104

40% faster than the 2220SE gives a score of about 135-140 for a 2S, quad-core Barcelona. By comparison, a 4S Opteron 8220SE has a best score of 178.

SPECfp_rate is heavily memory bandwidth dependent and really isn't indicative of desktop application performance.

OLTP benchmark:

It's not specified but my guess is it's TPC-C, one of the most important enterprise benchmark. I think the existing systems mentioned in the test are:

Opteron 2220SE - HP DL385G2 with a score of 139,693
Xeon Woodcrest - HP DL380G5 with a score of 140,246
Xeon Clovertown - HP BL480c wth a score of 222,117 (~60% higher increase versus the Woodcrest system, which matches the graph)

A 70% increase over the Opteron system gives a score of around 235,000-240,000.

The best score for a Clovertown system currently is the HP ML370G5 with a score of 240,737.

The best score for a 4S Opteron system is the HP ProLiant DL585G2 with 8220SE with a score of 262,989. The best score for a 4S Intel system is the HP ProLiant ML570G4 with Tulsa-based 3.4GHz Xeon MPs with a score of 318,407.

Sure! But only if cache is making soft errors or problem is in SSE/FPU units! If your ALU is faulty then simply you will get BSOD .
