Intel Releases Penryn Details

[IntelUser2000]

But that's just FP performance and the K8 architecture has always done very well in that area. Even the X2s right now are much faster than Conroes at FP. It doesn't mean it's faster in overall performance.

No it isn't. Not per CPU, not per clock. Opterons are only faster than Core 2's because they have more memory bandwidth. In single/dual-threaded apps which aren't memory bandwidth constrained, Core 2's are faster.

The claimed 45% advantage for Penryn based Xeons are also in multi-processing server markets which Xeons are heavily bandwidth constrained. It's the reason going from Woodcrest to Clovertown only gives 30-40% despite double the amount of cores.

From what I gathered, Penryn won'tb e enough to overtake AMD's new arch. Especially in certain FP area's. Penryn would have to overcome Up to a 40% advantage that Barc will have. The changes they mentioned won't be able to take that big of a leap. Just my opinion of course

There Nehalem cpu in the future looks to be a total beast. That is the ONE to look forward too.

I'm not 100% certain, but wasn't AMD's comment that Barc was 40% faster then the XEON in FP calcs "clock for clock?" And with Barcelona coming in at 2.3GHz, and Penryn possibly coming in at 3.2GHz, and also possibly being faster then Conroe, isn't Penryn going to be very competitive in FP calcs and also possibly faster/much faster in other areas?

No AMD is saying %40 faster overall in certain spec_fp2000 benchmarks. Translation: Hand picked examples from an out of date synthetic benchmark.
