There are some Barcelona machines attached to SETI. Apparently their performance is pretty poor. See the Number Crunching forum at SETI for more.

It's being published that Barcelona may see 3.0 GHz early next year, if not by the end of this year. The reason? AMD is moving to its B2 stepping which, according to a few websites, may resolve many of the speed-hampering issues which prevented AMD from launching Barcelona above 2.0 GHz. If true, then the 3.0 GHz Barcelona may soon be in our hands making better than good on AMD's original timeline.



AMD gets B2 stepping, could see 3.0 GHz Barcelonas very soon

AMD Phenom X4


AMD's Phenom X4 integrates four cores onto a single die, each having access to both an individual 512KB cache and a shared 2MB L3 cache. It's more efficient than Intel's approach, and HyperTransport 3 lets the Phenom access system RAM at a blazing 3.6GHz (motherboard permitting).

Unfortunately, this doesn't translate into real-world performance: in our benchmarks, the Phenom 9600 tied with a dual-core Athlon 64X2 6000+ costing a third less. Give the applications a few years to catch up with multi-core technology and the Phenom might come into its own, but for now, it's a disappointment.

Even if you need a multi-core system, the Phenom doesn't distinguish itself. Intel's quad-core parts may be less elegantly engineered, but they compensate with larger data caches and faster clock speeds. The Core 2 Quad Q6600 outran the Phenom 9600 outran the Phenom 9600 by more than ten per cent in our benchmarks for a very similar price.

All Phenoms embody some neat ideas, not least a new implementation of AMD's Cool 'n' Quiet system which dynamically throttles individual cores to keep temperatures and power consumption to a minimum, but the real-world performance of the current line-up doesn't justify the price.
