Photos, benchmarks of dual-core Phenom surface

Remember how a trio of dual-core Phenoms suddenly popped up on an Austrian price-matching site last month? Well, the chips still don't seem to be available yet, but a fourth specimen has somehow made its way into the labs of Chinese tech site Expreview.

A top-down photo of the CPU package shows AMD Athlon branding and a "6500" model number, but CPU-Z identifies the chip as a Phenom 6500 Black Edition. This chip definitely looks like a Phenom derivative, too. It has 2MB of L3 cache, SSE4A instruction set support, and a "B3" revision codeā€”the same one that identifies erratum-free Phenom X4s.

Chopping two cores off a Phenom X4 apparently didn't let AMD push clock speeds any higher: the sample runs at a lowly 2.3GHz. That said, Expreview's benchmarks show the specimen outrunning a 2.3GHz Athlon X2 5000+ Black Edition in SuperPI, 33.43 seconds to 39.374 seconds. Those kinds of gains may not be enough to make dual-core Phenoms competitive with, say, Intel's Core 2 Duo E8400, but they could help AMD in the sub-$100 market.
