Phenom X2 chips to boost performance per clock
As performance evaluations will soon show, the Phenom/Athlon 6500 isn’t anywhere close to the performance of the X2 6400+. However, architectural improvements meant that Kuma outperforms Brisbane (K8, 65nm) on a clock to clock basis. To ascertain this, Expreview used a Athlon 64 X2 5000+ Black Edition (Brisbane) that was underclocked to 2.30 GHz, the clock speed which AD6500 comes with. Super Pi 1M benchmark was run. While the Brisbane chip crunched it in 39.374 s, Kuma did it in 33.43 s indicating a performance increment of roughly 15%. The test-bed consisted of a NVIDIA nForce 750a SLI motherboard and GEIL 1GB DDR2-800 memory. Kuma AD6500 comes with a shared L3 cache of 2 MB apart from dedicated L2 caches of 512 KB per core. It uses a broader HyperTransport 3.0 system interface at 3600 MT/s. It supports DDR2-1066.
