Oct 15 UPDATE: Kuma to become Athlon X2 7550 and 7750. More here.
Kuma is the first (or last) dual core 65nm CPU in “Stars” family. Early in 2007 Kuma showed up in AMD roadmap. But after September AMD had made their decision that they would launch Phenom 8000 series Triple core, Because of marketing, Kuma delayed to 2008 Q2.
It is interesting that AMD branded Kuma with “Athlon”, not Athlon64 X2 or Phenom X2. Initially Kuma have two SKU, they were 6050 and 6250. Both SKU would be positioned higher than Athlon64 X2.
But because of TLB issue, AMD’s CPU product line turned out to be a mass. Kuma once again delayed. Until recently some words mentioned that AMD finally make up their mind, going to release Kuma with new SKUοΌ6500(2.3GHz)/6400(2.2GHz)/6300(2.1GHz). The CPU in our hand is the highest one, Athlon 6500.
Different from “cities” family, AMD starts their new code naming scheme in Phenom generation. Kuma is the eye of Dragon if you did some search with google. Kuma is a dual core CPU, everything is the same with Phenom X4(Agena)/X3(Toliman) except the number of cores. It is a 65nm CPU with HT3.0 support, its built-in DDR2 memory controller supports DDR2-1066, shared 2M L3 cache, Cool’n'Quiet 2.0. Like other K10 CPU, Kuma has SSE4A instruction support.
