AMD Athlon X2 7850 Black Edition

Review: Good performance for €62

It's been quite a while since we reviewed the AMD Athlon X2 7750. Last week AMD released a 100MHz speed bump, the Athlon X2 7850 Black Edition, and apart of the speed jump, the rest of the specification is the same as Athlon X2 7750.

So, it's still a Phenom with two cores disabled, but not disconnected. Both of them are still based on 65nm K10 core, codenamed Kuma, while in Q3 there should be a new dual core based on 45nm process that might fix AMD's dual core odds. The CPU features 2x 64kB instruction and data 1st level cache, 2x 512kB 2nd level cache and additional 2MB shared 3rd level cache. The disappointing news is the TDP of 95W. AMD is positioning this CPU against the E5300, with a TDP of 65W and as you can see, TDP difference is quite substantial.
