14 DAY TRIAL // The first pieces of news on AMD's upcoming 65nm K10 dual core processors have started to emerge to the web. The Kuma based Athlon X2 7750 chip seems to have got into the hands of the guys at Donanimhaber, who subjected it to some benchmarking tests to see what the CPU was capable of. The clock speed of the Athlon X2 7750 is set at 2.70 GHz and is complemented by a HyperTransport 3.0 system interface.
Other specifications of the chip include 512 KB of L2 cache per core, and a shared L3 cache of 2 MB. The chip was tested on a Foxconn A7DA-S (AMD 790 GX + SB750) motherboard, which sported 2 GB of 800 MHz DDR2 memory. The performance of the CPU was then compared to that of the Intel Core 2 Duo E8200, Core 2 Duo E8400, Core 2 Duo E6420, AMD Phenom X3 8750 and Athlon X2 5200+ (Brisbane), all running at stock speeds.
The benchmarking tests the Athlon X2 7750 was subjected to include 3DMark06 (CPU Score), CineBench 10 (64-bit), wPrime 1.55 (32M), and Fritz Chess. Besides that, the Cinebench 10 test was also run while the chip was overclocked at 3.30 GHz.
The results of the tests place the upcoming Athlon X2 7750 “Kuma” somewhere between the Athlon X2 5200+ and Core 2 Duo E8200 on a broader performance scale. The new chip comes with L3 cache, as well as with other K10-specific optimizations, which give it a good advantage over the Athlon X2 5200+ “Brisbane” running at the same speed. On the other hand, the Intel Core 2 Duo E8200 remains ahead, although it is outpaced at wPrime.
The guys from Donanimhaber ran the tests while the chip was overclocked at 3.10 GHz, along with a Cinebench run at 3.30 GHz. An AMD Overdrive session allowed them to push the core speed of the processor to 3.40 GHz. You can read the review of the processor here.
