AMD Athlon X2 7750 Black Edition

Introduction:

Before the year ends, AMD has one last little surprise for everyone. The long awaited "Kuma" dual-core processors based on the K10 core (Phenom 65nm) have arrived! These new processors will use the same numbering scheme at the Phenom X4 and X3, becoming the Athlon X2 7000 series. Why didn't they just call them Phenom X2's? I don't know... These processors have a 95W TDP, will run in existing AM2+ boards, and support DDR2-1066 memory speeds. Like its Phenom big brothers, the memory controller can be configured to run as two independent 64-bit memory channels or a single 128-bit (assuming your motherboard has the BIOS option for it). These processors have 64K of L1 instruction & 64K of L1 data cache per core, 512KB of L2 data cache per core, and 2MB of L3 cache shared between the two cores.

The processor we will be examining today is the Athlon X2 7750 Black Edition, running at a respectable 2.7 GHz. Being a Black Edition processor means that the CPU multiplier is unlocked, making it much easier to overclock. At a price of $79 for 1000-unit tray quantities (according to AMD's Processor Pricing List) , it seems to fit into existing Athlon 64 X2 processor prices appropriately. From what I have heard, the retail price is supposed to be more like $69. The best bang for the buck Intel has to offer near that price would be the Intel Pentium E5200, available retail for a little over $80. While the E5200 has a slightly lower clock speed and less cache, it does have one advantage of being a 45nm design (and a great chip for overclocking).

The chip itself looks like any other socket AM2/AM2+ processor.
