Thread: AMD Phenom 2 X4 955 central processing unit

The AMD platform has long been familiar for its backwards compatible platforms with AMii+ central processing units capable to function with the AM2 CPU boards with a BIOS upgrade, and just the AM3 central processing units capable to utilize the similar AM2+ motherboards with DDR2 memory meaning the complete cost of ownership for a fresh system with an AM3 central processing unit is potentially much without than the equal Intel central processing unit with a latest CPU board and DDR3 memory combination. The 955 Black Version CPU is capable to outperform the 810 CPU we utilize in platform trying across the board with higher function.


AMD and Intel are opposing for control of the computing dollar from clients and businesses and have been for years. In the Computer space, Intel rules the roost in conditions of pure function with their Core i7 central processing units being quicker than the equivalent AMD central processing units in virtually complete sense. AMD, however, is not testing to compete exactly with the Core i7 central processing unit but with the lower priced Core 2 Quad and Core 2 Duo central processing units and they have been succeeding with CPUs that are quicker for the similar cost as equivalent Intel central processing units.




AMD established their AM3 CPUs before this year with processors ranging in velocity and function from the Phenom 2 X4 955 Black Version being here to the Athlon 2 X2 CPU that marks the low-end of the spectrum. The well thing about the AM3 is that it is backwards compatible with Socket AM2+ CPU boards, now missing DDR3 support when migrating to the fresh CPU Socket on an former motherboard. Current review is on the quicker of the AM3 CPUs, the AMD Phenom 2 X 4 955 Black Versions.


The Phenom 2 is AMD’s first architecture construct on the 45nm Silicon on Insulator function at their manufacturing plant in Dresden Germany. Every Phenom 2 CPU is 258mm2 in size and has 758 million transistors. The central processing unit has 128KB of L1 cache (64KB Data+64KB Direction) each core, 512KB L2 cache each core and a Six MB L3 cache shared through all cores.


AMD has traditionally permitted former CPU boards to be upgraded with latest central processing units since the advent of the Socket AM2 platform. The AM3 CPU has 938 pins which is 2 without than the AM2+. The pin configuration is identical minus the 2 pins, meaning you can set an AM3 CPU on an AM2+ motherboard. The reverse is not fact as the AM2+ central processing unit would have two additional pins that would not set on an AM3 interface.
