AMD Bulldozer architecture that has 8 cores is given a code name Zambezi, this processor heralded series is able to outperform Intel’s Core i7, which has a series FX 8120 and FX 8150. This processor is designed with high performance processor architectures from AMD and optimized to provide communication between cores better and higher instruction in units of clock cycles. In addition, the processor can be configured up to 8Mb bulldozer capacity of L3 cache between cores available.
Bulldozer Modules
AMD has introduced a new micro-architecture block called ‘Module’. In the world of today’s modern hardware, a module is a middle path between a processor ‘dual core’ (in this case are independent of each core) and a processors ‘single-core’ which has had two ‘threads’ SMT (in which each thread to share hardware resources with other threads).
A module consists of two bonding machines of conventional x86 processors, and processors are split between the FPU and the L2 cache into a single unit of a module. If it is shortened, then a module having as many as 213 million transistors on a 30.9 mm sized square acres (including the 2mb L2 cache). So a processor ‘dualcore Bulldozer has a module,’ quad-core ‘bulldozers have two modules, and’ octo-core (8-core) Bulldozer has four modules.
AMD Bulldozer Technology
Technology was first introduced to 11-metal layer 32nm in the manufacturer as HKMG (High-K Metal Gate). Implanted inside a ‘Core Turbo Boost’ to increase the clock frequency to 500 MHz on each of the active core. This chip works at 0.8 to 1.3 V, the clock speed of 3.5 GHz and above. Use of power between 10-125 watts. Use powernya between 10-125 watts. L3 cache are held for more than 8Mb on each module, 16MB per 8 modules and so on, divided into four sub-cache ‘. from 2 mb each, while working at 2.4 GHz at 1.1 V.
This last technology already supports DDR3-1866 RAM, Dual Channel DDR3 PC3-15000 for the desktop, Quad Channel DDR3 PC-12800 (DDR3-1600) and DDR3 registered for the server / workstation. And fully supports socket AM3+.
Processor
When first introduced, the Opteron ‘is the beginning of the Bulldozer. And now the FX-6100, FX-8120, and FX-8150 that was released October 2011 and comes with the title Zambezi, where the latter will still have more improvements in the first quarter of 2012. AMD has also prepared two series Bulldoser for servers, Opteron 4200 series as Valencia, who has more than 8 cores and Opteron 6200 with the name Interlagos, which more than 16 cores.
Motherboard compatibility
AMD informed its FX processor will use socket AM3+. Only motherboards with support for AM3+ BIOS / UEFI which officially will be supported bulldozers. One of the motherboards that are ready to Bulldozer is ASUS Crosshair formula V AM3+. This motherboard based on AMD 990FX chipset that offers six ports SATA 6Gbps, a significant increase compared to 2 ports 6Gbps on intel chipset series 6.
