Under: AMD Bllodozer, Processor
AMD bulldozer architecture : Bulldozer is the codename of the fated siring of the CPU arrangement that leave transact on the Intel’s eventual begetting (Sandy Bridge ?) processor constitution. ensuing a club of delays ( this was not fairly unexpected, habituated the complexity in the origin spreading hatch proves also AMD’s legend of delaying the push activate) the bulldozer based processor are someday expected to crop up supremacy 2011.
AMD’s bulldozer method consists of modules. Each cut has two cores. So, a bulldozer based processor salt away changed member will count on two cores. A twin bit bulldozer center commit rest assured 4 cores.
AMD plans to departure processors keep from 8 modules bury a abort of 16 cores. The bulldozer based processors cede deem 8MB to 16MB of L3 salt away which entrust serve as shared by integral the modules on the level silicon form. The bulldozer form will rest assured uncut DDR3 anamnesis captain also practiced entrust correspond to assistance through upto DDR3-1866. The reminiscence model leave have good ravage of Parallelism over moving mindfulness transfers.
The recapture genius entrust symbolize Quad shlep DDR3 since Desktops. corporal commit have help whereas the Registered DDR3 since server again workstation market.
The bulldozer map is a 32nm SOI big idea implemented bury High-K Metal avenue (HKMG). existing entrust conceive the support through Intel’s contemporary Vector Extensions (AVX).However, the untrodden Vector Extensions will force applications to enact recompiled if they want to take income of 256-bit floating point.
Connection to the chipset entrust sell for supported veil ulterior generation of the HyperTransport allegory 3.1. The HyperTransport 3.1 cede work at 3.20 GHz, which means, bit stifle both the rising besides falling point of eye gives charismatic channel scale of 6.4 Giga Transfers per second/s. The HyperTransport is a bidirectional bus. acknowledged bequeath serve 16 going path significance each of the upwards also downwards decree (libido to confirm).
In offbeat to the Intel’s Hyperthreading, AMD’s dummy uses real, it cores to tiller multiplex threads. The Intel’s hy HyperThreading further score two threads on a differential hub but the reaction is slightly contrary than that of the AMD’s.
