AMD Zambezi core

AMD Zambezi core and the first FX-Series microprocessors were launched in October 2011. Zambezi is based on Bulldozer microarchitecture, and it is manufactured on 32nm process. Internally, the core is organized as 2, 3, or 4 Bulldozer modules, coupled with shared 8 MB level 3 cache and on-chip DDR3 memory controller. Each Bulldozer module integrates two CPU cores, that share some circuitry, such as instruction fetch and decode logic, L1 instruction cache, L2 cache, and Floating-Point Unit. The core incorporates all technologies, found in AMD K10 microarchitecture, and adds SSE4.1, SSE4.2, AES and AVX extensions to instruction set. Currently (January 2012), Zambezi core is utilized only in desktop processors.

New core features:

  • Up to 8 CPU cores (4 Bulldozer modules) on a die.
  • Support for SSE4, AES and AVX instructions.
  • Improved Turbo Core technology.
  • Larger L2 and L3 caches.
  • Memory support up to DDR3-1866.
  • 0.032 micron technology.

FX-Series processors with Zambezi core can be identified by:

  • Part number: part numbers start with "FD", and end with "GU" for OEM parts, or "GUSBX" / "GUBOX" for boxed microprocessors.
    An example: FD8120FRW8KGU.
  • CPU ID: CPU identification number of Zambezi CPUs is 600F12.

The following table lists all AMD families with Zambezi core:

is this for real? i'm purchasing a bundle from tiger direct on friday 1.18.2013, and from what i'm told by them and from others it's almost a legand it's own right. if it's so powerful and fast why are dealers selling it so cheap?, I mean under $150.00. this type of quad core should run at least $250.00. i hope i'm not in for a disaster. if it fails tiger directs return policy is very friendly and others i don't know.

I bought one almost a year ago, game everyday, its stood hard as a rock, best 149 bucks spent. I also did a bundle from tiger,( actully many) teamed with gigabyte 990 fx uda 5 mobo, 16 gigs vengence ram, twin raeons, one bad rig for the price. So its a deff a good buy

This cpu is awesome. I have over clocked it to 21.0 and it is amazingly fast. Using a 970 Motherboard and they seem to be a match made in heaven. I really see it running on all games like Company of Heroes, BF3 and Hawken. There is no denying that AMD went out of their way on this one.
