AMD Zambezi ''Bulldozer'' Desktop CPU Roadmap Revealed
AMD's next-generation PC processor architecture that seeks to challenge the best Intel has, codenamed "Bulldozer", is set to make its desktop PC debut in 2Q next year, with a desktop processor die codenamed "Zambezi". AMD is seeking to target all market segments, including an enthusiast-grade 8-core segment, a performance 6-core segment, and a mainstream 4-core segment. The roadmap reveals that Zambezi will make its entry with the enthusiast-grade 8-core models first, starting with 125W and 95W models, trailed by 6-core and 4-core ones.
Another couple of architectural details revealed is that Zambezi's integrated memory controller (IMC) supports DDR3-1866 MHz as its standard memory type, just like Deneb supports DDR3-1333 MHz as its standard. DDR3-1866 MHz, or PC3-14900 as it's technically known, will churn out 29.8 GB/s in dual-channel mode, that's higher than triple-channel DDR3-1066 MHz (25.6 GB/s), which is Intel Core i7 LGA1366 processors' official memory standard. The 8-core and 6-core Zambezi models feature 8 MB of L3 cache, while the 4-core ones feature 4 MB. Another tidbit you probably already knew is that existing socket AM3 processors are forwards-compatible with AM3+ (Zambezi's socket), but Zambezi processors won't work on older AM3/AM2(+) socket motherboards.

I think I'll be getting a mobo first then maybe a proc, we'll see though.
Then I can get am3 cpu to tide me over : ]
that amd is the one who will be doing a proper smack!
Also meh.
I do not think these will be the saving grace AMD needs.
Next year will be interesting with Sandy, Bulldozer, Keplar and Southern Islands.
Unless they've changed how they're doing things in the past 6 months :laugh:
tdp is the same as phenom II 125w-95w
Do we have confirmation that they have something similar to hyper threading and how it actually works?
How ever each bulldozer module ( 2 cores in os) can process two threads fully at the same time.
Edit: can 1 Bulldozer module handle 1 thread, or 50% of the module will be idle?
We will not market modules, we will only market cores; modules are how the designers lay out the processor, but that will not be part of the marketing or naming.
