Athlon 64 X2 gets the 65nm treatment

AMD today announced its long-awaited 65nm Brisbane core Athlon 64 X2 processors. This begins AMD’s transition to 65nm from 90nm. AMD expects to transition its complete product lineup to 65nm in mid-2007. Nevertheless, four Brisbane core Athlon 64 X2 processors are launching today—the 5000+, 4800+, 4400+, and 4000+. All 65nm Brisbane core processors are equipped with 2x512KB of L2 cache.

AMD Athlon 64 X2 Brisbane 
L2 Cache
TDP Pricing
5000+ 2.6 GHz 2x512KB 65W
4800+ 2.5 GHz 2x512KB 65W $271
4400+ 2.3 GHz 2x512KB 65W $214
4000+ 2.1 GHz 2x512KB 65W

With Brisbane, AMD Athlon 64 X2 dual-core processors equipped with 2x1MB of L2 cache will become a thing of the past as AMD completes its 65nm transition. While AMD has announced its Brisbane core 65nm processors, the processors only available in limited quantities. Expect mass availability in Q1’2007.

OEMs are expected to deliver Brisbane powered systems as well. These OEMs include Acer, Dell, Founder, Gateway, HP, Lenovo, Packard Bell and TongFang. Dell is expected to adopt Brisbane 65nm processors in its Optiplex and Dimension desktops while Acer is expected to have Brisbane powered Aspire systems too.

Pricing for Brisbane 65nm processors start at $169 for the 4000+ and goes up to $301 for the 5000+ in quantities of 1000. Do note that Brisbane core processors are still K8 based and not K8L like the upcoming Stars core processors.

RE: now the question is, how high do they clock?

Well FX 74 work on 3 GHz, and they are also 90 nm. I think that there is no point to expect anything better from AMD on k7 architecture (an its extensions). They will never beat core 2 without a good redesign or completly new product. K7 was a hell of an answare to P4, but so is core 2 to K7, they just dont belong in the same generation. 60 nm chips will bring some more mhz, but i thing that is not their purpose. This is only a step for amd (in my opinion) to prepare itself fo the next generation, and to try to solve the supply problems it has been having. They already produce more working dies per waffer than thay had recived with 90 nm waffers. I bet that in some time they will improve efficency even more.

Err, don't you mean K8? The Athlon64/Opterons? Or did you in fact mean the K7 Athlon/AthlonXPs Socket A? K7 did indeed beat out P4 at the time but K8 really improved the performance lead even more, clock for clock.

The K8 was really a K7 with some tweaks, 64 bit extensions and a memory controller strapped on. The major preformace improvements was from the memory controller. AMD did not change very much in the core logic from the K7

They didn't change the backend very much, but a number of changes were made to the front end. Decoding, the MMU/TLBs, the layout of the pipeline, cache interfaces, etc where all substantially changed or even outright replaced. While you're right that the memory interface was the biggest single change, collectively the other stuff is probably equally important.

Yes, and Intel really didn't change 'that much' from Pentium 3 to Core 2....
