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.

AMD is going to 1/2 multipliers in order granulate their bin splits. Prior, AMD would make 200 increment model number steps by 200 MHz clocking delta coupled with 512 or 1 meg cache.

Since the die size is substantially larger for 1 meg cache on a dual core product, they did away with the 4000+, 4400+, and 4800+ at 90 nm. However, this has a deleterious affect on revenue... why? Say you have a processor that just barely fails the 2.4 GHz bin but would run great at 2.3 GHz ... but you don't have a 2.3 GHz division so you must sell it as a 2.2 GHz which commands a lower price.

Now, you can do this one of two ways, create a processor that gives high clocks and stable processors over a range of clock speeds in which case an integer multiplier would do just fine... but, implementing a 1/2 multplier simply means they cannot get the clocks to go high enough and the distribution is such that they cannot bin/granulate the product to make the most money.

In order to increase revenue AMD wants to sell up that is try to get more money for 100 MHz by labeling it as a 200 model number increase, in short, they are selling you on the fact that 100 MHz is actually 200 Model number better. Perhaps it is.... it is all scale and relative performance, which right now takes up the low end no matter the clock.
