Update: AMD To Ditch Initial AM2 2x1MB Cache Desktop CPUs

AMD pushing 2x512KB chips instead
Not to the surprise of
, AMD representatives are telling its CPU distributors to play down 2x1MB L2 cache
processor sales in favor of the 2x512KB AM2 parts. Several days ago,
published the entire AMD
July 24th pricing guide
complete with price cuts across the board. The price list was surprisingly devoid of AMD 2x1MB cache CPUs, and today we know the reason why.
Several US distributors all confirmed the same story with
, either claiming either a lack of information about the 2x1MB
parts or claiming AMD employees were told to disregard 2x1MB cache desktop parts for the time being.
While distributors could not tell
exactly the reason for the reduction, the cost of running two separate cores and logistics for those cores is obviously eating at the bottom line for AMD. The additional cache per chip means fewer chips per wafers and the additional SKUs means that more marketing dollars must be spent -- and when battling it out with Intel on the pricing front, every dollar counts.
Furthermore, AMD can dedicate all of its fab resources to work on a unified design rather than splitting development between two separate cache revisions. AMD's Turion X2 lineup does not contain any 2x1MB L2 cache components.

seems to have also confirmed that the 2x1MB chips are toast.

Not sure about that. I remimber reading that in AMD's case with at least the L1 cache, that a smaller size is actually better and larger sizes slow down the processor. This could be the case with the L2 however I doubt it.
They didn't say they were eleminating these processors, just down playing them because of the manufacturing cost. So for the hardcore - the ones who will be looking for them, they'll find them.

I don't buy that. The 4200+ and 4400+ are the same clock speed, the cache size difference is where the higher performance rating comes from.
I would prefer the 4400+ with 1MB caches to a 4600+ with 512k caches. But it's all a matter of opinion. Some people say that you can get a better overclock out of the 512k cache because it will generate less heat. It's my opinion that the overall performance will be better with the 1MB caches even if you can't get quite as high of a clock speed.

The larger the cache, the harder and more expensive it is to keep it going fast. L2 caches for the A64 are (I believe) the same speeds, so there was no performance downside. However, you could see this affect in Intels transition from Northwood to Prescott P4's. The Prescott doubled the L2 cache but made it slower as well which caused some applications to gain speed and others to slow down.
