Deneb 0MB L3 doesn?t have L3 cache disabled


Secret weapon

We learned that Deneb, the 45nm CPU from the Stars generation with zero L3 cache, is going to be a native part. This means that Deneb without L3 cache simply won’t have the L3 cache disabled, it will be produced without it.

AMD plans to produce two versions of the chip and Deneb 6MB L3 will have the cache on the chip while Deneb 0 MB L3 version won't have the L3 cache disabled; AMD will manufacture this chip without L3 cache.

We can tell that 6MB of L3 cache takes a lot of space and it is likely that Deneb 0MB L3 is going to be AMD’s secret weapon that might lead to company’s recovery. This can easily be the smallest or among the smallest quad-core chips on the market, and we believe it will be massively smaller than Intel's Nehalem part.

A smaller core usually means better thermals and cheaper production. Our sources also added that the performance effect on the desktop CPUs without L3 is very small, so there is no big performance penalty, at least in the real world, but some benchmarks will suffer from it.
