will not help chess.

if you find a benchtest where two processors are compared, one with large L1 or
L2 cache, the other with small L1 or L2 cache, the speed is amazing----way above
what we are used to when we think of a certain mhz. When the processor is
filling this on-die cache it can be very fast, but it fills very quick, and then
the speed tapers off to what we consider normal for that mhz. it seems that the
"bottleneck" for todays cpu is the buss and "pipelines" between the on-die
cache, the ram, and the cpu.

Athlon XP model number: 3000+
Cache Size: L1 - 128KB and L2 - 512KB = 640KB Total Cache
Approximate Transistor count: 54.3 million


Athlon XP model number: 2800+
Cache Size: L1 - 128KB and L2 - 256KB = 384KB Total Cache
Transistor count: Approx: 37.6 million

"Sandra 2002's CPU benchmarks have always been popular.  Here we see no
difference in performance due to a larger L2 as was expected".

lots of info on the internet about these benchtests comparing cache.
