Yo me acuerdo del Celeron Mendocino que tenÃa 128KB de L2
Very Interesting about add L4 caches on Intel CPU. Well we will find out in future. I hope Intel will put L4 caches add on next gen Extreme Edition on Desktop. Who know?
I would be surprised if that shows up for Haswell-E. Remember, Broadwell is the 14nm version, but Haswell-E, which ships next year, is still 22nm. Those chips also have 8 cores already, so integrating a huge EDRAM would be more expensive (relative to die size).
I might expect Intel to integrate the cache into the generation of EE chips after this one.
The rule of thumb is that we gain about one cache level per decade. It's not far off. ;)
CAMPUTER is coming! So long Hard-Drive and SSD!
Uh. Don't think we're anywhere near that point yet. Though it'd be hilarious to put DOS + games on the L4 cache of a chip. ;)
