BD and module concept is good but many thinks need to be tweaked and I think the biggest problem is the cache subsystem and It needs a major change.
I would like to see something like this:
L1: L1I 64KB + 2* L1D 32-64KB.
L2: 512-1024KB per module
L3: 512-1024KB per module
current BD 4module: 4*64KB+8*16KB+4*2048KB+8*1024KB=16768KB
BD 4module version1: 4*64KB+8*64KB+4*2*512KB+8*512KB=9056KB
BD 4module version2: 4*64KB+8*32KB+4*2*256KB+8*256KB=4608KB
This way you save some power consumption along with big die size and the performance doesn't need to decrease by much, actually in BD I wouldn't be surprised if it increased because of Write-back L1 cache and smaller but faster L2 and L3 cache, finally L3 could be working at full speed and not just half.
I love how everyone skips over the fact you got 1/4 size data cache 16Kbytes being 75% as fast as 64kbytes at 100%.
