AMD cuts to the core with 'Bulldozer' Opterons

[Florinmocanu]

even with 32nm, the BD core is not small though.

Shanghai / Deneb single core: ~19mm^2 / 55M transistor
Calculated BD module: ~29mm^2 / 165M transistor (assuming 50% die shrink, ~150% die size claimed from AT's communication with AMD)

Packing 4 modules with 8MB L3 cache, you still get about 180mm^2 die size.

1 BD module = 2 Deneb cores.


So, 165 M vs 110 M for 2 deneb cores, 29mm vs 38mm. Performance should be higher as well, so i think they are doing a good job.
