The two main things BD is sharing is the L2 cache and the front end. Thuban has 6x128bit FP units and BD will have 8x128bit FP units (which can combine into 4x256bit units for software that takes advantage of AVX). Thuban has 6 integer "cores" made up of 3 pipelines and BD will have 8 integer "cores" made of up of 4 pipelines.
Furthermore, even when the L2 cache is shared (only when both cores in a module are active) there is still 1MB of L2 cache per core whereas Thurban has 512Kb per core. The L3 cache is 1Mb per core on both CPUs. Please do some research before posting misleading information.
Bulldozer will NOT be slower than Phenom II which is what these ES benchmarks make it out to be.Edited by JCPUser - 6/10/11 at 1:22am
