I think Zambezi is an 8 core CPU but something comes to mind and, if possible, Iīd like to know how both Intelīs Sandy Bringe (2600k) and AMDīs Bulldozer (Zambezi) would behave if they have to handlle more than four 256bits instructions at the same time (is it even possible?).

Edit: 4 x 256bit floating point instructions

Thanks.
same as any other operand. If it cannot be sheduled at the same cycle it will be sheduled the next cycle.

So if cpu 1 needs 6cycles for one AVX instruction it will need 7cycles to do 2 AVX ops


Also with FMAC BD can do 8. SB can do 12 if they are different types but that rate is not sustainable.
