"You can't say that AMD is ever boring. The company says its
next-generation Bulldozer CPU core will take a unique approach to
computing that goes beyond Hyper-Threading, which some believe
could offer phenomenal performance.
"Bulldozer makes a fairly big break from how today's multicores
are constructed. Today's dual-, quad-, and hexa-cores are based on
single-cores strung together. They can share L2 or L3 cache, but
generally are partitioned off from each other. With Bulldozer, the
basic building block of a multi-core chip changes from a walled off
single core to more of a duplex. Two cores are tightly intertwined
and share fetch, decode, floating-point scheduler, and dual 128-bit
fused-multiply-accumulate units, or FPUs. AMD says each module
includes dedicated integer schedulers, pipelines, and L1
cache."
