轉貼AMDzone的文章，AMD有提到將SSE&AVX丟給GPU運算的計畫，還不確定會在Bulldozer上實作?!
- Bulldozer will have improved single-thread performance than today's processors
- He seems to imply that at some point SIMD instructions may be offload to GPU, but it'll be the (post-2011) future era
- Larger cache, higher memory integration (stacked memory) are being considered for the future era
- Each Bulldozer module is an optimized dual core
- Each Bulldozer "core" is capable of 2 loads/cycle; each is a 4-way out-of-order machine
- Bulldozer module is not bigger in area than Intel's hyperthreading design
- Bulldozer module can achieve ~80% speedup when running 2 threads (versus ~25% from hyperthreading)
- Multiple Bulldozer modules can share the L2 cache; and multiple of those (module? L2?) can share the L3 and NB
- Each INT scheduler can issue 4 inst./cycle; the FP scheduler can issue 4 inst./cycle
- "Over time" a Bulldozer "core" (INT only?) can be deployed in APU to work with GPGPU (for FP?)
