Usput su se raspričali o Fusion proizvodima i kud sve to vodi.

• If you look at the very high level, people automatically confuse that this is a simple integration of a CPU and a GPU into a single piece of silicon. This is not the case. What we are doing is we are adding parallel computing unit and additional fixed-function units into the mix for the APU. We are also adding new program paradigm with OpenCL and DirectCompute. There are natural hardware challenges. We do have to innovate two physically different devices, glue them alltogether and make sure they work with new protocols like OpenCL.
  
  
• We would view Fusion as not only products but we need to plan our architecture for the current generation and two-three generations down the road. This does take time and it will see our products take big steps along the way in innovation. We need to make sure they are forward and backward compatible and that takes some time. With Zacate we are looking at over 90GFLOPS, which is pretty impressive for a chip of that thermal design power and size. Certain performance goals were not a major a priority.
  
  
• Ontario and Zacate have single-channel DDR3 memory controller. For Ontario/Zacate we are adding PC3-10600 (DDR3 1333MHz) support, it is a fairly robust memory controller and for the vast majority of applications we see no problems in going single channel. If you look at Llano, then memory controller is quite different to Ontario/Zacate. We have also done some tweaks for GPU in Llano. We try to design the best memory controller we can for each of our products. That is all we can share at this time.
  
  
• When we integrated our discrete-level GPUs into APUs, we took the best what we had to offer from our graphics processing units, so, fundamental architecture and cache architecture are the same as in the standalone family. It really does not make sense for use to start reinventing the cache for our built-in GPUs because quite frankly our GPUs are world-class and that is not something we need to innovate.
