    Doesn't the on-die GPU take up quite a bit of die space, though? Why not put say two extra CPU cores, or bigger cores on the die instead. Enthusiasts don't need the on-die GPU, do they?

      A little questions, has AMD abandoned the high end CPU market? No future high end, high performace CPU for the enthusiast market? Or the future for AMD is an high end - high performance APU paired with a high end GPU for the enthusiast - gamer market? Will be an APU with HSA direct rival for Intel core i7 for example?
      AMD's new SMT architecture is in the works for a 2015 release. It is said to be performance oriented.
      Considering this is the first processor to be completely designed around RCM it should be very good. Especially when AMD has Jim Keller at the wheels.

        I'm guessing it's easier and cheaper to pack GPU shaders than extra cores, as in a CPU packed full of cores is more expensive than a CPU+GPU sharing the same die space. Theoretically they could probably release a 16 core FX right now though.

          I also realised they want stuff like floating point to be done on the GPU, which is only a realistic goal if all CPUs have on-die GPUs.

            Theoretically, i'd be happy with a 6-module (12 core) FX @ 4.5GHz.

            To be honest, i'm quite pleased with my FX-8350, i'd like to see the FX series get a bit better, even if that would mean a new non backwards-compatible socket (AM4 or something).

              amd need

              amd need to improve the single core performance a lot and not put more and more cores in their cpu, why is the point of a 16 core cpu if apps use no more than 6/8?

                Look at the Opterons, there are some 16 Core CPUs. They have 2 DIEs on the same Package.

                  And just what real world application do you need more single thread performance for as opposed to more cores?
                  Games? Nope, Core 2s are fine in terms of single thread performance for most games
                  Compiling? There's a lot more to be gained by going parallel
                  Spreadsheets? Nope
                  Video Encode/Decode? That's offloaded to the GPU

                    Every Application profits from a higher single thread performance.

                    benchmarks call you a liar.

                    Like the first but compiling is for most users irrelevant like weather calculations.

                    Speadsheets on the gpu are useless. Look at the calculations. You can create a scenario thats runs very nice on the gpu but thats not the case for everything or the most.

                    Decoding (Only for Playback, copy the frames to the system memory kills many benefits) yes but encoding not. The Hardware encoder doesn't provide the quality like a software encoder on the cpu. You can maybe use the ALU of gpu for some parts of the encoding (x264 can do this for some lookahead with opencl) but thats only interesting for HSA.

                      Thanks for the responses!


                      Thanks Bridgman! Interesting readings.
