Intel has been trying to do it since years, but they have failed in a an ugly fashion with poor graphics performance of Core i3, Core i5. Not just that, Intel has failed at even creating a decent dedicated Graphics processor. Now AMD, with years of strong Graphics processor ATI, seems to be holding strong with Fusion of CPU + GPU.
AMD Fusion was planned for 2011, but as per today’s announcement, they seem pretty confident that they would be able to deliver Fusion products to system builders within this year. No doubt, AMD has been talking about Fusion for years, and Intel has already taken the lead (only in time) to AMD by launching its Clarkdale Core i3 and Core i5 CPUs with integrated graphics, even though these use separate CPU and GPU dies combined in a single CPU package.
AMD however, is determined to combine everything into one piece of silicon that does both General purpose CPU and Graphics. On being asked, How well is this going to be, AMD’s representative Bob Grim replies:
“I don’t think there’s a simple answer to that, if you look at the history of AMD, when we came out with dual-core processors, we built a true dual-core processor. When we came out with quad-cores, we built a true quad-core processor. What our competitors did was an MCM solution – taking two chips and gluing them together.
There was a fair bit of engineering work involved too, but we just have a tradition of building a piece of silicon from the ground up, in fact the only MCM (Multi-Chip Module) solution I’m aware of that we’ve ever done is on the server side with our 12-core product (the Opteron 6174). [Regardless], what we’ll be launching with Fusion is definitely all on one die.”
AMD believes (and which is logically true) that building a CPU/GPU hybrid chip on a single piece of silicon would yield significant speed advantages if not Tremendous. Apart from that, it should have power and performance advantages because it is done with latest 32nm manufacturing process. The Future is Fusion.
