AMD’s APU project has really progressed over the past year. Ideally we would like an APU to be a 50/50 distribution of CPU and GPU Power. AMD’s upcoming Kaveri APU is the closest thing to it with 47% of it being made up of the GPU. Below you can see a comparison between AMD’s Kaveri and Intel’s Sandy Bridge, Ivy Bridge and Haswell architecture.
As you can see Kaveri has the most GPU power in their APU compared to Intel’s processors, although Intel’s CPU to GPU ratio has increased over the past couple of years. Kaveri really shows how far APUs have come and to add to that Kaveri is the first heterogeneous APU. Below is a comparison of the architectural different between Llano, Trinity and Kaveri.
As you can see Architecture-wise Kaveri has undergone major changes.
