If so, how does this work with AMD’s upcoming high-end Summit Ridge CPU’s? It is widely accepted that HSA does not deliver on its promise (at least under current architecture) if there is not a tight coupling of the CPU and GPU with a shared memory allocation, and also affected by latency problems with PCIe. Hence, i can buy a £300 laptop which supports HSA, but I cannot build a PC that leverages the power of my £600 graphics card and £300 CPU. Either they sort out this limitation of shared memory pool and latency over PCIe, they stick shaders on Summit Ridge, or, HSA has no part to play in their high-end offerings.
At least that is what I used to think, but perhaps I have been looking through the wrong end of the telescope.
Having just released a lot of architectural information about the Bobcat based netbook APU AMD would appear to be on a roll, so it would be a real downer for them if Intel pre-announced an intention to directly compete in this market segment, however there is more than one Bobcat based APU planned and this blog questions whether Intel is able to challenge both.
With what do they intend to bridge the 5W to 18W divide?
Ever since the October 2007 release of the original Eee PC the world of portable personal computing has been a very different place, it has been a roller-coaster of ups and down as a huge variety of innovative netbook designs were unleashed on the markets, followed by a gradual recognition of all the things they can’t do well, and finally buried by the rise of the (truly) smart-phone. Well now are about to reach another inflection point with the mass arrival of products sporting AMD’s new Fusion APU, and to a much lesser degree the new Atom D510 / Ion2 products.
Perhaps it is time to reinvent the netbook?
