i been reading fair bit about this HSA and hUMA, but what i don't understand is how will this effect top end market? will discrete GPU's even be able use such tech?

AMD say's its Open source , so does it have be a APU for HSA and hUMA to work? and what about Intel and NV? and what about Intel CPU with AMD GPU's? i'm not even sure what make of this tech, i seem's like to me it would require a extreme over haul on how motherboards are build, and if discrete is use with the tech i'm thinking they need to move location on were PCI lands are to be far closer to CPU to access the vram as efficient as APU, i don't know though it would seem like if this take's off , desktop PC as we know it will no longer be remotely same as current stuff we have, just whole motherboard designs will be dramatically different. i would think so, i could be way off, man i don't even know if discrete GPU are even viable for this tech. can anyone bring some light into this subject

Edit: PS4 and Xbox one use this tech so i also want to know what impact will that have if it takes off, and what will performance be like if so?

Your question is very complicated and so is the answer. To explain HSA is a system where the GPU performs FPU tasks(the GPU is basically a large FPU) and the CPU performs other tasks. In other words, the GPU and CPU work together instead of separately. This is achieved partly through Huma, where the CPU and GPU completely share memory. The technology is open source. So theoretically Intel could use it, but they are not a partner of the HSA foundation, started by AMD. ARM, however, is a partner along with Qualcomm and Samsung, among others. Microsoft is also said to be a silent partner in HSA. For this reason the only x86 components to use HSA will be AMD, because Intel wont and Nvidia can't(no CPU). It is theoretically compatible with...

It is theoretically compatible with discreet GPUs, but it is unknown how or if Huma will play a part in this. With proper implementation and coding, HSA could revolutionize compute by removing the need for a CPU-only part. It would make APUs much more power efficient, smaller and much more powerful. It would also put Intel at a serious disadvantage if it takes off. The first HSA parts will be Kaveri shipping to OEMs in Q4 and consumers in Q1 2014. Motherboard designs per-se will not change much. The first HSA capable MBs are already shipping with FM2+. I think the consoles could help the adaption of coding for HSA and could seriously help AMD's HSA push. I hope this helps and feel free to ask any questions in case I left stuff out!
