kaveri hsa improvements

Why not link to a place that has atleast 1 benchmark with HSA in it?

Not sure how much software is currently out there that makes use of HSA, but its bound to grow with time.
 
The GPU does some workloads really well, but others really badly.
The CPU does some workloads really well, but others not as good as a GPU does.

HSA is breaking down code, so your GPU does 1 part (the stuff it does well), and your CPU does the rest (what your GPU doesnt do well). They are working together.

This makes it much faster than just useing your CPU for everything, or just useing your GPU (opencl) for everything.

You make the parts of your hardware best suited for work, do the work they do best.



Look at that "Libra Office" excel workload.
Its probably not the "best" show case of how HSA can work, but look at the speed up in performance.

only 86x = 2418 ms.
HSA = 482 ms.

thats like 1/5th of the time, it takes to do it with the cpu.
A 5x performance boost.

In that benchmark the HSA A10-7850k is beating a Intel i5 - 4670k by like 300% in performance.



do you think with hsa code that was written good that the a10-7850 would be more powerful than a 8350

Without a doubt, a A10-7850k with HSA will beat a 8350.
 
What is that jpeg decoder? Does that mean if I have a folder with 1000 huge jpegs, I will be able to browse through them even faster? Sometimes it is really annoying having to wait 200-500 mS for it to display each image, especially when you have hundreds to look through.

I dont know to the answer to your question, but on one of amd's hsa demo video they did show how hsa speeds up loading of several pages of jpeg preview pictures.

Yes. But you must use the latest Catalyst driver. The 14.2 beta will install the HSA decoder on Windows 8.1.
