My System Specs

Default So that new AMD APU with HSA 1.0 seems interesting...

SOURCE: AMD :: Investor Relations :: News Release

Ok so AMD unveiled their new APU called Carizzo and Carizzo-L which sounds like a typical average APU but apparently it's the first version with HSA compliant specs in it.

The CPU is powered by the Excavator micro-architecture and the "next generation" Radeon GPU architecture.

These APUs are mobile only however.... I would love to see the difference with a program that's HSA compliant and the same program not running in HSA compliant.

So what do you guys think?

Kaveri was supposed to have HSA, I'm guessing the bugs in it was never worked out.

It has `HSA features` not all of them, just some!

the next step will be having the cpu/gpu being designed as one unit from the get go. Years ago they did programmable shaders that could be vertex or pixel as the devs seen fit, so a cpu that has cpu blocks and gpu blocks may take that route as well being able to have the cpu "cores" able to be gpu cores as well and so forth. HSA will be a backbone for many things mark my words.

Like what I am hearing so far. Would raise the bar for lower end mobile/laptops.

Fool me once, shame on you.
Fool me twice, shame on me.

Again, you can throw all the features you want at an architecture but without massive investment in developer support, it won't amount to anything. Why should a developer invest their money and bandwidth in HSA feature development when Intel can turn around and say "hey, look at our ridiculous x86 performance advantage, you can code like you always have!"?

That's the argument that AMD is still loosing in the development community. It happened on the GPU side with Bullet, Raptr, their stereo 3D initiative, etc. etc. Sadly, if you don't throw money at the situation or develop your own closed and controlled ecosystem (see 3D Vision, CUDA, GeForce Experience, WiDi, AES, VT-x and so on) then the development world is likely to ignore you. That's what happened with Kaveri and may happen with the next generation parts as well.
