On a sidenote, I know how a lot of people mention the next-gen consoles are underpowered, but I rather doubt any of them have even given the HSA capabilities any more than a passing glance. If you've seen just what sort of performance improvements are possible with it, your mind will be blown.

Mantle for the PC improves performance just by removing overhead, letting it perform like a console, but otherwise whatever power is in the GPU is what you get to play with. With HSA, the raw power you have access to simply multiplies. Libreoffice, while not being a game, shows just how massively a purely GPU operation (running on OpenCL) speeds up if HSA is leveraged. Check out the main thread here on HSA, but LO received something like a 400% boost in calculation speed.

So yeah. Next-gen console performance will get better despite being built on familiar and apparently mid-end hardware. Based on the few real world HSA workloads benchmarked so far, better by a lot. And the best part is that this is tech that's coming to PC's too, starting with AMD's APUs like Kaveri, and hopefully continuing with their hardware and software partners.

There are a few problems with that. For one it would take away resources that could otherwise be used for rendering. And you're assuming that HSA development tools will even be usable with whatever Sony and Microsoft implemented on their consoles. As far as we know neither implements HSA according to AMD's specs, only something similar to HSA.

This makes a lot of sense! Duh! I was wondering why the Xbox 360 emulator Dev mentioned Mantle... LOL

I look forward to this, I want my obscure Macross and Gundam games. biggrin.gif

Well maybe in 10 years from now we might actually be able to play Uncharted in 1080p....

Whoa. This is MUCH faster than anticipated. I mean... it was years before we saw bug-ridden 20-30fps footage of PS2 games with PCSX2... Dolphin's development pipeline was the fastest of any Emulator to date, and this is picking up speed rather nicely. Showing 2d animation at the level in the videos shows immense progress. It's hard to put into words how big of a step forward that is, especially since its also running commercial code. And it's doing it all at a decent speed, already... That said, there is still a lot of work ahead of that team... accuracy is way off from the looks of it (some of it is texture decompression issues, some of it is probably floating point accuracy issues) Luckily we're smart enough now to skip the whole call translating system and go straight to a Dynarec/VM for emulation. Virtualization features and already available VMs for same-architecture processors is going to make development slightly less of a chore, but implementing all those SCE calls is inevitably going to be a huge nightmare... though they have at least a decent percentage of that knocked out already. Wonder if they had someone donate a dev kit to help speed things along...

this is awesome. so many PS3 classics i would love to be able to play years later without having to dig out an old console from somewhere.

Amazing. Did not expect to see such progress this soon.

Why is it hard to put in words how huge this step in ps3 emulation is?

I do want to read how exactly they pulled it off. The Cell architecture is such a strange beast that I don't know how its possible to emulate to x86. Do they run the individual SPEs on each x86 cores? Is a 3930k or even a haswell-e even enough?

None of those are real problems what is the problem is that HSA is great for floating points but won't yield the 50x speedup in integer and until they scale it up like what they did with moonshot it is trumped by e5's.

I think even without the millions of optimizations this still needs if it could be scaled over unlimited core I would be able to run this. (with 120 ivy cores)

We all know that this development will take ages before we can expect good frame-rates. If a game with simple graphics such as shown in their latest video barely runs let alone the games like GTA V, The Last of Us, etc. Right now, buying a cheap PS3 is a wise decision instead of waiting for a proper emulator.

Anyway, props to whoever made this possible and I'm looking forward to more updates in the future.
