[PCPer] AMD Fusion System Architecture Overview - Southern Isle GPUs and Beyond - Page 4

post #31 of 47
I want a GPU that runs at 3Ghz core clock and does all the things a CPU does.

Kinda looks interesting. I definitely cannot convince myself to go from 5xxx series to 6xxx series, hopefully they bring it this time with some really nice new features.

Neat.. Looking foward to them, and they launch this year too.

Cayman can't compete with Fermi except in "simple" GPGPU applications like brute force password cracking. Anything more advanced and NVIDIA has a huge lead especially with the language.
So then I'm not sure I've read where they want to fit in GPU computing for the desktop other than gaming. Maybe I did read it and misunderstood it.
In what application (other than random hashing) is AMD and Nvidia hoping to apply this? And is Microsoft willing to play ball, or is it more individual programs?


Bitcoin mining also pulls ahead with AMD, but that's because the computations are very similar to brute force password cracking.

Take a look at this link for hardware hash rates for various video cards.

[...]

Nvidia pushed Fermi computing to compete in HPC market and as a result they grabbed some market share there with all the supercomputers and computing centers being build of Teslas, plus the professional app market with 3DSmax, various CAD apps and other math/engineering software being significantly accelerated by Quadro cards.

With every year those markets tend to use more and more GPUs computing capabilities instead of going the traditional CPU heavy solutions and that where Nvidia is putting their money on and continuously increase their presence.

As far as the typical desktop usage apps and their support, it's more of a bonus by using the capable hardware (GPU) to help with everyday stuff, certainly not the focus of either of companies. Tho with each day how we increase the number of CPU+GPU combos that are likely to be a standard in the future, so the audience grow as do the opportunities.

AMD is seeing the big picture now and they want to get the piece of pie hence the new arch direction.

As far as all the people comparing theoretical performance advantage of AMD cards over Nvidia's offering. In a real world heavy computing scenario AMD cards have significantly lower efficiency due to the arch not being tailored to computing, but rather to gaming, hence the real word performance is nowhere near that of Fermi. Anand went quite in-depth on it, so read it up.

It would be terribly huge, terribly power hungry, terribly inefficient and terribly expensive.

BTW, innovation is something AMD knows very well how to do, and I love innovation

So, if it's a tradeoff between gaming and computing performance... I'd say, screw VLIW. GPGPU is more powerful than GPU alone.

Awwwwww

I like the idea of upgrading your GPU(+CPU) like a graphics card.

Pop it in a PCIE slot and you've got yourself a card that's 10-30% better than the previous gen,
including your on card CPU !

Are you always this stuck up?

But along with the new architecture GCN will bring with it a number of new compute features to further flesh out AMD’s GPU computing capabilities and to cement the GPU’s position as the CPU’s partner...


Judging by how they're pushing their APUs, I'm willing to bet their future GPUs will have AMD-only acceleration features that will work better with an AMD CPU, which is what I've read in other smaller (read: more straightforward) articles before. Don't expect me or anyone else to read through all of that jargon though, as I'm not planning on re-designing their architecture...

If you've already got a GPU sitting around, with a ton of unused power, why wouldn't you tap into it? Why buy another piece of silicon?
