AMD' s New Trinity APUs: Anyone using one?
Howdy,
After searching around many of the hardware sites and Linux sites out there, I wasn't able to find anyone talking about using AMD's new APUs under Linux, so I figured I'd finally make an account and start a conversation! (I'm a very long time reader lol...). I am curious to know if anyone is playing around with OpenCL for general computing and how the graphics driver support is for AMD these days. Also, are there any optimizations that take into account the single shared floating point unit between two "cores"? I'm personally still using a Core2 Q8200 and Nvidia GTS450 video card as my main computer, which I am happy with, so I can't personally make use of OpenCL. However, AMD's "heterogeneous computing" concept seems like a really smart way to bring excellent application performance on modest, well balanced hardware. From the benchmarks that I have seen on the web, Handbrake and Winzip OpenCL performance on the A10-5800K APU is very good, which makes me wonder what magic the minds in the Linux community can work with it. Have any thoughts to share? |

Outside of the 'obscure app division', there is one intra-app case that is interesting and that concerns games, and there I have to admit that I just don't know, but much magic happens there. Outside of games and the 'obscure' stuff, fp-heavy isn't common anyway, so maybe it is being treated as a non problem. Except for compute servers? Quote:

Get a FX-4XXX (or better) and a video card, or an intel. Its only a tiny amount more than buying a A10-5880K, is more upgradable, more flexable, and you arent buying a GPU on a CPU that probably wont have enough guts to play the games that you bougth the GTS450 to play (the HD 7660D in the A10 has less power than a GTS450, and even a $70 HD 6670 will easily outrun the HD 7660D) There is a test at Phoronix- http://www.phoronix.com/scan.php?pag...0k_linux&num=1 Not that Phoronix has the reputation it used to. |
There are a number of people using Llano and Trinity under Linux with no problems, though I agree not much onlien chatter about it. I have an A10-5800K siting on the desk here that I won that will likely find its way into a media machine or perhaps a small home server.
As the centre of a low power general use machine I think they'de do fine for most things. Intensive computer or graphics requirements would be better served with other processors and GPU's - but of course that's not the niche the AMD APU's are aimed at. |
Thanks for pointing that out about OpenCL, Cascade9. I had not looked into it, assuming it special hardware level support, but it does work on Nvidia's CUDA GPUs with recent drivers. Nifty (and handy for me).
I feel kind of bad for AMD, in that they are willing to innovate with OpenCL, but Intel and Nvidia are right there doing it too. Apart from good value for the dollar on the +/- $100 cpu market, they just don't have much to offer anymore. I was hoping that OpenCL would give them a bit of a leg up if folks got on board to program for it, but I have the feeling the end result is that it will just end up working better on Nvidia video cards with Intel cpus. Poor AMD... Still, it would be neat to see some useful apps, like GIMP, get some speed boosts when an AMD APU is available. May as well use those resources if they are there, right? :) |

AMD still holds down Intel CPU prices, and even if thats all they had to offer its still A Good Thing. ;) Quote:
