Hi everyone,
i'm going to buy an APU (AMD A8-6600K). This cpu have an GPU within (HD 8570D).

Can i use BOINC with CPU and his GPU both? I know that the GPU doesn't have much power, but what do you think about? is it a good idea?

Thx, and sorry for my bad english!

more slow than the cpu itself?

i've always knew that gpu>>>cpu with boinc...

i think, even it's half than cpu, it's better than nothing, isn'it?

You can test it with a GPU project. But its better to use a GTX660 or a comparable card.

Actually, yes. The CPU has as a quad core, 4 OpenCL compute units. The APU has only got 2.

As a comparison, my Radeon HD7870 GPU has 20 OpenCL compute units. The GTX660 that Rebirther points out will have between 15 and 21, depending on which version one has.

The new AMD APUs and other SOCs are certainly more economical than a dedicated GPU, from a consumer standpoint, which is why I assume they're showing up in a lot of low-end devices. As I'm not terribly familiar with their construction, does using the GPU provide any slowdown to the CPU (or vice-versa) or are you simply making a comparison between the APU's GPU performance versus a dedicated GPU?

I don't have one myself, but one of my team members does. However, it doesn't get much crunching done because most of the time it is used on battery.

uhm... i see. :(

so, more or less, is about 50% slower than the cpu...

P.S: i'm sorry but i didn't find multiquote option.. :(

I will add a stand alone video card (ati hd7950), but i however want to use my APU's GPU.

I just wanted to know how powerfull was it... :)

Anyways, can you ask your teammate how much crunching he can do with apu's gpu in 24 hours?

WCG does not have any GPU sub projects at this time. According to the community advisors and admins, there isn't any projects in the pipeline any time soon that will use them either. Check the forums at WCG regularly for updates.

i add at my pc an ATI hd7950. Is there any way to make BOINC use both gpus?

Now it see only my 7950 and not my integrated gpu...is there something i can do?

Thanks!

You need to create a cc_config.xml if you have not and add the line

<cc_config>
<options>
<use_all_GPUs>
</options>
</cc_config>

to it.

It always helps to give questioners a link to the documentation, and sometimes to refer to it yourself. You need a closing tag too, as shown.

wonderfull! thank you so much!!

i suppose that it's even possible to set the integrated gpu to be used by boinc!

I'll make some test! thanks!
