AMD A10 and Hybrid Crossfiire

Hey all, I have been looking at making a mid/low end gaming system for a few friends and came across an APU + Hybrid Crossfire article which drew my attention.

Has anyone had any luck with this setup? I remember once upon a time when you could do hybrid crossfire with the integrated video chip on some AMD based mobos, but that was something to be desired if I remember correctly.

Thanks all!

You can, but it's not particularly good. I think a dedicated GPU and an Athlon is actually cheaper and performs far better. A 750Ti or R7 360 should be ~$130 alongside an ~$80 Athlon, vs $110 for an A10 and $100 for a pretty crap R7 250 at best (and it must be DDR3 to my understanding; GDDR5 versions won't work).

EDIT: Just kidding, apparently it will work up to a 250 regardless of VRAM

R7 is super vague. You have the 240 and 250 using the Oland chipset, 250X using Cape Verde, 260, 260X, and 360 using Bonaire, and the 265 and 370 using Pitcairn. It's just a label that gives a rough indicator of performance.

To put things in perspective, a Kaveri A10 with 512 stream processors can pair with something up to Oland with 384 stream processors. Assuming perfect scaling and disregarding differences in GCN revisions, that's 896 stream processors, equal to an R7 260X. And thanks to the memory type, the 260X has double the bandwidth.

Single GPU is generally the way to go.

You can crossfire either a R7 250 or a R7 240 with either GDDR5 or DDR3 ( you should choose the one with GDDR5 if you ram speed is above 1866 because when useing Hybrid Crossfire ((or Dual Graphics how it's called now)) the GPU's RAM downclocks to your systems RAM speed.)

I had a Gigabyte 2GB GDDR5 and used it in dual graphics mode, you get about double de FPS (~80% more) in the games that it works. The problem is that there are manny games that won't suport it. Also getting a stable overclock on the GPU+iGPU+CPU was interesting to put it one way

I enjoyed it because I like tinkering with PC's but you may not.

So if you can buy the 860K instead of the A10 and with the rest of the money get atleast a 260 (a 260x would be better) you should go for that because it works 100% of the time and you should get the same or prob more FPS.

I think it's just a marketing gimmick. Everyone I've read about who tried it was disappointed. If you like a challenge, or just tinkering, like RaduZ mentioned, might be fun but otherwise...
