And I still don't see a GPU-Z validation link among my search.
And on the description it shows 3 GPUs under crossfire, which means beside APU and 7700 series there is another GPU.
For simplicity sake let's assume 2 x 7750, is it even possible to do iGPU + 2 x 7750? Pretty sure hybird corssfire only covers to 1 iGPU + 1 dGPU.
as far as i know that still isnt possible, but it's possible it's a glich here... unfortunately of the reports of successful attempts this is the only one that had a video that i know about. Though when looking around there were several reports and 1 from someone who saw the claims and tried it for themselves. there is not much on it because amd has yet to announce anything about it, and people are assuming the hybrid crossfire is the same as it always was. Im guessing this is just a workaround amd found and it wont perform as well as the normal hybrids when it comes to scaling, but the timings for these are not surprising given that the drivers in question are going to be the standard drivers upon the release of richland(estimated june)...
if you cant believe it you can try it for yourself, but i have yet to see anyone who tried it recently(with beta drivers) say it doesnt work. just a lot of people stating that you cant crossfire with the 7000 series.... and to be entirely fair the only reason i looked around so much is because when i first saw it i thought it was a hoax :|. though since the results from everyone who had tried it recently appear to be unanimous, i decided to just consider it as preparation for richland and wait until that to find out exactly how it happened.
and about the apus being bad for gaming, again im using a mobile llano processor, and while i have to tweak it around a bit, i've been able to play pcsx2 using it and its igpu. the later editions of the apu support instruction sets that llano do not that make the emulation easier, and have a general increase of performance in both graphics and processing.... add in that on the desktop version you can clock it to almost 5ghz(twice my clock rate) if you have decent cooling. and that means you could pretty much triple my apus performance using an a10..... plus kaveri is supposed to be a massive step up, and even feature 6 core processors(which while the emulators wont use all the cores, it will leave more room for the gpu to work). As far as i see if you are willing to work with it apus are completely viable for emulation.....
and actually not seeing what the person im replying to was talking about with 2gpus the only thing in the description is a comparison of the 7750 not in dual graphics, the 7750 in dual graphics, and the 7750 paired with an i5.... adn other than that they just mention the integrated graphics(think its 7660 or something with this gen but i forget) and the sapphire 7750
also in video comments someone was saying they were able to do the same using an a8 trinity when they used the 13.4 catalyst drivers. again im not suggesting this as a viable option, tbh the a10 and the a8 igpus dont have much power compared to a 7750 and the scaling seems pretty bad atm
Last time I check you CANNOT crossfire 7750 with an APU.
Both Trinity and Richland are using VLIW4 from HD6000 series. HD7700+ series is using GCN instead. It is impossible to do crossfire on between VLIW4 and GCN together.
You have to wait for Kaveri (by then it will only crossfire with HD8000 series). In any case crossfire introduces too many problems that on low end GPU such as APU it is not worth it. Not to mentioned that emulators such as PCSX2 will never take advantage of crossfire.
Both SLI and Crossfire will only work on games that have respective profiles built into the driver, for those that don't your second GPU will be on idle during gaming.
and addressing this one directly. i've yet to be able to test the results of the crossfire 7750 myself, but there have been reports about it ever since people first started trying the 13.4 drivers. As for the crossfire you would be surprised about how well amd does with the dual graphics. i thought it would have hiccups as well but the amount of times i ran into anything like screen tearing and fps drops were very very rare. im not saying they dont exist, but they happen much less frequently with apus than most seem to believe.... and im on outdated hardware so they probably happen even less now. It's hard to believe when talking about a company thats almost famous for f'ing up its drivers, but the apu doesnt seem to run into compatibility errors. also with the new drivers pretty much any dx9, 10, or 11 game will run with dual graphics... you may encounter some that dont run well, and even an extremely rare case where the performance decreases), but speaking from experience for the most part you will see a pretty standard boost to your gaming
as for emulators utilizing it.... that may be but that's pretty irrelevant since pretty much any gpu on the market can handle an emulator..... like i was saying the a6-3420m im using(a llano, and not even the highest igpu of the bunch) handles what pcsx2 throws at it, so dual graphics isnt anything you even need to consider there..... and as far as i know no emulator around right now is intensive on the graphics side of things.

there is something covering richland(mobile versions, but it's still a crossfire across different architectures) , but as for the specifics of how it was actually accomplished the details arent really there.... anyway since they are the same architecture it's assumed trinitys abilities to crossfire with the 7750 are due to whatever they did for the richland,
also while i vouch for their current dual graphics, i really dont know how well whatever they did will workout... half because i dont have the specifics of it... and half because i still wouldnt understand it XD
it should also be mentioned that although it is apparently running with the a10s... it probably wouldnt be recommended to build based on it..... it would overall most likely have a lot of shortcomings... kinda like crossfiring the a6 with a 6670.
