I wonder if an entry level GPU in that form factor would be a lot cheaper than a regular budget card? Entry level GPU's cost way too much for what they are
Would be quite something if AMD could utilize a infinity cache based GPU chip in this form factor. Plus there is also 3D NAND, direct storage API, and StoreMi. Finally there is SAM with BAR size and PCIE isn't exactly standing still not to mention you could just as easily take this concept and re-purpose it for PCIE x2/x4 wired M.2 devices to top it all off. The other aspect is you could even crossfire them not that I think it would make a great deal of sense you'd probably as well off not doing so and have each with a single output handling their own displays up to 3 would be pretty trivial given a lot of boards already have that many M.2 slots. I think a few of this to add additional displays while offering some upscale and post process assistance potential to a discrete GPU would be a nice thing to consider as well.
I think even Direct X 12 might make that more usable and useful for that matter the infinity cache would be combined would it not I mean that was suppose to be a perk to mGPU for DX12. I think in the case of a triple display setup with a discrete GPU and 3 of these each of these could handle a display and do a bit of upscale while the discrete GPU renders the entire scene and splits it among the 3 M.2 GPU's to displays like SoftTH. If you had 4 they could easy handle a quadrant. to upscale and post process within a certain threshold. The GPU chips on the M.2 would obviously be small die sizes as well so the yields could be good too. It's defiantly entirely possible to do iGPU upscale of discrete graphics even now and post process should certainly be possible too seeing as the mClassic is capable of it. They would be pretty nifty with a touch of co-processor tech capabilities bundled into each.
AMD could even have 3 of these wired to the discrete GPU's and do away with the additional HDMI/display ports in practice and just add one of these types of devices for additional displays that can also do a bit of upscale and post process. The aspect is if you had a 4K display with 4 inputs that can do PIP/PBP of whatever type and 4 outputs say 3 of these and the discrete graphics itself and all had some upscale/post process they could perform on each output that could be rad. I suppose Intel/Nvidia could certainly do these things mentioned as well for that matter, but infinity cache adds a layer of interest to the whole notion of these compact all in one single display GPU's in regard to performance potential.
