So what happens to the laptop market if intel pairs an amd chip to ALL high end laptop parts? The way I see it intel is taking a jab at nvidia with this amd deal and if they really want it to sting then why not pair an amd chip to the entire high end line? A few things could happen
Current gen 15 inch macbook pros have a 45 watt intel chip and a polaris chip. This seems like a size reduction on the pair at least and maybe some power savings to boot. I'm curious if there will be a lower wattage version made as well.
Intel does on package dram so.... memory access might be there. On CUs you've got a point, but even a 7850k with a better memory system is at least interesting and with updated cores it might even be compelling.
AMD wouldn't kill raven's ridge, but they would kill a good deal of laptops with geforces. Intel still commands the high end market, and a quad core intel chip with mid range vega sounds like a discrete gpu killer to me.
Anything pre-maxwell from nvidia or pre-vega gcn on amd should work with open drivers. Not sure what chip the 710 has in it, but if it's kepler that might be the card to get. AMD wise it looks like the r7 240 is the cheapest thing, but it's 3x the price of the 710 so.... ya.
