FM2 Vram

Quick question everyone is saying that APU's are kinda a questionable choice right now is because to get the most out of your chip you need some decent speeds on your RAM. So the money you'd spend on some good RAM could be spent on a CPU and graphics card that will out perform it. So my question is why don't they just stick some VRAM right next to the APU socket? you can put your power phases to the left of the socket and stick some VRAM to the top or vise versa. Then you can save money on RAM. and I mean 2-3GBs of GDDR5 isnt a lot if you look at how much they cost on graphics cards. So just why isnt this a thing? It would take the performance of APUs to their absolute max for graphics and you can then buy low end 1333 DDR3 memory so then you end up spending a bit more on your MOBOs but you save that money on RAM so effectively you still keep costs down. Your guys's thoughts?

Well, usually the difference between DDR3 1600 and DDR3 2133 is like $5-$10 so it's not like it defeats the savings from an APU.

 

It could be done theoretically, but it would require a new socket and a new standard of memory module, and new APUs with a modified memory controller.

HSA will save problems also hUMA

Alright thanks for the response but do you know any manufacturors that ship 2133 2x2gb memory kits? Cause im looking a bit and I can't find anything below 8gbs that runs at that speed.

a Radeon 7730 with GDDR5 will be faster than APU, anything more and the APU is not 'lagging behind', it completely disappears.. Pair it with a good CPU like Athlon x4 740/750k/760k (FM2) or maybe some Phenom II x4 (which is faster) and a 'good enough' mobo.

Well I know right now APUs get spanked by dedicated graphics i'm just saying if you had GDDR5 right next to the socket what kind of performance it'd get. Cause 2133mhz GDDR3 RAM makes a noticible speed boost. So would much higher clocked GDDR5 make even more of a difference or are the chips designed around having lower speed RAM and if so could they redesign the chips to take advantage of GDDR5 and bring a massive performance spike to their chips?

Maybe. Either AMD is working on it or they already found out that it wasn't worth it.
