| JRPGfan said: Its weird that AMD has done so well with setting the standarts for ram. They worked on DDR ram, back when Intel wanted everyone to use RDRAM from rambus. They helped develope (I think) the GDDR ram that graphics cards use. Now theyre helping again with thew new ram technology. I hope it goes well, and I hope we see it used soon for APUs and motherboards. Let DDR4 go away and lets get this new stuff instead. |
On APUs, unless used as a Last Level Cache mainly for the GPU (basically a on-package VRam), HMC would be more useful as the link on HMC goes both ways simultanously, while HBM would force the CPU to wait several clocks before the registers could be accessed again.
Also, both are problematic when it comes to expand memory, as classical RAM-dimms won't work with any of them afaik. If you need more memory then what comes delivered with an APU/iGPU, DDR4 is still the only viable way to go.
