Not going to pretend to know about GDDR5's conception, but a joint venture isn't the same thing.
HSA doesn't count, making something, having small support and going "Open Standard lads" isn't the same.
Freesync's implementation to me is still the first thing AMD's ever came up with that'll come to true fruition as an open standard that *should* have widespread support, and that's the kicker, the whole widespread support thing.
AMD jointly developed GDDR3 4 and 5, and a joint venture IS the same thing. Groups of people work on things all the time, AMD chose to be part of a group making something that everyone, not just AMD benefits from simple as that.
HSA doesn't count because having small support...... lose.
HSA foundation includes the massive majority of the chip producing industry, Nvidia/Intel are the only notable absentee's.
AMD, ARM(you know the biggest selling ISA), Imagination, mediatek, Qualcomm, Samsung, TI.
Contributors, Sony, Via, ubuntu, vivante, broadcom, oracle, tensilica, st, marvell. A lot of those looking to support and move software stacks towards HSA support, with Java being under a HUGE transition to HSA supported gpu acceleration currently.
HSA is anything but small support.
Freesync is the only thing with widespread support, HSA is going to be one of the biggest game changes in the industry, you may not believe it but come back in 5 years and see how much software you use would support gpu acceleration and run significantly faster on HSA chips. GDDR has widespread support across the industry for high bandwidth applications(mostly graphics).
The existing display port 4k standard is something AMD released.
Display port, on every AMD/Nvidia GPU, most monitors, all Nvidia g-sync monitors..... AMD came up with it, and continues to improve the standards and come up with improved usage of display port, making a Thunderbolt alternative that is basically free and better in some ways, worse in others, much better overall.
AMD has done nothing at all...... unless, you know, you actually know what you're talking about.
4k @ 60hz down one cable, thank AMD for that, multiple(maybe the majority) of display port features, thank AMD for those. The speed of your current Nvidia gpu and it's gddr5 supported bandwidth, yup, AMD again.
