There is, but as far as I know Samsung hasn't licensed it to Glo-Flo, nor has Glo-flo attempted their own improvements. They seem far more concentrated on 7nm.There still isn't "14nm+" process and we have no idea how many chances Navi will be bringing
So they've stated multiple times, and that AMD should be among their first customers as they expect AMD to be the first to tape out final designs on it.Well, GloFo does claim risk production H1/18 ramping to mass production H2/18
That being said just porting Vega over to 7nm seems incredibly costly, especially if they also plan to do NAVI on 7nm. Engineering cost per chip design has gone up a hell of a lot, and yes you have to do that between nodes even with a completed design. Vega seems a failure in terms of its original goals, there doesn't seem to be any hint of split wavefronts that papers originally posited would be there, and doesn't seem to be any better than Polaris in terms of performance/watt. I was wondering why the apparent lead engineer for Vega64 (and Vega in general?) had his resume up way before the chips actual release. I'd hazard the guess that AMD was none too pleased with the sim results but had put in way too many resources to change course, so away he goes.
Looping back around, if Navi shows up with some of the previously indicated features, a new memory controller, some vague new AI enhancements, and maybe that split wavefront packing that was supposed to be in Vega; then it'd make a lot more sens to spend time and money there, rather than rushing out a 7nm Vega. But hey, that's assuming it's on time at all. Maybe the timetables have changed drastically since last AMD talked about them, Vega itself has been delayed more than long enough.
Still... Just doubling the HBM stacks and the DP rate without changing anything else? That's a very odd design decision to say the least. I'd say the specs at least are extremely sketchy, as is the conveniently super wide TDP range.
