AMD 7nm GPU News and Rumours 2018/2019

Its rumoured to be PS5 centric true and be around GTX 1080 performance at mid rage prices
So pretty much vega 64 mark 2 in performance respects. Les power draw is a given if its going to be in a console.

We already have downclocked/gutted/hybrid Polaris/Vega designs in consoles. I still think they need to redesign there memory controllers and GCN.
Define mid range in today's market?
Isn't navi meant to be the last gcn iteration, or is it the start of the newer designs? Can't remember which navi is meant to be.

Still GCN.
He's talking about mid rage. So somewhere between the sad acceptance of £200+ for a 580 and the frothing anger at 2080Ti prices.
Hmm, i thought navi was the start of a new architecture. Think gcn has been flogged to within an inch of its life by this point. The successor is due in 2020/21, so virtually 10 years amd has been on gcn by that point.
I'm pretty much expecting Navi 10 (what's coming out next year) to be Vega 56 & Vega 64 for £100 less, maybe 10% better performance, and probably a bit less power draw. I'll be very much surprised if it's any better than that at this point. Maybe in 2020-21 there'll be some real top end cards to go toe to toe with Nvidia's 2080ti/3080ti(?) but who knows.
Seriously thinking of just buying a used 1080ti and ride out the next 3 years but I'm not so confident in it doing 4K60fps in CP2077 when it comes out.

It's good and bad, at least it's well known by devs now for optimising for
I mean look at the 580, it isn't doing too badly!

Navi is the last GCN. Arcturus is all new in 2020.
I really want to see Navi 10 with GDDR6, surely it'll be a wedge cheaper by not messing with HBM?

Interesting, is the 570 the most overstocked card right now? Any chance of 580 or 1060 prices tumbling too?
I think hbm for the most part was a bust, it has its applications but it still seems to make production more tricky which slows down availability. It does save amd a bit of power but adds significantly to the cost. It did enable smaller cards to be built but that seemed to be more of a niche thing that amd never really followed up on after fury x and nano.
HBM has its place but AMD pursued it too soon and in the wrong way - but then it might have been the only realistic way they could develop it for the right markets I dunno. All I know is GDDR was a better choice for gaming cards over this period and will do well enough until we really need those next generation memory technologies.
EDIT: Still remember the for want of a better way to put it frosty reception my posts got when I said that 3-4 years ago but here we are.

They had to use HBM, to keep within any semble of power budget. A 384/512bit memory controller + the dram packages would took a massive chunk of the power budget which otherwise would have been spent on CU's etc.
That's really down to the inefficiency of the core though, they desperately wanted to get the first hbm gpu on to the market but seemed to do it more so for bragging rights than much else. Availability was pathetic, issues with the pump, hand tuned drivers for the 4gb limit never really seemed to materialise. Had they had HBCC in place for its launch it may well have been a better card.

Gents don't forget that AMD shares 1 GPU between consumer cards (Vega 56/64) and professional cards (Pro, Instinct etc). The latter are very low powered setup, while the mainstream consumer +60% overclocked to start with.
It doesn't have the ability (cash) to produce a big chip and start chopping it. Also is the reason why Vega 64 (and the FE) perform so close to the V100 based card when comes to computing (AI etc).
A mere £450 card, performs within 80% of a £8000, before downvolting and overclocking. And the FE performs 90% of the V100 before downvolting and overclocking also.
Kinda funny when you are using matrix computing benchmarks to measure this, being so close to a card that has dedicated parts (tensor cores) for such computations.
You will find also many discussions were whole businesses grabbing Vega 64s since last year, for AI and other professional number crunching purposes, (not mining). Since it costs 1/20th the price of the Nvidia top AI card, for barely 20% less perf!!!

No but it does really well in scientific compute, cryptography and a number of other compute areas beating everything NV had to offer at the time including Titan V and all but Nvidias very best when it comes to compute.
I have posted this before but will put it here again: https://techgage.com/article/a-look-at-amds-radeon-rx-vega-64-workstation-compute-performance/
As a workstation and compute card it is actually pretty compelling.
