AMD 7nm GPU News and Rumours 2018/2019

480 to 590 should be something like a 20-25% improvement. A Vega 56 is at least 50% faster than the 480.

Navi... we are all in the dark, in terms of roadmap it makes sense for Navi to be a Polaris replacement - and as a 7nm shrink and with architectural improvements you can probably expect a 30-50% increase in performance over the RX590. Possibly mid next year. I would guess we are going to get Vega64 performance at a much lower price point, but that is pure conjecture.

If you have the cash I would seriously consider the Vega56 it is a genuine and serious upgrade to your 480.
 
Probably a dumb question... But based on the pictures of the Vega 7nm chip it seems it is going to have a whole lot more transistors than a Vega64. Since GCN is limited to 4096 SPs and Vega already has that, what is the rest of that silicon real estate going to be doing?
 
I thought that GCN was never actually limited to 4096 CUs, it was hampered by a limit of 4 Shader Engines and keeping everything utilised properly? And adding more SEs would require a chunky amount of work? But haven't AMD actually resolved that 4 SE block with Vega, but just didn't implement more because the die was already huge?

Assuming I'm not talking utter rubbish, it's possible that Vega 20 has actually moved past the 4096 "limit" because AMD were able to build in more SEs.

Absolute spot on with what you're saying.
Myself was saying this before anyone looked into the architecture of Vega properly, I also identified the problems with Fiji and that the front end of Fiji was broken.

The disappointing part of Vega is that it's just a tweaked fiji with over 50% wasted hardware resources towards a half assed compute card.
They should have spun up two lines,
A real instinct like they are on 7mm, and Vega gaming without the hbbc and around 380mm2 die size.

Vega20 is going to support FP64 better than Vega10 and also include some new instruction sets (or how you want to call them). Lisa also said Zen designers did such a good job to increase hz that they are going to help gpu designers. Its all going to need more transistors.

New mask is going to cost tens or hundrends of millions of dollars, also sadly market has shown AMD they rather buy inferior or more expensive products from Nvidia. AMD also is going to make more money from Compute, AI or DL than they ever would from gaming. There is reason why even Nvidia is having additional cores on their GPU and its not to run couple of rays 30fps 1080p.

RX590 would be interesting card for me needing 1440p card, hope it comes soon. I would not mind if it had GDDR5x or GDDR6 but sadly it would seem it has GDDR5.

And pray tell how do you propose they "upset the apple cart"? You've seen their roadmaps, you've seen how long they've been in trouble, you've seen how long it's taken for Zen to properly take hold. Suddenly AMD are capable of causing immediate mayhem in the GPU space?

Freesync monitor and an AMD gpu, at the prices you can get them for, IS able to cause mayhem. My 56 and my freesync monitor is as smooth as my friends 1080Ti and gsync monitor. He can't tell the difference and he's played on both systems. Me either, yet my GPU and screen was around £240 quid less than his GPU and screen.

But the Average Joe consumer is an idiot and cannot be educated on how an AMD card that's been around for a few years when paired with the correct monitor will do everything you actually want to do for a fraction of the cost of the mighty Nvidia.

I believe the post I responded to was more implying "oh God AMD, why can't you just produce a 2080 Ti beater tomorrow instead of just rehashing old kit again" in order to shake things up. That ain't gonna happen any time soon.
 
So the rx590 is basically an over locked rx580 which is to be expected as there's no way AMD is going to spend fortunes on a new chip design at this point with 7nm around the corner. Hopefully it will give the 2060 a run for it's money.
