Isn't it possible that AMD will save it's most powerful GPU designs for 5nm TSMC fab process?

Tends to suggest 5nm is coming late 2021 - I'd assume that will include GPUs fairly shortly after Zen given the way they are approaching the product stack.

Wonder if Intel will still be on 14nm then

It could literally be (almost) any time in 2021, that's the beauty of it, endless speculation. There's a slight chance it could be delayed, in which case, the vagueness has them covered.

I think people are kidding themselves if they think this wasn't big Navi being shown off (as some still believe) - I'll concede it is possible it isn't the biggest of big Navi (though I have a lot of reasons to doubt that) - but they'd have to have pulled off a miracle to get this kind of performance out of the kind of silicon that would be commercially viable as a Navi 22 type part - the physics just don't work.

For instance a lot of their 50% perf/watt improvements will come from things like more optimised input to setup engines allowing lower power draw at the same performance, the ability to better gate power usage on unused parts of the GPU during processing, etc. which might allow for a small reduction in area and a small improvement in frequency but it is going to be single digit percentage type stuff versus the 10s of percent for reduced wattage.

Most importantly, Herkelman stressed that AMD didn’t state which Radeon RX 6000 graphics card ran these benchmarks. We don’t know whether these results come from the biggest Big Navi GPU, or a more modest offering. (Herkelman also said there’s still fine-tuning left to do before launch.) AMD’s Ryzen 9 5900X, the CPU used for the tease, also hasn’t been tested by independent reviewers.

And based on MLID video he believe they may have another Lisa Su Edition that is higher then what's shown. However, the general consensus is that AMD has something left to show by the time they are ready to release. With availability starting several weeks after launch.

Me personally? I really don't know either way. I just know that it's not a RX 6000 Series Card. However, I will take Herkelman's word into consideration until it's proven he's lying through deception.

The latest rumor is that AMD is finalizing specs now. And per MLID they are going "all out" this time. We will see.

Well the name of the GPU AMD said they would release later on this year, around January 2020 (rumours for names were flying around ever since the launch of RX 5000 series) was 'Big Navi'.

The Radeon RX Twitter page confirms here that 'Big Navi' was the GPU they were previewing on the 8th October.

There's probably some good reasons why AMD didn't confirm the GPU's name on the slides themselves, isn't it far more likely that GPUs more powerful than 'Big Navi' will come next year?

I'd go with the Newegg spec estimate of 300w tdp for the Big Navi GPU shown in the benchmarks. They can bring down the TDP of future graphics cards next year by switching to 5nm.

My current GPU has a TDP of 275w (R9 390), so hopefully I'd still be able to upgrade to Big Navi with my Seasonic PRIME Ultra Gold 650W PSU (if the price is reasonable).
