They probably DO have the performance numbers - but it is crazy to release anything right now due to the 3080/3090 frenzy. Let that settle down a little then release the info when the embers settle.

When did any performance numbers appear for the 3080 before Jensen's 1st Sep announcement?

Agree. I wouldnt be completely gutted other than the self-hype we all built, if it was a 3070 beater but thats it then it can cost the same as a 3070 or do one.
I'm probably tired and misread something... thought you were talking about AMD releasing performance numbers....

I mean, if we take the timeframe of the nvidia release (17th to the announcement on 1st, you can use the leaked performance numbers x days before the 1st) we can work backwards of when useful information is hopefully shared.
No real urgency for them to do so though as they had no competition at that point in time. Even the date of the AMD keynote wasn't announced until a week after the 3080 unveil (Sept 9th I think?). Whereas AMD will be launching with the competition already out there (albeit with a stumbling start supply-wise).
But it wouldn't really be any different from this generation. - 30% or so. I'm hoping they get closer to Nvidia's fastest card this time and a 3080 competitor would be doing just that.
Very intresting thanks for posting. Bit at the end about AMD reps showing off a card that competes with the uncut down Ampere proffesional cards at a lower TDP. If that is true then there is hope of a competetive higher end gaming card this time around.

I dont think you could keep mentioning 'BIG' navi if they thought it was not gonna be something to challenge to be honest.
If you cast back to the MLID last part - he mentions they could have used regular DDR6 and got more bandwidth at a lower power consumption. Then relate that to the AMD lineup which he said was I think 250w.

I'm getting a bit tired of him saying he has more Navi info that he hasn't revealed yet, he's been saying that for weeks.
If and when Big Navi is released, and assuming it can compete with 3080 (which I really think it will!)... it'll be the greatest uplift in a gen EVER I think... as where the 5700XT sits right now today, to have made that kind of ground up in ONE gen will be an incredible achievement from AMD... hoping they do I really do... basically it'll be a 100% performance increase to be hitting 3080 speeds... and that's a lot

Im hoping so for all the vega owners too as it means holding off on the 5700XT which wasnt really a decent leap up so agree it would be a huge step. Not sure if the Ryzen guys were drafted in to help but it sounds like they needed all hands on deck otherwise they would be way behind nvidia.
Not PCB that’s fair game to an extent but I heard that they are restricted in terms of the cooler, they can only do certain designs which may well be true given they are always triple fan etc etc nothing new... Presume they get forced to do something which makes the card different from NVs.
supposedly some of the engineers specialising in power efficiency on zen processors worked on RDNA2

more in the link.
5700xt\radeon vii were more or less sidegrades from a vega 64 at best. 64 is still a decent card though depending on what you play, though starting to show their age in some games.
I kind of like the Radeon VII, despite the ridiculous cost. It was a marked improvement over Vega 64 and the die shrink to 7nm resulted in a much smaller die size than Vega 64, and higher clocks too at a similar TDP.
EDIT - Apparently, there are 4 TMUs per CU, so a 80 CU GPU should have 320 TMUs (double the 5700 XT).
This means perhaps the most important thing we don't know is how many ROPs an 80 CU RDNA 2 GPU would have. Ideally, this would be about double the amount the 5700 XT has, which would be 128 ROPS.
The other factor affecting performance is memory bandwidth, I'm not worried about this really, I doubt using GDDR6 would hold back performance much, and they can use a larger memory bus width if needed.
