All die sizes are within 5mm^2. The poster here has been right on some things in the past afaik, and to his credit was the first to saying 505mm^2 for Navi21, which other people have backed up. Even still though, take the following with a pich of salt.

Navi21 - 505mm^2

Navi22 - 340mm^2

Navi23 - 240mm^2

I mentioned a certain source told me that clocks in the lab were close to 3ghz. Pro variants are usually slower (these are all pro cards) so it would not surprise me if the final card hit 2.75-2.8 ghz.

Forgot the hype, we are entering the realm of science fiction!
One 2.5GHz card (as always, overclocked and overvolted) I can accept, but working on this clock comfortably and with an ever higher tier of cards coming? This thing would crush Ampere (would the memory get in the way?), how can a sudden upset to the market like this be possible?

I can't believe this, this must be another delusion off the level of Adored Zen 2 lineup, right?
People, I come here exactly to kill fantastical rumors and hype like this. o_O

AMD with RDNA2 exceeds ALL of expectations...
But those are all just rumors! *rearranges sandbags*

Kidding aside, by all indications the next gen consoles managed quite some timing: first Zen 2 being as competitive unrivaled, and now RDNA2 is looking pretty swell as well. Even 3 years ago that was not natural to foresee.

...giving up the consoles to AMD was a major mistake for Jensen (...) Where would AMD be without all these collaborations from 360 era till now...
Without the semi custom business AMD would very likely be bankrupt now. So thanks Nvidia for leaving consoles to AMD!

Btw. the collaborations in the console space technically started with ArtX (itself a breakaway group that worked on Nintendo 64 at Silicon Graphics) which ATi bought back in 2000. David Wang is from that lineage.

Well, i remember in the past various people claimed that AMD SMT version will not be beeter vs Intel SMT.

Hm, up to 250W for 80CU at 2.2ghz is kind of nuts but that is exactly likely what we can expect.


If you look at 15W/Renoir APU Ryzen 7 4800U performanse+power efficiency, and this is "old tech or Zen2+Vega 8CU at 1800mhz".

Can you imagine, what can you expect from Zen 3 APU with power efficiency improvments=performance of Mobile 8-12 CU RDNA2 GPU.I can imagine, and it will be kind of ............................:screamcat:

I really hope this is true as it would finally bring unrivalled competition to the GPU space.


If all of this is true it's almost like R300 vol 2 moment. I can feel the hype coming over me 😀

I would't dare to visit r/amd now. I' m sure that by monday a vocal minority will be pushing 3Ghz theories as fact.

Mac Pro has Navi 10 GPUs. So its easy to see next iteration of MP to use Navi 21 GPUs.
Right. I'm not 100% sure on that being a Mac Pro only thing, though. Doesn't make sense to run older Vega parts in the other Macs and only upgrade the Mac Pro. If it's that then it'll be a while until Apple come out with their own dGPU.

Lol. Hype train has reached moon orbit.

3GHz? Maybe under LN2.
It got an eye roll from me. Reminds me of the weird stuff I see coming out of a demented orangutans raging entrails destiny prior to Zen 2's launch or any dumb piddle paddle they've put out.

If that doesn't makes sense to you or anyone else, look at the first letter of each word after "I see coming out of" including the lone 'a.'

No point in giving SEO brownies to a rag. I thought about using italics on the individual letters but it's more fun this way to see who can figure it out. Need to figure out cleverer terms for the other rabble.

I know it looks crazy, but i still remeber that my GTX970 G1 boosted at 1300mhz and then i get GTX1070 gainward GS and it boosted at 2000Mhz.Thats 53% clock increase.My sapphire 5700xt nitro+ boosted at 1950-2000mhz stock.If that 40CU SKU will boost at 2800Mhz it will be only 43% clock increase.So nothing we didint see already in the past.Looks like AMD have "pascal" moment with RDNA2.
Nvidia must know it because they releasing 400w+ monsters just keep with it LOL.

Well yes, but Nvidia has had the better architecture for quite some time now. All it takes is a better engineering process and it’s probably back to status quo. AMD has generally had a good chip, but seem to always add too much voltage. They also preferred HD libraries vs high performance ones. This is why AMD’s chips are much smaller in size compared to Nvidias.
All it takes is for some genius at AMD to say let’s build a big chip this time, screw density, and let’s have day at it.
So either stupidity is now gone, or Nvidia foooked up badly hoping Samsung cheapness will keep their stock holders happy

While I would absolutely love if it actually did reach 3GHz just to laugh at how AMD created a GPU that actually competes with ARM in clocks... Yeah, REALLY doubt that one I'm afraid.
