No it doesnt. A 50% performance per watt improvement will increase the performance up to 4090 levels @4k @350watts.
Where are you getting 64% from?
100%/300w*1.5*350w = 175% of the 6900xt speed at 4k. According to techpowerups 4k charts 4090 is 75% faster than 6900xt
I wondered about that. Total board power would theoretically mean the max power the board would chug under the most strenuous load, so while 100% GPU load and USBc output?
Have you seen confirmation of this somewhere?
Nvidias 20 series had USBC right? So were their tbp numbers inclusive of...
If it seems unrealistic to get a 56cu die from a 64cu die due to yields, than a 64cu die from a 80cu die should be extremely unlikely. Where does that leave the 6800?
Something like this seems to make sense to me more so than the rumoured 72cu 6800xt
6700xt 40cu
6800xt 64cu
6900xt 80cu
This lends even more credence to the possibility of the 6800xt being a 64cu card.
If we take the techpowerup review of 3080 trio, 80% faster than the 5700xt at1440p
3080=100, 5700xt=55.
55 x 10% IPC increase, x 80% more cus, x 21% higher clocks = 131. Theoretically 30% faster than a 3080 at...
Well, not if you're a NVIDIA fan
But anyway, the die sizes definitely didn't add up to the rumoured cu counts. But that was assumed to be due to the infinity cache. Still, this seems to be next level sandbagging AMD has engaged in
But see this is the part that currently seems unreconcilable with 6800xt being navi21xt, 72cu part.
With TSMCs reported defect density in its 7nm process of 0.09, the ratio of good dies to defective dies is around 2:1...
While he said that i don't think it's likely. That leak would have to come from AMD direct and considering how tight lipped they've been i doubt they will leak numbers 4 days away from reveal. The numbers are too well rounded too, could just be estimates
Says info was provided by aibs who were given by amd. Could be true, but also might not be.
Still doesn't make sense as to why the 6800xt is a cut down die, why AIB partners would only get a cut down die when most dies produced would be full 80cu dies, why there is no 6900 non xt and why there...
So theres something Im having doubts about and that is that the XTX die, AMD exclusive, is either the only full die (80CUS) or a higher binned full die.
If its a higher binned die, the performance delta over the remaining full dies wont be that large I imagine. The 5700xt lisa su edition was...
Perhaps in some stages? I'm not savvy on the process except that they will definitely use different machines at some point.
So if rdna2 was intended to be fabbed on euv, then they would not be able to decide to reduce volume to free up capacity for zen3 i believe
