If the rumours regarding 4SKUs Big Navi 80CU etc are true then probably it will be the following SKUs:
1)TOP limited edition model: full die 80CU 16GB part overclocked around 3-5% (like 5700XT anniversary edition was before it)
2)Standard full die 80CU model 16GB
3)72CU part 16GB clocked lower than no2 model (at whatever frequency brings a 10% performance difference between no2 & no3) (don't forget Vega64 had +5% higher clocks and 14.3% more shaders vs Vega56, +20% in total more theoretical shading/texel power but in reality the 4K difference was only 10%, check also 5700XT vs 5700 etc)
4) 64CU part, cut down die with 192bit bus and 12GB memory, there is no way to be 16GB since the performance differentiation with the already lower clocked 72CU part will be very difficult and it makes sense for AMD to have a 12GB part since it has no competition from Nvidia regarding memory (10GB 3080, 8GB 3070) and AMD will shave off the cost of 4GB being more prepared to compete in a lower tier price point.
OK with these assumptions in mind and looking at the performance of the part that AMD previewed at Zen3 event we will have the following:
According to TechPowerup 3080 would be +9.1% faster at 4K from the model that they previewed. With my calculations this model would be only -7% in relation with 3080, I will use mine.
AMD by not saying which model it was, they somehow implied that this was not their top of the line part because otherwise it will be plainly obvious that AMD used their top product knowingly that it can't compete with 3080 and withholding the info from the consumers they plainly just want to blindside the consumers...
If the part that they previewed was no2 we would probably have:
$699 3080 10GB perf=100
$699 no1 80CU Big Navi 16GB perf=96 (+$50 vs no2, just a limited edition OC part)
$649 no2 80CU Big Navi 16GB perf=93 (-7% vs 3080, same performance/$ but 16GB)
$579 no3 72CU Big Navi 16GB perf=84 (10% performance difference in relation with no2)
$499 no4 64CU Big Navi 12GB perf=74 (around 2080Ti performance level)
If the part that they previewed was no3 we would probably have:
$799 no1 80CU Big Navi 16GB perf=106 (+$50 vs no2, just a limited edition OC part)
$749 no2 80CU Big Navi 16GB perf=103 (little chance AMD to be faster than 3080 and to have +6GB memory and the price to be $699 same as 3080, it's not Navi1 with no raytracing etc)
$699 3080 10GB perf=100
$649 no3 72CU Big Navi 16GB perf=93 (-7% vs 3080, same performance/$ but 16GB)
$549 no4 64CU Big Navi 12GB perf=82 (around +10% vs 2080Ti)
If the part that they previewed was no4 (no chance in Hell!) we would probably have:
$999 no1 80CU Big Navi 16GB perf=119.5 (+6% vs 3090, just a limited edition OC part)
$899 no2 80CU Big Navi 16GB perf=116 (+3% vs 3090, +10% vs 72CU no3 Big Navi)
$749 no3 72CU Big Navi 16GB perf=105.5 (5.5% faster than 3080 nearly same performance/$ but 16GB)
$649 no4 64CU Big Navi 12GB perf=93 (-7% vs 3080, same performance/$ but 12GB)
I wonder which scenario is better for the consumer.
At last the end, I didn't want to do it but we had a slow week regarding leaks, predictions etc from the usual twitter, Youtube suspects😉
