just my re-search ,calculation and sharp compare and etc etc.. info
well,i cant see that rx 6900 xt can reach even close rtx 3080 performance..i say rtx 3080 10/20gb is 20-25% faster.
amd use it 'teaser' video 5900xt 12-core cpu ,what ,if rtx 3080 get it for test,helps much just rtx 3080/3090 gpus, bcoz one of limited/bottleneckthouse gpus are cpu ,and 5900 xt 12-core helps.
also rx 6900xt have 16gb memory ,and its helps just there high resolution gaming, like amd 'teaser' video' test ,4K resolution.
still different is quite clear, even amd own cherry picked games...what is odd choice from them, bcoz almost no1 test site NOT use thouse...hmm.
lol unpossible to compare. that amd want..or why?
come on amd.?.lol
summarum
rtx 3080 20Gb gpu with amd 5900xt gpu or intel Rocket Lake 11th generation cpu,( coming btw Q1/2021, helps, i dare say, 5-10% more.
so different is between rx 6900xt vs rtx 3080 10GB/20GB is between 20-25%
meaning practical example rx 6900 50fps VS rtx 3080 60 fps..
i feel i do favor for amd big navi that omen..lol
we,let see.
finaly, i cant belive amd 300W tdp for rx 6900 xt.. hmm well sure amd can say tdp is 300W ,but its unpossible for example gaming session....
bcoz even single rx 5700 xt, its fastest variant, sapphire nitro+ SE AIB gpu, official tdp is 285w and measured 'average gaming' (yes, Techpowerup test) also, 285W
btw, peak was 296W ...wow.
hm,its btw,more than example rtx 2080 ti AIB versions,example MSI rtx 2080 ti Lightning eat watts, its have average gaming tdp 279W....6w less than rx 5700 sapphire nitro+ SE AIB gpu...
but,btw again, rtx 2080 ti Lightning is 44% faster than rx 5700 sapphire nitro+ SE AIB gpu,this for 4K gaming...hmm
(Techpowerup test) tx again...
so, i dont think that rx 6900 xt what practical is 2x5700xt for CF mode can do jod same values.....lol no way.
we must remembe,there is no different rdna2 and rdna1 for moust important issues
and i mean both use still 7nm core and both use still also gddr6 memory.
also RT support eat juice, 25w?
i say ..hmm. i dare say.. 360W average gaming, for rx 6900 xt, peak near 400w, this IF rx 6900xt get even close ,that 20% of rtx 3080 speed.
this bcoz there is several test for internet with rx 5000 gpus CF modes.
and example when testing CF mode rx 5600xt and rx5700, they measure tdp 464W, yes 464W....
gogole and you find.
if rx 6900 xt loose about 35% i belive 300w tdp.
so much power must have these days top gpus that it need current alot.
so,we must remembe that rx 5700 xt is already 7nm gpu, so amd cant do much there power saving,
but rtx 3080 is 8nm gpu and its little brothers rtx 2000 series is 12nm maded,different is big ,50% smaller die,its alot!
so when we know that rtx 3080 have amazing performance it tdp and average gaming measure watts eat, 303W, is excellent.
well ,we seen soon.
rtx 3000 series really earn all its glory.yes
also, when rtx 3070 and rtx 3060 ti coming (heard that 3070 Ti is cancelled..?)
i bet thouse gpus oc'd very well,and my calcuting at least rtx 3070 AIB Lighning is hard case rx 6900 xt...maybe, but sure is,its alot cheaper. 200$ i guess
well ,let see that too soon.
p.s. rtx 3090 is it own category, but its make just 8K gaming,rtx 3080 10gb & 20GB for 4K gaming ,rtx 3060 ti and rtx 3070/super FHD and WHD gaming, rtx 3070 Super (16gb) also 4K gaming.
3rd gpu:
but, where is intel Xe gpu!?
it is great to see 3 gpus battle line!
rs 6900 xt price:
i cant belive that amd cant sell rx 6900 xt under rtx 3080 price, little more, i say 699-799$
notice...
amd need cash,moore than nvidia.
its cant continue forever overdraft, bcoz its zero/2-3% profit price politics.
all great end of weekend!
