Frankly speaking I've never figured 3060Ti as a "gem" - maybe it's just retrospective thoughts inspired by GT4050 aka "RTX4060"? OFC that thing would never rival midtier GA104 with given AD107, even with help of miraculous TSMC 5nm.
I thought 3080 was more of a "gift", when nvidia tear flagship GA102 from its heart for a "mere" 700$.
3080 is nothing like a 3090 and Samsung 8nm (10nm in reality, just renamed and on par with TSMC 12nm) was very cheap and cut down due to poor yields at Samsung. 3000 series was priced low mostly due to using Samsung - Nvidia came crawling back to TSMC with 4000/5000 series and they perform massively better when looking at perf/watt, which is the most important metric for a GPU.
3090 = ~21% more CORES and bigger bus too, 384 bit.
3090 Ti had like 25% more cores.
10GB vs 24GB, massive difference however 10GB was/is plenty for most gamers still, especially when you don't max out new AAA games completely at 1440p/4K, which no-one probably does on a 6+ year old GPU but at least it has 100% support for DLSS 4, unlike AMD cards from that time.
Good upscaling (with broad support) beats VRAM in terms of longevity. Any day of the week. You can always get around lack of VRAM. You can't get around slow GPU performance and bad upscaling.
I will take 10-12GB VRAM with good upscaling any day over 16GB VRAM with crap upscaling, especially if the latter has mediocre RT perf and lack of features as well.
Cards like Radeon 6800/6900 series aged like milk even with 16GB. Arch was poor, RT slammed the cards and RT elements are forced in many games and have for years. No AI cores to bruteforce FSR 4, hence why Radeon 6000 first get FSR 4 support sometime in 2027, they are probably to slow to run it well, bruteforcing FSR 4 with INT8 and perf takes a huge hit, GPU will buckle.
3080 10GB vs Radeon 6800 XT 16GB - Which aged better? 3080 did. Upscaling really was gold, and Radeon 6000 still don't have FSR 4 but will "maybe" get it in 2027 sometime, no FP8 means INT8 bruteforcing so it will probably not work good. 3080 have Tensor cores which does the work. Nvidia futureproofed RTX, hence why DLSS 4 works on all RTX cards, native FP8 or not, yet RTX 4000/5000 does it better than 2000/3000 due to native FP8.
Lacking FP8 and AI/MATRIX CORES is AMDs big problem with FSR 4 on older cards. Can't fix what is not present. Nvidia had Tensor cores since first generation of RTX, 2000 series from 2018. Hence DLSS 4 support is no problem at all.
Why yap about old crap tho. People should be using RTX 5000/4000 or Radeon 9000/7000. Everything else is meh and dated. If I had to choose anything older, RTX 3000 is the only cards I would touch with a ten feet pole. RDNA 2 is dead in the water and everything before RDNA 2 is literally trash bin worthy.
If you asked some random dude to pick a 3080 or 6800XT, or 2070/2080 vs 5700XT, absolutely no-one would pick the AMD cards. That is how shitty they aged and with no FSR 4 support, dead in the water today.
AMD should literally just focus on Radeon 9000/7000 and the future. No need to waste ressources on getting FSR 4 to Radeon 6000 series, too slow and old to use it anyway.
People ramble about VRAM like the most important metric for longevity. It's not and it won't matter at all if GPU arch is pure crap with no support for good upscaling.
RTX 2000/3000 vs Radeon 5000/6000 is the proof. 8-10 years old now, Nvidia aged like wine compared to AMD, due to DLSS 4 support on day one and the fact that AMD GPUs back when buckled when just a tiny bit of RT elements were present. GPU was pure crap and only able to do simple rasterization. This was partly fixed with Radeon 7000 and completely fixed with 9000 series. Future looks bright for AMD GPUs, if they just forget about old crap archs and look forward instead of backward. No-one freaking cares about Radeon 5000/6000 that old trash is dumpster worthy tech.
Can't wait to see RDNA 5 / UDNA, if AMD takes this serious, they could shine, now that upscaling is fixed with FSR 4.x - I sadly think they won't try much and insist on staying in the "low to mid-end market" like Radeon 9000 is aimed at. Because they are CPU first and makes more money here. Making cheap gaming GPUs is not their goal. Eats away at their TSMC output for little margins.
AMDs priority list:
1. Enterprise CPUs
2. HEDT and desktop CPUs
3. Enterprise GPUs, AI etc.
4. APUs, and custom APUs (OEM PCs, Consoles etc)
5. Lunch break
6. Gaming GPUs
If in doubt, just read their financial reports.
