Question 7900 xtx nitro+ VS 4080 Asus Tuf OC

[naguib nader]

Hello Everyone
my old 2080 just died so i want to get a new one soon kind of confused about the above edition less than 200$ difference between two of them
i m just upgraded my rig to be

i5-13600KF
Z790 rog strix F gaming
32 Ram 5200 MHz
thermaltake 1650 watt
Corsair Obsidian 1000D
Alienware 2k 120 MHz (was planning to upgrade it to 4k 120 MHz) but the priority now is for the GPU

i planning to stick with the new card for a while so i want to be able to run 4k smoothly in the future
i don't know which to pick the AMD as the bigger vram is really tempting but without RT or DLSS 3.0
or stick as usual with nividia less vram but with RT and DLSS 3.0
also have no clue about heat and coil whine could not find any review for both edition
i don't have any concern about the size or power consumption as my PSU could handle even 2x4090

thnx in advance for any help would be much appreciated

Which card is priced $200 lower? Region and availability can and will drive prices up or down. I'd pick the RX over the RTX

You might also want to specify the games you want to tax the GPU with. Resolution wise, they will both get the job done.

7900 xtx is less than the 4080

as i mentioned in the thread my aim to play 4k @120 MHz or above as i will stick for this upgrade for a while so i want it to give best option regarding 4k gaming regardless what type of games

That's not entirely accurate. While it is true that the RX 7900 XTX doesn't support DLSS (in any form), it does support RT and does a pretty good job of it, matching the RTX 3090 Ti:

Sure, the RTX 4080 is definitely better but your impression that the RX 7900 XTX can't do RT is the same as saying that the RTX 3090 Ti can't do RT. Sounds pretty ridiculous when put that way, eh?

In non-RT applications (which is the vast majority of games), we have the RX 7900 XTX ever so slightly ahead, but not enough to matter. I consider less than 5% difference to be a tie:

As you say though, what cannot be overstated is the 8GB VRAM advantage that the RX 7900 XTX has over the RTX 4080.

This is how I look at it... A card's VRAM capacity should be relative to the power of its GPU. The higher the GPU's performance, the more VRAM the card needs. This is because ideally, you want the amount of VRAM and the power of the GPU to become obsolete at the same time. Of course, that's really hard to predict to the point that it's almost impossible because new technologies like RT and extremely hi-res texture packs tend to be kept secret until released.

Since VRAM isn't an expensive commodity (Intel charges only $20 more for the 16GB A770 over the 8GB A770), it's always better to err on the side of caution with the amount of VRAM on a card. If the card becomes obsolete because the GPU is no longer strong enough, I call that a natural death because the card was never hampered by anything. On the other hand, if the card becomes obsolete because there's not enough VRAM but the GPU is still powerful enough to keep going, that's a premature death.

The way I see it, 16GB is the correct amount to prevent an RX 6900 XT from becoming crippled, but the RTX 4080 is on another level. Even the RX 7900 XT, a card that is nowhere near as fast as the RTX 4080, has 20GB. I believe that the 16GB of the RTX 4080 will become a limiting factor in the future, especially at 4K. Admittedly, I don't know how long it will take but I am certain that it will happen and limit the life of the card itself.

A good metaphor is like when you're building a gaming PC, you want the GPU and CPU to be as close as possible with regard to frame generation. A super-powerful GPU with a weak CPU is a waste of money and vice-versa. With video cards, you want the amount of VRAM to last at least as long as the GPU because the GPU gives you the performance over time and the VRAM allows that performance to continue over time. Having not enough VRAM to match the power of the GPU creates a temporal bottleneck. The GPU gives you enough performance to last X-number of years but the VRAM gets in the way prematurely if there's not enough.

or stick as usual with nividia less vram but with RT and DLSS 3.0
also have no clue about heat and coil whine could not find any review for both edition

Coil whine occurs with all cards and it depends on the individual card itself, not the brand or model so I wouldn't worry about that.

Personally, for $200 less, I'd take the RX 7900 XTX any day.
