NVIDIA 3090 or AMD 7900XTX for 4k build ?

Hello,

I'm building a new FS pc. Need help finalising the GPU for the build. I'm in India, so prices are in INR.

I can either get an Asus Strix 3090 for 70k or a Sapphire Nitro 7900XTX for around 105k. Is there any advantage to getting one over the over ? Both are within budget tbh, I'm just curious if NVIDIA last gen DLSS has any significant advantages over current gen AMD.

Cheers

comparison,  better performance with 7900XTX

The 7900xtx does get better raw performance in most cases, and they're almost toe to toe in 4k. I'm wondering how much will DLSS help in that regards as 4k/60fps is still not guaranteed at max setting.

I wouldn't trust those comparisons that average results over many titles and don't even include MSFS. Every title performs differently, some favour Nvidia cards, others favour AMD cards, and some profit more from generational improvements than others. What's more, MSFS keeps changing due to the steady stream of sim updates, so benchmark results from a year ago may no longer be applicable to the current version and can be a lot more demanding with a lot of add-ons installed.

The only systematic and comprehensive review of current hardware for MSFS (DX12, three typical resolutions, various flight scenarios) is this one: https://www.pcgameshardware.de/Microsoft-Flight-Simulator-Spiel-15259/Specials/Benchmark-2023-CPU-GPU-1411823/

It's in German though, but you can use the Chrome browser's translate feature or copy/paste the link into the Google Translate text field. The translation isn't perfect, but you get a pretty good idea of the test methodology used and the results. 

The 7000 series AMD cards seem to hold up pretty well, and even the 7900XT beats the 4080 in MSFS at all resolutions, and the margin gets larger at resolutions below 4K. VRAM can become an issue in some locations on Earth, 12GB may not always be enough even without using add-ons.
