Quick Answer
For Genshin Impact at 4K, both the RTX 5070 Ti and RX 9070 XT clear the practical frame target with room to spare, so the RX 9070 XT is the smarter pick at roughly R16,500 to R20,500. Put the saving toward better cooling rather than GPU you will never use.
RTX 5070 Ti and RX 9070 XT in Genshin Impact at 4K
Genshin Impact is open-world action gacha that is capped at 60 fps by design, so headroom goes to stability not bigger numbers. On a 4K 144Hz panel, the RTX 5070 Ti brings 16GB of fast GDDR7 plus DLSS 4 Multi Frame Generation, while the RX 9070 XT answers with aggressive raster performance and a 16GB buffer for the rand. At 4K plan to use quality-mode upscaling on either card, since native 4K is the most punishing target and even these higher-tier cards lean on it to hold frame rates well past your panel refresh cap. The card you pick matters less than the panel and CPU you pair it with here.
Building Around the RX 9070 XT in South Africa
Whichever card wins on the day, feed it properly. Pair RX 9070 XT with at least a current six or eight-core CPU, 32GB of DDR5 for Genshin Impact plus background apps, and a fast 1TB NVMe SSD for the install. A 750W 80 Plus Gold power supply gives headroom for the 300W to 304W draw of these cards. Airflow matters in a warm flat where ambient temperatures climb past 28C, so a mesh-front case with three intake fans keeps clocks stable through long sessions. A 165Hz panel paired to this card usually feels like a bigger jump than chasing peak averages.
Impact at 4K, set a target frame rate first, then pick the cheaper of the two cards that holds it on the panel you own. Enable quality-mode upscaling before adding more GPU budget.
FAQ
Is the RTX 5070 Ti or RX 9070 XT better for Genshin Impact at 4K?
In short, both cards clear the target comfortably, so the RX 9070 XT wins on rand-per-frame value since you are not spending money you will never use. On the panel you actually own, the cheaper card that holds your target frame rate is the right answer.
How much should I budget for these cards in South Africa?
Plan for roughly R19,500 to R23,500 for the RTX 5070 Ti and roughly R16,500 to R20,500 for the RX 9070 XT at current Evetech pricing. Add the cost of a suitable PSU and case if you are building fresh rather than upgrading.
Will 16GB of VRAM be enough at 4K?
For Genshin Impact, the 16GB GDDR6 on the RX 9070 XT gives extra comfort at higher textures, while the 16GB GDDR7 on the RTX 5070 Ti pairs with smarter memory handling. At 4K both stay sensible for this title.
