Which GPU to choose ?
I'm unsure what you're attempting to demonstrate here. Those who focus on a PCIe 4.0 setup have no real options but to opt for a different card with greater VRAM or switch to an X16 bus, or upgrade their PC to PCIe 5.0 just to potentially improve performance by about 15-20% when using an 8GB VRAM card. This upgrade isn't practical if you're already constrained by budget for a GPU upgrade.
What you presented highlights that the difference between 8GB and 16GB RAM becomes significant when the GPU lacks sufficient VRAM. The 16GB card clearly outperforms the 8GB one, especially at higher settings or in games that utilize more memory. You'll observe better performance with the 16GB card on PCIe 3.0 compared to the 8GB card even in PCIe 5.0, except in a single game, since the 16GB cards don't rely on system RAM to compensate for VRAM shortages.
Resolution doesn't affect the situation if you're already limited by VRAM at 1080p or you adjust settings to utilize available VRAM. The problems remain consistent across resolutions when VRAM is constrained.
Hello,
The RX 9060XT is not available within my budget in France (380eur). I could purchase a RX 6800 for 265eur. Is this card a better and more durable option compared to the Intel Arc B580?
The RX 6800 non XT is roughly comparable to the RX 9060 XT with 16GB, though you won’t get the same hardware support for FSR 4 as you do on the XT. AMD is developing FSR 4 for older GPUs, and it seems likely they’ll release it within the next year or so, although no official date has been announced yet.
You can still run FSR 4 on older graphics cards by manually modifying them, and the DLSS Swapper team mentioned they plan to add this feature if games support it. This would let you switch between DLSS, FSR, and XeSS versions for improved performance. There are also additional tools available to convert DLSS to FSR 3, which can be useful when using GPUs that don’t support DLSS, such as the GTX 10 series or RX 6000.
Regarding the B580, it wouldn’t be worth considering, as its performance is about 2 tiers lower (roughly 30-35% slower) and even with upscaling it won’t match the RX 6800’s capabilities.
