The FPS Review published a review on the Radeon RX 5500 XT 8GB vs. 4GB Gaming
A quote from the article:
When the AMD Radeon RX 5500 XT launched last December, one of the advantages that AMD specified is its ability to have both 4GB and 8GB variants. You see, the competition’s GeForce GTX 1650 SUPER only has 4GB models available, there are no variants with anymore VRAM. AMD made it clear in its launch that 8GB of VRAM could have advantages in gameplay performance, and thus would be one reason to buy the Radeon RX 5500 XT over a GeForce GTX 1650 SUPER.Radeon RX 5500 XT 8GB vs. 4GB Gaming Review
