XFX Radeon RX 7800 XT SPEEDSTER MERC319 16GB GDDR6
The RDNA 3 architecture and 16GB of GDDR6 memory on a 256-bit bus deliver high frame rates at 1440p, with a 2565MHz boost clock pushing 37.3 FP32 TFLOPS. Its triple-fan MERC319 cooler keeps the 236W TDP in check while the card maintains a relatively compact 2.75-slot design for broad case compatibility. This GPU is best for 1440p gamers seeking strong rasterization performance and 16GB of VRAM for high-resolution textures without stepping up to a flagship price.
