The Radeon RX 6750 XT will include 12 GB of GDDR6 memory, which implies it will be coupled to a 192-bit wide memory bus, which remains to be a constraint. AMD attempts to compensate by operating it at 18 Gbps (effective data rate) and adding an extra L3 cache on-die on the GPU. Both will assist you at Full HD and WQHD resolutions, but performance will suffer if the L3 cache is drained, mostly in GPU-bound Ultra HD.
The new card, like the original Radeon RX 6700 XT, has a strengthened metal frame, a beautiful backplate, and ASRock's Phantom Gaming 3X Cooling System. It also has a huge heatsink, heatpipes, v-shaped air vents, and three axial fans, one of which features an aRGB fan in the centre of the card and supports ASRock's Polychrome Sync.
Power is supplied via an 8+8-pin layout neatly recessed into the backplate, and considering the enormous magnitude of the cooler, a factory overclock is included as standard. Don't expect to make a lot of money. Sapphire officially lists a boost frequency of 2,623MHz (2,554MHz game clock). Frequencies oscillate at ~2,550MHz in real-world use, while the large 12GB GDDR6 frame buffer, connected via a 192-bit bus, operates at 18Gbps.
The card is quite huge and takes up 2.5 PCI-E slots. So make sure you have enough space in your chassis. It includes an ASRock Phantom Gaming 3X Cooling System with three striped axial fans to cool the big heatsink with heat pipes. There's also a strengthened metal frame and backplate, which adds stability and aids in cooling.
