Sapphire Radeon RX 6750 XT Nitro+ review - Product Photos

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 if the L3 cache is drained, mostly in GPU-bound Ultra HD, performance will suffer. 

Sapphire includes their triple-fan Nitro+ system, nearly identical to the cooler used by the Radeon RX 6800. The board dimensions are identical at 310mm x 131mm x 51mm, and the design, as previously, adopts a familiar black and silver color scheme while maintaining the customary four of display outputs; a single HDMI 2.1 and three DisplayPort 1.4.

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. 

Do you prefer to keep your GPU operating within its capabilities? Sapphire's alternative BIOS, which can be accessed through the hardware toggle or the Trixx companion app, reduces the boost clock to 2,600MHz and game clock to 2,495MHz, but with the performance mode being very silent, why even bother?
