AMD’s Radeon RX 7800 XT

AMD’s Radeon RX 7800 XT has been within the information currently. The price range RDNA 3 GPU is predicted to hit the market within the coming months with a price ticket of $549-$600. It can allegedly function 16GB of GDDR6 reminiscence by way of a 256-bit bus throughout 64MB of L3 Cache. The Navi 32 GPU powering it (or a cutdown Navi 31) will function 64 to 70 CUs, netting as much as 4,480 stream processors and a bandwidth of over 600GB/s.

Beforehand, Navi 32 appeared like essentially the most logical match for the RX 7800 XT. Nonetheless, after reviewing the Radeon PRO W7800, I consider there’s a very good probability {that a} cutdown Navi 31 core may additionally take that place. Igor’s Lab has posted a radical evaluate of the Skilled card alongside projected scores of the supposed RX 7800XT.

The Radeon PRO W7800 is a workstation card primarily based on Navi 31. It’s a cutdown RX 7900 XT with 70 CUs, down from 96 CUs on the RX 7900 XTX. It additionally disables two MCDs, lowering the bus width to 256-bit and the Infinity cache to 64MB. Moreover, being a creator card, it comes with a comparatively decrease core clock of simply 1.85GHz (which might be elevated to 2.5GHz).

Igor totally examined the Radeon PRO W7800 as a simulated RX 7800 XT and located that the latter will possible be 10-15% quicker than the RX 6800 XT, 10-20% if you wish to be extra cautious. Apparently, the 7800XT fared one of the best in comparison with the RX 6800 XT at 4K, registering a mean acquire of 12.5%.

The Radeon RX 6800 XT averaged 59 FPS at 4K, whereas the RX 7800 XT averaged 66.4 FPS. Each GPUs are quicker than the NVIDIA GeForce RTX 4070, that means ray-tracing is sparingly neglected or used sparingly.

Relating to energy consumption, the RX 7800 XT is 20% extra environment friendly than the RX 6800 XT however can’t compete with the RTX 4070. It does handle to be extra environment friendly than the RTX 4070 Ti and the RTX 4080.

The 1440p benchmarks are extra CPU certain, leaving the RX 7800 XT with a lead of simply 8%. The RTX 4070 is as soon as once more slower than each Radeons on this benchmark, whereas the RX 7800 XT averages 118 FPS, simply south of the RTX 4070 Ti.

The first distinction between the RX 7800 XT and the W7800 considerations the core clocks. The Radeon will probably be clocked near 3GHz whereas the PRO runs beneath 2.5GHz. Although the clock deficit was thought-about, the ultimate efficiency could also be a couple of factors greater or decrease. Whatever the gen-over-gen uplift, the 7800 XT could also be an exceptional price range GPU.
