The Radeon RX 7800 XT emulates slightly better than the RX 6800 XT

The future of the Radeon RX 7800 XT is still shrouded in mystery. AMD has not yet officially confirmed the model, but it is expected that it will be based on a scaled-down version of the same circuit. However, the thing that really exists is the professionally oriented Radeon Pro W7800, which can be used when Igor Lab Simulates how the RX 7800 XT performs.

Igor’s Lab uses two different testing methods, one of which is based on the Radeon Pro W7800 which is artificially limited to just 16 of the total 32GB of GDDR6 memory. The simulated results place themselves between the RX 6800 XT and RX 6900 XT predecessors. Against the competition in the green team, it’s close to a level between the RTX 4070 and RTX 4070 Ti, at least in terms of point-and-shoot performance in games.

The Radeon Pro W7800 is also based on Navi 31, but it has been expanded from 96 compute units to 70. The memory bus is the same 256-bit variant the RX 7800 XT is rumored to have, and by artificially restricting the graphics card to use only 16 of its 32GB total, it’s similar on paper.

Energy efficiency could be the biggest difference

However, they are adapted for completely different areas of use where, for example, energy efficiency is much more important than clock frequencies. It’s not fundamentally optimized for the total of nine games that make up the basis of the test, and Igor’s Lab is careful to point out that the results should only be seen as a rough estimate. However, he notes that one of the main differences in the RX 7800 XT compared to the previous generation is its energy efficiency, with simulations showing significant improvements.
