Uh oh. This has that "all games will output at 1080p" fiasco written all over it.
Nope! It just means you will be running 1080p at 120FPS. Noticed resolution was mentioned for either FPS. ;)
Example of XSX vs X1X
From https://www.tomsguide.com/news/first-xbox-series-x-gameplay-may-be-revealed-today-with-forza-motorsport-8
Forza Horizon 4
The demo show will reportedly continue with Forza Horizon 4. Here we will see how variable rate shading works on the Xbox Series X. VRS is a technique that allows the GPU to boost detail and quality in complex parts of the images while lowering its power needs in simpler areas.
The reasoning behind VRS is that our eyes and brain can’t focus on the totality of an image. If you are paying attention to the screen, your eyes will be focused on where the action is, which typically is the more complex part of the image. The graphics engine doesn’t have to spend so much power on the less complex, peripherals parts of the image. That results in power optimization that allows to boost detail even more or increase the frame rate.
The results? Playground Games — who develop the Forza Horizon series — added VRS to Forza Horizon 4 when it received its Xbox Series X development kits in December. That increased the frame rate in the game by a whooping 32% with “no optimizations, just using VRS in parts with motion blur.” According to the redditor, “VRS changes the way they design games (VRS as motion blur replacement),” pointing out that the” lead engineer says they can reach 4K/120 today on XSX thanks to RDNA2 architecture and the combined effort of AMD and Microsoft.”
Yeah, 4K and 120 frames per second.
Swapping FH4's blur motion into VRS version enables XSX's FH4 to reach 120 fps 4K.
If VRS improves the frame rate by 32 percent which yields 120 fps 4K, then non-VRS version would be 81.6 fps 4K, hence XSX GPU is about 2.72 times better than X1X GPU's FH4 results.
The "no optimizations" could mean running on GCN legacy mode (wave64 instructions) instead of RDNA mode (wave32 instructions)
When running on GCN legacy mode, XSX GPU is effectively ~16.3 TFLOPS GCN.
