RTX 5080 Advantages vs RTX4080.

2x number of integer pipelines per cuda core:

• A lot better decompression performance
• Slight boost in raster
• Boost in game logic (when parallelized to run in gpu instead of cpu)
• Those games/apps that are not using integer at all will make gpu frequency boost to 3500MHz.

Much better tensor core performance:

• DLSS4 performance
• Professional work with training / inference
• Some image processing that uses matrix multiplication

Nice memory bandwidth boost:

• Nearly everything benefits, games, render farms, mining, etc.
• Higher gpu overclock scaling

PCie v5.0:

• 2x bandwidth to move data between RAM and VRAM

Some games can do this in future:

• Copy 1GB texture through pcie v5 in 15 milliseconds
• Decompress to 2GB in 4 milliseconds
• Use the extra 2GB decompressed texture on top of other 16GB used earlier
• 19 milliseconds overhead per frame for 18GB VRAM usage as 16 + 2, at 50 FPS if decompression overlaps with rendering of an earlier frame with similar latency.

There's also bigger RT core performance which can be used for computing collisions between rays and objects where rays are velocity vectors of objects, to calculate car collisions much faster than BeamNG does.
