As for some justification for my category choices:
The top portion here is the current category limits, the average PPD based on the PPD database, and the highest grossing WU's based on the database.
The bottom portion is my proposed change, based on numbers from the database.
By increasing the Upper limit of GPU-O and GPU-L, there will not be as significant of a gap between the 2 categories. I expect there to be an overlap until we can get proper hardware slotted into GPU-O.
AMD remains unchanged, until we can get more info about the Vega 56/64/FE GPUs.
nVidia's upper limit has been raised to match the AMD category. This way teams can remain a bit more competitive cross categories.
GPU-W's upper limit has been raised to match the former nVidia category. This should
put PPD close to what 16C/32T CPU's can put out these days.
