We are at the perfect moment to re-embrace software rasterizers because CPU manufacturers are starting to add HBM and v-cache.
An 8K 32bpp framebuffer is ... omg 126MB for a single copy. I was going to argue that a software rasterizer running on vcache would be doable, but not for 8k.
For 4k, with 32MB per display buffer, it could be possible but heavy compositing will require going out to main memory. 1440p would be even better at only 15MB per display buffer.
For 1440p at 144Hz and 2TB/s (vcache max), best case is an overdraw of 984 frames/frame
