The N64's unified memory model had a pretty big asterisk though. The system had only 4kB for textures out of 4MB of total RAM. And textures are what uses the most memory in a lot of games.
- klodolph 4y agoThat’s a somewhat misleading way to describe it. The N64 has 4K texture memory (TMEM), but you can use far more than 4K of texture during a frame—because you can load data into TMEM as many times as you like during a frame. In practice, you might think of TMEM like it’s a cache, it’s just that you have to manage this cache manually. You can use as much RAM as you like for textures. TMEM is also not part of main RAM, like the RSP’s DMEM and IMEM.
