I think L1 cache seems good enough, and does not need to be that high. Maybe even 256KB. Togheter with a 200uS jitter target, the commonly used instructions will alleviate standard RAM where neccesary. A good CPU with an optimized instruction set for good use of cache and low jitter at 5ghz will be enough for most. Doing more pr. clock where optimal. This will give good bus timing. Meaning good GFX and Serving. Near realtime audio for audio also, that really with such a low-jitter setup safely can run realtime, avoiding audio dropouts.
