The VCS had the CPU calculate graphics and then place them into into
shift registers.

The shift registers would need to run at 8mhz, you would need 9 shift
registers (8 sprite + 1 text).

The 6502 fetching the data may need to run faster than 8mhz, because of
all the extra work calculating addresses, fetching and storing data.
