- 486s have a built-in small cache (L1 cache). Additionally, there may be a
- larger (e.g. 256 K) external cache called L2 cache. Some systems are
- shipped with EDO RAM instead - many notebooks use EDO RAM instead of a
- power-consuming L2 cache. EDO systems without a L2 cache usually are slower
- than L2 designs. Pentiums have built-in L1 & L2 caches, thus the L2 cache
- can run at CPU clock rate.
