Scumbria,

It takes longer to retrieve data from an off-chip device, than it does from an on-chip device. This is because it takes a large number of clocks to synchronize the bus, send the request on an external bus, and retrieve the data back.

Thanks. Sorry to take you back to cache 101.

What would be lost with a larger, slower on-chip cache vs a smaller, faster on-chip cache? For the comparison, suppose that the slower cache was 10X bigger or more.

wily
