Cache on the CPU is very important, because it's the read ahead memory. It operates as fast as the CPU, which is much faster than the RAM. The more data that can be moved into the cache in the same amount of time gives the CPU the best chance at utilizing it's potential. Enough RAM is important, but less so than cache.

Cache is a super fast type of memory known as SRAM. Since it is very fast and expensive it is only used on CPUs as L1 and L2 cache.
Both types of memory are important for performance in different ways. Cache affects the raw speed of your computer. RAM affects how fast your computer runs while multitasking.
The important thing to remember is if you are buying a new computer, you can upgrade the RAM later, but the cache is built into your processor and can't be upgraded without buying a new processor.

They both affect speed. Cache is usually very close (physically) to the processor... Think of your cache as a 'super ram'.... Your computer looks to cache first - if it can't find it - it goes to ram - so the more cache, the faster - but the more ram the faster too..... so in computers - the old saying "more is better' really applies.

There serve difference purposes. In my experience I find RAM has more direct impact on the computers performance.
