by Geekvolcano / August 18, 2007 10:02 PM PDT

Hello Guys,

What can be a place to ask PC related question then CNET Happy


What I want to know is the difference between:

1x1MB L1 Cache on CPU &
2MB L1 Cache on CPU.

Although I know by architecture there is some difference but donno what's that is. I hope someone would reply in details to help other PC Geeks.

Thanks in Advance.

I'd like to see a CPU with 1MB L1...so far I don't think anything but (maybe) vector processors use this...

Cache is on-die or on-package memory to increase CPU performance, the L1 cache is usually very small (64k or less) while the L2 cache can get quite large (up to 3-4MB in some cases) and L3 caches can be massive (upwards of 20MB in some cases, although not all CPUs have L3)

So, do you have a more specific question? Such as two CPUs you're trying to compare?

Get benchmarks on your proposed systems. If L1 Cache made a system you would see it prominently listed at the top of the list. Don't fixate on just this but find the benchmarks.
