Well everyone knows that Intel has a big L2 cache but i noticed that it also has a small L1 cache. I noticed that AMD CPUs have a Large to medium size L2 cache and a medium size L1 cache.
My questions is: What is better to have more of and wat do both do?
This might b a stupid question but it has me confused.
I also went on Google on Wikipedia (i no the sources are not very reliable)
and i found this;
Quote"The advantage of exclusive caches is that they store more data. This advantage is larger when the exclusive L1 cache is comparable to the L2 cache, and diminishes if the L2 cache is many times larger than the L2 cache. When the L1 misses and the L2 hits on an access, the hitting cache line in the L2 is exchanged with a line in the L1. This exchange is quite a bit more work than just copying a line from L2 to L1, which is what an inclusive cache does.

The parts i underlined dont make sense at all and i wanted to ask u guys.
This has been puzzling me for a bit and if the underlined part means that if the L2 Cache is many times larger than the L1 cache then dose that mean that AMD is the smarter CPU company ???
