[SOLVED] CPU Cache Size to Performance

[Seabass101]

Hi, Why aren’t the L1 and L2 cache sizes not getting any bigger with new CPUs especially in 2020 and beyond?

Would it not help with the performance if you increased L1 and L2 by a little or to the next size amount?

lastly, why are 8 cores 16 thread CPUs L1 and L2 kind of low of a size for cpus now a days?

Thx
Respectfully, Sebastian

The issue is size. A CPUs cache is Sram, unlike system memory. Sram is very fast, hence its use in the cache.

However, Sram is very expensive and the Sram chips themselves are very small capacity. Making larger capacity SRAM chips would require larger/more chips and a long wire is a slow wire.

So size and price are the main factors why
