Question about Intel Core i9-7900X
on the other hand, i'm just wondering if the i9's 13 mb cache is in any way related to the use of ram. or does 64 mb ram make any difference at all if the i9 only has 13 mb cache? because the i9's cache can't work with more than 32 gb ram anyway? or am i fundamentally misunderstanding this?
This has nothing to do with each other. The Core i9-7900X supports a maximum of 128GB RAM. If the processor needs data for a calculation or processing, it first looks for this data in the small L1 cache, if not available it looks in the L2 cache and then in the L3 cache. If the data is not in any of these caches, it must be fetched from the much slower RAM.
The whole process is hierarchical:
L1: Small but very fast
L2: Larger and quite fast
L3: Larger but slower
RAM: even bigger but very slow (in relation to the cache)
Hard disk: even slower than RAM.
How much RAM makes sense depends on what the PC will be used for. 16GB is sufficient for games and "normal" work. By the way, the Core i9-7900X has four memory channels, i.e. 4 or 8 RAM modules should be installed for optimal performance.
