Absolutely. But there are limitations due to how far away the system memory is from the CPU.
You're overthinking it. Cache is SRAM memory, which is much faster and less capacity than DRAM.
Also cache is built directly next to the CPU cores themselves which drastically reduces access latency.
Even with hyper fast system memory, cache will always have lower latency because of it's proximity to the CPU.
Increasing the cache capacity does increase latency as it takes longer to access the data, but it's still far less latency than accessing system memory.
That's precisely why V-cache provides such a significant increase in game performance. Anything that gets data to the CPU faster is going to increase performance.
Yeah that makes sense cache is SRAM and closer to much faster access. Though how come some apps do worse on 5800X3D than regular 580X. Is it only do to faster boost clock speeds on regular 5800X? If the clock speeds were always equal would the 580X3D always beat the regular 5800X or certainly never lose to it due to much larger cache??
And how about the extra L3 cache in Raptor Lake 13900K being 36MB instead of 30MB and 25MB on 12900K and 12700K. Will that make a big difference in reducing or eliminating potential gaming bottlenecks and allow it compete with Ryzen 7000X3D CPUs for smooth and strong 1% and 0.1% lows of FPS? This of course means e-waste cores are disabled so the 8 P cores have full access all the time to the L3 cache. Or is another 6-11MB of L3 cache to insignificant. Cause I do notice Intel scales their L3 cache size with more e-waste cores.
