✔AMD Ryzen 9 3900X
✔Intel Core i7-10700K
Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.
L2 cache
A larger L2 cache results in faster CPU and system-wide performance.
L3 cache
A larger L3 cache results in faster CPU and system-wide performance.
L1 cache
A larger L1 cache results in faster CPU and system-wide performance.
L2 core
0.
5MB/core
0.25MB/core
More data can be stored in the L2 cache for access by each core of the CPU.
L3 core
5.33MB/core
2MB/core
More data can be stored in the L3 cache for access by each core of the CPU.
