  ✔Intel Core i7-7740X

  ✔Intel Core i7-8700K

  Some processors come with an unlocked multiplier and are easier to overclock, allowing for better performance in games and other applications.

  L2 Cache

  More L2 scratchpad memory results in faster results in CPU and system performance tuning.

  L3 cache

  More L3 scratchpad memory results in faster results in CPU and system performance tuning.

  L1 cache

  More L1 cache results in faster results in CPU and system performance tuning.

  L2 core

  1MB/core

  0.25MB/core

  More data can be stored in L2 scratchpad for access by each processor core.

  L3 core
