The Best CPUs for Minecraft
From the Core i7-14700KF to the Core i9-14900K: three processors ranked on L3 cache and boost clock, with who should skip each one.
By The PC Journal editorial team
11 min read3 products evaluated
Minecraft is mostly single-thread limited, so a high boost clock helps with big worlds and mods. Every pick boosts to 5.5GHz or more, ordered from the lowest price.
This is a research roundup, not a lab test: L3 cache, max boost and cores / threads come from each maker's published specs; nothing here was tested in-house, and gaps in the specs are flagged, not filled in.

The Core i7-14700KF is the 14700K without integrated graphics.
Best for
- Getting 8 performance and 12 efficient cores for the least money.
Skip if
- Choose another pick if you can't accept this: no cooler in the box.
Why we like it
It suits a gaming PC that already has a graphics card. On L3 cache it trails the group at 33MB, while the Ryzen 9 7900X offers 64MB. On boost clock it ties with the Ryzen 9 7900X at 5.6GHz.
Its 20 cores core count ranks second of 3 here, behind the Core i9-14900K (24 cores) and ahead of the Ryzen 9 7900X (12 cores). It matches the Core i9-14900K on rated power (125W). It shares an LGA1700 socket with the Core i9-14900K; the Ryzen 9 7900X goes with an AM5 socket.
It also comes with 8 performance and 12 efficient cores and an unlocked multiplier.
