12 min read5 products evaluated
Compiling and running containers use many cores without needing a flagship. Every pick has eight or more cores at 125W or less and cost $350 or less.
The order reflects L3 cache, max boost and cores / threads from maker specifications; gaps in the specs are flagged, not filled in rather than guess, since we have not benched them.

Our Picks
Largest Game Cache1 of 5
Intel Core i7-14700KF
The Core i7-14700KF is the 14700K without integrated graphics.
Best for
- Games that are limited by the CPU at high frame rates.
Skip if
- Pass on it if no cooler in the box rules it out for your setup.
Why we like it
It suits a gaming PC that already has a graphics card. Its 33MB L3 cache is the largest here; the Core Ultra 7 265KF comes next at 30MB. Its 5.6GHz boost clock is the highest here; the Core Ultra 7 265KF comes next at 5.5GHz.
On core count it ties with the Core Ultra 7 265KF at 20 cores. Like the Core i5-14600KF and Core i5-13600K, it has an LGA1700 socket, while the Core Ultra 7 265KF uses an LGA1851 socket. You also get 8 performance and 12 efficient cores and an unlocked multiplier.
It fits LGA1700 boards (600 and 700 series) with either DDR4 or DDR5, depending on the board; 600-series boards may need a BIOS update for 14th-gen chips. Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. When we checked, only the Core i5-14600KF and cheaper picks cost less, and the Core Ultra 7 265KF cost more.

How We Chose
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- The figures behind the order
- We lined up five processors on L3 cache, boost clock, core count and rated power as the makers state them. These are research figures, not bench results, and every compared field is stated for all 5 picks.
- What every pick has in common
- All 5, from the Core i7-14700KF to the Core i5-13600K, state L3 cache, boost clock and core count.
- Who each pick suits
- The Core i7-14700KF for the largest L3 cache here (33MB); the Core Ultra 7 265KF for 8 performance and 12 efficient cores; the Core Ultra 5 245KF for undercutting the Core i5-14600KF on price when we checked.
- Price range
- At our last check the picks ran from the Core Ultra 5 245KF ($150 to $250) to the Core i5-13600K ($250 to $500).
What to Look for in a CPUs for Programming
Key buying criteria so you get the right fit the first time.
L3 cache across these picks
Across these 5 picks L3 cache spans 24MB (the Core i5-13600K) to 33MB (the Core i7-14700KF). Start with the Core i7-14700KF if L3 cache decides it.
How much boost clock you need
The Core i7-14700KF tops boost clock at 5.6GHz and the Core i5-13600K sits lowest at 5.1GHz. If boost clock is your first filter, the Core i7-14700KF sets the ceiling at 5.6GHz.
An Intel stock cooler mounted over the CPU socket inside a PC How much core count you need
Here core count runs from 14 cores on the Core i5-13600K to 20 cores on the Core i7-14700KF, a 43% spread. If core count is your first filter, the Core i7-14700KF sets the ceiling at 20 cores.
Memory
The Core i7-14700KF, the Core i5-14600KF and the Core i5-13600K list DDR4 or DDR5; the Core Ultra 7 265KF and the Core Ultra 5 245KF list DDR5.
Cooler in box
The Core i7-14700KF, the Core Ultra 7 265KF, the Core Ultra 5 245KF, the Core i5-14600KF and the Core i5-13600K go without. Sort out cooler in box before price: it splits 5 stated picks into groups of 5.
