The Best Intel Core Ultra CPUs for Gaming
From the Core Ultra 5 225F to the Core Ultra 9 285K: four processors ranked on L3 cache and boost clock, with who should skip each one.
By Alex Morgan, PC Hardware Editor
11 min read4 products evaluated
Core Ultra 200S chips moved Intel to the LGA1851 socket and DDR5 only. Every pick is a Core Ultra processor, ordered by core count.
We sorted these picks by L3 cache, max boost and cores / threads, working from the makers' own data; nothing here was tested in-house, and if a maker skips rated power, the guide says so.

Our Picks
Largest Game Cache1 of 4
Intel Core Ultra 9 285K
The Core Ultra 9 285K is Intel's flagship on LGA1851, with 24 cores and high single-threaded clocks.
Best for
- Players chasing 1% lows in simulation and esports titles.
Skip if
- Look at the others if this bothers you: no cooler in the box.
Why we like it
It suits competitive players who also stream from the same machine. Nothing else here matches its 36MB L3 cache; the Core Ultra 7 265KF comes closest at 30MB. Its 5.7GHz boost clock is the highest here; the Core Ultra 7 265KF comes next at 5.5GHz.
Its 24 cores core count is the highest here; the Core Ultra 7 265KF comes next at 20 cores. It also comes with 8 performance and 16 efficient cores and a built-in NPU for AI features. It needs an LGA1851 board (Intel 800-series chipset) and DDR5 memory; LGA1700 boards and coolers without an LGA1851 mounting kit will not fit.
Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. It was the highest-priced of the 4 picks at the time of writing, so the case for it rests on what it adds over the Core Ultra 7 265KF and the rest.

Also Consider2 of 4
Intel Core Ultra 7 265KF
The Core Ultra 7 265KF is the 265K without integrated graphics.
Best for
- Buyers who want 8 performance and 12 efficient cores.
Skip if
- Pass on it if no cooler in the box rules it out for your setup.
Why we like it
It costs less and needs a graphics card for any display output. On L3 cache it sits mid-pack at 30MB: the Core Ultra 9 285K offers 36MB, and the Core Ultra 5 225F comes in at 22MB. On boost clock it sits mid-pack at 5.5GHz: the Core Ultra 9 285K offers 5.7GHz, and the Core Ultra 5 225F comes in at 4.9GHz.
Its 20 cores core count ranks second of 4 here, behind the Core Ultra 9 285K (24 cores) and ahead of the Core Ultra 5 225F (10 cores). It also comes with 8 performance and 12 efficient cores and an unlocked multiplier. It needs an LGA1851 board (Intel 800-series chipset) and DDR5 memory; LGA1700 boards and coolers without an LGA1851 mounting kit will not fit. On price it sat third of 4, between the cheaper Core Ultra 5 245KF and the pricier Core Ultra 9 285K, at the time of writing.

Strong Alternative3 of 4
Intel Core Ultra 5 245KF
The Core Ultra 5 245KF is the entry to LGA1851, with 14 cores and no integrated graphics.
Best for
- Buyers who want 6 performance and 8 efficient cores.
Skip if
- Look at the others if this bothers you: no cooler in the box.
Why we like it
It needs a graphics card to show a picture, which every gaming build has anyway. On L3 cache it sits mid-pack at 24MB: the Core Ultra 9 285K offers 36MB, and the Core Ultra 5 225F comes in at 22MB. On boost clock it sits mid-pack at 5.2GHz: the Core Ultra 9 285K offers 5.7GHz, and the Core Ultra 5 225F comes in at 4.9GHz.
Its 14 cores core count ranks third of 4 here, behind the Core Ultra 9 285K (24 cores) and ahead of the Core Ultra 5 225F (10 cores). It also comes with 6 performance and 8 efficient cores, Intel 800-series chipset support and PCIe 5.0 support. It needs an LGA1851 board (Intel 800-series chipset) and DDR5 memory; LGA1700 boards and coolers without an LGA1851 mounting kit will not fit. Its price falls between the Core Ultra 5 225F and the Core Ultra 7 265KF, based on our last check.

Lowest Price Here4 of 4
Intel Core Ultra 5 225F
The Core Ultra 5 225F is a locked ten-core LGA1851 chip.
Best for
- Buyers who would rather put the savings elsewhere than into the Core Ultra 5 245KF.
Skip if
- Choose another pick if you can't accept this: no integrated graphics, so a graphics card is required.
Why we like it
It suits a budget Intel build that will pair with a B860 board. On L3 cache it trails the group at 22MB, while the Core Ultra 9 285K offers 36MB. On boost clock it trails the group at 4.9GHz, while the Core Ultra 9 285K offers 5.7GHz.
Its 10 cores core count is the lowest in this group; the Core Ultra 9 285K leads at 24 cores. You also get 6 P-cores plus 4 E-cores and PCIe 5.0 and 4.0 support on Intel 800-series boards. It needs an LGA1851 board (Intel 800-series chipset) and DDR5 memory; LGA1700 boards and coolers without an LGA1851 mounting kit will not fit. It undercut the Core Ultra 5 245KF and every other pick on price at the time of writing.

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 set side by side four processors on L3 cache, boost clock, core count and rated power from manufacturer specifications. We did not test them in-house, and rated power and threads are missing for at least one pick.
- The shared baseline
- All 4, from the Core Ultra 9 285K to the Core Ultra 5 225F, state L3 cache, boost clock and core count and share LGA1851 socket.
- Where the specs have gaps
- The Core Ultra 5 225F gives no rated power; the Core Ultra 5 225F gives no threads.
- Price range
- At our last check the picks ran from the Core Ultra 5 225F ($100 to $150) to the Core Ultra 9 285K ($500 to $1000).
