The Best CPUs With High Clock Speeds

Check your board has the latest BIOS for Intel's stability microcode. On L3 cache it ties with the Core Ultra 9 285K at 36MB. Nothing else here matches its 6GHz boost clock; the Core Ultra 9 285K comes closest at 5.7GHz.

An LGA1700 socket is unique to it among these picks, while the Core Ultra 9 285K uses an LGA1851 socket. You get DDR4 or DDR5 memory here, which sets it apart from the Ryzen 9 7900X3D and its DDR5 memory. It also offers 8 performance and 16 efficient cores.

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. On price it sat second of 4, between the cheaper Ryzen 7 9700X and the pricier Core Ultra 9 285K, at the time of writing.

It suits competitive players who also stream from the same machine. It matches the Core i9-14900K on L3 cache (36MB). Its 5.7GHz boost clock ranks second of 4 here, behind the Core i9-14900K (6GHz) and ahead of the Ryzen 9 7900X3D (5.5GHz).

On rated power it ties with the Core i9-14900K at 125W. It is the only pick here with an LGA1851 socket; the Ryzen 7 9700X has an AM5 socket instead. Like the Ryzen 7 9700X and Ryzen 9 7900X3D, it has DDR5 memory, while the Core i9-14900K uses DDR4 or DDR5 memory.

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. When we checked, only the Core i9-14900K and cheaper picks cost less, and the Ryzen 9 7900X3D cost more.

It is the quieter, cooler-running choice when a build balances games with everyday work. On L3 cache it trails the group at 32MB, while the Core i9-14900K offers 36MB. On boost clock it ties with the Ryzen 9 7900X3D at 5.5GHz.

Its 8 cores core count is the lowest in this group; the Core i9-14900K leads at 24 cores. Nothing else here matches its 65W rated power; the Core i9-14900K comes closest at 125W. It shares an AM5 socket with the Ryzen 9 7900X3D; the Core Ultra 9 285K goes with an LGA1851 socket.

You also get the Zen 5 architecture. It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; a 600-series board may need a BIOS update first, so check the maker's CPU support list for the minimum version. It was the cheapest of the group when we checked; the Core i9-14900K was the next step up.

On the spec sheet, it offers a 5.5GHz boost clock and offers a 12 cores core count. It matches the Ryzen 7 9700X on boost clock (5.5GHz). On core count it sits mid-pack at 12 cores: the Core i9-14900K offers 24 cores, and the Ryzen 7 9700X comes in at 8 cores.

Like the Ryzen 7 9700X, it has an AM5 socket, while the Core i9-14900K uses an LGA1700 socket. It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; check the board's CPU support list for the minimum BIOS version. No cooler is included; a single-tower air cooler is enough at its rating. Only the Core Ultra 9 285K came close to it on price at the time of writing; it cost the most of the 4 picks.
