The Best CPUs for 240Hz Competitive Gaming
Six CPUs for 240Hz esports gaming compared on cache, boost clock, cores and platform, where the CPU sets the frame-rate ceiling.
By Alex Morgan, PC Hardware Editor
12 min read6 products evaluated

At 240Hz, many competitive games are limited by the CPU rather than the graphics card, especially at 1080p with lowered settings. Cache and single-threaded speed matter more here than core count.
We compared six CPUs on cache, boost clock, cores and platform. This is a research-based comparison built from maker specifications; we did not test these parts ourselves.

Our Picks
Largest Game Cache1 of 6
AMD Ryzen 7 9850X3D
The Ryzen 7 9850X3D combines AMD's 96MB of L3 cache with the highest clocks of the eight-core X3D chips.
Best for
- Players chasing 1% lows in simulation and esports titles.
Skip if
- Pass on it if no cooler in the box rules it out for your setup.
Why we like it
For competitive games that run far above 144Hz, it is the chip most likely to keep frame times steady. Nothing else here matches its 96MB L3 cache; the Core Ultra 9 285K comes closest at 36MB. It matches the Core i7-14700K on boost clock (5.6GHz).
On core count it ties with the Ryzen 7 7700X at 8 cores. On rated power it sits mid-pack at 120W: the Ryzen 5 9600X offers 65W, and the Core Ultra 9 285K comes in at 125W. It also comes with a higher-clocked take on the 9800X3D design.
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 priced above the Core i7-14700K and below the Core Ultra 9 285K at the time of writing.
