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 The PC Journal editorial team
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.

Largest Game Cache1 of 6
AMD Ryzen 7 9850X3D on Amazon (opens in a new tab)
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 bo 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.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Platform cost
- We noted socket, memory type and whether a cooler is included, since they change the real price.
- Power and cooling
- We recorded each chip's rated power and what cooler class it needs.
- Upgrade path
- We considered how long each socket is likely to receive new CPUs.
- Game-relevant specs
- We compared L3 cache, boost clocks and core counts from AMD's and Intel's product pages.
What to Look for in a CPUs for 240Hz Gaming
Key buying criteria so you get the right fit the first time.
Cache helps games more than clocks
AMD's X3D chips add a large stacked L3 cache that keeps more game data close to the cores. In CPU-limited games that often helps more than a higher boost clock.
The gain shrinks when the graphics card is the limit.
Match the CPU to your graphics card and monitor
At 1440p and 4K the graphics card sets most frame rates, so a mid-range CPU is often enough. At 1080p with a high-refresh monitor, the CPU matters much more.
Spend on the part that limits your games, not on the bigger number.
Integrated graphics are a useful backup
Chips with integrated graphics can drive a display without a graphics card, which helps when troubleshooting or between upgrades. Intel's F and KF models and most AM4 Ryzen chips have none.
Budget for the cooler
Most unlocked chips ship without a cooler. A 65W part runs well on a basic single tower, while 120W to 170W parts need a dual tower or an AIO to hold their boost clocks.
Add the cooler to the CPU price when comparing.
The socket decides your upgrade path
The socket fixes which motherboards and future CPUs you can use. AM5 has had several CPU generations; AM4 has no newer chips coming.
If you plan to upgrade later, a current platform is worth a small premium.
Check BIOS support before buying
Newer CPUs on older boards may need a BIOS update before the system will start. Check the board's CPU support list for the version you need and whether the board can flash without a CPU installed.

Frequently Asked Questions
Will a new CPU work in my current motherboard?
Only if the socket matches and the board's BIOS supports it. Check the maker's CPU support list for the minimum BIOS version.
What does the rated power figure mean?
It is AMD's default TDP or Intel's base power. Chips can draw more under boost, so size the cooler for sustained loads, not the label alone.
What does X3D mean on a Ryzen CPU?
It marks AMD's 3D V-Cache chips, which stack extra L3 cache on the processor. Games that are limited by the CPU tend to run faster on them.
What memory should I pair with it?
AM5 and LGA1851 use DDR5; AM4 uses DDR4. For AM5, a 32GB DDR5-6000 kit is a common pairing; check the board's memory support list.
Is AM4 still worth buying into?
For an upgrade to an existing AM4 system, yes. For a new build, AM5 or LGA1851 gives a longer upgrade path.
Do I need to buy a separate cooler?
Usually yes. Only some chips, such as the Ryzen 5 7600 and 5600X, include a basic cooler; unlocked high-end models do not.
Bottom Line
The Ryzen 7 9850X3D is the pick for the highest frame rates, and the Core Ultra 9 285K and Core i7-14700K are the Intel options with room for streaming.
The Ryzen 7 7700X, Ryzen 5 9600X and Ryzen 5 7600X reach high refresh rates in esports titles for less.
