The Best CPUs for Gaming

Six gaming CPUs from AMD and Intel compared on cache, cores, boost clock, platform and cooling needs, from X3D chips to budget six-cores.

By The PC Journal editorial team

12 min read6 products evaluated

For games, the CPU decides how high frame rates can go once the graphics card is no longer the limit. Large L3 cache helps many games more than extra cores, which is why AMD's X3D chips lead most gaming comparisons.

We compared six CPUs on cache, cores, clocks, socket and cooler requirements. This is a research-based comparison built from maker specifications; we did not test these parts ourselves.

Pick the platform first: AM5 and LGA1851 are current sockets, while LGA1700 suits upgraders who already own a board.

Our Picks

AMD Ryzen 7 9800X3D

Best for Gaming1 of 6

AMD Ryzen 7 9800X3D on Amazon (opens in a new tab)

The Ryzen 7 9800X3D pairs AMD's 3D V-Cache with eight Zen 5 cores, and games that lean on cache respond to it more than to extra cores.

Best for

High-refresh gaming with a fast graphics card.

Skip if

Pass on it if no cooler in the bo rules it out for your setup.

Why we like it

It is the chip to pair with a high-end graphics card when the CPU would otherwise hold frame rates back. It matches the Core Ultra 5 245KF on boost clock (5.2GHz). On core count it ties with the Ryzen 7 7800X3D at 8 cores.

Like the Ryzen 7 7800X3D and Ryzen 5 9600X, it has an AM5 socket, while the Core Ultra 7 265K uses an LGA1851 socket. It also offers second-generation 3D V-Cache placed under the cores and an unlocked multiplier, a first for AMD's X3D chips. 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.

Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. At our last price check it topped the group, with the Core Ultra 7 265K the nearest cheaper option.

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.
Upgrade path
We considered how long each socket is likely to receive new CPUs.
Power and cooling
We recorded each chip's rated power and what cooler class it needs.
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 Gaming

Key buying criteria so you get the right fit the first time.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. Cores matter for streaming and creation

    Six and eight cores cover gaming. Streaming with CPU encoding, video editing and compiling benefit from twelve or sixteen.

    If you encode on the graphics card instead, core count matters less.

Frequently Asked Questions

Should I choose Intel or AMD for gaming?

At the high end, AMD's X3D chips lead in many CPU-limited games. Intel's Core Ultra chips offer more cores for work at similar prices. Choose by workload and platform cost.

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.

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.

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.

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.

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.

Bottom Line

The Ryzen 7 9800X3D is the strongest gaming pick, and the 7800X3D delivers the same cache for less. The Core Ultra 7 265K is the Intel choice for mixed gaming and heavy work.

The Ryzen 5 9600X and Core Ultra 5 245KF are the budget entry points on current sockets, and the Core i5-14600K suits LGA1700 upgraders.
