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

Best for Gaming1 of 6

AMD Ryzen 7 9800X3D

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 box rules it out for your setup.
AMD Ryzen 7 9800X3D

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 Ryzen 7 7800X3D the nearest cheaper option.

Best Value X3D2 of 6

AMD Ryzen 7 7800X3D

The Ryzen 7 7800X3D has the same 96MB of L3 cache as its successor with an older core design and lower clocks.

Best for

Gamers who want 3D V-Cache without paying for the newest chip.

Skip if

Skip it if this is a deal-breaker for you: no cooler in the box.
AMD Ryzen 7 7800X3D

Why we like it

On the same AM5 socket, it is the way into X3D gaming for less. On boost clock it trails the group at 5GHz, while the Core Ultra 7 265K offers 5.5GHz. It matches the Ryzen 7 9800X3D on core count (8 cores).

It shares an AM5 socket with the Ryzen 7 9800X3D and Ryzen 5 9600X; the Core i5-14600K goes with an LGA1700 socket. It also offers first-generation AM5 3D V-Cache and the Zen 4 architecture. 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.

Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. Its price falls between the Core Ultra 7 265K and the Ryzen 7 9800X3D, based on our last check.

The catch

If boost clock is your priority, the Core Ultra 7 265K (5.5GHz) is the stronger choice.

Best Intel Pick3 of 6

Intel Core Ultra 7 265K

The Core Ultra 7 265K is Intel's strongest all-rounder here, with 20 cores for games plus background work, on the LGA1851 socket.

Best for

Builders who game and also run heavy multi-threaded work.

Skip if

Look at the others if this bothers you: no cooler in the box.
Intel Core Ultra 7 265K

Why we like it

It suits a builder who wants an Intel platform and a lot of multi-threaded headroom. Its 30MB L3 cache ranks fourth of 6 here, behind the Ryzen 7 9800X3D (96MB) and ahead of the Core Ultra 5 245KF (24MB). Nothing else here matches its 5.5GHz boost clock; the Ryzen 5 9600X comes closest at 5.4GHz.

Nothing else here matches its 20 cores core count; the Core i5-14600K comes closest at 14 cores. On rated power it ties with the Core i5-14600K and the Core Ultra 5 245KF at 125W. It also comes with 8 performance and 12 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 i5-14600K and cheaper picks cost less, and the Ryzen 7 7800X3D cost more.

Intel Core i5-14600K

Why we like it

Its 14 cores give good headroom for a mid-range gaming build. It boosts to 5.3GHz, and the unlocked multiplier allows overclocking on a Z-series board. It matches the Core Ultra 5 245KF on L3 cache (24MB).

Its 5.3GHz boost clock ranks third of 6 here, behind the Core Ultra 7 265K (5.5GHz) and ahead of the Ryzen 7 7800X3D (5GHz). On core count it ties with the Core Ultra 5 245KF at 14 cores. On rated power it ties with the Core Ultra 7 265K and the Core Ultra 5 245KF at 125W.

No other pick in this guide offers DDR4 or DDR5 memory; compare the Ryzen 7 7800X3D, which has DDR5 memory. It also comes with 6 performance and 8 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.

AMD Ryzen 5 9600X

Why we like it

It suits a budget build now that can take an X3D chip later without changing boards. Its 32MB L3 cache ranks third of 6 here, behind the Ryzen 7 9800X3D (96MB) and ahead of the Core Ultra 5 245KF (24MB). Its 5.4GHz boost clock ranks second of 6 here, behind the Core Ultra 7 265K (5.5GHz) and ahead of the Ryzen 7 7800X3D (5GHz).

On core count it trails the group at 6 cores, while the Core Ultra 7 265K offers 20 cores. Nothing else here matches its 65W rated power; the Ryzen 7 9800X3D comes closest at 120W. Like the Ryzen 7 9800X3D and Ryzen 7 7800X3D, it has an AM5 socket, while the Core i5-14600K uses an LGA1700 socket.

You also get the Zen 5 architecture. No other pick here cost less at our last price check, and the Core Ultra 5 245KF was closest.

The Core Ultra 5 245KF is the entry to LGA1851, with 14 cores and no integrated graphics.

Best for

Intel gaming builds on a budget with a graphics card.

Skip if

Skip it if this is a deal-breaker for you: no cooler in the box.
Intel Core Ultra 5 245KF

Why we like it

It needs a graphics card to show a picture, which every gaming build has anyway. It matches the Core i5-14600K on L3 cache (24MB). It matches the Ryzen 7 9800X3D on boost clock (5.2GHz).

On rated power it ties with the Core Ultra 7 265K and the Core i5-14600K at 125W. Like the Core Ultra 7 265K, it has an LGA1851 socket, while the Core i5-14600K uses an LGA1700 socket. 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. Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. It was priced above the Ryzen 5 9600X and below the Core i5-14600K at the time of writing.

Frequently Asked Questions

How does the Ryzen 5 9600X compare with the Core Ultra 7 265K on boost clock?

Between the top two, it is 5.5GHz on the Core Ultra 7 265K against 5.4GHz on the Ryzen 5 9600X, a 2% difference. The spread runs down to the Ryzen 7 7800X3D at 5GHz.

Which has the highest core count: the Core Ultra 7 265K or the Core i5-14600K?

The Core Ultra 7 265K tops core count at 20 cores; the Core i5-14600K follows at 14 cores, 43% apart. The Ryzen 5 9600X closes the ranking at 6 cores.

Which has the lowest rated power: the Ryzen 5 9600X or the Ryzen 7 9800X3D?

The Ryzen 5 9600X is lowest on rated power at 65W; the Ryzen 7 9800X3D follows at 120W, 46% apart. The Core Ultra 5 245KF is at the other end of this group with 125W.

What does the Ryzen 7 9800X3D add over the Ryzen 5 9600X?

The spec sheets show L3 cache (96MB against 32MB) and core count (8 cores against 6 cores) in its favour. It does not win everywhere: the Ryzen 5 9600X still leads on boost clock (5.4GHz) and rated power (65W). On our last price check the Ryzen 5 9600X was in the $150 to $250 tier and the Ryzen 7 9800X3D in the $250 to $500 tier, with 4 other picks between them; pay the difference only if L3 cache and core count decide your purchase.

Why is the Ryzen 7 7800X3D our Best Value X3D pick?

It carries the badge for the same 96MB L3 cache as the 9800X3D at a lower boost clock. The price of that: the Ryzen 5 9600X, the cheapest pick, still beats it on boost clock (5.4GHz against 5GHz) and rated power (65W against 120W). It makes sense for anyone who wants 3D V-Cache without paying for the newest chip.

Do the Ryzen 7 9800X3D and the Core Ultra 7 265K differ on socket?

The Ryzen 7 9800X3D, the Ryzen 7 7800X3D and the Ryzen 5 9600X use AM5; the Core Ultra 7 265K and the Core Ultra 5 245KF use LGA1851; the Core i5-14600K uses LGA1700.

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.
