Highest Boost Clock1 of 5
Intel Core i9-14900K on Amazon (opens in a new tab)
The Core i9-14900K is the last LGA1700 flagship with a 6.0GHz boost clock.
Best for
- Buyers who put boost clock first.
Skip if
- Skip it if this is a deal-breaker for you: no cooler in the box.
Why we like it
Check your board has the latest BIOS for Intel's stability microcode. It matches the Core Ultra 9 285K on L3 cache (36MB). On boost clock it leads this guide at 6GHz, ahead of the Ryzen 9 9950X (5.7GHz).
On core count it ties with the Core Ultra 9 285K at 24 cores. It is the only pick here with an LGA1700 socket; the Ryzen 9 9950X has an AM5 socket instead. No other pick in this guide offers DDR4 or DDR5 memory; compare the Ryzen 9 7900X, which has DDR5 memory.
You also get 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. When we checked, only the Ryzen 9 7900X and cheaper picks cost less, and the Ryzen 9 9950X cost more.

Also Consider2 of 5
AMD Ryzen 9 9950X on Amazon (opens in a new tab)
The Ryzen 9 9950X gives 16 cores and 32 threads without the X3D premium.
Best for
- Buyers who want AMD's recommendation of a liquid cooler.
Skip if
- Choose another pick if you can't accept this: 170W rating calls for a large air cooler or a 280mm-plus AIO.
Why we like it
It is the better buy when CPU encoding and editing matter more than the last few frames per second. It matches the Ryzen 9 7900X on L3 cache (64MB). It matches the Core Ultra 9 285K on boost clock (5.7GHz).
On core count it sits mid-pack at 16 cores: the Core i9-14900K offers 24 cores, and the Ryzen 5 9600X comes in at 6 cores. On rated power it ties with the Ryzen 9 7900X at 170W. Like the Ryzen 9 7900X and Ryzen 5 9600X, it has an AM5 socket, while the Core i9-14900K uses an LGA1700 socket.

Premium Pick3 of 5
Intel Core Ultra 9 285K on Amazon (opens in a new tab)
The Core Ultra 9 285K is Intel's flagship on LGA1851, with 24 cores and high single-threaded clocks.
Best for
- Spending more for the fullest feature set.
Skip if
- Look at the others if this bothers you: no cooler in the box.
Why we like it
It suits competitive players who also stream from the same machine. On L3 cache it ties with the Core i9-14900K at 36MB. On boost clock it ties with the Ryzen 9 9950X at 5.7GHz.
It matches the Core i9-14900K on rated power (125W). An LGA1851 socket is unique to it among these picks, while the Ryzen 9 9950X uses an AM5 socket. You also get 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. Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the Ryzen 9 9950X and the rest.

Best for
- Buyers who want Zen 4 architecture.
Skip if
- Look at the others if this bothers you: 170W rating calls for a large air cooler or a 280mm-plus AIO.
Why we like it
It is a cheaper way to the same thread count as the 9900X, at a higher power rating. It matches the Ryzen 9 9950X on L3 cache (64MB). Its 5.6GHz boost clock ranks fourth of 5 here, behind the Core i9-14900K (6GHz) and ahead of the Ryzen 5 9600X (5.4GHz).
On core count it sits mid-pack at 12 cores: the Core i9-14900K offers 24 cores, and the Ryzen 5 9600X comes in at 6 cores. On rated power it ties with the Ryzen 9 9950X at 170W. Like the Ryzen 9 9950X and Ryzen 5 9600X, it has an AM5 socket, while the Core i9-14900K uses an LGA1700 socket.
It also comes with the Zen 4 architecture, a 5nm process and PCIe 5.0 support on AM5. It was priced above the Ryzen 5 9600X and below the Core i9-14900K at the time of writing. It gives ground on rated power, where the Ryzen 5 9600X offers 65W.

Lowest Rated Power5 of 5
AMD Ryzen 5 9600X on Amazon (opens in a new tab)
The Ryzen 5 9600X brings six Zen 5 cores to AM5 at a 65W rating, which keeps cooling simple.
Best for
- Buyers who put rated power first.
Skip if
- Choose another pick if you can't accept this: 6 cores leave less headroom for streaming alongside games.
Why we like it
It suits a budget build now that can take an X3D chip later without changing boards. On L3 cache it trails the group at 32MB, while the Ryzen 9 9950X offers 64MB. On boost clock it trails the group at 5.4GHz, while the Core i9-14900K offers 6GHz.
Its 6 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 9950X and Ryzen 9 7900X; the Core Ultra 9 285K goes with an LGA1851 socket.
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 undercut the Ryzen 9 7900X and every other pick on price at the time of writing.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- 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.
- Platform cost
- We noted socket, memory type and whether a cooler is included, since they change the real price.
- 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 CPU for Gaming
Key buying criteria so you get the right fit the first time.
How much boost clock you need
Among these picks, boost clock runs from 5.4GHz on the Ryzen 5 9600X to 6GHz on the Core i9-14900K. Settle how much you need before comparing prices, since paying for more rarely helps if your use never reaches it.
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.
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.
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.
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.

Frequently Asked Questions
How do these processors compare on L3 cache?
The Ryzen 9 9950X leads at 64MB, ahead of the Ryzen 9 7900X at 64MB; the Ryzen 5 9600X sits at the other end with 32MB.
Which is the cheapest pick in this guide?
The Ryzen 5 9600X. It undercut the Ryzen 9 7900X when we checked, while the Core Ultra 9 285K cost the most of the group.
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 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.
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
Our first pick is the Core i9-14900K, chosen for the highest boost clock here (6GHz). Look at the Ryzen 9 9950X for AMD's recommendation of a liquid cooler, the Core Ultra 9 285K for the top of this price range, adding 8 performance and 16 efficient cores and the Ryzen 9 7900X for the Zen 4 architecture if those matter more to you.
At 4K the graphics card limits frame rates more than the CPU.
