Best LGA1851 Flagship1 of 6
Intel Core Ultra 9 285K on Amazon (opens in a new tab)
The Core Ultra 9 285K is Intel's twenty-four-core LGA1851 flagship.
Best for
- Gaming plus heavy creative work.
Skip if
- Skip it if this is a deal-breaker for you: no cooler in the box.
Why we like it
It targets heavy creative work more than frame rates alone. It matches the Core i9-14900K on L3 cache (36MB). Its 5.7GHz boost clock ranks second of 6 here, behind the Core i9-14900K (6GHz) and ahead of the Core Ultra 7 265KF (5.5GHz).
On core count it ties with the Core i9-14900K at 24 cores. Like the Core Ultra 7 265K and Core Ultra 7 265KF, it has an LGA1851 socket, while the Core i7-14700KF uses an LGA1700 socket. It also offers 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. At our last price check it topped the group, with the Core i9-14900K 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.
- Game-relevant specs
- We compared L3 cache, boost clocks and core counts from AMD's and Intel's product pages.
- 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.
What to Look for in a High-End Intel Gaming CPUs
Key buying criteria so you get the right fit the first time.
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.
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.
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.
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.
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.
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
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 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.
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.
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.
Bottom Line
For a new build, the Core Ultra 7 265K gives the best value and the 285K the most cores. On an existing LGA1700 board, choose the i7-14700K or i9-14900K and update the BIOS first.
