What this tier is for
These machines run Core Ultra 9 processors on the LGA1851 platform, paired with an RTX 5080 or RTX 5090 and 32GB or 64GB of DDR5. Every one is badged for 4K. They are the top of what we build on Intel.
Worth being straight about who they suit. Core Ultra 9 is defined by its core count, and games do not use it. If the machine only ever plays games, a Core Ultra 7 with the same graphics card will play them to all intents identically, for a good deal less.
This tier earns its money when the machine does production work as well: video rendering, encoding, compiling, virtual machines, or streaming at a quality that leans on the processor rather than the card. That is where cores are the limit and where the gap opens up.
Why Intel is different from AMD here
AMD's top tier includes X3D chips, which carry a much larger cache and raise frame rates in games specifically, so you can buy a flagship processor that is also the right choice for gaming. Intel has no direct equivalent.
That makes the decision cleaner rather than worse. At this tier on Intel you are buying cores, and you should buy them because you have work that uses them. Our guide comparing Core Ultra and Core i covers the differences between the two Intel lines.
Cooling and power
A processor and graphics card at this level produce a lot of heat, and a system that cannot move it will quietly slow itself down to stay safe. Cooling here is specified alongside the components rather than after them.
Power is the part people underestimate, because current cards draw sharp transient spikes well above their rated figure. Our guide on what power supply wattage you need covers the headroom these actually want if you are speccing a build of your own in the PC configurator.
Every machine is hand built and tested here in the UK with a 3 year warranty as standard.
Core Ultra 9 gaming PC FAQs
Do I need a Core Ultra 9 for gaming?
If the machine only plays games, no. Games do not use 24 cores, and a Core Ultra 7 with the same graphics card will play them to all intents identically for considerably less. This tier is for machines that also do production work.
What does the core count actually buy?
Anything that splits across many cores at once: video rendering, encoding, compiling, running virtual machines, and streaming at a quality that leans on the processor rather than the card. It also means you can do that work while a game is running without either suffering.
Is there an Intel equivalent of AMD's X3D?
No. AMD's X3D chips stack extra cache onto the processor to raise frame rates in games specifically, which gives you a top tier chip that is also the best choice for gaming. Intel has no direct counterpart, so at this tier on Intel the core count is what you are buying.
Will the processor hold back an RTX 5090?
No. At 4K the graphics card does nearly all the work and a Core Ultra 9 has headroom well beyond what these cards ask of it. The processor matters more at 1080p and at very high refresh rates than at the resolution these are built for.
What power supply do these need?
More than most people expect, because current cards draw sharp transient spikes well above their rated figure. These are specified with that headroom built in. Our guide on what power supply wattage you need sets out the numbers if you are speccing your own.

If the machine is for gaming alone, Core Ultra 7 gaming PCs cover the same ground for less. Otherwise see the whole Intel range, compare against our AMD gaming PCs, or browse our high end gaming PCs.
