Processors (CPUs) Buying Guide and FAQ
Your processor (CPU) sets the pace for gaming and everyday work. Below are straight answers to the questions we hear most when buying a CPU in the UK, covering AMD Ryzen and Intel Core, the AM5 and AM4 sockets, X3D chips for gaming, and how to match a processor to your motherboard.
Which CPU should I buy for gaming in 2026?
For pure gaming, AMD's Ryzen X3D chips are the ones to beat. The Ryzen 7 9800X3D and 7800X3D lead the pack, with the Ryzen 5 7600X3D a great-value option. If you also do heavy multitasking or content creation, a Ryzen 9 or an Intel Core Ultra 7 or 9 makes sense. Remember that at 1440p and 4K most games lean on the graphics card, so you rarely need the most expensive CPU on the shelf.
Is AMD or Intel better for gaming and work?
Both are strong. AMD Ryzen, and especially the X3D models, usually wins for frames per pound in games and runs on the long-lived AM5 platform. Intel Core Ultra (Arrow Lake) is competitive and can edge ahead in some productivity tasks. For a gaming-first build we usually point people at Ryzen X3D, while mixed work and play is a close call between a Ryzen 9 and a Core Ultra 9.
What is AMD X3D (3D V-Cache) and is it worth it?
X3D chips stack extra cache onto the CPU, which games love. That is why the Ryzen 7 9800X3D and 7800X3D top most gaming charts. If your build is mainly for gaming, an X3D chip is usually worth the small premium because it lifts minimum frame rates and feels smoother. In most gaming CPU hierarchies the X3D chips sit right at the top, and they are the pick if you want the best AMD CPU for gaming. For workloads that do not use the cache, a standard Ryzen or Core Ultra can be better value.
AM5 or AM4 socket, which should I choose?
AM5 is the current AMD platform. It uses Ryzen 7000 and 9000 chips with DDR5 memory and has a long upgrade path, so it is the better choice for a new build. AM4 is older but still excellent value: a Ryzen 5 5600 or a Ryzen 7 5700X3D on a cheap board and DDR4 makes a strong budget gaming PC. Pick the socket first, then the matching motherboard.
Do I need a Core i9 or Ryzen 9?
Usually not for gaming. A Ryzen 7 X3D or a Core Ultra 7 handles modern games beautifully. The Ryzen 9 and Core Ultra 9 chips, and AMD Threadripper, are aimed at heavy multitasking, video editing, 3D and streaming while you play. If that is not you, save the money and put it towards your graphics card or an SSD.
Do I need a new motherboard and cooler for my CPU?
Your CPU must match the motherboard socket (AM5, AM4 or the current Intel socket), so check this before you buy. Most CPUs also need a cooler: many Ryzen chips include one, but X3D and higher-end models run better with a separate air or liquid cooler. See our motherboards and CPU coolers to complete the build.
