CPUs.

I rebuild a desktop or workstation every couple of years and end up doing the same research each time. These are the chips I would actually pay for this quarter, sorted by what the build is for — not by what is fastest on a chart.

§ 02

Picks, in detail

One paragraph per tier — what it’s for, what to pair it with, what to walk away from.

Six cores, integrated graphics, no fans on the GPU side.

Boring, cheap, sips power, drives two 4K displays from the iGPU. For a family PC or a meeting-room box this is the right answer.

Pair with a B650 board, 32 GB DDR5‑5200, and a quiet case. Total system cost lands well under £400. The Radeon 740M iGPU handles 1080p video playback and light gaming without drama. If you later add a GPU, the AM5 platform keeps pace with Zen 5 IPC.

Cheapest chip that does not bottleneck a current-gen GPU.

Zen 5 at the low end. Fast single-thread, sensible thermals, pairs happily with a B650 board and DDR5‑6000. Pair with a 7800 XT or 5070.

At 65 W the 9600X runs cool enough for a 120mm tower air cooler. Six cores is fine for every game shipping in 2026; nothing at the £300 GPU range is bottlenecked by it. The 9600 (non-X) saves £20 if you find one.

The 3D V‑Cache chip that nothing else catches at 1080p / 1440p.

Genuinely the fastest gaming CPU on the market and will be for another year. Eight cores is fine — the cache is doing the work.

Wants a 240mm AIO; a good tower air cooler will also do. Pair with a B650E or X670E board and DDR5‑6000 CL30. The productivity delta vs. the 9700X is small — if you encode or render frequently, look at the 9900X instead. If gaming is 80 % of your usage, this is the only chip worth considering above £250.

Twelve cores for the days you also compile, render or transcode.

Strong at games, strong at threaded workloads, doesn’t need a 360mm AIO. The chip I’d put in my own desktop right now.

Twelve Zen 5 cores at 5.6 GHz boost. A 240mm AIO keeps it happy. This is the build for a developer who games: compile fast enough that the wait is never the bottleneck, and game at 1440p without apology. The 9950X only makes sense if you genuinely saturate 12 cores regularly.

Sixteen cores, X3D cache, the no‑compromises pick.

If you need both render performance and X3D gaming speed in one socket, this is what you buy. Otherwise the 9900X above is the better value.

170 W under full load; needs a quality 360mm AIO and a board with solid VRMs. An X670E is the right pairing. The 9950X3D beats the non-X3D in both gaming and the majority of production workloads. If budget is a constraint at all, buy the 9900X and spend the difference on more storage or a better GPU.

How I choose

The five factors that drive every pick on this page.

Socket longevity
AM5 has another generation of CPUs committed. LGA1851 may or may not. Lean AM5 unless you specifically need Intel acceleration.
Memory
DDR5‑6000 CL30 is the platform sweet spot on AMD. Faster kits don’t help; slower kits cost you frame time.
Cooling
A 65 W chip is happy on a tower air cooler. 120 W X3D parts want a 240mm AIO. 170 W X3D wants 360mm.
Platform price
Don’t pair a £700 CPU with a £120 board. Match VRMs to the part you bought.
Honest scoring
Gaming and multi‑thread numbers above are normalised to the 9800X3D and 9950X3D respectively. “100” means class‑leader; not a real percentage.
