Best AMD CPUs Under £300

1. AMD Ryzen 5 3600 Processor (6 Cores/12Threads, 65W DTP, AM4 Socket, 35 MB Cache, up to 4.1 GHz Max Boost frequency, Wraith stealth cooler)

Price: £140.03 | Rating: ★★★★½ (4.8)

The Ryzen 5 3600 has been around long enough to feel like a classic. And honestly? It still earns its place in a best AMD CPUs under £300 roundup in 2026. Six cores, twelve threads, a 65W TDP, and 35MB of combined cache. It is not the fastest chip here by any stretch, but it is one of the most proven.

For everyday computing, light gaming, and general productivity, the 3600 handles everything without complaint. The 4.1GHz max boost is modest compared to newer Zen 3 and Zen 5 chips, but real-world performance in tasks like web browsing, office applications, and 1080p gaming is still perfectly acceptable. Owners consistently praise its stability and the fact that it just works, often for years without issue.

The AM4 platform is the other big draw here. Motherboards are cheap and plentiful. You can pick up a decent B450 or B550 board for very little, which keeps total build costs down. That matters when you are working within a tight budget. The included Wraith Stealth cooler is adequate for stock operation, though anyone planning to push the chip harder will want something better.

The honest limitation is that the 3600 is now a few generations behind. It will not match the Ryzen 5 5600X in gaming or the AM5 chips in future-proofing. But as a budget AMD CPU that just gets the job done, it remains a solid pick, especially if you find it at a good price.

2. AMD Ryzen 5 5600X Processor (6 Cores/12Threads, 65W TDP, AM4 Socket, 35MB Cache, up to 4.6 GHz Max Boost, Wraith Stealth Cooler)

Price: £145.99 | Rating: ★★★★½ (4.8)

If the Ryzen 5 3600 is the reliable workhorse, the 5600X is the thoroughbred. Same six cores and twelve threads, same 65W TDP, same AM4 socket. But the Zen 3 architecture underneath is a proper step forward. The 4.6GHz max boost and improved IPC (instructions per clock) translate into noticeably snappier gaming performance and faster single-threaded work.

For gaming specifically, the 5600X was the benchmark chip for AM4 for a long time, and it still holds up well. Games that rely on fast single-core performance respond well to the higher boost clocks. Content creators doing light video editing or streaming alongside gaming will appreciate the headroom the Zen 3 architecture provides.

Build quality and manufacturing consistency are excellent. AMD's Zen 3 chips have an outstanding reputation for reliability, and owner reviews back this up. The 5600X runs cool and quiet on the included Wraith Stealth cooler under normal loads. It is the kind of chip you install and forget about for years.

The price is slightly higher than the 3600, which is fair given the performance gap. The AM4 dead-end concern applies here too, but if you are not planning to upgrade the CPU again for three or four years, that is not really a problem in practice.

3. AMD Ryzen 5 8400F processor (6 Core/12 threads, 65W TDP, AM5 Socket, 22MB Cache, up to 4.7GHz max boost frequency, with wraith stealth cooler)

Price: £127.99 | Rating: ★★★★½ (4.6)

Here is the thing about the Ryzen 5 8400F: it is the most exciting budget chip in this entire roundup. AM5 platform, modern Zen 4 architecture, a 4.7GHz boost clock, and it comes with the Wraith Stealth cooler. The catch? No integrated graphics. You need a dedicated GPU. But if you already have one, or you are buying a GPU anyway, this is outstanding value.

The 8400F sits on the AM5 platform, which means DDR5 memory, PCIe 5.0 support, and a clear upgrade path to future AMD processors. That is a big deal for a chip at this price point. You are not just buying a CPU, you are buying into a platform that will still be relevant in several years.

Performance is genuinely impressive for the money. The Zen 4 architecture handles gaming, productivity, and multitasking with ease. It is faster than the Ryzen 5 3600 and competitive with the 5600X, all while sitting on a more modern platform. Owner feedback highlights how well it performs in gaming rigs paired with mid-range GPUs.

The no-iGPU limitation is real. If your GPU fails, you have no display output. For most builders this is a non-issue, but it is worth knowing upfront.

4. AMD Ryzensets 3 3200G processor (Radeon Vega 8 integrated GPU, 4 cores/4 threads, 65W TDP, AM4 socket, 6MB Cache, up to 4.0 Ghz max boost frequency, wraith stealth cooler)

Price: £60.51 | Rating: ★★★★½ (4.7)

Four cores, four threads, and integrated Radeon Vega 8 graphics. The Ryzen 3 3200G is not going to win any benchmarks in 2026. But for someone building their very first PC on a shoestring, it is a proper decent starting point. You do not need a dedicated GPU to get a display output, which saves money upfront and removes one potential point of failure for a first-time builder.

The Vega 8 integrated graphics can handle light gaming at low settings, 1080p video playback, and general desktop use without issue. Think older titles, esports games at reduced quality, and everyday productivity. It is not a gaming chip, but it is a capable all-rounder for someone who just needs a working PC.

The AM4 platform keeps board costs low, and the included Wraith Stealth cooler means you do not need to budget for cooling either. Total build costs can be kept very manageable. The 6MB cache is tight and the four-thread limitation will show in heavier workloads, but for a beginner who plans to add a GPU later, this is a sensible foundation.

Be honest with yourself about what you need it for. If you are gaming seriously or doing any creative work, step up to at least the Ryzen 5 3600. But as a first build chip? The 3200G earns its place.

5. AMD Ryzen 5 7600 Processor (radeon graphics integrated, 6 cores/12 threads, 65W TDP, AM5 Socket, 38MB cache, up to 5.1 GHz max boost, Wraith Stealth Cooler)

Price: £169.99 | Rating: No rating

The Ryzen 5 7600 is the chip that makes AM5 genuinely accessible. It comes in under the Ryzen 5 9600X in price, includes the Wraith Stealth cooler, and brings integrated Radeon graphics as a safety net. The 5.1GHz max boost is fast, the 38MB cache is generous, and the Zen 4 architecture is a big step up from anything on AM4.

For gaming, the 7600 is excellent. It keeps up with more expensive chips in most titles because gaming performance is largely single-core dependent, and the 7600's single-core speed is very strong. Paired with a mid-range GPU, it will not bottleneck you in any mainstream game.

The integrated Radeon graphics are not powerful enough for serious gaming, but they are there as a fallback if your GPU has a problem. That is genuinely useful. The 65W TDP also means it runs cool and quiet, which matters for smaller builds or anyone who wants a quiet system.

The main consideration is the AM5 platform cost. You will need a compatible motherboard and DDR5 memory. But once that investment is made, you have a platform with a long upgrade path ahead of it. For anyone building a new gaming PC today, the 7600 is a very strong choice in the best AMD CPUs under £300 category.

6. AMD Ryzen 5 9600X Processor (radeon graphics included, 6 Cores/12 Threads, 65W TDP, Socket AM5, Cache 38MB, up to 5.4 GHz max boost Frequency, no cooler)

Price: £168.99 | Rating: ★★★★½ (4.8)

Zen 5. That is the headline here. The Ryzen 5 9600X is AMD's latest six-core chip, and the architectural improvements over Zen 4 are real. The 5.4GHz max boost is the highest of any six-core chip in this roundup, and the IPC gains mean it actually uses those clocks more effectively than older chips could.

For gaming, this is the best six-core option in the best AMD CPUs under £300 lineup. Single-core performance is outstanding. It handles CPU-heavy games, streaming, and background tasks simultaneously without breaking a sweat. The 38MB cache helps with latency-sensitive workloads too.

The integrated Radeon graphics are a nice inclusion, giving you a display output without a dedicated GPU. They are not gaming-capable in any meaningful sense, but they are there. The 65W TDP is impressively efficient for a chip this fast.

The big catch is the missing cooler. AMD does not include one in the box, so budget for an aftermarket cooler. Something like a basic tower cooler will do fine given the 65W TDP, but it is an extra cost to factor in. At the current price, the 9600X represents excellent value for a gaming-focused build on AM5.

7. AMD Ryzen 5 5600GT processor (integrated Radeon Graphics, 6 cores/12 threads, 65W DTP, AM4 Socket, Cache 19MB, up to 4,6Ghz max boost, with wraith stealth cooler)

Price: £142.47 | Rating: ★★★★½ (4.8)

Think of the 5600GT as the 5600X with integrated graphics bolted on. Same six cores, same twelve threads, same 4.6GHz max boost on the Zen 3 architecture. But this one has Radeon graphics built in, which makes it a brilliant option for anyone building a PC where a dedicated GPU is coming later, or for a compact build where space or power budget is tight.

The integrated graphics are more capable than the Vega 8 in the Ryzen 3 3200G, handling light gaming and media tasks comfortably. It is not a replacement for a proper GPU, but it is a proper stopgap. The 19MB cache is lower than the 5600X's 35MB, which does show in some workloads, but for most everyday tasks you will not notice.

On AM4, you get cheap board options and a mature ecosystem. The Wraith Stealth cooler is included. For a budget AMD CPU build where flexibility matters, the 5600GT is a smart choice that does not force you to buy a GPU on day one.

8. AMD Ryzensets 5 8600G processor (integrated Radeon Graphics,Ryzensets AI, 6 cores/12 threads, 65W TDP, AM5 Socket, Cache 22MB, up to 5,0Ghz max booth, with wraith stealth cooler)

Price: £147.00 | Rating: ★★★★½ (4.8)

The Ryzen 5 8600G is the chip for anyone who wants to skip a dedicated GPU entirely, at least for now, but still wants to be on the modern AM5 platform. The integrated Radeon 760M graphics are a significant step up from anything on AM4, capable of handling light gaming at 1080p in older and less demanding titles.

Six cores, twelve threads, a 5.0GHz boost, and the Wraith Stealth cooler in the box. The 22MB cache is adequate. The AI processing features (Ryzen AI) are a bonus for anyone interested in local AI workloads, though most users will not use them day to day.

For a GPU-free build on AM5, this is the best option in the best AMD CPUs under £300 lineup. It is more capable than the 5600GT's integrated graphics and sits on a platform with a real future. The trade-off is that AM5 boards and DDR5 memory cost more than AM4 equivalents, so the total build cost is higher even if the CPU price is reasonable.

9. AMD Ryzen 7 9700X Processor (8 Cores/16 Threads) 65W DTP, AM5 socket, 40MB Cache, Up to 5.5 GHz max boost frequency, no cooler

Price: £242.76 | Rating: ★★★★½ (4.8)

Eight Zen 5 cores, sixteen threads, 5.5GHz boost, and 40MB of cache for under £250. The Ryzen 7 9700X is genuinely impressive value at this price point. It is the best multi-threaded chip in this roundup by a clear margin, and it does it all at a 65W TDP, which is remarkable for an eight-core processor.

For content creators, streamers, video editors, and anyone running demanding multi-threaded workloads alongside gaming, the 9700X is the chip to get in the best AMD CPUs under £300 category. The extra cores over the six-core chips make a real difference in rendering, compilation, and anything that scales with thread count.

Gaming performance is also excellent. The 5.5GHz boost and Zen 5 IPC improvements mean it is competitive with the 9600X in single-threaded gaming tasks while offering significantly more headroom for everything else. It is a proper all-rounder.

No cooler in the box is the main annoyance. Budget for an aftermarket unit. And the AM5 platform costs apply here too. But for the performance on offer, the 9700X is one of the best value chips AMD has ever made at this price.

10. AMD Ryzensets 9 9900X Processor (radeon graphics integrated, 12 Cores/24 Threads, 120W DTP, AM5 Socket, 76MB Cache, Up to 5.6 GHz max boost frequency, No Cooler)

Price: £299.97 | Rating: ★★★★½ (4.8)

Twelve cores, twenty-four threads, 76MB of cache, and a 5.6GHz boost. The Ryzen 9 9900X is the most powerful chip in this roundup and sits right at the top of the sub-£300 budget. It is overkill for gaming. Full stop. But for content creation, 3D rendering, video encoding, and any workload that genuinely scales with core count, it is a different story.

The 120W TDP is the big caveat. This chip runs hot and needs a proper aftermarket cooler, which is not included. Budget for a decent 240mm AIO or a high-end tower cooler. Without adequate cooling, you will not see the full boost clocks.

For the right user, though, the 9900X at this price is genuinely exciting. Twelve Zen 5 cores with 76MB of cache and integrated Radeon graphics. It is a serious workstation chip that happens to fit within the best AMD CPUs under £300 budget. Just make sure your use case actually needs this many cores before spending the money.

11. AMD Ryzen 5 4500 Processor (6 Cores/12 Threads, 65W DTP, AM4 Socket, 11 MB Cache, Up to 4.1 GHz Max Boost, wraith stealth cooler)

Price: £190.99 | Rating: ★★★★½ (4.7)

The Ryzen 5 4500 sits in an awkward spot. Six cores, twelve threads, 4.1GHz boost, and the Wraith Stealth cooler. On paper it sounds fine. But the 11MB cache is notably lower than the Ryzen 5 3600's 35MB, and the Zen 2 architecture (same generation as the 3600) does not justify the higher price. It is hard to recommend over the 3600 at current pricing.

For a best AMD CPUs under £300 roundup, the 4500 is the chip you pick when the 3600 and 5600X are both out of stock. It will handle everyday tasks and light gaming without complaint, but it is not the best value option at its current price point. The low cache particularly hurts in gaming workloads where the 3600's larger cache gives it a real-world edge.
