AMD Ryzen 7 5800 XT Processor (8 Cores/16 Threads, 105W DTP, AM4 Socket, 36MB Cache, Up to 4.8 GHz max boost frequency, Wraith Prism Cooler)
The Ryzen 5 3600 has been a staple recommendation for years, and honestly, it still earns its place. Six cores, 12 threads, a 35MB cache, and a 65W TDP make it a genuinely balanced chip for everyday computing, light gaming, and productivity work. It's Zen 2 architecture, so it's not the newest thing on the block, but it's mature, well-supported, and the AM4 ecosystem around it is incredibly affordable.
For the best AMD CPUs under £300 conversation, the 3600 sits in a sweet spot. You're getting a chip that handles 1080p gaming without complaint, breezes through web browsing and office tasks, and comes with the Wraith Stealth cooler so you don't need to spend extra on cooling. The 4.1GHz max boost is modest by today's standards, but paired with a decent GPU it still holds up in most titles.
Real owner feedback is overwhelmingly positive for the price. Most buyers use it for mid-range gaming builds and report it runs cool and quiet under the Wraith Stealth. The main limitation is that it lacks integrated graphics, so you'll need a dedicated GPU. And if you're doing heavy video editing or 3D rendering, you'll feel the Zen 2 ceiling fairly quickly. But for general use? Sorted.
It's worth pointing out that the 5600X (below) often comes in cheaper and outperforms it. So if the pricing is close when you're shopping, go for the 5600X. But the 3600 remains a dependable, proven choice and earns its top spot as our overall pick for this roundup.
Pros
Proven, stable AM4 platform with wide motherboard support
Includes Wraith Stealth cooler, no extra spend needed
Here's the thing: the Ryzen 5 5600X might be the best value gaming CPU AMD has ever made. It launched at a premium but has since dropped to a price that makes it almost unfair competition for everything around it. Zen 3 architecture, 4.6GHz boost, 35MB cache, and 65W TDP. It's a proper chip at a budget price.
In gaming, the 5600X consistently trades blows with chips costing significantly more. Single-core performance is strong, which is what matters most for frame rates. Owners report smooth 1080p and 1440p gaming across a wide range of titles, and the Wraith Stealth cooler keeps it comfortable under load. For the best AMD CPUs under £300, this is the one you'd pick if gaming is your priority.
Productivity is solid too. Six cores and 12 threads handle video editing, streaming, and multitasking without drama. It's not going to replace an eight-core chip for heavy rendering, but for most people it's more than enough. The AM4 platform means cheap motherboard options and DDR4 RAM, keeping your total build cost down.
The only reason it's not our overall number one is that the 3600 has a longer track record and slightly broader availability. But performance-wise, the 5600X wins. If you can get it at or below the 3600's price, buy it without hesitation.
Pros
Zen 3 architecture delivers excellent single-core performance
Outstanding gaming performance for the price
Wraith Stealth cooler included
AM4 means affordable motherboard and RAM options
Cons
No integrated graphics
AM4 is a mature platform with limited future upgrade path
The Ryzen 5 4500 is a reasonable starter chip, but you need to go in with eyes open. Six cores and 12 threads sounds great on paper, and the Wraith Stealth cooler is a nice inclusion. But that 11MB cache is noticeably smaller than the 3600's 35MB, and it uses Zen 2 architecture just like the 3600, which makes the pricing comparison awkward.
For beginners building their first PC, the 4500 is approachable. It's not intimidating, it runs cool, and it handles everyday tasks without any fuss. Light gaming, web browsing, streaming, office work. All fine. But anyone stepping up from a very old system will notice the performance gap compared to Zen 3 options.
The honest take: at its current price, it's hard to recommend over the 5600X unless there's a meaningful price difference. The cache limitation does show up in some games and workloads. That said, for a first build where budget is genuinely tight and you just need something that works, it does the job without drama.
Pros
Six cores and 12 threads for everyday multitasking
Wraith Stealth cooler included
Low 65W TDP, easy to cool
Good for first-time builders on AM4
Cons
Only 11MB cache, noticeably less than the 3600 or 5600X
The Ryzen 5 7600 is where things get interesting if you're thinking about the future. It's an AM5 chip, which means DDR5 memory and a platform that AMD has committed to supporting for years to come. Six cores, 12 threads, 5.1GHz boost, 38MB cache, and integrated Radeon graphics. That's a strong spec sheet for the money.
The integrated graphics are basic but genuinely useful. You can run a display without a dedicated GPU, which is handy during a build or if your graphics card fails. For the best AMD CPUs under £300 with AM5 longevity, the 7600 makes a compelling case. Gaming performance is strong, and the higher boost clock over the 5600X shows up in CPU-limited scenarios.
The catch is the platform cost. AM5 motherboards and DDR5 RAM cost more than their AM4 equivalents. So while the CPU itself is reasonably priced, your total build spend will be higher. If you're planning to upgrade the CPU down the line though, AM5 gives you somewhere to go. The Wraith Stealth cooler is included, which helps offset costs a little.
Pros
AM5 platform with long-term upgrade potential
Integrated Radeon graphics included
5.1GHz boost clock is strong for the price
38MB cache, more than the AM4 Zen 3 chips
Wraith Stealth cooler bundled
Cons
AM5 motherboards and DDR5 RAM add to total build cost
Zen 5 at this price is genuinely surprising. The Ryzen 5 9600X brings AMD's latest architecture to the sub-£200 bracket, and the performance uplift over Zen 4 is real, particularly in single-threaded tasks that matter for gaming. Five point four GHz boost, 38MB cache, integrated graphics. It's a proper modern chip.
For anyone hunting the best AMD CPUs under £300 who wants the newest technology without going near the top of the budget, the 9600X is a serious contender. Real-world gaming performance is excellent, and the efficiency improvements in Zen 5 mean it runs cooler and more quietly than you might expect for a high-boost chip.
The big caveat: no cooler in the box. You'll need to budget for one separately, which adds to the total cost. The AMD Wraith Prism Cooler (listed separately in this roundup) is one option, or any decent 120mm AIO or tower cooler will do the job. Factor that in before comparing prices with the Wraith Stealth-equipped chips.
Pros
Zen 5 architecture, AMD's latest and most efficient
The Ryzen 5 5600GT fills a specific gap: AM4 with integrated graphics. If you're on an existing AM4 board and want to build or upgrade without buying a GPU straight away, this is your chip. Zen 3 architecture, 4.6GHz boost, and Radeon integrated graphics make it a genuinely useful all-in-one package.
Performance is solid for everyday tasks and light gaming on the integrated graphics. Don't expect miracles from the iGPU in demanding titles, but for older games, esports titles, or just getting a system up and running while you wait for GPU prices to drop, it works. The 19MB cache sits between the 3600 and 5600X, which is fine for most workloads.
It's priced a bit higher than the 5600X, which is the trade-off for getting integrated graphics on AM4. If you already have a GPU or plan to buy one soon, the 5600X is better value. But if you need that iGPU fallback, the 5600GT earns its price premium.
Pros
Integrated Radeon graphics on AM4, a rare combination
Zen 3 architecture with 4.6GHz boost
Wraith Stealth cooler included
Good for builds without an immediate GPU purchase
Cons
Costs more than the 5600X for less cache
Integrated graphics are basic, not for serious gaming
Eight Zen 5 cores at 65W. That's the headline, and it's a good one. The Ryzen 7 9700X is the most capable chip in this roundup for productivity workloads, offering 16 threads, 40MB cache, and a 5.5GHz boost clock in a package that sips power compared to its predecessors. For video editing, 3D work, streaming while gaming, or any heavily threaded task, this is where you want to be.
Gaming performance is also excellent. The high boost clock and Zen 5 IPC improvements mean it handles CPU-intensive titles with ease. It's not a huge leap over the 9600X in pure gaming, but the extra cores make a real difference if you're doing anything else at the same time.
The 65W TDP is genuinely impressive for an eight-core chip. It runs cool enough that a mid-range tower cooler handles it comfortably, though you will need to buy one since AMD doesn't include a cooler. That's the main gripe. At around £251, it's near the top of our budget, but the performance justifies it. This is the chip we'd pick if productivity matters as much as gaming.
Pros
Eight Zen 5 cores at an efficient 65W TDP
5.5GHz boost, excellent for gaming and productivity
The Ryzen 5 8600G is the chip to pick if you genuinely don't want a dedicated GPU, at least not yet. It packs the best integrated graphics in this entire roundup, with Radeon 760M graphics that can actually handle some light gaming at 1080p on lower settings. That's a meaningful step above the basic iGPUs in the 7600 or 9600X.
The Ryzen AI features are a bonus for anyone interested in AI-accelerated workflows, though most home users won't notice them day to day. Six cores, 12 threads, and a 5.0GHz boost make it a capable everyday chip. The Wraith Stealth cooler is included, which is appreciated at this price point.
It sits on AM5, so you get the platform longevity benefit. The 22MB cache is decent but not class-leading. For the best AMD CPUs under £300 without a GPU, this is the one. Just know that if you add a dedicated graphics card later, the iGPU advantage disappears and the 9600X or 7600 might have been better picks for pure CPU performance.
Pros
Best integrated graphics in this roundup, Radeon 760M
Ryzen AI features for AI-accelerated tasks
AM5 platform with upgrade headroom
Wraith Stealth cooler included
Cons
iGPU advantage disappears once you add a dedicated GPU
22MB cache is lower than AM5 competitors
Slightly older Zen 4 architecture vs the 9600X's Zen 5
The Ryzen 3 3200G is the cheapest chip in this roundup by a significant margin, and it shows in the specs. Four cores, four threads (no hyperthreading), 6MB cache, and a 4.0GHz boost. It's not going to set any benchmarks on fire. But it does include Radeon Vega 8 integrated graphics, which means you can build a functional PC without spending anything on a GPU.
For basic use cases, it's fine. Web browsing, office applications, video streaming, light photo editing. It handles all of that without complaint. The Wraith Stealth cooler keeps it cool and quiet. And the AM4 platform means cheap motherboard options.
The honest limitation: four threads in 2026 is tight. Modern browsers, background apps, and even some office software can push it. Gaming is limited to older or less demanding titles on the Vega 8 iGPU. It's a chip for very specific situations, like a basic home PC, a media centre, or a temporary build while you save for something better. Don't buy it expecting gaming performance. Do buy it if you need the cheapest possible functional PC.
Pros
Very affordable, the cheapest CPU in this roundup
Radeon Vega 8 iGPU, no dedicated GPU needed
Wraith Stealth cooler included
Low power consumption, good for small form factor builds
Eight Zen 3 cores on AM4, with the premium Wraith Prism cooler included. The Ryzen 7 5800 XT is the chip for AM4 users who want more cores without jumping to AM5. Sixteen threads, 36MB cache, and a 4.8GHz boost make it a capable productivity and gaming chip that fits within the best AMD CPUs under £300 budget.
The 105W TDP is higher than most chips in this list, which is why AMD includes the Wraith Prism rather than the Stealth. It's a proper cooler with RGB lighting and enough thermal headroom to keep the 5800 XT comfortable under sustained load. Owners report it runs warm but stable, and the cooler handles it without needing aftermarket solutions for most use cases.
Gaming performance is strong, and the extra cores over the 5600X make a real difference in streaming, content creation, and heavily threaded workloads. The trade-off is that AM4 has a limited upgrade path, and the 9700X on AM5 offers eight Zen 5 cores at a similar price with better efficiency. But if you're already on AM4 and want a meaningful upgrade, the 5800 XT is a proper step up.
Pros
Eight Zen 3 cores on AM4, great for existing AM4 builds
Wraith Prism cooler included, no extra spend needed
36MB cache, solid for gaming and productivity
Strong multithreaded performance
Cons
105W TDP, higher power draw than most in this list
No integrated graphics
AM4 upgrade path is limited compared to AM5
The 9700X offers better efficiency at a similar price
This one's a bit different. The AMD Wraith Prism Cooler isn't a CPU, it's the standalone version of the premium cooler that ships with the Ryzen 7 5800 XT. We've included it because several chips in this roundup, specifically the Ryzen 5 9600X and Ryzen 7 9700X, ship without any cooler at all. And you need something to keep them running.
The Wraith Prism is a genuinely good stock-class cooler. It handles up to 105W TDP chips comfortably, has RGB lighting that connects to your motherboard headers, and is compatible with AM4 and AM3+ sockets. For the best AMD CPUs under £300 that arrive without cooling, this is a practical and affordable solution that doesn't require you to research aftermarket options.
It won't replace a high-end tower cooler or AIO for overclocking or extreme workloads, but for the 9600X or 9700X running at stock settings, it's more than adequate. At around £39, it's a sensible add-on purchase rather than a headline product. But it earns its place in this roundup as the best budget cooling solution for cooler-less AMD chips.
Pros
Affordable standalone cooler for chips without bundled cooling
Handles up to 105W TDP comfortably
RGB lighting with motherboard header support
Compatible with AM4 and AM3+ sockets
Cons
Not suitable for AM5 without an adapter
Not a replacement for high-end aftermarket cooling
If you've already got an Intel 12th, 13th, or 14th gen CPU sat in your build but you're frustrated with uneven contact between the chip and your cooler, the Thermalright Contact Frame V2 is a genuinely clever fix. It's a retrofit bracket that sits between your processor and cooler, ensuring perfectly flat, uniform pressure across the entire IHS (Integrated Heat Spreader). No more hot spots, no more thermal paste lottery.
The anti-bending buckle design is the real star here. Intel's LGA 1700 socket can suffer from slight warping under cooler pressure, which tanks thermal performance without you realising it. This frame counteracts that, and users report temperature drops of 5 to 10 degrees Celsius depending on their cooler and mounting method. For the price (just £12.90), that's exceptional value if you're already running one of these chips and want to squeeze out better thermals without replacing your cooler.
Installation is straightforward enough if you're comfortable removing your cooler. You'll need to unmount everything, fit the frame, remount the cooler, and reapply thermal paste. It's not a five-minute job, but it's not rocket science either. The frame is precision-machined aluminium, so it feels solid and won't warp itself. One caveat: it only works with LGA 1700, so if you're on AM4 or older Intel sockets, this won't help you.
The rating of 9 reflects genuine owner satisfaction. Most people who buy this are already aware of the LGA 1700 contact issue and see immediate results. The main downside is that it's a niche product. If your thermals are already fine, you won't notice much difference. And if you're using a high-end cooler with excellent mounting pressure, the gains might be marginal. But for budget and mid-range cooler users, this is a no-brainer upgrade.
Pros
Measurable temperature improvements (5 to 10°C drop reported)
Extremely affordable retrofit solution
Precision aluminium construction, feels premium
Works with any LGA 1700 cooler, no compatibility headaches
Anti-bending design addresses a real Intel socket weakness
Cons
Only compatible with LGA 1700 (Intel 12th/13th/14th gen)
Requires cooler remount and thermal paste reapplication
Gains are minimal if you already have excellent cooler contact
Buying Guide: What to Look For in the Best AMD CPUs Under £300
AM4 vs AM5: Which platform should you choose?
This is the first decision to make. AM4 is AMD's older platform, using DDR4 memory and a wide range of affordable motherboards. It's a mature ecosystem with great value, but AMD has confirmed AM5 as the future. If you're building fresh and want upgrade headroom, AM5 is worth the extra platform cost. If you're upgrading an existing AM4 system, stick with AM4 and save the money.
Core count and threads
For gaming, six cores and 12 threads is the sweet spot right now. Most games don't use more than six cores efficiently, so the jump to eight cores mainly benefits productivity workloads like video editing, 3D rendering, and streaming. Don't pay for cores you won't use, but don't go below six either.
Boost clock speed
The boost clock is the maximum speed a single core can reach under load. Higher is better for gaming, since most games rely on fast single-core performance. The chips in this roundup range from 4.0GHz on the 3200G to 5.6GHz on the 9900X. Anything above 4.6GHz is solid for modern gaming.
Cache size
Cache is often overlooked but matters more than people realise, especially for gaming. The Ryzen 5 3600 and 5600X both have 35MB of cache, which helps with frame consistency. The 4500's 11MB is noticeably lower. Bigger cache generally means smoother performance in games and workloads that repeatedly access the same data.
TDP and cooling
TDP (thermal design power) tells you how much heat the chip produces and what cooler you need. Most chips here are 65W, which the bundled Wraith Stealth handles fine. The 5800 XT runs at 105W and comes with the Wraith Prism. The 9900X is 120W and ships without a cooler, so budget for a proper aftermarket solution.
Integrated graphics
Not all AMD chips have integrated graphics. If you're building without a dedicated GPU, or want a fallback option, check the spec carefully. The 8600G, 5600GT, 7600, 9600X, 9900X, and 3200G all include iGPUs. The 3600, 5600X, 4500, 9700X, and 5800 XT do not.
Common mistakes to avoid
Don't buy an AM5 CPU without budgeting for an AM5 motherboard and DDR5 RAM. Don't assume a higher model number means better value. And don't overlook the cooler situation: chips without bundled cooling add real cost to your build.
How We Tested
We assessed each chip based on published specifications, architecture generation, real-world owner feedback from verified Amazon UK buyers, and independent benchmarks from sources including AMD's official processor pages and Tom's Hardware CPU reviews. Pricing was assessed at time of writing and reflects typical UK retail availability. We weighted value for money heavily, alongside platform longevity, bundled accessories, and suitability for the most common use cases in this price bracket.
Best Overall
AMD Ryzen 5 3600
Proven AM4 performance, 6 cores, 12 threads, 35MB cache, and a bundled Wraith Stealth cooler. The reliable all-rounder for budget builds.
The best AMD CPUs under £300 cover a genuinely impressive range of performance and use cases in 2026. For most people, the Ryzen 5 5600X is the smartest buy: Zen 3 performance, a bundled cooler, and AM4 affordability make it the easiest recommendation we can make. If you want AM5 and future-proofing, the Ryzen 5 7600 or Ryzen 5 9600X are the picks, with the 9600X edging ahead on raw performance thanks to Zen 5. For productivity-heavy workloads, the Ryzen 7 9700X is exceptional value at eight Zen 5 cores and just 65W. And if you need the absolute cheapest entry point with integrated graphics, the Ryzen 3 3200G does the job without fuss. Whatever your budget and use case, there's a genuinely good AMD chip in this list for you.
Frequently Asked Questions
AM4 is AMD's older socket standard, nearing end-of-life with no upcoming processors planned. AM5 represents the current and future standard, supporting multiple processor generations through 2027+. For new builds, AM5 provides substantially better long-term upgrade viability, though AM4 motherboards currently offer lower pricing due to older inventory.
Yes, but with limitations. Integrated Radeon graphics handle 1080p gaming at medium-to-high settings, achieving 40 to 60 fps in modern titles. 1440p gaming becomes impractical; you'll need medium settings and potentially 30 to 45 fps. For demanding gaming, discrete graphics remain essential.
Most budget processors carry 65W TDP ratings, compatible with basic tower coolers or modest all-in-one liquid solutions. Exceptions include the 5800 XT and 7500X3D at 105W, requiring quality tower coolers and adequate case airflow. Budget 65W chips can utilise fanless or passive cooling in some applications.
The Ryzen 7 9700X and 5800 XT both offer eight cores for simultaneous gaming and encoding. The 9700X provides superior long-term value through AM5 socket support and lower TDP, though the 5800 XT delivers identical encoding performance if you prioritise immediate availability on AM4 platforms.
AM5 investment makes sense for anyone building now, despite higher motherboard costs, as you'll maintain upgrade viability through 2027. AM4 only makes sense if purchasing used boards or already owning compatible platforms. New AM4 builders lock themselves into a dead platform with limited future options.
