Finding the best AMD CPUs under £100 in 2026 is genuinely tricky. The sub-£100 bracket has become surprisingly competitive, and AMD's AM4 platform means older chips still hold real value. This comparison puts three products head to head: the AMD Ryzen 3 3200G with its built-in Vega 8 graphics, the AMD Ryzen 5 4500 with six cores and twelve threads, and the AMD Wraith Prism Cooler as a standalone cooling upgrade. Yes, one of these is a cooler, not a CPU. That matters, and we'll explain why it ended up in this roundup and whether it actually makes sense to buy. If you're building or upgrading a budget PC on AM4, this is the comparison you need. Every pound counts here.
CPU Performance: Which Processor Wins on Raw Speed?
Winner: AMD Ryzen 5 4500
Here's the thing: the performance gap between these two CPUs is bigger than the price gap suggests. The 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) runs on Zen 2 architecture with 6 cores and 12 threads. The 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) uses the older Zen+ architecture with just 4 cores and no simultaneous multithreading.
In Cinebench R23 multi-core testing, the Ryzen 5 4500 scores around 8,500 to 9,000 points. The Ryzen 3 3200G manages roughly 4,200 to 4,500. That's approximately double the multi-threaded throughput. Single-core scores are closer, around 1,050 for the 4500 versus 950 for the 3200G, but the multi-core difference is what you'll actually feel day to day.
Say you're compiling code, rendering a short video clip, or running a browser with 20 tabs open alongside a Zoom call. The 4500's 12 threads mean it handles that workload without breaking a sweat. The 3200G's 4 threads will start to struggle. And the 4500 is actually cheaper right now. So on pure CPU performance, this isn't close.
The Wraith Prism Cooler doesn't factor into this category at all. It's a thermal solution, not a processor.
Integrated Graphics: Can You Game Without a Dedicated GPU?
Winner: AMD Ryzen 3 3200G
This is where the 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) has a genuine, meaningful advantage. It's the only product in this comparison that can actually run a display without a separate graphics card.
The Vega 8 iGPU has 8 compute units running at up to 1250 MHz. It's not going to run Cyberpunk 2077 at Ultra, but it handles CS:GO at 1080p medium settings at around 60 to 80 fps. Minecraft, Rocket League, older titles, and esports games all run acceptably. For a budget build where you genuinely cannot stretch to a discrete GPU right now, this matters enormously.
The 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) has zero integrated graphics. None. If you buy it without a GPU, you cannot connect a monitor. Full stop. That's not a criticism exactly, it's just a design choice AMD made to keep costs down, but it's a critical consideration for budget builders.
So if you're building a PC in stages and need something to work from day one without a graphics card, the 3200G is the only sensible option in this comparison. The Wraith Prism Cooler, again, doesn't apply here.
Cache is one of those specs that gets glossed over in budget CPU discussions, but it genuinely affects real-world responsiveness. The 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) carries 11MB of combined cache. The 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) has 6MB. That's nearly double on the 4500.
More cache means the CPU can hold more frequently accessed data closer to the cores, reducing the time it spends waiting on slower system RAM. In gaming, this shows up as more consistent frame times. In productivity work, it helps with tasks like large spreadsheet calculations or database queries where the same data gets accessed repeatedly.
Memory speed support also differs. The 4500 officially supports DDR4-3200, while the 3200G tops out at DDR4-2933. If you're buying new RAM anyway, faster kits will work better with the 4500. And for the 3200G specifically, faster RAM actually improves iGPU performance since the Vega 8 shares system memory bandwidth. So ironically, the 3200G benefits more from fast RAM but officially supports slower speeds.
The Wraith Prism Cooler has no cache or memory specs. It's a cooler.
Thermal Performance and Cooling: What Do You Actually Get?
Winner: AMD Wraith Prism Cooler
Right, so this is where the AMD Wraith Prism Cooler (199-999888) finally gets its moment. Both the Ryzen 3 3200G and Ryzen 5 4500 bundle a Wraith Stealth cooler in the box. The Wraith Stealth is a basic, no-frills cooler. It does the job for stock operation at 65W TDP, but it's not particularly quiet and has no RGB lighting.
The Wraith Prism is a step up. It features a larger heatsink, a higher-quality fan, and full RGB lighting with addressable LEDs. In thermal terms, the Wraith Prism can handle CPUs up to around 95W TDP comfortably, which means it has more headroom than either of these 65W chips actually needs. That translates to lower temperatures and quieter operation under load.
According to TechPowerUp's cooler testing, the Wraith Prism runs around 5 to 8 degrees Celsius cooler than the Wraith Stealth under sustained load on comparable CPUs. That's meaningful for long gaming sessions or sustained workloads.
But here's the honest take: if you're buying a new CPU from this list, you're already getting a Wraith Stealth for free. Spending an extra £39 on the Wraith Prism only makes sense if you care about RGB aesthetics or you're upgrading an existing AM4 build where the stock cooler has died or you want better thermals. It's not a bad product. It just has a narrow use case in this specific comparison.
Both CPUs use AM4, which is a positive. AM4 has been AMD's primary consumer platform since 2016 and supports a massive range of motherboards. But there are differences worth knowing about.
The 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) is based on Zen+ (12nm), which is two generations behind current AMD architecture. It launched in 2019. It works on virtually every AM4 board without a BIOS update, which is handy for older systems.
The 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) uses Zen 2 (7nm), which is a more modern process node. It launched in 2021 and offers better instructions-per-clock performance. Most B450 and X570 boards support it with a BIOS update. Some older B350 or X370 boards may not. Check your board's CPU support list before buying.
In terms of longevity, the 4500's 6 cores and 12 threads will stay relevant for longer. Games and applications are increasingly built around 6-core or more CPUs as a baseline. The 3200G's 4 cores with no hyperthreading is already behind the curve for gaming in 2026. You'll likely feel the need to upgrade sooner.
The Wraith Prism Cooler is compatible with AM4 and also supports AM3+ with an adapter, so it's actually the most broadly compatible product here in terms of socket support.
Value for Money: Which Is the Best AMD CPU Under £100 for Your Budget?
Winner: AMD Ryzen 5 4500
This is the most important category for anyone shopping the best AMD CPUs under £100. And honestly, the answer is pretty clear.
The 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) costs £61.99. The 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) costs £62.47. The 4500 is actually cheaper right now, and it delivers roughly double the multi-threaded performance. That's an extraordinary value proposition.
The only scenario where the 3200G offers better value is if you genuinely cannot afford any discrete GPU and need integrated graphics. In that specific situation, the 3200G's Vega 8 iGPU saves you from needing to spend anything extra on graphics. But if you already have a GPU or can stretch to even a budget card like an RX 6500 XT, the 4500 paired with a discrete GPU will massively outperform the 3200G plus its iGPU.
The AMD Wraith Prism Cooler at £38.71 is harder to justify in a value context. It's a decent cooler, but you're paying for RGB and slightly better thermals when both CPUs already come with adequate cooling. If you're spending £39 on a cooler, you might be better off putting that money toward a better GPU or more RAM.
According to AMD's official product page, the Ryzen 5 4500 is positioned as a mainstream productivity and gaming processor, and at its current street price, it punches well above that positioning.
Both CPUs come in AMD's standard retail box with the processor and bundled Wraith Stealth cooler. The packaging is proper and protective. The CPUs themselves are, as you'd expect, solid silicon dies in an AM4 PGA (pin grid array) package. Pins are on the motherboard socket, not the CPU, so there's less risk of damage during installation compared to Intel's LGA approach.
Owner feedback on Amazon for both CPUs is broadly positive. The Ryzen 3 3200G has a large number of reviews given its longer time on the market, with most users praising the iGPU capability and easy installation. The Ryzen 5 4500 has gathered strong reviews more recently, with users consistently impressed by the performance relative to price.
The Wraith Prism Cooler comes in a slightly more premium box with a window showing the cooler itself. Build quality is noticeably better than the Wraith Stealth, with a larger fan, more substantial heatsink, and the RGB ring around the fan. Installation uses AMD's standard retention mechanism, so it's straightforward on any AM4 board.
No major quality control complaints across any of the three products. This is a draw because both CPUs are essentially the same in terms of physical build quality, and the Wraith Prism wins on cooler quality but that's its entire purpose.
Look, it's worth being direct about the audience for each of these products because they serve genuinely different needs.
The 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) is for the builder who needs a complete, self-contained computing solution on the smallest possible budget. Think: a kid's first PC, a home office machine, a media centre, or a stepping-stone build where a GPU comes later. The iGPU is the whole point.
The 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) is for anyone building a proper gaming or productivity PC who already has or will buy a discrete GPU. It's the better processor in almost every measurable way, and it costs less. The use case is broader and the performance ceiling is higher.
The AMD Wraith Prism Cooler (199-999888) is for the existing AM4 owner who wants better thermals, quieter operation, or RGB lighting without buying a new CPU. It's an upgrade product, not a starting point. Buying it alongside a new CPU from this list doesn't make much sense unless you specifically want the RGB or plan to push the CPU hard in a warm case.
The 4500 wins this category because its use case is the most common and the value proposition is the strongest for the widest range of buyers looking at the best AMD CPUs under £100.
You need integrated graphics and cannot buy a discrete GPU right now. The Vega 8 iGPU is the only option in this comparison that lets you run a monitor without extra hardware.
You're building a basic home office or media PC where CPU performance beyond 4 cores is not a priority.
You're on an older AM4 board that may not support the Ryzen 5 4500 without a BIOS update and you'd rather avoid that complication.
Buy the AMD Ryzen 5 4500 If:
You have or plan to buy a dedicated GPU. The 4500's 6 cores and 12 threads will serve you far better for gaming and productivity than the 3200G's 4 cores.
You want the best raw CPU performance available in the best AMD CPUs under £100 category. It wins on multi-threaded performance by roughly double.
You want a chip that will stay relevant for longer. Six cores is the modern baseline for gaming in 2026, and the 4500 meets it comfortably.
Buy the AMD Wraith Prism Cooler If:
You already own an AM4 CPU and your stock cooler has failed or you want better thermal headroom for sustained workloads.
You want RGB lighting on your cooler and the Wraith Stealth bundled with your CPU does not offer that.
You're not buying a new CPU from this list and need a standalone cooling solution for an existing build.

Final Verdict: Best AMD CPUs Under £100
The 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) is the standout pick among the best AMD CPUs under £100 in 2026. It wins five of eight categories, costs less than the Ryzen 3 3200G at current prices, and delivers roughly double the multi-threaded performance. The only reason to choose the 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) is if you genuinely need integrated graphics and cannot add a discrete GPU to your build. The AMD Wraith Prism Cooler (199-999888) is a solid product in its own right, but it's an upgrade accessory rather than a primary purchase alongside a new CPU. If you're building fresh and want the best performance per pound in the sub-£100 bracket, the Ryzen 5 4500 is the clear recommendation.
The Ryzen 5 5600 provides the best gaming performance under £100, delivering strong frame rates at 1080p and 1440p with excellent single-threaded performance. For budget-conscious gamers prioritising value, the Ryzen 5 5500 offers slightly better price-to-performance with virtually identical gaming capability.
The Ryzen 7 3700X excels for streaming and content creation with eight cores providing sufficient multi-threaded performance for simultaneous gaming and streaming or video editing tasks. The additional cores justify accepting slightly lower gaming performance compared to six-core alternatives.
Most budget AMD processors ship with adequate stock coolers included, managing 65W thermal output reliably in average systems. The 4600G's 35W TDP requires minimal cooling even passively, whilst gamers seeking noise reduction or improved thermal headroom benefit from aftermarket solutions.
The Ryzen 5 3600 remains capable for gaming at 1080p and can be excellent value when discovered at genuine clearance prices, particularly for upgraders with existing AM4 motherboards. However, the newer Ryzen 5 5600 offers better single-threaded performance and efficiency when available at similar pricing.
Budget AMD processors under £100 use the AM4 socket, compatible with B450, B550, X470, and X570 motherboards. Older B350 boards require BIOS updates before recognising newer Ryzen chips. Budget B450 boards offer excellent value whilst providing all features most users require.
