Finding the best processor for your gaming PC can be a tricky business. There are just so many options: Intel or AMD? How many threads do I need? Is 3D V-cache worth it? With Amazon Prime Day in full swing once again, there are lots of CPU deals to choose from.
But have no fear: I’ve built literally dozens of PCs for all sorts of purposes, and I’m here to deliver the definitive Prime Day deal when it comes to CPUs. The AMD Ryzen 7 5800X is better than half price on Amazon in both the US and UK - in fact, it’s never sold for less than this in the UK.
We gave this chip a whopping five out of five stars in our Ryzen 7 5800X review, and the chip still holds up well today. Sure, it’s been superseded by the Ryzen 7 7800X3D now, but that chip’s a lot more expensive - especially given the current discount. You can pick up the 5800X for $217 at Amazon US or £180.97 at Amazon US, both stellar discounts on this excellent mid-range CPU.

AMD Ryzen 7 5800X UK deal
AMD’s affinity for gamers is well-documented, with Team Red constantly striving to deliver great PC gaming hardware. At the time it was released, the Ryzen 7 5800X was a blessing, delivering great results across the board in gaming, single-core workloads, and power efficiency. I actually have this exact CPU in my gaming desktop at home, and it's never caused me any bottlenecking issues, even with an RTX 4000 GPU.
You also shouldn’t need to spring for a new motherboard if you’re upgrading from an existing Ryzen chip, since the 5800X uses the same AM4 socket as earlier generations - unlike the new Ryzen 7000 chips, which use the AM5 socket and would therefore require you to buy an expensive new mobo too.
At 52/57% off the retail price (that’s the US/UK discounts respectively), this is hands-down the best processor deal I’ve seen during Amazon’s Big Deal Days sale event, to the point where it’s impossible for me to not recommend it. If you’re contemplating an upgrade to an outdated CPU or looking to build a PC from scratch, this is definitely a deal you should snap up.
