Not a happy time in the world of CPU deals this week. After a steady couple of weeks of gradually falling prices, many CPU deals have started moving in the opposite direction now, making it a bad time to get a good CPU bargain. There are still a couple of CPU deals worth picking up, though, all of which you’ll find listed below. And to help you see just how much of a deal (or not) it is, we’ve rounded up the best prices for all of today’s best gaming CPUs so you can see how they compare against one another. So whether you’re looking for the best Intel CPU deals or the best AMD Ryzen CPU deals for building a new PC, these are the cheapest CPU deals around right now.
Upgrading your CPU isn’t the easiest operation when it comes to upgrading your PC, and if your CPU is more than a couple of years old, then you’ll most likely need to a whole new motherboard for it, too, as certain CPUs are only compatible with specific types of motherboards.
You’ll find everything you need to know in our What motherboard do I need for my Intel or AMD Ryzen CPU? article, but the short version is that AMD Ryzen CPU buyers should consider getting either an AM4 motherboard with either a B550 or X570 chipset, as this will ensure future compatibility with AMD’s next gen CPUs. Intel CPU buyers will need a LGA1151 motherboard with a 300-series chipset (such as the B360 or Z390) if you’re buying a 9th Gen Coffee Lake processor, or an LGA1200 motherboard with a 400-series if you’re going for one of their new 10th Gen Comet Lake chips.
You’ll find more info on how to get a great CPU deal at the bottom of this article if you want a bit more info on what to look out for – and remember, if you’re in need of more PC components for your new build, then make sure you have a look at our regularly updated Graphics card deals, SSD deals and Gaming monitor deals pages, too. For now, though, here are the cheapest CPU deals of the week.
CPU deals of the week
Intel CPU deals:
Intel Core i3-9100 deals:
- Intel Core i3-9100F – £63 from Amazon UK
- Intel Core i3-9100F – $74 from Walmart
- Intel Core i3-9100 – £107 from CCL Online
- Intel Core i3-9100 – $109 from Amazon US
While we haven’t reviewed the i3-9100, its predecessor – the Core i3-8100 – is a solid if unremarkable quad-core CPU. Really, you should be buying an AMD CPU if you don’t have a lot of money to spend, as you’ll get much better gaming performance across the board. However, if you’re dead set on Intel, this is the entry-level CPU to buy – and you can save even more by opting for the cheaper F model, which is exactly the same as the regular 9100, but doesn’t have any integrated graphics. As a result, you’ll need to pair it with a graphics card, but you’ll likely be doing that anyway if you’re building a new gaming PC.
Intel Core i5-9600K deals:
Up a tenner in the UK and a dollar in the States, Intel’s Core i5-9600K may have been replaced by the Core i5-10600K now, but if you want to keep costs down and are conscious about your CPU’s power consumption, this is still a great gaming CPU in its own right. It comfortably outperforms the AMD Ryzen 5 3600X, even if you do pay a bit more for the privilege. Just make sure you’ve got enough budget for a cooler, as it doesn’t come with one in the box.
Intel Core i5-10600K deals:
Intel’s first mid-range 10th Gen chip is an absolute beast of a gaming CPU, and if you’re looking for a rock-solid gaming PC that really packs a punch, then you won’t be disappointed. It’s markedly faster than the previous generation, though given how new it is, don’t expect the above prices to drop any time soon. It’s also a real power hog, so make sure you’ve got enough cash for a decent cooling solution and a beefy PSU to go with it. Stock of the regular K model is exceedingly low in the US right now, but we’ve managed to find the KF model (which is the same just minus any integrated graphics support), so as long as you’re pairing this with a graphics card you should get an identical gaming experience.
Intel Core i7-9700K deals:
- Intel Core i7-9700K – £326 from Amazon UK (via third party)
- Intel Core i7-9700K – $372 from Amazon US
Normally, we’d shy away from third-party sellers on Amazon, but this one still has plenty of stock and a hefty discount, letting you buy one for £35 less than the nearest rival. While the i9-9900K below is technically as good as 9th Gen Intel chips get, the performance increase just isn’t big enough for us to recommend it over the Core i7-9700K. Even with a new generation of Intel chips now in the wild, this is a great performer – though you will probably want to consider liquid cooling if you plan on trying your hand at overclocking.
Intel Core i7-10700K deals:
- Intel Core i7-10700K – £338 from Amazon UK (via third party)
- Intel Core i7-10700K – $335 from Newegg
We’ve not been able to review the Intel Core i7-10700K yet, but you’re pretty much guaranteed performance between the i5-10600K and i9-10900K which should not be a let down. As with said chips, however, this is a brand new CPU, so you’re unlikely to see bargain basement prices any time soon. The US price here is a bit special, but be quick, as it only runs until Monday as part of Newegg’s 4th July celebrations.
Intel Core i9-9900K deals (DO NOT BUY):
- Intel Core i9-9900K – £430 from Amazon UK (via third party)
- Intel Core i9-9900K – $496 from Amazon US
Under $500 for the first time, the i9-9900K still isn’t really worth considering. Yes, it was the fastest chip available in late 2018, but the gains were marginal and now it’s eclipsed by Intel’s 10th Gen CPUs. Bluntly, until it drops in price dramatically, there’s no reason to pop this in your PC ahead of its rivals above and below.
Intel Core i9-10900K deals (DO NOT BUY):
If you want the best of the best, you’ll have to be prepared to put a lot of cash up front, though it is pleasingly lower than the Core i9-9900K’s original launch price. This is the best gaming CPU money can buy right now, but until we get a sample of the i7-10700k to test, we won’t know exactly how much better. Both the links above are currently out of stock, but given you’ll have to pay a comical amount at the few places where the CPU can still be bought, you’re best off waiting this one out.
AMD CPU deals:
AMD Ryzen 3 3300X deals:
The Ryzen 3 3300X is hands down our favourite budget CPU for two reasons: it’s fast and it’s cheap. How fast? Well, it runs gives Intel’s Core i5-9600K chip a run for its money on most of the benchmarks for half the price, which is pretty hard to argue with. It’s still rare as hen’s teeth to find stock, so prices are slightly inflated unfortunately. Amazon UK do, thankfully, have it for its normal price (albeit on back order).
AMD Ryzen 5 3600 deals (DO NOT BUY):
With the Ryzen 3 3300X still hard to come by at its regular price, the Ryzen 5 3600 is still a decent CPU, but its gaming performance is pretty much identical to its Ryzen 3 3300X sibling. For the difference in cost, we’d go for the Ryzen 3 3300X, but if you can’t wait for more stock to arrive then this’ll do you just fine.
AMD Ryzen 5 3600X deals:
Up in price on both sides of the Atlantic this week, the Ryzen 5 3600X is only marginally better than the 3600 above, but if you’ve got a few more quid left in your budget then you’ll squeeze a few more frames per second with a Ryzen 5 3600X. Again, the Ryzen 3 3300X isn’t too far behind, so if you’re looking to save money, then scroll back up. However, if you also use your PC for lots of photo and video editing, then the Ryzen 5 3600X’s two extra cores make it well worth the extra expense.
AMD Ryzen 7 3700X deals:
AMD’s Ryzen 7 3700X isn’t the fastest Ryzen CPU you can buy right now, but it is the best value out of all its top-end gaming CPUs. Not only is it more energy efficient, but the sharp increase in price you’ll face with either the 3800X or 3900X doesn’t really justify the relatively modest leap in performance in our eyes. It’s simply the best balance between price and performance available right now for AMD CPU buyers.
AMD Ryzen 7 3800X deals (DO NOT BUY):
While it’s technically better than the Ryzen 7 3700X above, our benchmarks showed its performance to be a mixed bag in terms of value for money. It’s down $10 in the US this week, so at least prices are moving in the right direction, but we’d still recommend buying the Ryzen 7 3700X instead.
AMD Ryzen 9 3900X deals (DO NOT BUY):
This is one of AMD’s top Ryzen processors, but boy is it pricey. Really, this 12-core CPU is geared toward creative media professionals rather than PC gaming, and we think you’ll be much better off getting the Ryzen 7 3700X if you want to stick with AMD, or even switching to a 10th Gen Intel chip.
How to get a great CPU deal:
Upgrading to one of today’s best gaming CPUs can make a surprising difference to your PC’s overall gaming performance, particularly if you tend to play games at a resolution of 1920×1080. The difference becomes a lot less marked at 1440p and 4K, though, so if you regularly play games at these resolutions, then you can save yourself a lot of money by opting for a mid-range CPU instead of an expensive high-end one.
If you regularly stream games online, though, then you’ll want a CPU with lots of cores, as your PC needs to be very good at multi-tasking to stream smoothly. This means you’ll probably have to find a bit more budget for something like one of Intel’s Core i7 CPUs or AMD’s Ryzen 7 chips, but you’ll thank yourself later for finding the extra cash.
The question, of course, is what type of gaming CPU you should go for? Intel or AMD? A lot of your decision making will be determined by what kind of motherboard you have, although if your PC is more than a few years old, chances are you’ll need to buy a new motherboard anyway. If you’re building a new PC from scratch, then it’s a bit easier, as you can simply pick the best gaming CPU you like the sound of and buy the appropriate motherboard to match.
There are pros and cons to both Intel and AMD. Intel CPUs generally offer the better gaming performance overall, but they tend to be more expensive than their AMD equivalents. AMD CPUs also come with their own coolers, and all of them are unlocked for overclocking, which isn’t necessarily the case with every Intel CPU.
That’s why the AMD Ryzen 3 3300X is the RPS CPU of choice in our £1000 RPS Rig build (that, and it’s an incredible CPU in its own right, too), but as a general rule, the more money you’ve got to spend means you’re probably better off going with an Intel CPU rather than an AMD one – especially if getting the best possible gaming performance is your number one priority.
