Incredible Price to Performance: The Core i5 13600K is one of the best CPUs that consumers can currently buy. Performance wise, it offers comparative metrics to the Core i9 12900K which is a CPU with twice the amount of cores at double the price point. Its difficult to argue with the price considering how powerful the CPU is.

Supported by Older Motherboards: The biggest benefit of picking up a 13th-Gen CPU, is that can consumers can leverage great performance without having to spend a fortune on a motherboard. The 13th-Gen CPUs are supported on 12th-Gen boards which are fairly cheap in comparison, with a simple BIOS update.

DDR4 and DDR5 Memory Support: Intel’s 13th-Gen platform offers support for both DDR4 and DDR5 RAM, providing consumers plenty of options when it comes to upgradeability, or for those that are price conscious.

Things We Don’t Like

Overclocking requires stronger VRMs: For those that plan on overclocking their 13600K, you’ll need to plan around this by picking a motherboard that has strong VRM power phases. These motherboards can be pricier if you plan on pushing your CPU quite far in terms of clock speed.

Not the Best Option for Workstations: Productivity workstations often require more cores and higher clock speeds so that high-demand tasks and applications can run well. Although the 13600K is ideal for gaming, users with a workstation system may want to purchase a Core i7 or i9 to achieve better metrics.


Intel’s Core i5 13600K is arguably, one of the best CPUs on the market. Consumers get access to a CPU that offers incredible metrics at all resolutions in games, with some reasonable legs in productivity applications. Consumers don’t need to worry about insane thermals, and the overall platform cost is pretty reasonable compared to other market options. For these reasons, we’ve given this CPU the title of the best overall CPU in our roundup.

4. Best High-Performance Option – Intel Core i9 13900K

👑The best performing CPU.

Intel Core i9 13900K


For our final CPU pick, we’ve chosen Intel’s Core i9 13900K. This CPU is quite literally the best gaming CPU we’ve ever seen, offering exceptional performance in pretty much anything you throw it at. 4K gaming poses no issue to this CPU, and high intensity workloads such as video editing or 3D-rendering won’t make this CPU break a sweat. The 13900K is perfectly positioned to handle big workloads and when you’re not working you can stick on your favourite game and ramp everything up to max.

The RTX 4080 is a very powerful GPU, and thus it needs the cores, threads, and clock speed to be able to keep up with the capability of this GPU. We would primarily recommend sticking to a high-end workstation PC if you’re picking up the 13900K, as all of the other options can handle 4K gaming with minimal issues. The Core i9 13900K’s power and performance will effectively be wasted on anything less than a high-intensity workstation.

Choosing the Right CPU

Before we jump into our recommended picks there are some factors to consider before choosing your CPU. Choosing the right CPU for your system is a fine balance between use-case, and pricing. You don’t want to buy a CPU that you ultimately won’t need, as this money can be better spent on more RAM, a better looking case or faster storage.

You want to ensure the CPU you choose has enough cores and threads for the games you play, and more importantly fast single-threaded performance for the best single-threaded metrics possible, typically the most important indication when it comes to gaming performance. Chips with more cores will also work better in tasks such as streaming, video editing or rendering, making designs like the i7 and i9 also a good shout for content creators.

AMD vs Intel

One of the biggest debates around any table of tech heads when it comes to building a PC is often Team Blue (Intel) vs Team Red (AMD). Over the past few years both of these manufacturers have been in a constant battle to retain the performance crown, each delivering a plethora of solid CPU options to the market. Both AMD Ryzen 7000 processors and Intel’s 13th Generation are strong choices, with our reviews leaning more towards Intel for the time being.

AMD look to have the better architecture and platform going forward, though, which makes them one to watch again in the very near future. Currently, they are also held back by the platform costs of their processors, with AMD motherboard costing significantly more than their Intel counterparts. As time goes on, these board prices should drop and things will start to level out a bit more.

Intel CPUs

For quite some time, Intel has been the go-to for gamers due to their per-core performance. With Intel’s most recent 13th generation models offering excellent clock speeds out of the box, alongside a significant improvement to cores. As a general rule, many users tend to opt for an Intel CPU over AMD because of their strong all-round performance. If you’re building a multi-faceted system (a gaming and workstation PC), Intel is definitely the manufacturer we’d recommend at the moment for an RTX 4080 build.


AMD, on the other hand, lag behind a little at present, but do bring an impressive lineup to the market. Their Ryzen 3000 and 5000 CPUs allowed them to hit back at Intel for the first time in nearly 10 years, though some of that progress has seem a little stunted by the launch of Ryzen 7000.

Factors to Consider

Now that we’ve cleared the sensitive argument of Intel vs AMD, we’ll briefly cover some other factors you should consider before buying a CPU to pair with an RTX 4080. We’ve broken down the most important considerations below:

Motherboard Compatibility

Choosing a compatible motherboard is probably the most important point to consider, as this will determine whether your build actually works. Without hammering on about chipsets and motherboard types, we recommend you check out the table below, along with some further reading on motherboard compatibility. We’ve put together a Motherboard Compatibility guide on the latest CPUs, which covers all of the compatible sockets and chipsets for both Intel and AMD.

Motherboard Form Factors
CPU RangeSocket TypeCompatible Motherboards
Intel 13th-GenLGA1700Z790, Z690, B660, H670, H610
Intel 12th-GenLGA 1700Z790, Z690, B660, H670, H610
AMD Ryzen 7000AM5X670E, X670, B650E, B650
AMD Ryzen 5000AM4X570, X470, B550, B450, A520

As you can see from the table, Intel 13th and 12th generation CPUs work on all of the 600 and 700 series motherboards, giving you a wide range of choice, both in terms of features and budgets. For AMD Ryzen 7000 and 5000, the sockets are entirely different and therefore they are not compatible with each other. If you’re looking at upgrading from Ryzen 5000 to 7000 you’ll need to pick up an entirely new motherboard and DDR5 RAM for the new platform as Ryzen 7000 is DDR5 only.

For this reason you’ll want to pick up a motherboard that has some extra usability features such as PCI-E armour. This will minimise any damage to your PCI-Express pins should the GPU sag, and in worst case, reduce the risk of snapping or breaking the entire slot. Although we can’t imagine this happening on most boards, GPU sag is a real killer for PCI-E Slots, and with the weight of these new cards, you’ll want to cover all of your bases.

Platform Longevity

The longevity of the CPU platform you’re using is a bit of a complicated factor. This effectively boils down to: Can you upgrade your CPU on the same platform to get better performance? If the answer is no, then you might want to reconsider your options.

MSI MEG X670E ACE Motherboard

The reason why I’ve included this is because the biggest downside to the RTX 4080 and 4090 GPUs is that they’re effectively too good. The CPU to some extent ends up bottlenecking the GPU when it comes to frame output, because the graphics card is simply so quick. This can make a build that keeps CPU agreeability in mind particularly attractive.

DDR4 vs DDR5

Besides Intel vs AMD, DDR4 vs DDR5 is one of the other major arguments in the industry right now. You might see major publications, or manufacturer marketing saying “you need DDR5 for gaming” and frankly, this is total utter rubbish. DDR5 is currently pretty weak in terms of its performance gains, and simply not worth the extra cash.

Corsair Vengeance RGB DDR4 32GB

DDR4 is the go-to for 90% of consumers right now, something which makes Intel’s options (chips that support both memory standards) an attractive option. AMD’s Ryzen 7000 lineup sadly only supports DDR4 memory.

Over time we’ll see the prices for DDR5 memory drop, making it advantageous for those that already have a DDR5 motherboard, as they’ll start to see performance gains with improved memory. But until the prices drop and the performance increases, we’d recommend sticking to a high speed DDR4 kit. For those looking to make their PC stand the test of time, you’ll want to pick up DDR5, but be aware that there aren’t any major benefits as of right now when it comes to performance.
