Intel Core i9-13900K review – is it worth it?

The Intel Core i9-13900K may not be the newest high-end processor made by Team Blue anymore but time hasn’t slowed this chipset down at all. Built upon the LGA 1700 socket, this leading Raptor Lake model is more than fast enough for today’s intensive games and the demands of productivity and creative workloads, too. We think it’s one of the best CPUs for gaming even in 2024 and it’s easy to see why; let’s get into all the details down below.

Intel Core i9-13900K price

The Intel Core i9-13900K carries an MSRP of $589 since its release but that’s only one side of the story. That’s because this enthusiast-level chipset is available discounted frequently in 2024 down to around $520 from retailers such as Amazon and Newegg, saving you $60. For context, that’s the same pricing as the previous iteration, the i9-12900K, which also uses the same socket.

In terms of its rivals, the closest competition with the Intel Core i9-13900K is the AMD Ryzen 9 7900X3D which you can find for $599, slightly more expensive than Team Blue’s premiere offering. Whether the discount is enough to sway you away from the more recent Intel Core i9-14900K will depend on your usage case. At the time of writing, the most recent flagship has yet to receive any kind of offers to the same extent.

Intel Core i9-13900K key design

As mentioned above, the Intel Core i9-13900K is once again built for the pre-existing LGA 1700 socket instead of switching up socket types. It’s the second generation hybrid architecture processor meaning it’s running a combination of E-cores (efficiency cores) and P-cores (performance cores) for better power optimization. Speaking of, the 13900K features a total of 24 cores (eight P-cores and 16 E-cores) as well as 24 threads for a truly leading amount when compared to its competition.

That extends to the base and boost clock speeds as well. The Intel Core i9-13900K is capable of boosting up to 5.8 Ghz straight out of the box which was unheard of back then. That’s since been outdone by the 14900K (6 GHz) and the brand-new 14900KS (6.2 GHz) but we’re still talking about an incredibly fast chipset all the same. There’s also 36MB of L3 cache to aid processor-intensive tasks such as gaming and rendering as the largest, but slowest cache type on the silicon.

An advantage that Intel’s 13th Gen frontrunner has over its most recent rival chipsets is the fact that this i9 processor can utilize both DDR4 and DDR5 RAM. While an enthusiast is likely to want the higher speeds afforded by the latter, the option of having both supported shouldn’t be shrugged off, especially if you’re upgrading your PC bit by bit, saving you money as you go. With its 125W TDP, this processor is at the upper end of power usage, but still a good way behind the 170W of AMD’s Zen 4 non-3D lineup.

Intel Core i9-13900K gaming performance

In the testing conducted by WePC’s Jack Howarth, it’s clear that the Intel Core i9-13900K is still more than competitive when it comes to powering today’s games. This is most evident in titles such as Cyberpunk 2077, Resident Evil Village, CS2, and Days Gone. Provided you have one of the best graphics cards you shouldn’t notice any kind of bottleneck.

Our test system is running the i9-13900K with an ASUS ROG Ryujin II 360mm AIO CPU cooler on an ASUS ROG Maximus Z970 Extreme motherboard with 16GB DDR5 RAM @ 5600 MHz with the Fractal Design ION+860W PSU.

Intel Core i9-13900K synthetic benchmarks

It’s a similar story with the synthetic performance through our industry-standard suite of benchmarking tools such as CPU Z, Cinebench R23, and Geekbench with strong figures for single-core but especially powerful multi-core performance. We’ve got the full details down below.

When stress-testing we noticed that the Intel Core i9-13900K actually got up to and beyond 100° even with a 360mm AIO installed. While it’s unlikely you will notice this level of heat dissipation when gaming or rendering, it’s worth investing in one of the best CPU coolers for 13900K in case. Don’t skimp on the cooling, and we don’t recommend an air cooler here either.

Is the Intel Core i9-13900K worth it?

As far as desktop processors go, the Intel Core i9-13900K is incredibly powerful but we would argue it’s only worth choosing over the newer Intel Core i9-14900K if you can find it at a substantial discount. While it’s no longer the flagship CPU it once was, there’s no faulting the performance it offers for the money, just be sure to utilize one of the best CPU coolers to keep those core temps in check.

Conclusion

Even well over a year after its release, the Intel Core i9-13900K remains a powerful chip when paired with either Z690 or Z790 motherboards and should be a decent upgrade from Alder Lake or those coming over from pre-LGA 1700 boards. If you’re after max frame rates in today’s games then the chipset has proven its worth especially when twined with the likes of the RTX 4080 Super and RTX 4090.

Generation-on-generation, the performance gains are notable over 12th-gen processors as Raptor Lake excels with its higher core count and higher frequency clock speeds, but there’s a major caveat. That’s the fact that it was released back in 2022 and we’ve already had a successor, the 14900K, come in and excel past what this chipset can do in terms of maximum turbo power, single-core performance, and multi-core performance as our Intel Core i9-14900K vs Intel Core i9-13900K feature goes into.
