The Core i9-13900K is the second-best CPU Intel has ever made, at least we consider it to be. And now you can get 34% off for Prime Day. We all know that the 14th generation CPUs were met with criticism on launch for being a mere “refresh” of what already existed because the 14th gen brought small performance upgrades for a larger asking price. Referencing that point, the 13900K remains a higher performance-per-dollar CPU than the 14900K.

The 13900K contains the second generation of the big.LITTLE split-core architecture that offers greater efficiency when the CPU is met with less demanding workloads. It is a well-rounded CPU that has a total of 8 P-cores and 16 E-cores, on the high end, the 13900K can boost to 5.8 GHz without breaking too much of a sweat.

Why you should consider this i9-13900K Prime Day deal

In our i9-13900K review, we did note that the former flagship is indeed “still pricey in 2025” – however, Prime Day has come along to try and prove us wrong. Anyway, there are a few things to consider when picking a new CPU, here are the main selling points of the 13900K:

  • Enhanced Gaming Experience: This CPU is designed for gamers, offering high frame rates and exceptional responsiveness, making it a perfect choice for competitive gaming.
  • Future-Proof Technology: With support for the latest DDR5 memory and PCIe 5.0, the i9-13900K is built to take advantage of the newest technologies, ensuring longevity and performance for future applications. It is important to note that LGA 1700 support ends at the 14th generation.

Get this 13900K deal now for just $416

The 13900K certainly sells itself as one of the best CPUs that Intel has ever made, but you do pay for it, even when it’s discounted. Recently, Intel fixed an issue causing the 13th and 14th generations to burn up via sustained overvolting, causing instability.

So if you do decide to pick up one of these CPUs, ensure you install the latest BIOS update that carries the microcode fix. This CPU is phenomenal in terms of value for money and performance, especially if you want top-shelf intel performance for a little less than the current flagship offering, the i9-14900K.
