Intel’s Core i9-13900KS hits 6GHz out of the box, but there’s a catch

Intel has just launched the Core i9-13900KS, a CPU to end all CPUs — at least in this generation. This is Intel’s most powerful chip right now, fully poised to top the list of the best processors on the market.

This doesn’t just mark yet another entry into Intel’s impressive CPU arsenal. The Core i9-13900KS stands out as the first consumer processor to hit 6GHz out of the box without extra overclocking. To hit that peak, however, it’s going to consume a whole lot of power.

Sneak Peek: 6 GHz Intel Core Out-of-the-Box Demo

Intel’s new Core i9-13900KS is the top processor in the Raptor Lake lineup. It sports the same hybrid core architecture, meaning a mix of performance (P) cores and efficiency (E) cores, and it has plenty of both: eight P-cores and 16 E-cores for a total of 24 cores and 32 threads.

The clock speeds are different based on the core type. The maximum frequency for P-cores is 6.0GHz, but E-cores are limited to 4.3GHz. Moreover, the Core i9-13900KS can only reach the elusive 6GHz mark if the Extreme Power Delivery Profile that requires a massive 320 watts of power is used. This means that the Core i9-13900KS isn’t just the fastest CPU out right now, it’s also the most power-hungry.

You don’t even need to use the “Extreme” power profile — even at regular settings, the CPU consumes more power than the Core i9-13900K. It has a processor base power (PBP) of 150 watts and a maximum turbo power (MTP) of 253W. Lastly, we’re getting a huge (68MB) combined cache.

Suffice it to say that you’ll need an extremely good cooler and a beefy power supply to support this CPU. It’s also likely to be paired with one of the top graphics cards out right now, meaning that even more cooling and power are going to be required.

The official price of the CPU is $699, but so far, we’re seeing it priced higher. You can get the Core i9-13900KS on or .

With the Core i9-13900KS out right now, Intel is certainly winning the race against AMD — but things may change soon enough. With the Ryzen 9 7950X3D on the horizon, AMD is well-positioned to compete, and it’s going to be an exciting battle to watch.

Intel 13th-gen Raptor Lake arrives just in time to hit back at AMD
Intel's CEO holding a Raptor Lake processor.

Intel today revealed its 13th-gen Raptor Lake processors during its Innovation 2022 event, heating up the already hot battle between AMD and Intel. Although these new chips share a lot with the previous generation under the hood, Intel is promising more cores, higher clock speeds, and performance that will catapult 13th-gen chips to the top of the best CPU rankings.

Before digging in, here's a quick look at specs for the three Raptor Lake processors coming. Some specs are official, while others have been compiled from specs posted by Intel a couple of weeks back (though not confirmed).

AMD Ryzen 9 7950X vs. Intel Core i9-12900K: Two flagships face off
A hand holding the Ryzen 9 7950X in front of a green light.

When the Intel Core i9-12900K came out in late 2021, it was Intel's first true flagship CPU since its 2018 Core i9-9900K. It actually beat AMD's flagship Ryzen 9 5950X in both single- and multi-threaded performance, and the 12900K remains the fastest mainstream desktop CPU to this day and one of the best CPUs in general.

But AMD now has its Ryzen 9 7950X. It blows past AMD's previous-generation offerings, there's no doubt about that. Even against Intel's most powerful CPU to date, however, AMD's latest processor shows a big jump in performance.

Ryzen 7 7700X vs. Intel Core i7-12700K
The Ryzen 7 7700X CPU.

Looking for a CPU upgrade for your gaming machine? We’ve got some good news: AMD's Ryzen 7000 Zen 4 CPUs are set to deliver significant boosts in performance compared to the previous generation and long-awaited support upgrades for the latest connections.

The Ryzen 7 7700X chip, in particular, looks like an excellent combination between a performance upgrade and affordability. But that also sets it against the similarly priced Intel Core i7 12700K -- a chip from the 12th-generation Alder Lake series Intel released in late 2021. Just how do these processors stack up, especially for gamers? Let’s take a look at what we know.
