The Core i9-13900K: An Overview

Dominating the lineup is the Core i9-13900K, Intel’s new flagship chip that offers an impressive balance of power and efficiency. At its heart, the i9-13900K is an iteration of the previous-gen Alder Lake design, with several key enhancements. It boasts 24 cores, consisting of 8 performance cores (P-cores) and 16 efficiency cores (E-cores), and 32 threads. The inclusion of more E-cores results in a substantial boost in multi-threaded performance, making the i9-13900K a force to be reckoned with.

Priced To Compete

With an MSRP of $589, the Core i9-13900K is competitively priced, especially when compared against its key rival, AMD’s Ryzen 9 7950X. The Ryzen 9 7950X, which also offers impressive performance, is priced at $699. This makes the Core i9-13900K not just a performance beast, but also a more cost-effective option for those looking to maximize their computing power without breaking the bank.

The Design: An Evolution of Alder Lake

The 13th Gen Core lineup is built on Intel’s 7nm process and its x86 performance hybrid architecture. This design philosophy, first introduced with Alder Lake, involves the use of both high-performance P-cores and energy-efficient E-cores. The P-cores are built for tasks that demand high performance, while the E-cores handle low-priority, low-performance tasks. This allows the processor to manage energy consumption effectively without compromising on performance.

More Cores, More Power

The Core i9-13900K stands out for its increased core count. Compared to its predecessor, the Alder Lake Core i9-12900K, which featured eight P-cores and eight E-cores, the Core i9-13900K boasts eight P-cores and a whopping 16 E-cores. This increase in core count contributes to the chip’s enhanced performance capabilities.

Enhanced Cache Sizes and Clock Speeds

The new Raptor Lake Core i9 also includes larger L3 and L2 caches, with 36MB of L3 cache and 32MB of L2 cache. These increased cache sizes play a pivotal role in boosting the chip’s performance. Additionally, the clock speeds of both the P-cores and the E-cores have been ramped up. The P-cores in the Core i9-13900K operate at a speed that is 600MHz faster than in the Core i9-12900K, while the E-cores operate at a speed that is 400MHz higher.

Higher Memory Speeds

The maximum supported memory speed has also been increased from 4,800MHz on Alder Lake to 5,600MHz on Raptor Lake. This improvement allows the i9-13900K to handle memory-intensive tasks with greater efficiency.

Balancing Performance and Power Consumption

While the Core i9-13900K is packed with power, it’s also designed to manage power consumption effectively. Despite the increase in resources, the Core i9-13900K is not drastically more power-hungry than its predecessor. It does consume more power and runs hotter than one might prefer, but these factors do not hinder its performance capabilities.

The Z790 Chipset

Along with the Raptor Lake processors, Intel has also launched a new chipset – the Z790. It supports an additional eight PCI-E 4.0 lanes compared to the Z690, and it can also support an extra USB 3.2 Gen 2×2 port. The chipset’s integrated Wi-Fi controller now operates on an Intel Killer Wi-Fi 6E design.

The Test Setup

For our review, we tested the Core i9-13900K on a Gigabyte Z790 Aorus Master motherboard. We used two 16GB sticks of DDR5 memory in a dual-channel configuration, operated at the Core i9-13900K’s maximum officially supported memory speed of 5,600MHz. We used a Cooler Master MasterLiquid PL240 Flux 240mm water cooler to ensure the chip didn’t overheat.

CPU Performance

In terms of raw CPU performance, the Core i9-13900K was able to outperform all competing CPUs in nearly all tests. AMD’s Ryzen 9 7950X offered some stiff competition, coming close to matching the Core i9-13900K in some tests. However, in terms of pure CPU performance, the Core i9-13900K emerged as the clear winner.

Gaming Performance

In gaming tests, the Core i9-13900K delivered strong performance but didn’t stand out significantly from other chips. In certain games, the Core i9-13900K managed to secure the lead, delivering superior performance at various tested resolutions. However, in other games, the performance was on par with other high-end chips.

Integrated Graphics Performance

The Core i9-13900K features an integrated graphics processor (IGP) identical to the one found in many Alder Lake processors. Performance tests revealed that the Core i9-13900K delivered the best performance among all chips with the same IGP.

Power Consumption and Thermals

As expected, the Core i9-13900K consumes more power than its predecessor. During our tests, the system with the Core i9-13900K drew more power than any other processor we’ve tested to date. The chip also ran hot during the tests, frequently reaching temperatures of 100 degrees Celsius. However, these factors were not problematic enough to prevent the processor from delivering top-notch performance.


The Core i9-13900K represents a significant step forward for Intel. With its enhanced performance capabilities, efficient power consumption, and competitive pricing, it has earned its place as the fastest consumer-oriented CPU currently available, making it an excellent choice for users seeking top-tier performance. Whether you’re looking to upgrade your current system or build a new one, the Core i9-13900K is a processor worth considering.
