i9 13900K Vs i9 13900KS: Overall Gaming Performance

Having discussed the performance of these processors in individual games, in this section of the i9 13900K vs i9 13900KS comparison, we will take a look at the average performance of these processors during our tests.

Framerate

• The i9 13900K averaged 191 FPS over the 7 games tested, while the i9 13900KS was barely ahead with 192 FPS on average.
• 1% lows had the same story to tell. The 13900K had 1% lows of around 160 FPS, whereas the 13900KS had 1% lows of 161 FPS.

Overall, the performance of these chips do not hold a significant difference. We would be hard-pressed to find out that anyone but the most skilled of gamers could discern the performance delta between these two processors.

In terms of price to performance, the 13900K delivers 16.5% more power for each dollar you spend according to the launch MSRP of these chips and the performance we have measured in our tests.

Take a look at our guide on overclocking if you are curious to see the limits you can push your gaming setup to.

Power Consumption

• The 13900K had an average power consumption of 121 watts during our benchmarks.
• The 13900KS drew 126 watts on average in our tests.

There is a measurable difference between the power consumption of both processors, though it is still not enough of a difference to buy one processor over another.

The performance per watt of the 13900K was about 3.5% better than the 13900KS, meaning you get almost equivalent performance on the non-S version whilst having a marginally lower power draw.

Temperatures

• The average temperature of the 13900K was about 66.8°C during our tests.
• The 13900KS averaged a temperature of 68.5°C in our tests.

This metric had the biggest disparity in our tests, though it is hardly a deciding factor because both of these processors lie well within safe temperature margins.

The higher temperatures of the KS are due to its incredibly high clock speed, making it generate more heat.

If you want to make sure that your CPU stays within safe temperature ranges while you game, take a look at our guide on CPU temperatures while gaming.

Price And Availability

The Intel Core i9 13900K has an MSRP of $589, while the KS retails for around $689.

These processors are recent enough to be available at any big tech store of your choosing (like MicroCenter) though their high-end nature might make them hard to come by anywhere else.

Which One Should You Go For?

After covering all the metrics related to these two CPUs, we will now examine the target audience or user base of both processors in this section of the i9 13900K vs i9 13900KS comparison.

Starting with the 13900KS, it is not a processor for anyone concerned with value. It gives top-of-the-line specifications with silicone that is abnormally perfect. This CPU is the epitome of the law of diminishing returns, but for folks looking for the absolute best performance in a processor, the i9 13900KS is the way to go.

On the other hand, the i9 13900K offers a much more reasonable solution to ultra-high-end gamers. It offers about the same performance as the i9 13900KS while costing a hundred dollars less. This leads us to recommend this processor to most people looking to get a CPU between these two options, though there might be better options for gaming in the overall gaming landscape.
