Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite

Gaming Performance: iGPU

Despite updating the main bulk of our CPU test suite for 2023 and beyond, we've not had a chance to test every integrated graphics chip in our stack of CPUs. As a result of this, we've included limited results for our iGPU-based gaming tests, although it is more than enough to get to grips with improvements in Raptor Lake performance.

As a reminder, We are using DDR5 memory on the Core i9-13900K, the Core i5-13600K as well as Intel's 12th Gen (Alder Lake) processors at the following settings:

• DDR5-5600B CL46 - Intel 13th Gen
• DDR5-4800 (B) CL40 - Intel 12th Gen

All other CPUs such as Ryzen 5000 and 3000 APUs were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.

Final Fantasy 14

World of Tanks

Borderlands 3

Far Cry 5

Grand Theft Auto V

Strange Brigade (DirectX 12)

For both 13th and 12th Gen Core series processors, Intel is using the Xe-LP based 770 HD graphics processor. This means the overall integrated graphics performance between the two is almost identical.

In our integrated (iGPU) graphics testing, the power of Intel's Raptor Cove cores combined with more E-cores does show a distinct, but negligable advantage when using Intel's 770 HD graphics. This advantage is clear in Final Fantasy 14 where more cores and more CPU power are advantageous for performance.

Looking at the iGPU performance of both the Core i9-13900K and Core i5-13600K in our other tests, the Core i9 performs best out of Intel's chips, but in games where graphical power is required, the AMD 5000 series APUs do come out best. The Core i5-13600K also performs marginally worse than the Intel Core i9 12th Gen series, but this is to be expected.
