Cache and power consumption

The Core i5 13400 features a 20 MB shared L3 cache and 1280 KB per-core L2 cache. The Core i5 13600K, on the other hand, boasts a larger 24 MB shared L3 cache but a smaller 2 MB per-core L2 cache. This indicates that the Core i5 13600K prioritizes overall cache capacity, while the Core i5 13400 focuses on per-core cache performance.

Power consumption, as indicated by the Thermal Design Power (TDP), also varies between the two processors. The Core i5 13400 has a TDP of 65 W, making it a more power-efficient option. This lower power draw translates into reduced heat generation and less demanding cooling requirements. The Core i5 13600K, in contrast, has a higher TDP of 125 W, reflecting its increased power demands due to the higher core count and clock speeds.

Additional features

Both processors share the LGA 1700 socket and have integrated graphics (Intel UHD Graphics 730) with similar base and boost clock speeds. However, the Core i5 13600K boasts more shading units (256 vs. 192), potentially offering a slight graphics performance advantage for basic graphics tasks.

One notable feature exclusive to the Core i5 13600K is its ECC (Error-Correcting Code) support. ECC provides enhanced data integrity by detecting and correcting memory errors, making it a valuable feature in professional applications where accuracy is paramount.

Which CPU is better for a virtual PC build?

For a virtual PC build, the Core i5 13600K might be a better choice due to its higher core and thread count, which can handle multiple virtual machines more efficiently.

Both CPUs use the LGA 1700 socket, so they’re compatible with motherboards that support this socket. However, always check for the latest BIOS updates to ensure compatibility.
