Intel Core Ultra 5 245K Specifications and Performance Analysis

The Intel Core Ultra 5 245K is based on the Arrow Lake-S architecture and is manufactured using the 3 nm process at the TSMC foundry. It is compatible with the LGA 1851 socket used by Z890, B860, W880, Q870, H810 chipsets and supports PCIe Gen 5, 20 Lanes (CPU only), as well as DDR5 memory with speeds of up to 6400 MT/s across Dual-channel memory. This processor features a hybrid core configuration with 6 performance cores operating at a base clock of 4.20 GHz and boosting up to 5.20 GHz, alongside 8 efficiency cores running at a base clock of 3.60 GHz and boosting up to 4.60 GHz, for a total of 14 threads. It is equipped with 192 kB of L1 cache, 3072 kB of L2 cache, and 24 MB of L3 cache. The efficiency cores feature 96 kB of L1 cache and 4096 kB of L2 cache.

This CPU is designed for a mainstream desktop platform. It supports consumer-grade memory configurations and modern expansion standards, making it suitable for everyday computing, gaming, and productivity workloads.

The Intel Core Ultra 5 245K has a base TDP of 125 W and a moderate maximum TDP of 159 W. Most mid-range aftermarket air coolers are sufficient for thermal control. This processor is also suitable for small form factor builds, which often have limited airflow.

For users who require integrated graphics, this CPU includes the Arc Xe-LPG Graphics 64EU, which features 4 GPU cores. It operates at a base clock of 0.30 GHz and boosts up to 1.90 GHz. This makes it suitable for systems without a dedicated GPU, capable of handling everyday tasks and running older or less demanding games. Integrated graphics can also accelerate specific workloads even when a discrete GPU is installed.
