Intel Core Ultra 5 245K Review

$309 MSRP

Intel's mid-range Arrow Lake. 14 cores in a 125W envelope is impressive. Solid all-rounder when you want Intel.

Architecture & Overview

The Intel Core Ultra 5 245K is built on the Intel Arrow Lake (LGA 1851) architecture, fabricated on a TSMC 3nm process and released in 2024. It packs 14 cores / 14 threads (6 performance + 8 efficiency) with a base clock of 4.2 GHz and boost up to 5.2 GHz. The cache hierarchy — 26MB L2 plus 24MB L3 — is the single biggest determinant of gaming performance on modern chips: gaming workloads are overwhelmingly cache-sensitive, which is why AMD's 3D V-Cache variants dominate gaming benchmarks despite often having lower raw clocks than their non-X3D siblings.

Power-wise, the chip is rated at 125W TDP, drops into an LGA 1851 socket, and supports DDR5-6400. The recommended cooler is a 240mm AIO or premium air — no stock cooler is included, so budget for one. Integrated graphics: Intel Graphics (4 Xe cores).

Benchmark Context

In our database this chip posts 24,800 points in Cinebench R23 multi-threaded and 2,150 single-threaded. Cinebench is a strong proxy for productivity performance (rendering, compilation, video encoding) — the multi-threaded score scales with core count, while the single-threaded score tracks per-core speed and is the best predictor of gaming performance alongside L3 cache size.

Pros & Cons

What we like

  • Strong value (78/100) — performance per dollar is well above average

What to watch out for

  • No stock cooler — budget for a cooler separately

GPU Pairing Recommendation

Best paired with a mid-range GPU like the AMD Radeon RX 7800 XT or similar. Going higher on the GPU would mean leaving GPU performance on the table at competitive framerates.

Frequently Asked Questions

What motherboard do I need for the Intel Core Ultra 5 245K?
The Intel Core Ultra 5 245K uses the LGA 1851 socket. LGA 1851 means Z890 or B860 chipsets for Arrow Lake.
What cooler does the Intel Core Ultra 5 245K need?
Official recommendation: 240mm AIO or premium air. No cooler is included — you need to buy one separately. With a 125W TDP, a quality dual-tower air cooler is plenty — no need for liquid cooling.
What RAM should I pair with the Intel Core Ultra 5 245K?
Supported memory: DDR5-6400. DDR5-6400 CL32 or faster is recommended for Arrow Lake — Intel has a wider memory controller and benefits from raw bandwidth.
Does the Intel Core Ultra 5 245K have integrated graphics?
Integrated graphics: Intel Graphics (4 Xe cores). Usable for basic desktop work and display output in the absence of a discrete GPU, but not a gaming iGPU.
How many cores does the Intel Core Ultra 5 245K have?
14 physical cores and 14 threads. The layout is 6 performance cores and 8 efficiency cores. Boost clock tops out at 5.2 GHz.

Where to Buy

The Intel Core Ultra 5 245K launched at $309 MSRP. Check Amazon for current pricing — prices fluctuate frequently and bundles with motherboards can be a great deal.
