The new mid-range Arrow Lake processor, featuring 14 cores and a focus on cool and quiet operation.

Core Ultra (Arrow Lake) architecture and 14 cores support modern desktop computing workloads.
The processor runs at a 4.2 GHz performance-core base frequency and can reach up to 5.2 GHz max turbo frequency.
LGA 1851 compatibility includes DDR5 memory up to 6400 MT/s and PCIe 5.0 and 4.0 connectivity.
The Intel Core Ultra 5 245K is a mid-range Arrow Lake desktop CPU for the LGA 1851 platform, featuring 14 cores, integrated graphics, up to 5.2 GHz max turbo frequency, DDR5 memory support, PCIe 5.0/4.0 compatibility, and a 125 W processor base power; a CPU cooler is not included.
The reviewer concludes that while the processor is more energy-efficient and runs cooler than its predecessor, its performance is inconsistent and its gaming performance is disappointing, making it hard to recommend compared to AMD or 14th Gen Intel alternatives.
The review finds the CPU to be a poor value, noting it offers disappointing results for gamers and inconsistent productivity performance that rarely justifies its price over existing alternatives like the Core i5-14600K or Ryzen 7 7700X.
The reviewer describes the processor as a versatile and economical all-rounder that provides a good balance of price and performance, particularly praising its energy efficiency and strong CPU performance, despite slightly lagging behind the older i5-14600K in gaming scenarios.
The reviewer notes that while the processor offers improved power and thermals and good content creation performance, its inconsistent gaming performance and various platform bugs mean it cannot be recommended without fixes.
