The Intel Core Ultra 5 245K has recently demonstrated some impressive capabilities, particularly in its integrated GPU performance. In a remarkable overclocking feat, an overclocker known as “Arabus” pushed the iGPU of this chip to an astonishing 3 GHz from its usual 1.9 GHz, showcasing the potential hidden within Intel’s latest mid-range processors.
Despite its modest stock clock speeds, the 4 Xe-Core iGPU pulled off a significant performance uplift in the 3DMark Time Spy Graphics test. Initially yielding scores around 2100–2200 points, the overclocking endeavor propelled the score to an impressive 3336 points, marking a substantial 54% increase. This performance rivals the desktop GTX 1650, suggesting the iGPU can support high settings at 1080p in many popular games.
The cooling solution for this achievement wasn’t state-of-the-art but rather an Arctic Freezer 4U-M air cooler, sporting an aluminum heatsink and dual fans. Despite not being the pinnacle of air cooling, it effectively maintained temperatures at a manageable 64°C, underscoring the chip’s efficiency and the cooler’s effectiveness. This achievement points to the possibility of even higher performance with more advanced cooling solutions like a premium AIO to prevent any threat of thermal throttling.
Arabus’s configuration also involved the disabling of E-cores, leaving the CPU to operate on 6 performance cores. This could have contributed to maintaining the temperature within comfortable limits, ensuring the CPU’s stability even during extended sessions.
The success story of the Core Ultra 5 245K suggests a promising frontier for gaming without the need for discrete GPUs, potentially reshaping expectations for mainstream computing power. With further potential in both CPU and GPU overclocking, this chip could serve as a solid option for those seeking a cost-effective yet powerful solution for gaming and other graphically demanding tasks.
