Our verdict
The Ryzen 7 5800X3D Processor takes the performance lead with a 8% higher overall score, driven by its 8 shader cores, 96 MB of memory, and 4,500 MHz TFLOPS of compute power. In gaming benchmarks at 1440p, it delivers roughly 8% more frames per second across demanding titles like Counter-Strike 2 1080p and Cyberpunk 2077 1080p.
However, the Core Ultra 5 245K Processor tells a compelling value story. At $309 versus the Ryzen 7 5800X3D Processor's $449 price tag, it costs 45% less while delivering performance that's only 8% behind. Its 24 MB of memory is still more than enough for 1440p and even 4K gaming in most titles.
Our recommendation: for the majority of gamers targeting 1440p or even 4K with upscaling enabled, the Core Ultra 5 245K Processor is the smarter purchase. The Ryzen 7 5800X3D Processor only makes sense if you need the absolute maximum performance for native 4K ray tracing, professional 3D rendering, or AI workloads where the extra VRAM and compute power provide a tangible advantage.
