The M4 Processor takes the performance lead with a 13% higher overall score, driven by its 10 shader cores, 0 MB of memory, and 4,400 MHz TFLOPS of compute power. In gaming benchmarks at 1440p, it delivers roughly 18% more frames per second across demanding titles like Counter-Strike 2 1080p and Cyberpunk 2077 1080p.

However, the M4 Processor tells a compelling value story. At $599 versus the M3 Processor's $599 price tag, it costs $0 less while delivering performance that's only 13% behind. Its 0 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 M4 Processor is the smarter purchase. The M3 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.
