• ARM (Apple M-series, Snapdragon X Elite): Used in MacBooks and newer Windows ARM laptops

Apple M-Series Overview:

• M1 / M1 Pro / M1 Max / M1 Ultra
• M2 / M2 Pro / M2 Max
• M3 / M3 Pro / M3 Max
• Excellent performance-per-watt, unified memory

Snapdragon X Series:

• Snapdragon 8cx Gen 3, Snapdragon X Elite
• ARM-based, highly efficient, catching up to Apple’s M-series

Intel CPU Labels:

• U: Ultra-low power
• P: Performance-balanced
• H/HS: High performance (thin and light/gaming)
• HX: Desktop-grade for heavy multitasking/gaming

AMD CPU Labels:

• Ryzen 3/5/7/9 with suffixes similar to Intel: U, H, HS
