Apple M5 Pro (18-core)
Apple's first 'Fusion Architecture' chip fuses two dies into one SoC. The top M5 Pro configuration pairs 6 Super Cores with 12 Performance Cores (18 total) and a 20-core GPU, dropping the traditional low-power efficiency-core cluster entirely.
Pros
- New Fusion Architecture delivers up to 30% higher multithreaded performance than M4 Pro
- Neural Accelerator in every GPU core pushes AI GPU compute over 4x versus M4 Pro
- Memory bandwidth up to 307GB/s, versus M4 Pro's 273GB/s
- Native Thunderbolt 5 support
Cons
- No dedicated low-power efficiency-core cluster, unlike M4 Pro
- 64GB memory ceiling unchanged from M4 Pro
- New two-die 'Fusion' packaging has no long-term track record yet
