To reduce noise levels below studio-quiet standards, the Mac Studio's M4 Max and M3 Ultra include a reinforced unibody aluminum chassis with improved airflow, dual centrifugal fans, and EMI-shielding gaskets. Even if their power envelope and raw performance differ significantly.
The M4 has a 40-core GPU (about 55 TFLOPS FP32) and a 14-core CPU (4 efficiency at 2.2 GHz, 10 performance up to 4.1 GHz). Max, which has a sub-62 °C surface-temperature profile and a 160 W sustained power. It also has a 1 TB NVMe SSD (8 GB/s read, 6.5 GB/s write) and a unified memory subsystem that supports up to 128 GB at 50 GB/s per 32 GB block. . provide up to 256 GB of memory at 90 GB/s per 32 GB block, aIn contrast, the M3 Ultra uses Apple's 1.5 TB/s UltraFusion.n SSD with a capacity of up to 16 TB (12 GB/s read, 10 GB/s write), an 80-core GPU with 64 Tensor accelerators (approximately 120 TFLOPS FP32, 240 Tensor TFLOPS), and a 28-core CPU (8 efficiency at 2.3 GHz, 20 performance at 4.2 GHz) all within a 320 W thermal envelope with noise levels below 24 dB. On benchmarks like Geekbench 6, the M3 Ultra nearly doubles or outperforms the M4 Max thanks to DaVinci Resolve 8K and ResNet50 training. The M4 Max multi-8K display installations are more appropriate for developers looking for a compromise between peak performance, efficiency, and quieter thermals, while the M3 Ultra is most suited for VFX pipelines and on-premise AI/ML workloads. Artists and video editors seeking studio-quality work at a lower cost.
Apple's Mac Studio portfolio achieves unprecedented levels of performance and expandability. In addition to pushing raw compute numbers to the limit, the most recent M4 Max and M3 Ultra models improve thermals, power efficiency, and system integration.
