CPU Comparison
AMD Ryzen Threadripper PRO 9945WX vs Apple M1 Max
A side-by-side comparison of specs, performance and value. The AMD Ryzen Threadripper PRO 9945WX is a 12-core, 24-thread workstation processor designed for professionals who require extreme single-threaded performance, eight-channel memory bandwidth, and full I/O expandability but do not need the core counts of higher-tier chips.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Exceptional for single-threaded tasks, though multi-threaded throughput is naturally lower than 32 or 64-core models.
Excellent performance in pro apps thanks to high single-thread speed and strong multi-core scaling, especially for code builds, photo editing, and light-to-medium 3D.
Efficiency
With only 12 active cores, power efficiency is excellent relative to the workload, fitting well within the 350W envelope.
Industry-leading performance per watt enables long battery life in MacBook Pro and low power draw in Mac Studio under typical pro workloads.
Specialized Performance
AI / ML
- Limited by 12 cores for parallel AI tasks.
- However, PCIe 5.0 lanes allow for massive accelerator arrays.
- 16-core Neural Engine accelerates Core ML models for imaging, video analysis, and audio tasks.
- Unified memory allows running mid-sized models and batching within device memory.
- Large-scale model training is better suited to data center GPUs; M1 Max excels at inference rather than training.
Content Creation
Gaming
- Boosts up to 5.7 GHz, rivaling top-tier consumer CPUs.
- Ideal for high-refresh-rate gaming workstations.
- Supports multiple GPUs via extensive PCIe lanes.
- Integrated GPU scales well in Apple-optimized games and titles supporting Metal, but driver ecosystem is limited compared to Windows/PC GPUs.
- AAA titles often require reduced settings or resolutions.
- eGPU support is not available on Apple Silicon, limiting future GPU upgrades.
