CPU Comparison
Apple M3 Pro vs Intel Core Ultra 9 185H
A side-by-side comparison of specs, performance and value. The Apple M3 Pro is a 3 nm ARM-based system-on-chip with an 11- or 12-core CPU and 14- or 18-core integrated GPU, designed for professional MacBook Pro workflows that demand strong single-threaded performance, hardware-accelerated ray tracing, and high efficiency rather than maximum multi-core throughput.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Excellent single-core and good multi-core performance for typical pro apps, with snappy responsiveness and very good efficiency.
16 cores and 22 threads handle heavy creative workloads easily.
Gaming
Strong 1080p and capable 1440p gaming with good efficiency; GPU core and bandwidth cuts versus M2 Pro mean some titles may not scale as well at higher resolutions.
Arc 128EU is a huge upgrade over older Intel iGPUs, capable of 1080p medium gaming.
Virtualization
Capable for light VMs, but memory bandwidth and core count are lower than M2 Pro/M3 Max, which can matter for heavy multi-VM workloads.
Good for running VMs on a laptop, though limited by thermal constraints.
Efficiency
Among the most efficient Pro-class SoCs Apple has shipped; does more CPU work per watt than earlier Pro chips.
Meteor Lake is efficient, but the 185H is a 45W part and can get warm.
Specialized Performance
AI / ML
- 16-core Neural Engine up to ~18 TOPS
- Good for on-device inference and Core ML workloads
- Not designed for training large models; GPU-focused workloads may favor M3 Max
- 11 TOPS NPU is sufficient for background blur and noise cancellation
- Does not meet Copilot+ PC standards (requires 40+ TOPS)
- AI tasks often fall back to CPU/GPU for maximum performance
Content Creation
Gaming
- Hardware ray tracing improves lighting and reflections in supported titles
- Strong 1080p and 1440p performance with Metal-optimized games
- Some GPU benchmarks show regressions vs M2 Pro due to fewer cores and lower bandwidth
- Arc 128EU graphics allow decent 1080p gaming without a dGPU
- Supports hardware ray tracing (though limited)
- Performance depends heavily on laptop cooling solution
