CPU Comparison
Apple M1 Ultra vs Intel Xeon w3-2535
A side-by-side comparison of specs, performance and value. The Apple M1 Ultra is the most powerful chip in Apple's first-generation Apple Silicon lineup, engineered by fusing two M1 Max dies through the proprietary UltraFusion interconnect. With 20 CPU cores, up to 64 GPU cores, a 32-core Neural Engine, and up to 128GB of unified LPDDR5 memory delivering 800 GB/s bandwidth, it targets the most demanding professional workflows in a compact desktop form factor.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Exceptional multi-threaded performance for creative and professional applications, handling the heaviest workloads with ease.
Strong multi-threaded performance for professional content creation and engineering workloads, especially when ECC and vPro are valued.
Gaming
Capable of running many titles at high settings, but the macOS game library is limited and no external GPU support exists.
Not a gaming-focused CPU; capable of high-refresh 1080p/1440p gaming but often outperformed by gaming-optimized desktop CPUs at similar price points.
Virtualization
Competent virtualization through Parallels and UTM, but ARM-based VMs have better compatibility than x86 VMs.
Good for small-to-medium VM counts on workstations, but limited to 10 cores and 4 memory channels compared to higher-end Xeon W-3500/Threadripper Pro options.
Efficiency
Remarkable performance-per-watt compared to competing x86 workstations, delivering more work per unit of energy consumed.
Moderate efficiency; 185 W base and 222 W max turbo are reasonable for a 10-core workstation part but higher than modern 8-core desktop CPUs at lower power.
Specialized Performance
AI / ML
- 32-core Neural Engine accelerates on-device machine learning inference at up to 22 trillion operations per second
- 800 GB/s memory bandwidth benefits large language model inference
- 128GB unified memory enables loading large AI models that exceed typical GPU VRAM
- No dedicated tensor cores in the traditional NVIDIA CUDA sense
- Apple Core ML and Metal Performance Shaders provide software-level acceleration
- Includes Intel AMX and AVX-512 for improved AI inference
- Suitable for CPU-based inference and light training workloads
- Not competitive with dedicated AI accelerators or high-core-count server GPUs
Content Creation
Gaming
- 64-core GPU handles most macOS-native titles comfortably at 1440p
- Limited game library on macOS compared to Windows
- Rosetta 2 translation layer adds minor overhead for x86 games
- No support for external GPUs via Thunderbolt
- AAA titles running through CrossOver or Parallels may have reduced performance
- High single-core turbo (up to 4.6 GHz) helps smooth gameplay
- Lacks E-cores and hybrid optimizations of newer gaming CPUs
- Best suited as a workstation CPU that can also game, not the reverse
