M1 Ultra
The M1 Ultra processor is based on Apple’s Arm architecture, which is designed for mobile devices and laptops. Apple has optimized its Arm-based chips for performance and efficiency, but it comes with some limitations in terms of software compatibility.
Cores and Threads
AMD EPYC
AMD EPYC processors offer a wide range of core and thread counts, ranging from 8 cores and 16 threads to 128 cores and 256 threads. This flexibility allows users to choose the optimal configuration for their specific workload requirements.
M1 Ultra
The M1 Ultra processor features a massive 20 cores and 64 threads. While this is impressive for a mobile chip, it falls short of the core and thread count offered by high-end AMD EPYC processors.
Clock Speed
AMD EPYC
AMD EPYC processors have a base clock speed of 2.4 GHz, which can turbo boost up to 4.0 GHz or higher. This provides a balance between performance and power efficiency.
M1 Ultra
The M1 Ultra processor has a base clock speed of 3.2 GHz, which can turbo boost up to 4.3 GHz. While this is slightly faster than AMD EPYC processors, the difference is not significant for most HPC applications.
Memory and Cache
AMD EPYC
AMD EPYC processors support up to 8 memory channels, allowing for a maximum of 2 TB of DDR4 memory. They also feature a large L3 cache of up to 256 MB per socket.
M1 Ultra
The M1 Ultra processor supports unified memory, which combines system memory and graphics memory into a single pool. It has a maximum memory capacity of 128 GB and a large L3 cache of 64 MB.
Power Consumption
AMD EPYC
AMD EPYC processors are designed to be power efficient, with a typical power consumption of 180-225 watts. This makes them suitable for high-density computing environments.
M1 Ultra
The M1 Ultra processor is highly power efficient, with a typical power consumption of 60 watts. This makes it an excellent choice for portable devices and energy-conscious data centers.
Performance Benchmarks
Single-Core Performance
In single-core performance benchmarks, the M1 Ultra processor consistently outperforms the AMD EPYC processor. This is due to its higher clock speed and optimized Arm architecture.
Multi-Core Performance
In multi-core performance benchmarks, the AMD EPYC processor typically takes the lead, especially in applications that can leverage a large number of cores and threads.
