Apple M5 Pro (18-CPU 20-GPU) vs NVIDIA N1X

Last updated:
The Apple M5 Pro (18-CPU 20-GPU) is a high-performance processor based on the M5 architecture, designed for professional users in the desktop segment.

Manufactured using an efficient 3-nm process, this chip features 18 CPU cores and an integrated Apple M5 Pro (20 Core) graphics unit. A memory bandwidth of 307 GB/s enables high AI performance for complex calculations. In synthetic benchmarks, the model shows significantly higher single-core and multi-core performance compared to the competing model.

The architecture ensures optimized energy efficiency, which reduces the thermal load. Additionally, the chip supports PCIe 5.0 for fast data transfer rates of external storage solutions. The evaluation of the price-performance ratio remains reserved for the specific requirements of the professional market due to the lack of available market prices.

The NVIDIA N1X is based on the GB10 Grace Blackwell architecture and was primarily designed for compute-intensive workstations.

It also utilizes an efficient 3-nm manufacturing process and offers an integrated NVIDIA N1X (GB20B) graphics solution. Thanks to a memory bandwidth of 301 GB/s, good AI performance for various applications is guaranteed. Advantages in gaming scenarios and graphical simulations arise from the Blackwell architecture, as this technology is specifically designed for graphics calculations.

The hardware includes 24 MB Level 2 and 32 MB Level 3 cache, which supports data flow under high load. Although the CPU performance in benchmarks falls behind that of the Apple model, the NVIDIA N1X offers high flexibility through PCIe 5.0. Since market prices are missing, the price-performance ratio depends on the individual need for Blackwell-specific functions.
