MacBook Pro 16 M5 Max Review: 18% Faster Than M5 Max 14-inch

Apple’s latest M5 Max chip is delivering a noticeable performance boost in the larger MacBook Pro 16-inch model, exceeding the capabilities of the M4 Max found in the 14-inch version. Initial benchmarks indicate the 16-inch MacBook Pro with the M5 Max is approximately 18% faster in multi-core Cinebench 2024 tests compared to the previous generation M4 Max in the 14-inch model. This performance gain is achieved even although operating in the ‘Automatic’ power mode, which also results in quieter operation.

Thermal Management and Performance Consistency

A key area of improvement appears to be thermal management. The Cinebench 2024 tests show the CPU cores in the 16-inch MacBook Pro consuming 78/65 watts during a benchmark run – significantly more than the 14-inch model. This increased power draw, coupled with the larger chassis allowing for better heat dissipation, contributes to sustained performance. The Cinebench 2024 benchmark, based on the Redshift rendering engine used in Cinema 4D, runs for 10 minutes to specifically test for thermal throttling, a common issue in laptops where performance degrades as components heat up. Check-Mac.com details how the extended test duration provides a more realistic assessment of sustained performance compared to shorter benchmarks.

Graphics performance also sees a lift. Using the 3DMark Steel Nomad test, the M5 Max in the 16-inch MacBook Pro demonstrated a 12% advantage over the M5 Max in the 14-inch model, and a 21% improvement over the older M4 Max in the 16-inch. Importantly, the GPU performance remains stable under sustained load, a characteristic that wasn’t consistently observed in the smaller model. The 14-inch model experienced performance drops of up to 7.4% in ‘High Performance’ mode and 25% in ‘Automatic’ mode, suggesting the larger chassis and improved cooling are effectively mitigating thermal throttling.

Benchmarking and Performance Context

The M5 Max is a system-on-a-chip (SoC) launched in March 2026, designed for premium laptops like the updated 14-inch and 16-inch MacBook Pro lineup. NotebookCheck provides detailed specifications, noting configurations with up to a 40-core GPU, 128 GB of RAM, and 8 TB of PCIe 5.0 storage. The initial Geekbench 6 results, reported by MacRumors on March 5, 2026, showed a multi-core CPU score of 29,233, surpassing the Mac Studio’s M3 Ultra chip (27,726) and establishing the M5 Max as the fastest Apple silicon chip to date. It also outperformed all consumer PC processors in the Geekbench database at the time of testing.

The single-core performance of the M5 Max (scoring 4,268 in the same Geekbench 6 test) is comparable to the regular M5 chip, and represents the highest single-core score of any consumer PC processor. In terms of graphics, the M5 Max with a 40-core GPU achieved Metal scores of 218,772 and 232,718, slightly lower than the highest-end M3 Ultra but significantly higher than the M4 Max.

Implications for Creative Professionals

These performance gains are particularly relevant for professionals working with demanding applications like video editing, 3D rendering, and complex simulations. The improved thermal management in the 16-inch model allows the M5 Max to sustain higher clock speeds for longer periods, resulting in faster render times and smoother performance during intensive tasks. The stability of GPU performance under load is also crucial for these workflows, preventing unexpected slowdowns or crashes.

The difference in performance between the 14-inch and 16-inch models highlights the importance of chassis design and cooling solutions in maximizing the potential of powerful processors like the M5 Max. While the 14-inch model offers portability, the 16-inch provides a more favorable environment for sustained performance.

Further Testing and Long-Term Performance

While these initial benchmarks are promising, further testing is needed to assess the long-term performance and reliability of the M5 Max. The testing team is currently evaluating whether the ‘High Performance’ mode impacts sustained performance over extended periods. The 10-minute duration of the Cinebench 2024 test is designed to reveal potential thermal limitations, but real-world workloads may present different challenges.

The initial findings suggest the M5 Max is a strong fit for the larger MacBook Pro 16-inch, and the performance difference compared to the 14-inch model is significant. As more data becomes available from independent reviews and user experiences, a clearer picture of the M5 Max’s capabilities will emerge.

Next Steps: Ongoing testing will focus on evaluating sustained performance under various workloads, including video encoding, 3D rendering, and complex simulations. The team will also monitor CPU and GPU temperatures to assess the effectiveness of the cooling system and identify any potential thermal throttling issues. Results will be compared to other high-end laptops and desktop workstations to provide a comprehensive assessment of the M5 Max’s performance.
