Key Takeaways
1. The MacBook Air 13 features a slightly slower M5 SoC with 8 GPU cores, compared to the 10 GPU cores in larger models.
2. The MacBook Air operates without a fan, which can lead to performance dips under heavy workloads, stabilizing around 8 Watts.
3. During gaming, power consumption is low, dropping between 6.9 and 7.2 Watts while still achieving playable frame rates.
4. The MacBook Air 13 is noted as the most efficient laptop tested, with overall power usage, including the display, at just 19 Watts.
5. Lowering graphics settings and using MetalFX upscaling allows for a smoother gaming experience in demanding titles while avoiding throttling.
We recently had a chance to check out the new Apple MacBook Air 13, featuring the base configuration powered by the M5 SoC. Unlike the 15-inch version of the MacBook Air or the MacBook Pro 14 with the M5, the base Air 13 comes with a slightly slower M5 SoC, which has 8 GPU cores rather than the 10 found in its larger counterparts. Despite this, the performance remains impressive, and we were especially amazed by its efficiency during our gaming tests, where the SoC consumed only 7 to 8 Watts.
Performance Under Load
The MacBook Air operates without a fan, meaning its performance can dip under heavy workloads, causing the M5 to stabilize at around 8 Watts during combined tasks. You might think the processor holds steady at this range (7-8W) while gaming, but that’s not entirely true. For instance, while playing Cyberpunk 2077, the SoC’s consumption drops to between 6.9 and 7.2 Watts, which is still below the maximum of 8 Watts. This power level allows for a frame rate of 19.6 fps at 1080p with ultra settings, and this performance remains consistent even after an hour of play. If you lower the graphics settings a bit and utilize MetalFX upscaling, you can enjoy a smooth gaming experience in demanding titles like Cyberpunk 2077 or Baldur’s Gate 3, with power usage ranging from 7.5 to 7.8 Watts, all while avoiding throttling.
Efficiency and Comparison
This efficiency makes the compact MacBook Air stand out as the most efficient laptop in our records by a significant margin, without falling into unplayable frame rates. For the entire system, including the display, we measured just 19 Watts, which again showcases its efficiency. On the other hand, the M5 SoC with 10 GPU cores in the actively cooled MacBook Pro 14 isn’t as efficient but does provide a boost in gaming performance.
