Apple’s M5 Can Lose Up To 40% In FPS Due To Passive Cooling, MacBook Pro’s Active Fan Remains The Superior Choice For Sustained Workloads

The Apple Silicon continues to be efficient enough to the point that chipsets like the M5 can be used in portable Macs like the newly updated MacBook Air lineup for the majority of tasks without worrying about performance drops. However, when it comes to sustained workloads, which matter greatly, like gaming, an active cooling fan continues to tower over those silent passive solutions because the latest comparison shows that titles like Cyberpunk 2077, Baldur’s Gate 3, and others can lose up to 40 percent in framerates because of the cooling design difference alone.

An active cooling fan gives Apple’s M5 sufficient thermal headroom to operate at more than 2x the power limit of the passively-cooled version

It is essential to remember that the lack of a heat-dissipating fan doesn’t make the M5 MacBook Air unusable, but Apple leaves a ton of performance on the table by using a passive cooler on its less expensive hardware. In a detailed review by YouTuber Geekerwan, we looked at some gaming figures and found that an M5 with insufficient cooling can lose up to 40 percent of its framerate, though this depends on the game being played.

For instance, Cyberpunk 2077, which continues to be one of the more visually demanding titles around, pushes the M5 to its limit, with the MacBook Air only able to operate at a power limit of 9W compared to the MacBook Pro’s 20W. As expected, the increased power limit enables the M5 to deliver higher framerates, but even at less than 10W, the SoC showcases impressive performance in the AAA game.

Cyberpunk 2077 (low graphics present, 1,920 x 1,200, upscaling disabled)

• Actively-cooled M5 - Average of 51FPS, 1% lows of 41FPS
• Passively-cooled M5 - Average of 36FPS, 1% lows of 30FPS (33 percent faster than M4)
• Passively-cooled M4 - Average pf 27FPS, 1% lows of 22FPS

Cyberpunk 2077 (low graphics present, 1,920 x 1,200, MetalFX upscaling set to quality)

• Actively-cooled M5 - Average of 76FPS, 1% lows of 62FPS
• Passively-cooled M5 - Average of 54FPS, 1% lows of 44FPS (38 percent faster than M4)
• Passively-cooled M4 - Average of 39FPS, 1% lows of 32FPS

A similar scenario plays out in titles like Baldur’s Gate 3 and Elden Ring, where the M5 running on the MacBook Air starts off strong, maintaining the same FPS as the chipset powering the MacBook Pro, but that framerate slowly drops as the silicon approaches its thermal wall. However, we will say that, compared to the M4 MacBook Air, which utilizes the same cooling design, the M5 version registers significantly better framerate over a single generation, so kudos to Apple where it’s deserved.

Does this mean the M5 MacBook Air cannot be used when performing sustained workloads?

In both gaming and other intensive, sustained workloads, the M5 MacBook Air can handle these tasks, but you’ll need to be realistic about the level of performance you should expect. In a nutshell, these machines can handle pretty much everything you throw in their direction, but they will be slower than the M5 MacBook Pro because of one crucial difference. If you don’t mind these trade-offs, you’ll be happy to learn that Apple’s newest lineup now starts from $1,033 for the base model on Amazon, with discounts going as high as $84.
