@tps3443 I also have an 8-core GPU in my MBA. Your experience of the 8-core running faster than the 7-core runs counter to what I had heard - that there was little difference in performance after the machine heated up. Presumably because 8 cores generates more heat than 7 cores...
Macs Fan Control recently released an update that made it compatible with M1 Macs. While the MBA has no fans, Macs Fan Control still provides a handy readout of the laptop's thermal sensors. And Skyrim SE was pushing temps up into the upper 90s. But not the GPU; rather it was the CPU that was getting toasty. So for the time being I've limited parallels to 3 CPU cores and that seems to keep temps to 90C and below, while also preventing the hard throttling I was seeing. Some judicious tweaking of the graphical settings is still necessary for (mostly) smooth gameplay.
How do you get the air to circulate underneath the MBA? Some sort of stand, like
@Fuchal was talking about? Or do you use a DIY solution? I have invested in a small, cheap USB fan, but it doesn't move huge amounts of air.
@Fuchal, you wouldn't happen to have a link to the stand you were talking about, would you?
I have seen the 8 core GPU run cooler than a 7 core GPU (From comparing some MacBook Air’s my self) My whole point to why the 8 core gpu throttles less, and offers better performance when both are warm, is because the 8 core GPU is the premium silicon of the two. The same 8 core GPU silicon that goes in that of the MacBook Pro 13”. This silicon is obviously binned. And binned silicon will use less voltage, in turn producing less power, and creating less heat.
Now this is just a theory, but it holds a lot of water too though.
The MacBook Air 13” Pro M1 was given the better silicon. Apple even offered this silicon for Air buyers that wish to pay the small premium for it. And the premium is worth it for sure.
Now I have only tested one 7 core MacBook Air, (wasn’t my machine) but I have owned and tested (2) 8 core GPU MacBook Air machines. And the results were very similar and repeatable, in the same ambient temperatures. The casing in the same area on the 8 core gpu model was drastically cooler in specific areas. As the performance was noticeably better as well. (Steam FPS counter)
I am surprised that almost every reviewer looked right past this. After equilibrium is reached the 8 core gpu runs cooler and faster in an amount more than that of just 1 more core. And some reviews do reflect this. I have seem
numbers showing like
This is only a theory, but it does make sense. The best silicon goes in a Pro M1. And the Air is available to get it too. (And it’s worth it!
Now going from 7 core gpu to an 8 core gpu will generally offer a 14-15% advantage with an 8 core gpu. But on a 7 core machine I tested, vs an 8 core gpu would always throttle less..Turning in to 20-23% faster gaming performance that was easily repeatable in Rust, and Euro Truck Simulator 2.
These numbers are pretty drastic. Instead of 35FPS you can get 42FPS with only a 20% increase in performance. Which was always the minimum (That I saw)
Now, my testing doesn’t mean crap.. (YOUR MILEAGE MAY VARY ) You could possibly have a golden 7 core gpu air that runs super cool under a heavy sustained load with minimal throttling at all. So, then you’re only left with the difference of 7 VS 8.
Now some simpler games do not throttle either machines. Rust, and Euro truck sim 2 both use ram, cpu, and full GPU usage all the time. So they will heat these machines up. I have never tested (Less demanding) or ( Easy to render games) Probably negligible or minimal difference at all.
Anyways, I spent a lot of time testing this and comparing them. I do hope this information was intriguing for you.
