If Apple hadn't crippled the SSD on the base model (to the point where in real world usage it can perform much worse than the 256GB M1 MBA,) I think people would be a lot more willing to let the throttling (#3) go. Of these problems I think #1 is by far the most serious in terms of the M2 MBA. it still throttles to a similar degree as the old design despite there being an "easy fix" The fact that Apple completely redesigned the MBA from the ground up and. The fact that the M2 throttles a bit even in the MBP with a fan which is disappointing thermal performance compared to the M1.ģ. The reduction (by half) of the storage performance on the base, 256GB model (that will inevitably sell the most,) that can result in an extreme reduction in performance (far more than CPU/GPU throttling) when the machine has to page the SSD.Ģ. So why are people loosing their **** over the M2 (MBA)?ġ. The throttling was accepted as it was clear they just stuck the new chip in the old chassis, removed the fan, and got great performance. The M1 SOC in the OG Apple Silicon MBA was revolutionary. For A LOT of people the MBA is going to be their main computer for years to come for tasks a lot heavier than just "basic usage." It's not a cheap computer, and thus people expect it to perform well. For most users, it will still exceed their expectations, even while editing video and doing other "pro" workflows.Ĭlick to expand.I think this gets to the crux of the issue. I also believe Apple would have weighed all of this themselves when testing this machine and determining how it would perform for its expected user base. ![]() I think the effects of this throttling are far less than how it's being described. So far, I am not seeing any evidence that suggests that M2 MacBook Air users will have a poor experience. So, as is always the case with throttling, the debate is not "Does the machine throttle or not?", it's "How much of an impact does throttling have?" Pushing past that point will be even rarer still. And for users who manage to push to the throttling point, their performance only goes down to about the performance of M1. Even many sustained loads do not load up as much as Cinebench does. 7743.įor the vast majority of users, their workloads will stay well within the zone where they are reaping the benefits of M2's performance increase. So if you somehow have a workload that is pegging the CPU at 100%, or a combination of GPU + CPU that equals the same thermal output, for 15-20 minutes STRAIGHT, your performance STILL only drops to about the equivalent of M1's maximum performance. So if you look carefully, you see that after 10 consecutive runs, the M2 MBA has dropped about 1125 points.Ī drop of 1125 points puts it at about the same performance as M1's maximum performance, and this occurs after 15-20 minutes straight of 100% CPU load. I calculated that on his x axis, each interval represents 562.5 points. On top of that, I think Dave is over-estimating the impact of the throttling. But the majority of users who do video work who would buy this machine? No. At the highest end, sure, with very complex timelines with hefty codecs. You do also have the GPU cores to consider in that instance, but many renders for many users also would not take 15-20 minutes to complete. Even in a video editor, you rarely have a render that would peg the CPU to that degree, for that amount of time. If you've spent any time doing "Pro" workflows, and monitored your system usage, you would know that this amount of load, for that duration, is extremely rare. Remember, throttling is related to temperature over time, and the effects of it go up as your time under sustained load increases.Ĭinebench pegs the CPU at 99-100% utilization on all cores for the duration of the test. So 10 consecutive runs would take about 15-20 minutes. I calculated that a single run on the M2 would last anywhere from 1.5 to 2 minutes, based on its overall score. There are some important things to note here. ![]() This is Dave's graph of the effects of throttling on the Cinebench score, comparing the M2 MBA to the M2 MBP (which has a fan).
