When rendering the main camera view, the 2021 14-inch MacBook Pro used on average about 7% of its battery charge, while the 2019 16-inch MacBook Pro used on average about 39% of its battery charge. When rendering the fern view, the 2021 14-inch MacBook Pro used on average about 19% of its battery charge, while the 2019 16-inch MacBook Pro used on average about 48% of its battery charge. Overall by every metric, the 2021 14-inch MacBook Pro achieves an astounding victory over the 2019 16-inch MacBook Pro: a little over twice the performance for a fraction of the total power consumption. The 2021 14-inch MacBook Pro also lives up to Apple’s claim of identical performance plugged in and on battery power, whereas in the results above, the 2019 16-inch MacBook Pro suffers anywhere between a 25% to 50% performance hit just from switching to battery power. The 2021 14-inch MacBook Pro’s performance win is even more astonishing when considering that the 2019 16-inch MacBook Pro is the previous flagship that the new M1 Pro/Max MacBook Pros are the direct successors to. Seeing this kind of jump in a single hardware generation is unheard of in modern tech and represents a massive win for both Apple and for the arm64 ISA. The M1 Max also handily beats the old dual Intel Xeon E5-2680 that I am currently using by a comfortable margin; for my personal workflow, this means that I can now do everything that I previously needed a large loud power-hungry workstation for on the 2021 14-inch MacBook Pro, and I can do everything faster on the 2021 14-inch MacBook Pro too.
The real surprises to me came with the 2019 Mac Pro and the Threadripper 3990X workstation. In both of those cases, I expected the M1 Max to lose, but the 2021 14-inch MacBook Pro came surprisingly close to the 2019 Mac Pro’s performance in terms of wall time. Even more importantly as a predictor of future scalability, the M1 Max’s efficiency as measured by core-seconds comes in at far far superior to both the Intel Xeon W-3245 and the AMD Threadripper 3990X. Imagining what a hypothetical future Apple Silicon iMac or Mac Pro with an even more scaled up M1 variant, or perhaps some kind of multi-M1 Max chiplet or multisocket solution, is extremely exciting! I think that with the upcoming Apple Silicon based large iMac and Mac Pro, Apple has a real shot at beating both Intel and AMD’s highest end CPUs to win the absolute workstation performance crown.
At least for my rendering use case, the Apple M1 Max is easily the most energy efficient processor, even without taking into account that the 60 W TDP of the M1 Max is for the entire system-on-a-chip including CPU, GPU, and more, while the TDPs for all of the other processors are just for a CPU and don’t take into account the rest of the system. The M1 Max manages to beat the 2019 16-inch MacBook Pro’s Intel Core i7-9750H in absolute performance by a factor of two whilst using anywhere between a two-thirds to half of the energy, and the M1 Max comes close to matching the 2019 Mac Pro’s absolute performance while using about a third of the energy. Of course the comparison with the Intel Xeon E5-2680 workstation isn’t exactly fair since the M1 Max is manufactured using a 5 nm process while the ancient Intel Xeon E5-2580s were manufactured on a 35 nm process a decade ago, but I think the comparison still underscores just how far processors have advanced over the past decade leading up to the M1 Max. The only processor that really comes near the M1 Max in terms of energy efficiency is the AMD Threadripper 3990X, which makes sense since the AMD Threadripper 3990X and the M1 Max are the closest cousins in this list in terms of manufacturing process; both are using leading-edge TSMC photolithography. However, on a whole, the M1 Max is still more efficient than the AMD Threadripper 3990X, and again, the AMD Threadripper 3990X TDP is for just a CPU, not an entire SoC! Assuming near-linear scaling, a hypothetical M1-derived variant that is scaled up 4.5 times to a 270 W TDP should be able to handily defeat the AMD Threadripper 3990X in absolute performance.
