For example, even the fastest Intel-powered Mac might have experienced slowdowns and performance drops if a system process like iCloud, or the indexing of Photos or Spotlight, was running in the background. Having two types of cores ensures that background processes don’t slow down the computer because there is always enough power available for programs to run. Macs with Apple chips have two kinds of processor cores: high-performance and efficiency. There are other ways in which the M-series chips are more efficient than Intel processors. The 2019 Intel-powered 16-inch MacBook Pro could only manage 11 hours. The 16-inch MacBook Pro has the longest even battery life for a Mac at 22 hours. One advantage of ARM over Intel’s X86 is power consumption, this is evident in the long battery life of the M-series Macs. Many software developers were quick to update their software to run on M-series Macs, though. Apple addressed this with Rosetta 2, which translates the code from x86 to ARM and, with a few exceptions, there was no issue with software written for x86 running on the M1 Macs. Therefore one of the main concerns with the move to M1 (or any variant) could be whether the required software is compatible with ARM. ARM and x86 are completely different architectures-which means that they need different code, and hence the operating systems and software need to be tailored to them. The Apple Silicon is based on ARM, but includes a number of Apple technologies (so they aren’t ARM chips, strictly speaking). The Intel processors that Apple used in its Macs since 2006 were x86 chips. The M1-series Macs beat the equivalent Intel models. The M1 Ultra also offers twice the media engine capabilities of the M1 Max, for accelerated video encoding and decoding. The M1 Ultra can be configured with up to 128GB unified memory – according to Apple the most powerful PC graphics cards max out at 48GB. Apple also explained that the M1 Ultra behaves like, and is recognized by software, as one chip.Īt launch Apple claimed to offer “4x the bandwidth of the leading multi-chip interconnect technology” and that the m1 Ultra “delivers 90 percent higher multi-threaded performance than the fastest available 16-core PC desktop chip in the same power envelope.”Īpple also claimed that the 64-core GPU delivers faster performance than the highest-end PC GPU available – all while using 200 fewer watts of power. Apple achieves this using UltraFusion architecture to connect the two M1 Max chips to avoid trade-offs such as increased latency, reduced bandwidth, and increased power consumption. The M1 Ultra is essentially two M1 Mac chips, so it can offer a 20-core CPU and up to 64-core GPU. That’s more streams than on a 28-core Mac Pro with Afterburner.Īt launch, Apple stated that the performance of the M1 Max is “similar to that of the highest-end GPU in the largest PC laptops while using up to 100 watts less power.” Apple claimed the M1 Max powered MacBook Pros can edit up to 30 streams of 4K ProRes video or up to seven streams of 8K ProRes video in Final Cut Pro. M1 Max also has two ProRes accelerators that help it deliver up to 2x faster video encoding than M1 Pro. The M1 Max GPU goes all the way up to 32-cores (there is also a build-to-order 24-core option.)Īt launch, Apple claimed the graphics performance of the 32GB GPU to be up to 4x faster than the M1. The GPU is probably the most important difference between the M1 Pro and M1 Max. The M1 Max has the same 10-core CPU as the M1 Pro, but everything else is significantly enhanced.
