1 Compared to a powerful discrete GPU for PC notebooks, M1 Pro delivers more performance while using up to 70 percent less power. M1 Pro has an up-to-16-core GPU that is up to 2x faster than M1 and up to 7x faster than the integrated graphics on the latest 8-core PC laptop chip. 1 Even the most demanding tasks, like high-resolution photo editing, are handled with ease by M1 Pro. Compared with the latest 8-core PC laptop chip, M1 Pro delivers up to 1.7x more CPU performance at the same power level and achieves the PC chip’s peak performance using up to 70 percent less power. A new 10-core CPU, including eight high-performance cores and two high-efficiency cores, is up to 70 percent faster than M1, resulting in unbelievable pro CPU performance. Utilizing the industry-leading 5-nanometer process technology, M1 Pro packs in 33.7 billion transistors, more than 2x the amount in M1. M1 Pro: A Whole New Level of Performance and Capability “With massive gains in CPU and GPU performance, up to six times the memory bandwidth, a new media engine with ProRes accelerators, and other advanced technologies, M1 Pro and M1 Max take Apple silicon even further, and are unlike anything else in a pro notebook.” No one has ever applied a system-on-a-chip design to a pro system until today with M1 Pro and M1 Max,” said Johny Srouji, Apple’s senior vice president of Hardware Technologies. “M1 has transformed our most popular systems with incredible performance, custom technologies, and industry-leading power efficiency. The GPU in M1 Pro is up to 2x faster than M1, while M1 Max is up to an astonishing 4x faster than M1, allowing pro users to fly through the most demanding graphics workflows. The CPU in M1 Pro and M1 Max delivers up to 70 percent faster CPU performance than M1, so tasks like compiling projects in Xcode are faster than ever. Scaling up M1’s transformational architecture, M1 Pro offers amazing performance with industry-leading power efficiency, while M1 Max takes these capabilities to new heights. Powering the all-new MacBook Pro, new chips feature up to a 10-core CPU, 32-core GPU, 64GB of unified memory, ProRes acceleration, and industry-leading power efficiencyĬUPERTINO, CALIFORNIA Apple today announced M1 Pro and M1 Max, the next breakthrough chips for the Mac. Introducing M1 Pro and M1 Max: the most powerful chips Apple has ever built M1 Pro and M1 Max are by far the most powerful chips Apple has ever built. M1 Pro and M1 Max also feature enhanced media engines with dedicated ProRes accelerators specifically for pro video processing. The efficient architecture of M1 Pro and M1 Max means they deliver the same level of performance whether MacBook Pro is plugged in or using the battery. And while the latest PC laptops top out at 16GB of graphics memory, having this huge amount of memory enables graphics-intensive workflows previously unimaginable on a notebook. M1 Max delivers up to 400GB/s of memory bandwidth - 2x that of M1 Pro and nearly 6x that of M1 - and support for up to 64GB of unified memory. M1 Pro offers up to 200GB/s of memory bandwidth with support for up to 32GB of unified memory. The chips feature fast unified memory, industry-leading performance per watt, and incredible power efficiency, along with increased memory bandwidth and capacity. For example, to determine if AVX512 vector instructions are available, use the sysctlbyname function to check the hw.optional.avx512f attribute.M1 Pro and M1 Max introduce a system-on-a-chip (SoC) architecture to pro systems for the first time. If you include these newer instructions in your code, execute them only after verifying that they are available. Rosetta translates all x86_64 instructions, but it doesn’t support the execution of some newer instruction sets and processor features, such as AVX, AVX2, and AVX512 vector instructions. Virtual Machine apps that virtualize x86_64 computer platforms However, Rosetta doesn’t translate the following executables: Rosetta can translate most Intel-based apps, including apps that contain just-in-time (JIT) compilers. Note specifically this (does Calibre use Kernel extensions?): Here's a link from Apple that describes what is compatible: In the past calibre has had dual ppc/x86 builds for os x, so its not impossible, just dont expect it to be anytime soon. Cant answer your first question, as to the second, pretty hard, all of calibre's deps would need to be dual compiled.
