At Apple’s “Rapid Coming” conference today, Apple officially released the M3, M3 Pro, and M3 Max chips, which are the first PC chips using 3-nanometer process technology.
According to officials, the new generation of graphics processors equipped with the M3 series chips has achieved the largest leap in graphics processor architecture in the history of Apple chips. This graphics processor is not only faster and more energy-efficient, it also introduces a new technology – dynamic caching, and brings new rendering features such as hardware-accelerated ray tracing and mesh shading for the first time on Mac. Rendering speed is up to 2.5 times faster than M1 series chips. The CPU’s high-performance cores and energy-efficient cores are 30% and 50% faster than the corresponding cores in M1, respectively, and the neural network engine is 60% faster than those on M1 series chips.
M3 is equipped with an 8-core CPU, 10-core GPU, and 24GB of unified memory, and is up to 20% faster than M2; M3 Pro is equipped with a 12-core CPU, 18-core GPU, and 36GB of unified memory, and is up to 10% faster than M2 Pro; M3 Max is equipped with 16 Core CPU, 40-core GPU, 128GB unified memory, up to 20% faster than M2 Max.
According to Apple, the new generation of graphics processors in the M3 series of chips has achieved the largest graphics processor architectural leap in the history of Apple chips. Unlike traditional graphics processors, it has dynamic caching, so the use of local memory in the hardware can be allocated in real time. With the support of dynamic caching function, the memory consumption of each task accurately meets the needs. This industry-first technology is transparent to developers and provides the foundation for a new graphics processor architecture. It significantly improves the average utilization of the graphics processor, thereby significantly improving the performance of more demanding professional-level apps and games.
Powered by M3 series chips, hardware-accelerated ray tracing comes to Mac for the first time. Ray tracing technology simulates the behavior of light in a scene, helping apps create lifelike, realistic images. With the addition of this feature and the new graphics processor architecture, professional apps can run up to 2.5 times faster than M1 series chips. In addition, the new graphics processor also brings hardware-accelerated mesh shading to Mac, achieving a dual improvement in graphics processing capabilities and energy efficiency. It can also support games and apps that require high graphics processing to present scenes with more complex visual effects. According to officials, the M3 graphics processor can achieve performance comparable to M1 with half the power consumption, and can achieve up to 65% performance improvement at peak power consumption.
All chips in the M3 family feature Apple’s signature unified memory architecture. This results in high bandwidth, low latency, and unparalleled energy efficiency. In addition, the M3 chip supports memory capacities of up to 128GB, making possible workflows that were previously impossible to handle on a laptop, such as AI developers who can now run larger Transformer models with billions of parameters.
M3, M3 Pro and M3 Max chips also introduce an enhanced neural network engine for accelerating powerful machine learning (ML) models. The new neural network engine delivers up to 60% speed improvements compared to M1 series chips, further accelerating AI/ML workflows while keeping data on-device to protect user privacy.
It is noted that M3, M3 Pro and M3 Max also support multiple codecs, such as H.264, HEVC, ProRes and ProRes RAW, and AV1.
