Thanks to CTOnews.com netizen Jiayi for your clue delivery! CTOnews.com, October 31 (Xinhua)-- Apple officially released the M3, M3 Pro and M3 Max chips at Apple's "Fast coming" conference today, which is the first PC chip using 3nm technology.

The new generation of GPUs in the M3 series of chips has made the largest leap in GPU architecture in the history of Apple chips, officials said. The GPU is not only faster and more energy-efficient, but also introduces a new technology, dynamic caching, as well as new rendering features such as hardware-accelerated ray tracing and mesh shading that log into Mac for the first time. The rendering speed is up to 2.5 times faster than that of M1 series chips. The high-performance core and energy-efficient core of the CPU are 30% and 50% faster than the corresponding core of M1, respectively, and the neural network engine is 60% faster than that of M1 series chips.

M3 is equipped with 8-core CPU,10 core GPU,24GB unified memory, up to 20% faster than M2; M3 Pro is equipped with 12-core CPU,18 core GPU,36GB unified memory, 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 GPUs in the M3 series of chips has achieved the largest leap in GPU architecture in the history of Apple chips. Different from the traditional GPU, it has the function of dynamic cache, so it can allocate the use of local memory in hardware in real time. With the support of dynamic caching, the memory consumption of each task accurately meets the requirements. This industry-first technology is transparent to developers and provides the cornerstone for creating a new GPU architecture. It greatly increases the average utilization of GPUs, which in turn brings a significant improvement to the performance of more demanding professional-level App and games.

With the support of M3 series chips, the hardware accelerated ray tracing function is logged into Mac for the first time. Ray tracing technology can simulate the performance of light in the scene, thus helping App to create a lifelike, lifelike picture. With the addition of this function and the new GPU architecture, the professional App can run up to 2.5 times the speed of the M1 series chips. In addition, the new GPU also brings hardware-accelerated mesh shading to Mac, which not only improves graphics processing capacity and energy efficiency, but also supports games and App that require high graphics processing to render visually complex scenes. Officials say the M3 GPU can achieve the same performance as M1 when its power consumption is halved, and can achieve a performance improvement of up to 65% at peak power consumption.

All chips in the M3 family are equipped with the iconic unified memory architecture of Apple chips. This leads to high bandwidth, low latency, and unparalleled energy efficiency. In addition, the M3 chip supports up to 128GB memory, making it possible for workflows that could not be processed on laptops in the past, such as AI developers can now run larger Transformer models with billions of parameters.

M3, M3 Pro and M3 Max chips also introduce enhanced neural network engines to accelerate powerful machine learning (ML) models. Compared to the M1 series chips, the new neural network engine provides up to 60% speed gains, further accelerating AI / ML workflows while keeping data on the device to protect user privacy.

CTOnews.com notes that M3, M3 Pro, and M3 Max also support a variety of codecs, such as H.264, HEVC, ProRes and ProRes RAW, and AV1.
