The M3's Unified Memory Architecture (UMA) is similar to the M2 generation; M3 SoCs use 6,400 MT/s LPDDR5 SDRAM. As with prior M series SoCs, this serves as both RAM and video RAM. The M3 has 8 memory controllers, the M3 Pro has 12 and the M3 Max has 32. Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14]
Apple M2 is a series of ARM-based system on a chip (SoC) designed by Apple Inc., launched 2022 to 2023.It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, the iPad Pro and iPad Air tablets, and the Vision Pro mixed reality headset.
A MacBook Air (15-inch, M2, 2023) running macOS Ventura. On June 6, 2022, during the 2022 Worldwide Developers Conference (WWDC), Apple announced their second-generation processor, called M2, with an improved performance versus the previous M1 processor. The first computer to receive this new chip was a radically redesigned MacBook Air.
Apple announced the M3 series of chips on October 30, 2023, along with the new MacBook Pro and iMac, and later used in the MacBook Air. The M3 is based on the 3 nm process and contains 25 billion transistors, a 25% increase from the previous generation M2. It has 8 CPU cores (4 performance and 4 efficiency) and up to 10 GPU cores.
In March 2024, the MacBook Air was also updated to include the M3 chip. [153] In October 2024, several Macs were announced with the M4 series of chips, including the iMac, a redesigned Mac Mini, and the MacBook Pro; all of which included 16 GB of memory as standard. The MacBook Air was also upgraded with 16 GB for the same price. [154]
Apple M1 is a series of ARM-based system-on-a-chip (SoC) designed by Apple Inc., launched 2020 to 2022.It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, and the iPad Pro and iPad Air tablets. [4]
The M4 Pro features an up to 14-core CPU, with 10 performance cores and 4 efficiency cores, along with up to a 20-core GPU that Apple claims is twice as powerful as that in the M4 when used in the corresponding MacBook Pro. The M4 Pro is available with up to 64GB unified memory (Mac Mini) with a theoretical maximum bandwidth of 273GB/sec. [11]
This launched alongside an updated MacBook Air, with a new design, and also with the M2 chip. The specifications of the M2 MacBook Pro are almost the same, but it supports up to 24 GB of unified memory. The 13-inch Touch Bar MacBook Pro was discontinued on October 30, 2023, in favor of an entry-level 14-inch model with the base M3 chip and two ...
