The M1 Pro has 256-bit LPDDR5 SDRAM, and the M1 Max has 512-bit LPDDR5 SDRAM memory. While the M1 SoC has 70 GB/s memory bandwidth, the M1 Pro has 200 GB/s bandwidth and the M1 Max has 400 GB/s bandwidth. [8] The M1 Pro comes in memory configurations of 16 GB and 32 GB, and the M1 Max comes in configurations of 32 GB and 64 GB. [17]
The Mac Studio is designed as a higher-grade machine than the Mac Mini but lower than the Mac Pro, and is positioned similarly to the now-discontinued iMac Pro. [ 5 ] [ 6 ] There are two models which are driven by ARM-based SoC : the M1 Max or the M1 Ultra , which combines two M1 Max chips [ 7 ] in one package. [ 8 ]
The M1 Pro and M1 Max have a 16-core and 32-core GPU, and a 256-bit and 512-bit LPDDR5 memory bus supporting 200 and 400 GB/s bandwidth respectively. [20] Both chips were first introduced in the MacBook Pro in October 2021. [21] The M1 Ultra is a processor combining two M1 Max chips in one package. [22]
According to Apple, the Mac Studio with an M1 Max is 2.5 times faster than the company's fastest Intel-powered 27-inch iMac and 50% faster than the Mac Pro with a 16-core Intel Xeon processor.
MacBook Air (M1, 2020) On November 10, 2020, Apple announced an updated MacBook Air with an Apple-designed M1 system-on-a-chip (SoC), launched alongside an updated Mac Mini and 13-inch MacBook Pro as the first Macs with Apple's new line of custom ARM-based Apple silicon processors. [6]
The pointer sections are 32-bit (4-byte) address values for 32-bit Mach-O binaries and 64-bit (8-byte) address values for 64-bit Mach-O binaries. Pointers are read by machine code and the read value is used as the location to call the method/function rather than containing machine code instructions.
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.
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]
