There are two Thunderbolt 3/USB-4 ports at the back of the iMac, along with four total USB-C ports for some models. The iMac also offers studio-quality microphones and a six-speaker sound system with strong bass and clear mids and highs, along with support for Dolby Atmos and spatial audio. The 24-inch 4.5K display features a resolution of 4480-by-2520, with 11.3 million pixels, 500 nits brightness, P3 wide color, more than a billion colors, and True Tone to match the color temperature of the display to the ambient lighting for a more natural viewing experience.Īpple's M1 iMac includes a 1080p FaceTime HD camera with a new image signal processor for improved performance in low light, and the Neural Engine in the M1 chip allows for better noise reduction, greater dynamic range, and improved auto exposure and white balance. Powering the iMac is a new magnetic power connector with a color-matched woven cable. At the front of the iMac, there are softer, pastel colors, but the back of the iMac features much brighter and bolder colors. The iMac comes with a redesigned slim stand that allows the angle of the display to be adjusted.Īpple is selling the new iMac in a range of bright colors, including green, blue, pink, silver, orange, yellow, and purple. The design is extremely thin and compact compared to prior models, and the machine measures in at just 11.5 millimeters thick. There are major external design changes with the M1 iMac. It is also considerably quieter than the previous version thanks to the thermals of the M1 chip and the new cooling system. The logic board and thermals have been dramatically consolidated and reduced in size, so the new iMac takes up less space and fits more easily in different places. The M1 chip enables the thinner design introduced with the new iMac. As with the prior entry-level 21.5-inch iMac models, RAM maxes out at 16GB. The M1 has an 8-core CPU with four high-efficiency cores and four high-performance cores along with an integrated GPU that has up to 8 cores, and it is the same M1 chip that was first used in the MacBook Air, MacBook Pro, and Mac mini.Īccording to Apple, compared to the previous generation 21.5-inch model, the M1 iMac offers up to 85 faster CPU performance, up to 2x faster GPU performance, and up to 3x faster machine learning. The M1 chip is Apple's first System on a Chip for the Mac, integrating the CPU, GPU, RAM, and more. ![]() The iMac now features an Apple-designed "M1" Arm-based chip, replacing the prior Intel chips, to bring significant speed and efficiency improvements. The PowerPC 604e was the first Mac processor available in a symmetric multiprocessing (SMP) configuration.Apple unveiled the new 24-inch M1 iMac in April 2021, a radically redesigned desktop machine that comes in a range of fun colors. The PowerPC 601 was the first Mac processor to support the 32-bit PowerPC instruction set architecture.Ī Motorola PowerPC 603 processor Processor The MC68LC040 version was less expensive because it omitted the floating-point unit. The Motorola 68040 had improved per-clock performance compared to the 68030, as well as larger instruction and data caches, and was the first Mac processor with an integrated floating-point unit. Another improvement over the 68020 was the addition of a data cache. ![]() The Motorola 68030 was the first Mac processor with an integrated memory management unit, allowing for virtual memory. It had 32-bit CPU registers, a 24-bit address bus, and a 16-bit data path Motorola referred to it as a "16-/32-bit microprocessor." Processor The Motorola 68000 was the first Apple Macintosh processor. A Motorola 68000 processor in a dual in-line package, as the early Macintosh models used
