M3 iMac Design: Sleek, Stylish, and Built to Last

November 6, 2023

The M3 iMac Design hasn’t changed significantly. The machine still has a body that is only 11.5 millimetres thick, and it has a thin stand that lets you change the display’s orientation. The iMac is available from Apple in a variety of vivid hues, such as orange, yellow, purple, pink, green, blue, and silver. The iMac’s rear has significantly stronger and brighter colours than its front, which is decorated with softer, pastel colours. The iMac is powered via a magnetic power connection connected to a braided wire that matches in colour.

With a resolution of 4480 by 2520, 11.3 million pixels, 500 nits of brightness, P3 wide colour, over a billion colours, and True Tone to adjust the display’s colour temperature to the surrounding illumination for a more realistic viewing experience, this 24-inch 4.5K display has impressive specs.

M3 iMac Design AND DISPLAY

M3 iMac Design AND DISPLAY

The 2021 iMac debuted with a brand-new all-in-one desktop design featuring a sleek chassis and a rainbow of pastel hues. Its broad chin and fairly thick bezels surrounding the display, however, made it less than ideal. Regretfully, it appears that Apple intends to stick with this design. 

This new iMac is mostly focused on a new processor rather than making cosmetic changes. The screen is still a 24-inch, 500-nit brightness, 4.5K Retina panel. There are still four USB-C connectors (two of which are Thunderbolt ports), and the top 1080p FaceTime camera is still there. Additional connectors, such as an HDMI input/output and an SD card reader, would have been nice. 

Additionally, iMacs in green, yellow, orange, pink, purple, blue, and silver—along with peripherals that match in colour and Touch ID—feature the same vibrant colour scheme.

Apple debuted a redesigned 24-inch M3 iMac in October 2023, a revision to the vibrant desktop that debuted in 2021. The M1 chip has been replaced by an Apple-designed M3 Arm-based chip in the iMac, which offers notable performance and efficiency gains.

Based on a more sophisticated node, the M3 processor is Apple’s first 3-nanometer semiconductor. The M3 features an integrated GPU with up to 10 cores and an 8-core CPU with four high-efficiency and four high-performance cores. The 14-inch MacBook Pro is also equipped with an M3 chip.

With support for up to 24GB of unified memory, the iMac with an M3 processor outperforms the M1 iMac by up to two times. To speed up 3D modelling and provide more realistic lighting and shadows in video games, Apple introduced hardware-accelerated ray tracing and mesh shading. A 16-core neural engine and a media engine are also included.

Only Apple’s M3 processor, which provides significant performance gains over the previous generation’s M1 chip, is compatible with the iMac. The M3 chip features an 8-core CPU and an 8- or 10-core GPU, with the GPU having seen substantial enhancements.

Apple’s next-generation 3-nanometer architecture serves as the foundation for the M3 processor. With faster and more effective GPU technology, Apple claims that the M3 delivers the “biggest leap forward in graphics architecture ever for Apple silicon.” Dynamic caching, hardware-accelerated ray tracing, and mesh shading are all supported by the M3 GPU.

With dynamic caching, just the precise amount of memory required for each job is used by allocating the usage of local memory in hardware in real time. It improves the GPU’s average usage, which boosts performance for demanding professional apps and games.

Images may be produced that are more faithful to reality, as hardware-accelerated ray tracing makes the light appear more realistic as it interacts with a scene. Ray tracing and mesh shading are tools that game developers may employ to create more realistic shadows and reflections and to process geometry more quickly.

Apple claims that the M3 processor uses half the power and can provide 2.5 times faster GPU rates than the M1 chip.

Regarding the CPU, Apple claims to have enhanced the efficiency and performance of its core architecture. The M3 efficiency cores outperform the M1 efficiency cores by up to 50%, and the M3 performance cores outperform the M1 efficiency cores by up to 30%.

As claimed by Apple, the M3 processor in a MacBook Pro is 20% quicker than the M2, according to benchmarks. The M3 microprocessor achieved a multi-core score of around 11,700 and a single-core score of about 3,000. The M2 chip scores 2,600 on a single core and 9,700 on a multi-core.

Media Engine

Apple’s silicon processors come with a media engine that expedites video processing while minimising battery use. The M3 has hardware-accelerated support for H.264, HEVC, ProRes, and ProRes Raw in addition to specific acceleration for the ProRes video codec and video encode/decode engines.


Utilising a system-on-a-chip architecture, the M3 offers unparalleled power efficiency and unified memory. The M3 iMac delivers 100GB/s memory speed and can accommodate up to 24GB of unified memory, up from 16GB in the M1 iMac.


Apple has introduced the M3 iMac, a sleek, stylish, and built-to-last desktop machine that replaces the M1 chip in the iMac. The M3 chip, Apple’s first 3-nanometer chip, features an 8-core CPU with four high-efficiency cores and four high-performance cores, along with an integrated GPU with up to 10 cores. The iMac with an M3 chip is up to 2x faster than the M1 iMac, with support for up to 24GB of unified memory.

The M3 chip is built on Apple’s next-generation 3-nanometer architecture, delivering 2.5x better GPU speeds than the M1 chips while using half the power. The M3 performance cores are up to 30% faster than the M1 performance cores, and the M3 efficiency cores are up to 50% faster than the M1 efficiency cores. Benchmarks of the M3 chip in a MacBook Pro confirm that it is 20% faster than the M2 chip.

Apple includes a media engine in its silicon chips to speed up video processing while preserving battery life. The M3 offers dedicated acceleration for the ProRes video codec, video encode/decode engines, and hardware-accelerated support for H.264, HEVC, ProRes, and ProRes Raw. The M3 uses a system-on-a-chip architecture with unified memory and unmatched power efficiency, supporting up to 24GB of unified memory and 100 GB/s of memory bandwidth.


How long does the iMac last?

Three to eight years old
iMacs may survive anywhere from three to eight years, depending on the configuration. Larger hard discs are often included in iMac configurations as standard equipment. Generally speaking, a Mac Mini is more of an entry-level Mac, but it can be modified with larger hard drives, faster CPUs, and more RAM to last longer.

What is an iMac computer?

The main desktop computer made by Apple The iMac is an “all-in-one,” meaning that the monitor, drives, and computer are all housed in the same casing. Additionally, Apple produces a workstation and a compact desktop with separate displays (see Mac Mini and Mac Pro). The iMac Pro was once the top model of iMacs.

What is the latest iMac?

At its “Scary Fast” Mac presentation on October 30, which took place almost 30 months after the M1 model’s release, Apple unveiled the M3 iMac. Preorders for the new M3 iMac are already open, and delivery is scheduled for November 7. The next upgrade for the 24-inch iMac could not come out until 2026, assuming the same cycle.
