What does this mean?
The price Apple charged in the US on launch day for the lowest configuration, before tax.
This is not what the Mac costs today. More memory, storage or a faster chip cost extra. Older models drop in price over time, so check the used and refurbished links for current prices.

Chip
Apple M2 Ultra›Apple M3 Ultra
What does this mean?
Ultra is the largest Apple silicon chip in a generation, with up to twice the CPU and GPU cores of the Max chip from the same generation. For M1, M2 and M3 Ultra, Apple says it connects two Max chips with a link it calls UltraFusion.
Apple uses Ultra chips only in Mac Studio and Mac Pro. The extra cores help most with work that can use all of them at once, such as video exports, 3D rendering and machine learning.
Matters most if: You edit high-resolution video or work with very large 3D or machine learning projects.
CPU cores
24›28
What does this mean?
The CPU is the part of the chip that runs your apps. More cores means it can work on more things at the same time.
More cores help most when exporting video, compiling code or running many apps at once. For browsing and email, the difference is small. Cores are only comparable within the same family: one Apple silicon core and one Intel core do not do the same amount of work.
Memory (base)
64 GB›96 GB
What does this mean?
How much memory (RAM) the cheapest configuration comes with, in gigabytes (GB).
More memory lets you keep more apps and browser tabs open without slowing down. 8 GB is enough for browsing and documents; 16 GB or more helps with photo editing, video and many apps at once. On Apple silicon Macs memory cannot be added later.
Matters most if: You keep many apps or tabs open, or edit photos and video.
Memory (most you can order)
192 GB›256 GB
What does this mean?
The most memory you could order from Apple for this model.
Only matters if you plan to buy a high-end configuration, for example for large video projects or software development.
Storage (most you can order)
8 TB›16 TB
What does this mean?
The most storage you could order from Apple for this model.
Only matters if you need to keep very large files on the Mac itself rather than on an external drive.
GPU cores
60 (same on both)
What does this mean?
The GPU handles graphics: what you see on screen, games, and video and photo effects. Apple lists GPU cores for its own chips.
More GPU cores make games, 3D work and video editing smoother. "Not published by Apple" means the Mac uses Intel or AMD graphics, which Apple does not describe in cores.
Neural Engine cores
32 (same on both)
What does this mean?
The Neural Engine is a part of Apple silicon built for machine learning tasks, such as recognizing faces and text in photos.
It speeds up features like Live Text, photo search, voice dictation and Apple Intelligence, while using little battery. Intel Macs do not have one.
Memory type
Unified memory (same on both)
What does this mean?
Memory (RAM) is the working space for open apps and files. Apple silicon uses unified memory: one pool shared by the CPU, GPU and Neural Engine. Intel Macs list a memory type such as DDR4.
Unified memory is part of the chip, so it cannot be added later. Apple's spec pages list user-accessible memory slots only for the 27-inch Intel iMac and the 2019 Mac Pro.
Storage (base)
1 TB (same on both)
What does this mean?
Storage is where your files, photos and apps are kept. This is the amount in the cheapest configuration. 1 TB (terabyte) is 1,024 GB. Some older iMacs came with a hard drive or Fusion Drive instead of an SSD; the notes say when.
A desktop Mac can keep an external drive plugged in all the time, which makes a smaller internal drive easier to live with. Photo libraries and video fill storage fastest.
Ports & charging1 gain · 3 changes
USB-C ports
6x Thunderbolt 4 (USB-C)›6x Thunderbolt 5 (USB-C)
What does this mean?
The sockets on the Mac, front and back together. Each row shows one port gained or lost. Ethernet has its own row.
Built-in HDMI and an SD card slot mean fewer adapters when you connect a TV or projector or copy photos from a camera. With fewer ports you rely more on USB-C hubs and adapters.
Matters most if: You connect displays, cameras or many accessories.
Front: USB-C ports
2x Thunderbolt 4 (USB-C)›2x Thunderbolt 5 (USB-C)
What does this mean?
The ports on the front of the Mac, which you can reach without turning it around. They are also counted in Ports.
Handy for things you plug in and out often, such as headphones, a USB stick or an SD card from a camera. "Not listed separately by Apple" means Apple's spec page lists the ports without saying which are on the front.
Thunderbolt version
Thunderbolt 4›Thunderbolt 5
What does this mean?
Thunderbolt is a fast connection that uses the USB-C plug (Thunderbolt 2 used an older, smaller plug). Gb/s is gigabits per second. Thunderbolt 2 goes up to 20 Gb/s, Thunderbolt 3 and 4 up to 40 Gb/s, and Thunderbolt 5 up to 120 Gb/s.
Faster Thunderbolt matters for external SSDs, docks and high-resolution displays. For charging, keyboards and mice, every version works the same.
Maximum continuous power
370 W›480 W
Ports on both
2x USB-A (up to 5Gb/s), HDMI, SDXC card slot, 3.5 mm headphone jack (same on both)
Front ports on both
SDXC card slot (same on both)
Ethernet
10Gb Ethernet (same on both)
What does this mean?
Ethernet is a wired network connection: a cable from the Mac to your router. Gigabit Ethernet carries up to 1 Gb/s (gigabit per second), 2.5Gb Ethernet up to 2.5 Gb/s and 10Gb Ethernet up to 10 Gb/s. "10Gb option" means Apple sold a 10Gb port as an option when you ordered; "optional" means Ethernet itself was an option.
A cable is steadier than Wi-Fi for video calls and large downloads. The faster speeds only help if your router, switch or network drive is just as fast.
Matters most if: You copy large files to and from a network drive or other computers.
External displays (most)
8 external displays (same on both)
What does this mean?
The most separate displays you can connect at the same time, as Apple's spec page lists it. On an iMac this is on top of its own screen.
Very high resolutions or refresh rates can lower the number; Apple's spec page lists the exact combinations. More display support helps when you spread your work across several screens.
Matters most if: You want two or more monitors on your desk.
Wi-Fi
Wi-Fi 6E (same on both)
What does this mean?
Wi-Fi generations. Each new one handles more devices at once and higher speeds: Wi-Fi 5 (2014), Wi-Fi 6 (2019), Wi-Fi 6E adds a new, less crowded radio band, Wi-Fi 7 is the newest.
You only get the extra speed if your router supports the same generation. With an older router, the difference is small.
Bluetooth
Bluetooth 5.3 (same on both)
What does this mean?
Bluetooth connects wireless headphones, mice, keyboards and game controllers. Newer versions have more range and use less power.
Most accessories work with any of these versions. Newer versions mainly help with range and connection stability.
Design1 change
Weight
3.6 kg›3.64 kg
What does this mean?
Weight in kilograms. 1 kg is about 2.2 pounds.
For a desktop Mac, weight matters when you move it or take it between places.
Height
9.5 cm (same on both)
Width
19.7 cm (same on both)
Depth
19.7 cm (same on both)
Speakers
Built-in speaker (same on both)
What does this mean?
How Apple describes the Mac's speakers on its spec page. Apple's wording varies between models. We show it exactly as Apple lists it.
Apple lists a single built-in speaker for Mac mini, Mac Studio and Mac Pro, so for music and films you will want speakers or headphones. Systems with force-cancelling woofers give fuller sound with more bass.
