Higher-End iMac's Ports Are All Thunderbolt 4

by

Apple today released new iMac models, and while there are few external changes with the exception of some color tweaks, Apple made several internal updates to the machine. The inclusion of the next-generation M4 chip is the biggest update, but the ports have also seen improvement.

For the M4 ‌iMac‌ models with 10-core CPU and 10-core GPU, all four of the USB-C ports support Thunderbolt 4 transfer speeds of up to 40Gb/s. The prior-generation M3 ‌iMac‌ with four ports had two Thunderbolt 3 ports and two USB-3 ports.

The 8-core CPU and 8-core GPU models only have two ports, but both of those are Thunderbolt 4. All of the USB-C/Thunderbolt 4 ports also support USB 4 and USB 3.1 Gen 2.

Pricing on the ‌iMac‌ starts at $1,299 for the 8-core CPU/GPU version, while the 10-core CPU/GPU models with four ports are priced starting at $1,499. Apple is accepting pre-orders for the new M4 ‌iMac‌ models as of today.

Are all 4 Thunderbolt 4 Ports on the 10 Core M4 iMac model sharing any Thunderbolt channels, or do each of the Thunderbolt 4 ports have its own (non-shared, full speed) Thunderbolt 4 data channel for the full speed data transfer that Thunderbolt 4 allows (40 Gbps)?

Also when do you think we will see full speed (80 Gbps) Thunderbolt 5 port support on Mac models (M5, M6, or M7)?

slightly off-topic to the iMac announcement itself, but are we expecting one new mac per day? something else later today?

they said "starting monday morning" but no further information about announcement timing

I assume it still can't be used as an external display?

I've noticed at the end of the keynote, Ternus said: Join us tomorrow morning for another exciting announcement

@jclo

The 8-core models don’t have Thunderbolt 4 ports. They have Thunderbolt / USB 4 ports that support Thunderbolt 4.

Thunderbolt 4 certification requires support for two external displays.
