Why 4 USB A ports on newest desktops?

[Delacroix!]

I'm in the market for a new desktop as my current one is a bit aged, but why do the latest ones still have 4 usb A ports and only two USB c/Thunderbolt ports? The Macbook have 4 Thunderbolt 3 ports.

There are quite a bit of USB-A peripherals still in use. Thunderbolt 3 can be docked to extend the number of USB-C ports.

Awesome! Thx, for quick reply.

And I think the GPU in MacBook Pro 16 only has an x8 link to CPU, the additional Thunderbolt requiring more PCi-E lanes. But not sure.

the actual reason is the MBPs come with two Intel JHL7540 controllers (for 4 TB3 ports) and the iMac doesn't

Thanks, it just seems like the iMacs would have a couple more. Get rid of two USB A ports.

iMac still have x16 link to GPU. That’s why.
