Apple Silicon M1 chip in MacBook Air outperforms high-end 16-inch MacBook Pro

Can somebody explain how is M1 going to work on larger GPU tasks (rendering, encoding etc) with it's memory bandwidth M1 total memory bandwidth is 68.2 GB/s (128 bit LPDDR4x-4267)

AMD Radeon Pro 5600m memory bandwidth is 394.2 GB/s (2048 bit HBM2)

It's not clear, but here's some knowledgeable speculation:

- All M1 models only have 1 Thunderbolt Controller, thus can only handle 2 Thunderbolt ports on all announced models so far.

- All M1 models only support 1 monitor, but up to 6K.

- No M1 model supports >16GB of RAM or 10GB Ethernet.

All of the above seem like bandwidth limitations to save cost that a future "M1X" or "M2" or "X1" would be extremely likely to fix, and that's where you'll see the bandwidth increase.

> - All M1 models only support 1 monitor, but up to 6K.

Where did you find this? In the Macbook Pro 13 landing page I find the specs per Thunderbolt port which states the display capabilities for each while not restricting anywhere to just one monitor.

So I'd would expect 1x monitor per Thunderbolt port leading to total 3 displays for the Pro ARM model: one internal and two external displays. I assume the restriction you refer to just applies to the Air model.

In the tech specs page, under "Video Support":

> Simultaneously supports full native resolution on the built-in display at millions of colors and:

>

> One external display with up to 6K resolution at 60Hz
