Same Hardware Different Price

I'm in the market for a new Macbook. I probably won't be buying either brand new, but after playing around with the options, I noticed that upgrading the 16-inch Macbook Pro with different options can lead to the same outcome with different prices:

Here are the steps:

On the buy new page, click through to the 2.6GHz 6-core option, upgrade to the 2.4 GHz, 8-core option for $300, then upgrade to the 1TB SSD option for $200.

You will end up with a computer that costs $2,899.

On the buy new page, click through to the 2.3GHz 8-core option, upgrade to the 2.4 GHz, 8-core option for $200. Total is $2,999. RAM, graphics, and SSD space are the same (if you upgraded to 1TB in the previous example).

I know that someone who picked the 2.3GHz 8-core option is unlikely to upgrade to the 2.4 GHz 8-core option for an additional $200, but it begs the question: are there more differences between these computers? RAM and graphics are the same, but maybe there is something unseen?
