The iMac Pro was designed to handle 500W (the display uses some power too). The Vega 64 GPU is 250-300W, the CPU is 140W. The only option to keep the Mac Pro at all is to redesign it, even beyond the cheese-grater because the power limits in the cheese grater were similar to the iMac Pro and cylinder. They managed to increase the thermal capacity of the iMac by 80%, which makes the cylinder redundant.


They typically don't sell multiple computers with the same spec in the same category. They just have no way to make it faster than the iMac Pro in order to justify it remaining in the lineup.

This makes me wonder why Apple are replacing the cylinder form factor due to “thermal issues.” It doesn’t seem to have thermal issues.
