If Apple really cared about their pro users they would have launched an Intel Mac Pro update to fill the gap but they didn’t because they don’t. Pros were ready to jump ship after the disastrous iMac Pro was launched in April of 2017 which is why Apple held a round table discussion with members of the press in April 2017 to allay those fears by promising that a new modular Mac Pro was coming. Two years later in December 2019 Apple fulfilled their promise by releasing the Mac Pro. But between 2017 and 2019 Nvidia made serious gains over the competition which left the Mac Pro obsolete on launch. Fast forward 3 years later to today and the pro market has really started to abandon Apple in favor of machines running Nvidia GPUs. Apple is attempting to create an updated Mac Pro that will bring those pros back to the platform and to do that they have to compete with Nvidia and to do that they have to ramp up the GPU core count significantly which has been difficult delaying the product further.
