The Nvidia/Apple relationship has been crumbling for nearly a decade
There was even a bit of confusion when Apple announced the latest Mac Pro, as it eschewed super powerful Nvidia GPUs with
hardware-accelerated ray tracing support to embrace AMD’s hardware.
But look, the Nvidia/Apple relationship has been crumbling for nearly a decade. A little more than ten years ago
Apple and Nvidia lost a whole lot of money due to a series of failed GPUs in the MacBook Pro line up. It went so poorly that
Apple started to rely on AMD for its GPUs despite Nvidia’s popularity and typically better performance. That’s why Apple’s MacBook Pro line up kept using less powerful AMD GPUs when Nvidia’s robust and popular series of mobile processors were sitting right there.
But despite the reliance on AMD hardware Apple continued to support Nvidia GPUs. If you wanted to cram a Nvidia card into your older Mac Pro or rely on it for your hackintosh then Apple and Nvidia had you covered. Until last year when
Apple quietly stopped support CUDA with the release of macOS 10.14 Mojave. That forced apps that relied on CUDA for hardware acceleration, like Adobe’s suite of software, to
issue warnings and reminders to customers.
Nvidia ending support after CUDA 10.2 is really more tit for tat than any kind of major statement. Yet it does leave some people, like the aforementioned hackintosh users, in the lurch. It also means that it’s now going to make Apple devices a lot less appealing to some high-end developers and animation professionals. Currently, Nvidia is the only company making GPU hardware capable of hardware-accelerated ray tracing, a welcome tool used by animators and developers.
