The announcement of the transition to Apple Silicon chips has left most Mac users excited, but there are doubts around more professional users who require maximum performance. Are you sure ARM chips will have the graphics power of the most powerful desktops?
We may have an interesting lead on that today. In the documentation of one of the sessions given to developers during WWDC20, it was made clear that Macs with Apple Silicon chips will have their own GPUs . That is, there will be no integrated graphics cards from Intel, or discrete cards from AMD or NVIDIA.
Until now, cheaper Macs with less graphics performance have typically used integrated Intel graphics cards. And for the more powerful Macs, one or more discrete cards from AMD or NVIDIA are used. The future, as we’ve seen it, is unified: Apple’s own GPUs in every machine.
The consequence is that macOS would abandon support for these third-party graphics cards as soon as the transition to Apple Silicon is complete, which in turn means that external eGPUs will no longer be compatible with Macs . It is not certain, we cannot confirm this at all, but it is suspected at this time.
At AppleThe dilemma of the Mac with Apple Silicon: buy a computer now or wait for the first ARM
I think there’s reason to be optimistic. Of course, the first Macs with Apple Silicon aren’t going to have more graphics power than a Mac Pro, but the first benchmarks of the Developer Transition Kit (that Mac mini with an A12Z chip) promise even running under an emulation layer. And I also remember that that Mac mini was used in the demonstrations of the keynote of the WWDC20 connected to an XDR Pro Display. And unless they purposely lowered the resolution, it means that an A12Z chip can handle a 6K display. This is no joke.
Apple’s documentation is also clear: ” Don’t assume that a discrete GPU means more performance “ , we can read about it. “The GPUs built into Apple processors are optimized for high-performance graphics tasks. Sounds like the Macs we’ll see in a few months will surprise us.
