When Alder Lake drops next month, the question goes away. Then answer is yes. > This was underlined sharply by an After Effects update that arrived in the middle of our testing, which enabled better multi-core acceleration. After Effects is still an Intel app, which runs in the Rosetta emulation mode on these machines, but the update allowed the app to light up all 10 CPU cores and all 32 GPU cores, cutting export times on our test from 4:29 to… 41 seconds. (It also substantially sped up performance on our Intel-based Mac Pro, which is nice.) From this point forward, all consumer processors have a GPGPU - either discrete or embedded on CPU package (AMD Zen has been this way since the beginning). Adapt or get supplanted by a new piece of software that takes advantage.

You may be better informed than I, but my understanding is that GPGPU would be like the integrated graphics found on AMD's Ryzen APUs based on the Zen architecture. But Zen is used in CPUs that do not have have integrated graphics. You specify "either discrete or embedded" but how is that different from before, i.e. "from this point forward"? Alder Lake CPUs also offer chips with our without integrated graphics, just as past Intel chips did. And, just as before, they are either paired with discrete graphics, or they have integrated graphics. None of that seems to answer the OP question, though. > Will Apple’s GPU ideas get fully supported by app developers? Since you're talking about Alder Lake, I'm guessing the change you're really trying to speak on is the pairing of performance and efficiency cores, which has been common in mobile devices for quite a long time, but was brought to laptops with Apple Silicon, and finally reaches desktops with Alder Lake.

  What is new is that the "integrated graphics" are programmable, like tiny little GeForce or Radeon chips. No, they aren't as powerful as discrete GPUs, but they can do a lot of work. If you want your software to stay competitive, you'd better start using it. Notice the quote - a software update to After Effects caused the execution time of some job they were doing to go from 4.5 minutes to 0.75 minutes. Same hardware. Same workload. The only difference was software that took advantage of this new hardware paradigm that is going to start showing up everywhere... > I'm guessing the change you're really trying to speak on is the pairing of performance and efficiency cores, which has been common in mobile devices for quite a long time, but was brought to laptops with Apple Silicon, and finally reaches desktops with Alder Lake. It is that, AND guaranteed access to a programmable GPU
