Is it really true this A12X is comparable to last year's Macbook Pro?

On that Macbook Pro I could run several VMWare sessions running Windows and Linux (have run 3 at the same time in the past). I can run Handbrake encoding videos across cores while still browsing the net in Chrome with 4 windows open each to different profiles each with 5 to 20 tabs. Have 4 terminal windows open, at list one of them serving a dev webpage. Run VSCode and Unity and Visual Studio and other stuff all at once. I've also done things like compile Chrome from source. Run XCode, run 2-3 iOS simulators.

I get that an A12X can't do those exact tasks as it's not the same instruction set but could it do the equivalent and get similar perf?

That's amazing if true. An iPad Pro weighs 1/4th of my MBP (2014). My MBP's fans spin like crazy when running a high intensity app and the case gets too hot to touch.

I'd love to believe a machine that has no fans and doesn't get hot and weighs 1/4 as much could actually have the same or more perf for real but when I actually use an iPad it rarely feels as fast and given it doesn't multitask well there's no way for me to check that perf is really comparable in real world use cases.

Anyone have any insight? Is it just because the chip was redesigned to be more efficient it can match or exceed the i7 in my MBP? Should Amazon be filling their AWS racks with A12X based machines that get the same per at much less heat and power? (Yea I know they can't by A12X chips buy still). Don't iPhones and say top Samsung phones generally show similar perf?

It is comparable at running geekbench 4, yes. And some web benchmarks seem pretty comparable.

But your workload doesn't seem to include those things, so hard to say. Critically A12X is unlikely to have hardware virtualization support, so your use case of VMware would be slow even if it wasn't doing any binary translation.

Also your MBP's fans spin because it's trying to achieve higher sustained performance. Typically mobile devices will just instead thermal throttle hard. Like, lose half their performance hard. How well can the iPad Pro sustain its performance? That's a real big question.

Re AWS racks: No, they can't. A12X in the server world would be a joke. It'd be competing against things like AMD's Rome which is 64 cores / 128 threads with, and this part is critical, up to 4TB of RAM with 128 PCI-E lanes. Even if the A12X could compete on raw CPU throughput it can't compete on I/O, virtualization, etc... The A12X is also going to be pulling a lot more power than you might expect. It's not that much more power efficient.
