I was trying to find anything specific about the iphone 12 gpu and i only found the same Apple 4 Core GPU.
I was not able to find any benchmark comparision either.
I found this, which is very unspecific:
"We didn't see as big a leap in graphics performance. On the 3DMark Wild Life test, the iPhone 12 hit 39 frames per second, while the iPhone 11 Pro Max scored an even higher 42 fps. But when we switched to the off-screen version of the test, the iPhone 12 Pro notched a higher 51 fps to the iPhone 11 Pro's 42 fps."
So if you don't have more details then i do, the basic assumption, you should make, is that its much easier to put much more silicon in a MBP than in a Smartphone and the chances, that a MBP is loosing against a Smartphone, would be very weird and very unrealistic.
And this has nothing to do with if someone likes apple or arm or whatever.
It is also not very easy to compare something like this if you don't know if there is a feature set difference and if one GPU can control 2-3 displays and the other only works for one display.
Simply by comparing my graphics demos running on my 13" MBP versus a recent iPhone or iPad Pro. The i-devices are usually slightly ahead (okay, my MBP is 5 years old by now, but progress has been slower on the Mac side than on the iPhone side).
It might not just be about fillrate though, I'm also seeing much higher drawcall throughput with Metal on iOS devices versus running Metal on Macs with Intel GPU. I guess the entire graphics stack is much better optimized on iOS.
Alone CPU is probably more then 100% : 4522 vs. 2091 and 2091 is the CPU value from the 2017 model because i was not able to find 2015.
Lets see how it looks
I don't care if its arm or x86 as long as the mac book finally fixes its performance/overheating issue when running a 4k display on it and as long as i can build and run x86 docker images.
Maybe the CPU part, but definitely not the integrated GPU (and this demo is all GPU).
