Why is there no comparison with Apple's iGPU?

nomercy400 2y ago
Because you cannot compare between an Apple's iGPU and this chip, while using the same software stack. Because you cannot buy a laptop with this chip and use MacOS. If they would compare it iwth an Apple iGPU, they'd be comparing two things: the hardware AND the OS, which makes it less clear what is contributing to your benckmark results.

  Generally this is a correct argument - to compare hardware one needs to use the same OS/software stack. But the argument works the other way around also, if there is no identical software stack possible does it really matter how raw hardware compares? The end user running a game or an application would experience hardware+OS rather than just hardware.

Apple Silicon hardware can run Linux (with unofficial GPU support as of late, although still lacking support for the NPU), and official support for Linux on Snapdragon laptop platforms is supposedly in the works. So we should be able to do a proper comparison as soon as official support is added for both platforms as part of a single mainline kernel release.

They would have to run the same software, e.g. install Linux on both machines.

If I had to bet, I would say it's because they don't beat Apple. If they had a benchmark result that showed a big win over Apple's design, it would be at the top row of the chart.

This is a hardware deepdive by a couple of uni students and enthusiasts... Some people are interested in things that aren't as shallow as fluctuating performance leads !

A lot of their testing is running custom OpenCL and Vulkan code, both of which are essentially unsupported on macOS (moltenvk exists, but kinda sucks and adds overhead that would make the comparisons invalid anyways).
