the OS running on the chip makes a HUGE difference to perceived performance (compare a Linux setup to a Windows 10 one on similar hardware and you'll see what I mean)
So assume that the desktop PC runs Linux, when it e.g. compiles a million lines of code or converts from one video format to another, or generates an animation movie from a script, or ... Android is Linux based, so even though a number of adaptations to smartphone hardware has been made, this shouldn't affect pure CPU / GPU performance that much.

Obviously there are lots of different Intel/AMD desktop chips and GPU chips, and there are lots of Snapdragon models. That should not make it impossible to say that an Intel-so-and-so at X GHz running FFmpeg will convert MPEG2 to H.264 x times faster than a Snapdragon-so-and-so at Y GHz, also running MMmpeg! (FFmpeg is available for ARM, I guess that also includes Snapdragon.)

Similarly obvious: Smartphone CPUs/GPUs are specialized to the assumed needs. But a Snapdragon is Turing complete, so in principle it can do anything that a desktop PC can do. The reason why I ask for relative performance under various workloads is to learn what kind of tasks fit into the smartphones' intended application area (that is, good performance) and which is outside (that is, poor performance, compared to the desktop PC).

I have several friends who went from desktop PCs to portable PCs to smartphones - they haven't owned a desktop machine for eight years, not a portable for three. They do all their tasks on their phone, even video editing. (Don't ask for my comments on the result of that video editing, though...) Portable PCs have essentially been almost as closed, fully controlled hardware environments as the smartphones (today, you connect the same crowd of USB devices to smartphones as you do to portables). We still can compare performance with desktop PCs. Smartphones gradually take over a far more varied set of tasks, software-wise becoming more and more similar to PCs. Today, the fruit salad is a mix of apples and oranges.

Five years ago we could evade the question of relative performance by pointing out differences in tasks and environment. Today, getting to know hard performance factors is highly relevant. If there isn't any availabel, it ie about time that someone start doing it.
