The Base M6 CPU single core is averaging a bit over 4000 on Geekbench 7.
For comparison, the AMD Ryzen 9 9950X3D2 averages 3161 on the same test.

According to geekbench 7800x3d is 2400 single core, 15500 multicore. M4 pro is 3350 single core and 24750 multicore. Yet when I convert video using libsvtav1 with ffmpeg I’m getting noticeably faster performance on the desktop. And that’s with mbp, which doesn’t thermally throttle within 15 seconds.
Is it the 96mb cache? Avx-512? Are benchmarks bullshit when comparing different architectures?

Apple chips don't have AVX-512.
They do have media engines (that don't support AV1 encode), so if you switch to H.265, it will pull way ahead.

Zen 4 isn't 512 bits wide though, it's a split cycle 256 bit wide SIMD engine otherwise very similar (except in register size) to M6's.
The answer is more that Geekbench is at this point[1] heavily tuned to exactly the code Apple silicon does well: implicitly parallel wide-issue scalar code that you typically get out of modern compilers and JIT engines when throwing mostly-unoptimized "regular source code" at them. Apple has an enormous amount of instruction issue parallelism compared with x86.
The grandparent is looking at transcoding tasks where the limit isn't instruction issue but actual compute hardware on the core. And Apple doesn't actually win by much there.
It's just hard to know what to measure. Geekbench tends to be a metric for "feels fast doing boring interactive user stuff", which probably matches Apple's marketing imperatives well.
[1] Really they keep moving harder in that direction with every release. The "cooling pauses" in v6 likewise seemed very much like an attempt to boost the score on fanless Apple devices. If one were the type to allege a dark conspiracy, this is a tempting spot.

GB's author, John Poole, has stated the intent of Geekbench CPU is to measure the CPU and CPU alone, as in he doesn't want to measure limits caused by the form factor of the device the CPU under test is embedded in. Since GB runs on phones, that means he had to implement the cooldown pauses.
Intel's turbo boost means this GB feature almost certainly inflates lots of x86 scores too, even with fans involved. Not sure why you're being so conspiratorial about it.
