nVidia seem to still only support OpenCL 1.1.
Presumably this is a conscious decision - they'd rather invest in CUDA.
I have no idea what AMD is up to regarding OpenCL. Have they just quietly dropped all support? [0][1]
Intel seem to be doing better, with support for OpenCL 2.1, with support for both CPU and GPU targets. [2]

This hasn't been true for quite some time now. They support 1.2.
The Radeon VII is also pretty fast in training transformer networks. In some models that I trained, it was only ~25% slower than our Quadro RTX 5000s.
As a Linux user, I’ll never buy a laptop with an Nvidia GPU again (if I can help it). What a pain.
A nice piece of hardware with relatively pathetic software to drive it.
Their Ubuntu-based distro, Pop!_OS, does a lot of good in this regard, and is really pretty plug and play for an Intel/NVIDIA combo set-up. The driver that they use to manage their CUDA install is also available for plain Ubuntu[1], and I've had good experience with using that to manage my own set-up running an Intel Xeon/NVIDIA P-series (if I'm remembering correctly). I haven't given it a shot on Debian, and if you're using something like Arch, there's a decent chance you'll be out of luck.
Note: I'm not affiliated with System76 in any way, just have slammed my head into this problem on multiple occasions and found this to be my go-to way of managing it.
They're still focused on their proprietary drivers, and naturally that means that they're way behind on supporting modern kernels. That's an issue if you have other hardware that only had support added recently. Their integration with X11's autoconfig also tends to have.. problems.
Nouveau basically doesn't work for their modern GPUs. My work laptop has a 1660Ti, and X11/Nouveau still can't render anything with it. Wayland/Gnome/Nouveau kinda sorta works, but I'd rather not have to use Wayland if I can avoid it.
Nvidia's support for PRIME is lacking. Their official stance was that you should restart your X11 session every time you wanted to swap. Bumblebee kind of worked, but was very slow and unstable. It looks like they finally implemented support for dynamic PRIME now, but of course they had to name their trigger environment variable something else, so that existing scripts for AMD PRIME wouldn't work.
Unless you want to do some cutting edge stuff with it. We're begging nVidia to fix their DPMS implementation over DisplayPort for years now.
Oh, I forgot that nVidia drivers do not make enabling VSync easy for video/compositing overlays for ~6 years? I have to disable all optimizations and lose 50% performance to enable VSync in a compositing or video layer.
Yes, most of it works but some annoying parts do not work, and nVidia doesn't make anything easier.
This is on a GTX680 card. It was king of the hill when I first bought it.
https://www.sisoftware.co.uk/2019/08/01/amd-vega2-gpgpu/ BW test over there shows 627GB/s of actual BW.
Nvidia's memory compression is very impressive and allows them to do better with a narrower memory bus in many situations (such as games), however if your data is not so compressible (often the case in GPGPU) this advantage disappears.
Really all I care about is a good OpenCL driver implementation, especially OpenCL 2.2 support would be extremely attractive.
