Can only comment about Nvidia hardware as no experience with AMD gpus.
Maybe someone with direct AMD gpu knowledge with the FGRPB1G tasks will comment.
Here with two tasks running concurrently I am using a smidge over 2GB of gpu memory.
So right at 1GB for a task I presume.
Think it would be tight with just a 1GB card.
Your guess of the Radeon R7 250 2GB model would probably fit your needs. Enough memory, FP64 support, low-profile and pulls power only from the PCIE slot. Here is a 240 for example.
The recent shortage on FGRPB1G tasks got me thinking: what other application(s) could I run on my GPU (AMD Radeon R7 240 from ~2013) ?
So far I had only luck with FGRPB1G tasks. I had a quick go with BRP7 but it didn't work out in the end (I'm using Mesa OpenCL 1.1, that could explain why).
OpenCL 1.2 got merged in Mesa back in 2020, but I couldn't get it to work:
Mesa OpenCL is generally regarded as unworkable in BOINC. Using the standard manufacturer sourced driver versions of OpenCL is expected and works the best.

If you haven't acquired one yet, I would get a 2GB version. Plus, in Einstein, GPUs don't take up any bandwidth to speak of (at least for mine).

Dear all,
@GWGEORGE007: I'm unable to find any 2GB model at the moment. If I were to buy a GPU with only 1GB of RAM, would FGRPB1G still work ?
Another option would be to buy a Radeon R7 240, which comes in either 2 or 4GB models:

I would definitely stay away from the 1GB GPU, whatever model. You could go for a 2GB, and 4GB would be better yet providing you can afford it.
My suggestion would be to follow Keith's advice. I also have no experience with AMD GPUs.

Dear all,
Thanks again for your help, really appreciated :)
Just bought a Radeon R7 240 off eBay at 45€ including shipping from Italy.
Let's hope this one works correctly with Einstein@Home :)
Best regards,

Best of luck. Hope it works

Best of luck. Hope it works for you also.

Dear all,
Just to let you know that I received the AMD Radeon R7 240 this morning, and it's working correctly :)

I believe it's running FGRPopencl1K-ati 1.18 at the moment, with the AMDGPU driver:
