The linked CADO-NFS Inria page makes no mention of GPUs, and nor does its downloads page, which makes me think that TFA's factoring was done purely on CPUs. If so, there could still be considerable speedup on the table!
The CADO-NFS page gives some benchmark results for 16 threads, suggesting the algorithm parallelises at least somewhat well.
I didn't use any GPUs, but Steve Weis (who factored the final key at the bottom of the post) did. He's posted about that factoring setup over on https://x.com/sweis/status/2095570645505700165
