This is not true, just like a shader core with AMD was not a GPU thread.
For example, the 2900 XT had 320 shader cores, but since it used VILW-5 ISA, that corresponds to 64 GPU threads.
Similarly, an RTX 3080 has 8704 CUDA cores, but there are 2 FP32 ALUs per thread, resulting in 4252 threads, and 68 SMs since, just like Turing, there are 64 threads per SM.
