This has not been my experience in the academic/research side. Poison solver-based incompressible CFD regularly runs ~10x faster on equivalently-priced GPU systems, and has been doing so since I've been following it (since 2008). Some FFT-based solvers don't weak scale ideally, but that'd be even worse for CPU-based versions, as they use similar algorithms and would be spread over many more nodes.
