GPUs are definitely in the performance at the expense of correctness bucket. It's common for errors to occur in the LSB which isn't a big deal for colors, but might be a big deal for data.

Aren't the last few generations of GPUs fully IEEE compliant?

I assume that SapphireSun refers (primarily) to individual manufactured device faults not a problem where the design fails to comply with the floating point standard. EDIT: although the faults I'm referring to would be just as likely in the MSB so maybe not.
SapphireSun, these are mitigated in large part by ECC. It was offered by both major manufacturers and now at least one of them still offers it.
