The parent is probably referring to the Quadro (cad workstation) vs Geforce (gaming) split, not the Geforce vs HPC. There's a history of limiting Geforce performance for CAD workflows in software, and flashing the firmware of Geforce cards to unlock much better "professional" performance.
The flashing didn't increase performance it allowed you to use Quadro certified drivers which are available now for Geforce (minus the official certification and support iirc) too (i think they are called creator drivers or something like that).
This also impacted only a tiny subset of CAD/professional imaging products which were out of reach of consumers anyhow often due to the massive PITA and cost that was certifying your hardware and drivers for those products.
Quadro wasn't running faster in Blender, 3DSM not even AutoDesk (in fact they were often slower due to lower frequencies), the apps were it made a difference when those drivers were finally released for Geforce and Titan cards were only the likes of Catia and Siemens NX hardly consumer/prosumer software.
I'm sorry but if you are a 7 figure a year license holder for Siemens NX spending $2000-3000 extra per on each GPU every 3 year isn't going to be an issue, not to mention that you aren't going to be using Geforce GPUs anyhow as the drivers are still not certified (which is required for the industry) and even more likely you'll be buying certified workstations from the likes of HP and Dell.
This is absolutely not true, gaming focused Geforce cards have intentionally firmware crippled 64bit float performance, and the Quadro firmware flashes unlocked it.
