Okay, let's actually stop and think for 2 seconds instead of instantly going to our respective Green and Red fortresses and flinging mortars at each other over the walls.
The argument, such as it is, is that Nvidia intentionally gimped performance of Titan X Pascal and Titan Xp to sell more Quadro. This is why that argument is a fallacy.
(1) For the purposes of professional applications, the big draw of Quadro is driver certification. Nvidia actually works with vendors of important software packages like Maya, 3D Studio MAX, AutoCAD, etc. to certify their drivers work correctly and contain no performance killing or crashing bugs. This not cheap. Most of the Quadro tax is paid for certified drivers.

(2) The consumer Geforce drivers are not certified and may contain notable bugs which kill performance in untested professional applications. This is more likely than intentional gimping, especially since the same Geforce drivers are used for Titans which have the full GP102 core and the 1080 and 1070 which have a GP104 core which
in hardware doesn't support full FP16 compute performance. Nvidia probably never bothered to test compute performance against drivers on Pascal-gen Titans simply because other Pascals literally don't have the same hardware for compute.

(3) Nvidia isn't suddenly afraid of Vega FE or even consumer Vega for professional applications, because Vega uses Radeon drivers and not certified FirePro drivers. No actual professionals will use Vega FE or RX Vega for professional applications anymore than they use Titan Xp for them. See (1). Also,
Titan Xp already outperforms Vega FE in the applications that got a boost from this driver. They didn't need to do anything to already have their $1,200 Titan Xp outperform the $1,500 Vega FE in the majority of tested applications.

(4) It's not actually 3x performance, like everything is suddenly 3 times faster. I mean Nvidia is known for exaggerating performance but this is hilarious. If they had just said it's actually like 50-100% performance boost only in certain applications and benchmarks which use that applications maybe it wouldn't look like intentional gimping. But Nvidia has never cared about this because why would they?

(5) The Quadro P6000 has 24 GB of VRAM. The Titan Xp has 12 GB of VRAM. You might not think this is a big deal but professionals do. Quadro also support 10-bit color while consumer Pascal is limited to 8-bit color. Again: you do not care. Professionals do. It turns out that you also need FirePro for 10-bit color on the AMD side, you are also limited to 8-bit color on the Radeon cards.
(6) Big secret: If you aren't an actual professional and don't need 24 GB of VRAM, the actual real-world performance of a lot of these pro tools isn't really much different between consumer Pascal and Quadros. This was true even before this driver was released.

Conclusion:
Nvidia is not likely to be intentionally gimping Titan in order to sell more Quadro, because if they really wanted to make sure no one could use Titan for compute they would have just sold a GPU core which literally didn't have the hardware for it like 1080 and 1070. It's more likely that the consumer Geforce drivers simply didn't have functional code for some compute hardware that was never even in normal consumer Pascal but now it's been fixed or even added from the Quadro branch. Furthermore as I have mentioned, many of the benefits of Quadro have always been for professional applications and performance has never been that dissimilar when a non-pro is using a consumer card to run some of these pro software programs.
You're welcome to question the
timing of this sudden miraculous performance boost, but Nvidia seems pretty determined to do things their way and it's not like AMD is in a competitive position to stop them.
What's interesting is the original Titan X Pascal benefits from this too:

Which implies the 1080 Ti might also benefit, although no one seems to have benchmarked it yet.
