Does Model X use the new Tegra X1 Chipset?

it does not

You seem to be confident in your answer. How so?

Tegra X1 is a significant leap forward over the last generation chip. It's capable of significantly improving both autopilot and active safety systems. Since Nvidia's CEO is quite vocal about owning a Founder Model X, it makes sense to see Tesla as the pilot customer for the new chip.

Oh, well... at this point, anything will suffice.
 
As per this article, Tesla upgraded the chipset for both the S and X to the Tegra K1 (VCM):


Tesla vehicles do not (currently) have Nvidia’s Drive PX/CX board and instead rely on the Tegra K1 (VCM) to power the digital cockpit

We were also able to find out the exact Tegra model present in the new Tesla EVs. Previously, the cars possessed a Tegra 3 processor, but all modern Model Xs and Model S cars will have the Nvidia VCM (Visual Computing Module). NVIDIA has a long-standing relationship with many automakers including Audi, Volkswagen and BMW. These partners are now using the Tegra Visual Computing Module (VCM) for their infotainment systems. The VCM is a highly flexible platform, incorporating an automotive-grade NVIDIA Tegra mobile processor with dedicated audio, video and image processors. Nvidia revealed their VCM module a year or so back and it consists of the Tegra K1 with a grand total of 384 GFlops. To put that into perspective, that is more power than last generation consoles (PS3/Xbox 360).

Please forgive the stupid (noob) question: Is the Tegra K1 the "old chipset"? Is it different from the X1?

My understanding is that the X1 uses a different, newer microarchitecture than the K1. For driving the displays in a Tesla, the K1 is probably more than powerful enough. When I test drove a P90D, the touch interface was very responsive.
 
How do you know? Source?

This was confirmed during the launch of the X. Reporters were told the GPU was the same, but the touchscreen itself received a minor upgrade to be more sensitive. The same reporters also said it felt exactly the same as the S.

Of course, this doesn't mean the production version won't have it, but no upgrade was mentioned at launch.

As of now, Nvidia has nothing to do with Autopilot or safety systems. That's handled by Mobileye. It doesn't mean it can't change, but for now Nvidia is strictly for the center console, like your computer's video card.
