A lot of noise but can't seem to find anything factual... anyone knows?
it does not
does that mean it's the same as the S?
That would make sense from a manufacturing/cost/software standpoint. Every year chips get cheaper, the software can be the same as the S, and building 1 thing is easier than building 2 things...
I would be shocked if they still use the same chipset from 2012 though, same goes for the S. The screen in my classic is really slow (same goes for nav, drawling lines) and loaners seem to be alot snappier, so maybe it's already upgraded in the S. Wish someone could confirm.
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.
How do you know? Source?
Spoke to a manager the NVidia X1 product team a couple of weeks ago. He said that Tesla tested the X1 but went with the same hardware as in the Model S in the end. Which would explain the one mule people caught with eight(?) cameras.
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 cockpitWe 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.
Yes the K1 is the previous generation of the X1. The original Model S used the Tegra 3 which is 2 generations back from the K1.
The current gen Model S still uses a Tegra 3. They should've at least bumped it up to a 4.
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.
Uses K1 based on article on this post, and previously was using Tegra 4 for MCU and Tegra 3 for dash
Why resurrect this old thread with false info? Model X is the same as Model S. It's vintage Tegra 3, no faster... no slower. Same old school WiFi, too.
t the very least according to these security guys who have opened everything the 17" is running Tegra 4, who knows maybe the dash does now as well
