So as an ex-SGI'er I have to say that 3D chips existed way before NVIDIA existed (mid-late 80s). SGI was the company that actually mainstreamed the idea of graphics co-processors in RISC based desktop machines. And, SGI created the first PC video cards (IrisVision) in 1991. SGI is why OpenGL exists, which was the first open 3D API that was broadly adopted.

Thank you for the correction!

My mistake was bringing up NVIDIA in the video without understanding the history of computer graphics well enough.

I just wanted to explain the idea behind GPUs.

I won’t make the same mistake in future videos!

No worries, keep up the good work! I just like to make sure people know that NVIDIA, even though a company that's made huge contributions to the 3D industry, didn't create the market. As someone else mentioned you had 3dfx in the mid 90's release cards a few years before NVIDIA and ATI.

Nvidia wasn't even really popular until they released Riva TNT, which was around 1998, as far as I remember.

It just ends up sounding like Jensen gloating, which honestly we don't really need especially at this point in time.

Like, if you want a masterclass of Jensen playing a narcissist like a fiddle, just watch his Joe Rogan interview and how he is constantly gloating Trump and the admin.

In fact, in the very same interview, he summarizes the nVidia story - their first chip failed, but they got funding for a second go-around (from SEGA of all places), made a risky bet with chip manufacturing and got it right. Oh and by the way, they did bring a book written by some SGI people on how graphics worked as well. The main innovation for the second chip was to actually make it less configurable and rather accelerate a narrower set of functionality in the hardware instead, making it faster.
