Every year they drop a "new GPU!" announcement with absolutely no details. All their numbers are "in simulation only".

Last year it was their "Thunder" architecture being the world's fastest GPU, now it's Zeus. Neither one actually exists. https://bolt.graphics/bolt-graphics-unveils-thunder-the-worl...

All their blog posts and marketing material are just generic hype about the concept of raytracing. I don't think these guys have an actual product.
