 CES is a great place to check out all sorts of upcoming tech for the year, but it's often the wildest gadgets that steal the show. The conference hosts thousands of exhibitors, all vying for attention, and you really never know what they're gonna come up with. And this year's show did not let us down. So without further ado, here's the weirdest tech at CES 2025 that we encountered — all of the crazy (and crazy useful) devices we spotted out in the wild of the show floor. Just keep in mind, weird doesn't necessarily mean bad — we actually want to buy some of these! They're just not quite the run-of-the-mill laptop or TV from the big vendors that dominated the show floor.

Nvidia certainly stole the show, with the GeForce RTX 50 Series announcement serving as the key opening message in CEO Jensen Huang's keynote speech. AMD was much softer in its talk, with sparse details on its new RDNA 4 graphics cards, resulting in similarly sparse enthusiasm.
Let's go over what we learned from both companies about their GPUs and where your attention should be in 2025.
The good and the almost good…
Right off the bat, here's the good news for us: We're definitely getting some new GPUs, starting with Nvidia's GeForce RTX 50 Series. The top-dog in that group will be the RTX 5090, featuring a staggering 32GB of fast GDDR7 VRAM. According to Nvidia, it may be as much as twice as fast as the outgoing flagship RTX 4090.
While that's certainly impressive, Nvidia is likely basing its claims on its DLSS 4 numbers, which feature several new technologies that help it achieve all this. Chief among them is Multi Frame Generation, using the power of AI to reach higher peaks in performance with little to no apparent drawbacks.

 If you spot a snazzy silver ebike at CES this week, you should know that it's more than just a pretty face. It's the 3D-printed Titanium Zero, and it sports what is claimed to be the world's smallest, lightest, highest-torque-density motor.
