Great, here’s the entitled journalist telling me that the $2,000 graphics card won CES 2025. I’ve seen plenty of strong opinions about Nvidia’s CES announcements online, but even ignoring the bloated price of the new RTX 5090, Nvidia won this year’s show. And it kind of won by default. Between Intel’s barebones announcements and an overstuffed AMD presentation that ignored what might be AMD’s most important GPU launch ever, it’s not surprising that Team Green came out ahead.
But that’s despite the insane price of the RTX 5090, not because of it.
Nvidia introduced a new range of graphics cards, and the impressive multi-frame generation of DLSS 4, but its announcements this year were much more significant than that. It all comes down to the ways that Nvidia is leveraging AI to make PC games better, and the fruits of that labor may not pay off immediately.
There are the developer-facing tools like Neural Materials and Neural Texture Compression, both of which Nvidia briefly touched on during its CES 2025 keynote. For me, however, the standout is neural shaders. They certainly aren’t as exciting as a new graphics card, at least on the surface, but neural shaders have massive implications for the future of PC games. Even without the RTX 5090, that announcement alone is significant enough for Nvidia to steal this year’s show.
Neural shaders aren’t some buzzword, though I’d forgive you for thinking that given the force-feeding of AI we’ve all experienced over the past couple of years. First, let’s start with the shader. If you aren’t familiar, shaders are essentially the programs that run on your GPU. Decades ago, you had fixed-function shaders; they could only do one thing. In the early 2000s, Nvidia introduced programmable shaders that had far greater capabilities. Now, we’re starting with neural shaders.
In short, neural shaders allow developers to add small neural networks to shader code. Then, when you’re playing a game, those neural networks can be deployed on the Tensor cores of your graphics card. It unlocks a boatload of computing horsepower that, up to this point, had fairly minimal applications in PC games. They were really just fired up for DLSS.
Nvidia has uses for neural shaders that it has announced so far — the aforementioned Neural Materials and Neural Texture Compression, and Neural Radiance Cache. I’ll start with the last one because it’s the most interesting. The Neural Radiance Cache essentially allows AI to guess what an infinite number of light bounces in a scene would look like. Now, path tracing in real time can only handle so many light bounces. After a certain point, it becomes too demanding. Neural Radiance Cache not only unlocks more realistic lighting with far more bounces but also improves performance, according to Nvidia. That’s because it only requires one or two light bounces. The rest are inferred from the neural network.
Similarly, Neural Materials compresses dense shader code that would normally be reserved for offline rendering, allowing what Nvidia calls “film-quality” assets to be rendered in real time. Neural Texture Compression applies AI to texture compression, which Nvidia says saves 7x the memory as traditional block-based compression without any loss in quality.
That’s just three applications of neural networks being deployed in PC games, and there are already big implications for how well games can run and how good they can look. It’s important to remember that this is the starting line, too — AMD, Intel, and Nvidia all have AI hardware on their GPUs now, and I suspect there will be quite a lot of development on what kinds of neural networks can go into a shader in the future.
Maybe there are cloth or physics simulations that are normally run on the CPU that can be run through a neural network on Tensor cores. Or maybe you can expand the complexity of meshes by inferring triangles that the GPU doesn’t need to account for. There are the visible applications of AI, such as through non-playable characters, but neural shaders open up a world of invisible AI that makes rendering more efficient, and therefore, more powerful.
It’s easy to get lost in the sauce of CES. If you were to believe every executive keynote, you would walk away with literally thousands of “ground-breaking” innovations that barely manage to move a patch of dirt. Neural shaders don’t fit into that category. There are already three very practical applications of neural shaders that Nvidia is introducing, and people much smarter than myself will likely dream up hundreds more.
I should be clear, though — that won’t come right away. We’re only seeing the very surface of what neural shaders could be capable of in the future, and even then, it’ll likely be multiple years and graphics card generations down the road before their impact is felt. But when looking at the landscape of announcements from AMD, Nvidia, and Intel, only one company introduced something that could really be worthy of that “ground-breaking” title, and that’s Nvidia.
Acer’s Predator Atlas 8 finally has a US release date and price, several months after the company first showed off the handheld in May. The highlight is the Intel Arc G3 Extreme chip inside, which has been adopted by only a couple of other consoles besides the Atlas 8. This version will go on sale exclusively at Best Buy on November 1 for $1,299.99.
Acer originally said the Atlas 8 would arrive in North America in October, but left pricing open at the time. The launch came amid the ongoing DRAM crunch, which has made memory more expensive across the PC industry and complicated pricing for hardware makers.
Google DeepMind's AI world model Genie 4 can now build interactive worlds that you can explore and reshape as they run. It also generates ambient sounds, music, and dialogue that respond to your actions.
The new world model builds on Genie 3 with improved realism, more natural human movement, and better simulations of real-world physics. It could eventually help with everything from game development to training robots.
Apple has an incredible talent for making me admire its products while simultaneously questioning what on earth it's thinking with the pricing. This isn't even something as bizarre as a monitor stand, but the audacity for starting a new laptop lineup from $2,000 doesn't surprise me.
The newly announced 14-inch MacBook Pro with M6 is just the latest to showcase this. The funny thing is, I already know that it's going to be a reliable workstation. You get a powerful new 2nm M6 processor, a gorgeous Liquid Retina XDR display, and up to 24 hours of battery life. We were impressed by the M5 MacBook Air, so the high-end M6 powered MacBook Pro definitely won't let us down.
