AMD Reveals Next-Gen Handheld Gaming PC Chips At CES 2025, AMD unveiled the Z2, Z2 Go, and Z2 Extreme chipsets -- all powered by Zen 5 CPU cores and designed for handheld gaming PCs. IGN reports: The AMD Zen 2 Extreme, along with lower-specced cousins the Z2 and Z2 Go, are powered by Zen 5 CPU cores. While the Zen 2 Extreme is using a RDNA 3.5-based GPU, the Z2 and Z2 Go are still using RDNA 3 and RDNA 2, respectively. This creates an entire family of APUs (Advanced Processing Units) for handheld gaming PCs that should hopefully cause the price of handhelds to go down a bit.
With the Z2 Extreme, AMD is hoping to dramatically improve battery life, while also delivering console-like gaming performance to devices like the Lenovo Legion Go. By and large, the biggest limiting factor of these handhelds, especially at the high end, is how quickly their batteries drain when playing demanding games away from a wall outlet. The company also introduced the "Fire Range" HX3D processors for gaming laptops, leveraging 3D V-cache technology for enhanced gaming performance and efficiency. "All of these mobile chipsets, from 'Fire Range' HX3D to the AMD Z2 Extreme, will end up in gaming laptops and handhelds over the next few months," adds IGN.
AMD published a press release with additional details and specifications.

Nvidia Launches RTX 50 Blackwell GPUs: From the $2,000 RTX 5090 To the $549 RTX "Nvidia has officially introduced its highly anticipated GeForce 50 Series graphics cards, accompanied by the debut of DLSS 4 technology," writes Slashdot reader jjslash. "The lineup includes four premium GPUs: the RTX 5080 and RTX 5090 are slated for release on January 30, with the RTX 5070 and RTX 5070 Ti following in February. TechSpot recount of the Jensen Huang keynote tries to differentiate between dubious performance claims and actual expected raw output": The new RTX 5090 flagship comes packing significantly more hardware over its predecessor. Not only does this GPU use Nvidia's new Blackwell architecture, but it also packs significantly more CUDA cores, greater memory bandwidth, and a higher VRAM capacity. The SM count has increased from 128 with the RTX 4090 to a whopping 170 with the RTX 5090 -- a 33% increase in the core size. The memory subsystem is overhauled, now featuring GDDR7 technology on a massive 512-bit bus. With this GDDR7 memory clocked at 28 Gbps, memory bandwidth reaches 1,792 GB/s -- a near 80% increase over the RTX 4090's bandwidth. It also includes 32GB of VRAM, the most Nvidia has ever provided on a consumer GPU. [...]
As for the performance claims... Nvidia has - as usual - used its marketing to obscure actual gaming performance. RTX 50 GPUs support DLSS 4 multi-frame generation, which previous-generation GPUs lack. This means RTX 50 series GPUs can generate double the frames of previous-gen models in DLSS-supported games, making them appear up to twice as "fast" as RTX 40 series GPUs. But in reality, while FPS numbers will increase with DLSS 4, latency and gameplay feel may not improve as dramatically. [...] The claim that the RTX 5070 matches the RTX 4090 in performance seems dubious. Perhaps it could match in frame rate with DLSS 4, but certainly not in raw, non-DLSS performance. Based on Nvidia's charts, the RTX 5070 seems 20-30% faster than the RTX 4070 at 1440p. This would place the RTX 5070 slightly ahead of the RTX 4070 Super for about $50 less, or alternatively, 20-30% faster than the RTX 4070 for the same price. These GeForce 50 series wasn't the only announcement Nvidia made at CES 2025. The chipmaker unveiled a $3,000 personal AI supercomputer, capable of running sophisticated AI models with up to 200 billion parameters. It also announced plans to introduce AI-powered autonomous characters in video games this year, starting with a virtual teammate in the battle royale game PUBG.

Lenovo's Latest Laptop Has a Rollable OLED Screen An anonymous reader quotes a report from Wired: Laptop screens can feel cramped. But what if you could magically get more real estate without having to carry around a portable monitor? That's precisely the purpose of Lenovo's ThinkBook Plus Gen 6 Rollable AI PC -- yes, rollable. It has an OLED display that, with the push of a button, extends the 14-inch screen upward to make for an awkward aspect ratio, but roughly doubles the screen space to 16.7 inches. Two screens are better than one for productivity, but what if one screen could be two but still one? Yes.
It plays a fun animation and some music when it does its rolling thing. You can also activate the rolling action with a palm gesture; once it scans your palm, shift it up or down to raise or lower the screen. (Pressing the button on the keyboard is way faster.) You can take advantage of Windows 11 window snapping features to put apps one on top of the other. I stacked two browser windows, but you can put other apps below too. Considering I'm already that guy who brings a spare portable monitor everywhere, this just seems like a more elegant solution that takes up less space in my bag. And of course, anyone can take advantage of the long aspect ratio to get a better look at documents, PDFs, and web pages.
Lenovo says it has tested the rolling function 30,000 times, and it has performed without flaws, so you can rest a little easier about reliability, though repairing this machine sounds like it will be a task. The whole laptop doesn't feel significantly different from a normal machine, weighing just 3.7 pounds -- that's 1 pound less than the 16-inch MacBook Pro. However, walking with your laptop open in your hand might be weird, as it feels a little top heavy. When closed, it's 19.9 mm thin -- the 16-inch MacBook Pro is 15.4 mm, so Lenovo's machine is thicker, but not as thick as a gaming laptop. Lenovo published a concept video on YouTube.
