HP announced its Copilot+ mini PC and all-in-one desktop PCs at CES 2025 in Las Vegas last week. Rather than powering the new devices with Qualcomm chips, HP chose AMD’s Ryzen AI Max chips for the company’s new Z2 Mini G1a — the “world’s most powerful mini workstation” — and Intel Core Ultra 200V processors for the OmniStudio X all-in-one, described by some as a legitimate iMac Pro competitor. The Intel processors have enough power to support Microsoft Copilot+ PC features for the desktop, while the Z2 Mini G1a is also a Copilot+ PC, touting the AI-powered features, image generation, and editing tools available in Windows 11.

“The OmniStudio X all-in-one will come in both 31.5-inch and 27-inch variants, with the ability to configure the PC with up to Intel Core Ultra 7 258V processors,” reports The Verge. “These chips include a 47 TOPS NPU that’s powerful enough to handle Microsoft’s latest Copilot+ PC features.”

The larger model features “a 4K IPS panel that supports HDR 600 and up to 550 nits of brightness, but it’s not a touchscreen display.” The 27-inch version is touchscreen, “but HP has opted for a 1080p IPS display here that can hit up to 300 nits of brightness,” The Verge explains. The smaller desktop “also comes in a non-touch variant at 1080p and even a 4K IPS option that doesn’t support HDR or touch and can reach up to 350 nits.”

According to the Windows Central reviewer, who describes the OmniStudio X as “the world’s first Copilot+ all-in-one PC with a 32-inch 4K display” and his “next computer,” a few companies are entering the Windows all-in-one space, “but HP has arguably won the battle for best Windows AIO this time around.”

He notes the “glorious 27-inch or 32-inch 4K display, incredible Poly Studio sound,” and “access to exclusive Copilot+ features such as Windows Recall, advanced Windows Studio Effects, Click To Do, and much more.”

“It has a built-in 5-megapixel webcam also, which pops out at the top of the PC and even includes Windows Hello face unlock,” he adds. “The webcam can be hidden, too, so you don’t have to have it always pointing at you if you’re privacy conscious. The OmniStudio X 2025 also has built-in human presence detection, which will automatically wake and sleep the computer when you approach and walk away from it.”

In its review, CNET lists the pros as “huge bright 4K display, compact flexible design, strong overall performance, and the cons as “60Hz display not a good match for RTX GPU, fan noise is constant, no Thunderbolt 4 or USB4.”

Early reviews suggest HP also has a winner with the Z2 Mini G1a workstation. PCWorld writes that it “packs more power into a mini PC than you’d ever need,” especially when “you fill it with the most powerful AMD parts on the planet.”

“You can get up to 128GB of RAM and 4TB of storage (or 8TB if you upgrade it yourself with the second M.2 slot). There’s no discrete graphics for these chips, but the integrated Radeon 8000S series should be enough to handle all but the most extreme needs, since you can assign up to 96GB of memory to the graphics in that maximum configuration.”

TechRadar points out that 30 of the mini PCs “can fit in a 42U rack tower,” describing the Z2 Mini G1a as “an advanced mini workstation designed for professionals engaged in demanding tasks such as AI processing, 3D design, and graphics rendering.”

It includes Thunderbolt 4, USB-C, and Ethernet ports. “There are also optional modules for additional USB ports, serial interfaces, or enhanced networking options,” notes TechRadar. “In addition, it supports Wi-Fi 7 for wireless connectivity.”
