AMD has launched a Zen 5 laptop chip without an NPU, and gamers are unlikely to shed a tear.
The Ryzen 7 449 has turned up inside Mechrevo’s Phenom 15 Air, giving AMD a neat split in its mobile line-up. Ryzen AI 400 chips get the XDNA 2 neural processor and Copilot+ badge, while Ryzen 400 parts dump the AI block for buyers who would rather spend the budget on a proper GPU.
According to Notebookcheck the new chip shares plenty with the Ryzen AI 7 450. It has four Zen 5 cores, four Zen 5c cores, 16 threads, 16MB of L3 cache and a 15W to 54W power range on TSMC’s 4nm process.
The Ryzen 7 449 boosts to 5.0GHz rather than 5.1GHz, while its Radeon 860M integrated graphics run at 2.8GHz instead of 3.1GHz. In a laptop with a discrete GPU, that is hardly a pub fight.
What is missing is the XDNA 2 NPU, which gives Ryzen AI chips their 50 TOPS rating and Microsoft Copilot+ qualification. Without it, the Ryzen 7 449 delivers about 15-16 TOPS from its CPU and iGPU, which is nowhere near the 40 TOPS of the Copilot+ line.
For a gaming laptop, that missing badge means little. Microsoft’s on-device AI tricks, including Recall, Live Captions, and Windows Studio Effects, do not increase frame rates. An RTX 5060 does rather more for that.
Mechrevo paired the Ryzen 7 449 with an Nvidia GeForce RTX 5060 Laptop GPU that can draw up to 115W. The machine draws up to 170W under combined CPU and GPU load, with dual-fan cooling letting the processor run at up to 85W when needed.
The Phenom 15 Air has a 15.3-inch QHD OLED panel at 240Hz, full DCI-P3 colour coverage, factory calibration, 24GB of LPDDR5X memory, and a 1TB PCIe 4.0 NVMe drive. It weighs about 1.6kg and is 18.75mm thick at its slimmest point, which is rather trim for this class of gaming kit.
It is unclear whether AMD made a separate die without the NPU or is using Gorgon Point silicon with the XDNA 2 block disabled. If it is binning, AMD gets to flog chips that might not have passed NPU muster, which is standard semiconductor penny-pinching rather than dark magic.
Mechrevo launched the machine in China for CNY 11,499, about €1,390. The firm has a North American storefront, but there is no confirmed international launch for this configuration, so overseas buyers may be stuck watching importers.
Mechrevo is a Chinese OEM, which means buyers with data-sovereignty worries should factor in Chinese national intelligence and data laws. No public research has shown a Mechrevo-specific backdoor or confirmed breach.
