After the recent unveiling of the Asus ROG Ally handheld, AMD has announced the release of its Ryzen Z1 chips, a line of Accelerated Processing Units (APUs) made specifically for Steam Deck-style portable gaming devices. Known for its processor know-how and with a focus on low-power devices, AMD has designed these chips to run on as little as nine watts or as much as 30 watts, depending on the demands of the software. This is a significant difference from the AMD Ryzen 7040U series, which can only run on a power supply ranging from 15-30w .
The Ryzen Z1 and Z1 Extreme will sip power and will make good use of every little bit, whether for playing a less demanding 2D game, streaming from GeForce Now or Xbox Game Pass. More importantly, it will offer an additional couple of hours of gameplay before running out of battery life. The Z1 processors were built to optimize voltage curves and to validate entirely new power ranges. Although the hardware is similar to the Ultrabook CPUs of the Ryzen 7 7840U for the Z1 Extreme, and the Ryzen 5 7640U/7540U for the Z1, the differences in the power range are clear to see. Also noteworthy is that Ryzen XDNA AI co-processors will be disabled for the Z1 line, a perfect move since the processing power will be enough for the power sipping device profile of the ROG Ally.
During the PCWorld interview with AMD representative Frank Azor, he revealed that the Z1 line is only designed for a special class of devices like the Ally and Steam Deck. Azor revealed that there are plenty of other AMD processors available for laptops that require similar capabilities, aligning with the customizations made for the Z1 line outlined in the latest details. The ROG Ally is set to launch later this week on May 11th, though information on pricing is still scant. However, if early leaks are correct, Valve may have to consider the competition.
