The goal for the 15–30W thermal envelope is designated by the U suffix.
The top-tier Ryzen 7 7840U has eight CPU cores that support multi-threading, creating a total of 16 threads.
It contains 12 GPU computing units, a 16MB L2 cache, and a maximum performance of 5.1GHz.
AMD is now prepared to deploy more power-optimised versions geared at high-end ultra-slim laptops following the introduction of its efficient Ryzen 7000-series CPUs for personal computers and mainstream laptops.
At the time of its release, the Ryzen 7040U series, code-named "Phoenix," included four CPU variants and was built on the current-generation "Zen 4" architecture with RDNA3 graphics functionality. Major manufacturers will introduce laptops using these new chips in the upcoming weeks, but there is currently no information on availability.
The Ryzen 7000 line of laptop processors were mostly originally introduced at CES 2023, but specifics of the latest 7040U series have just recently become known. The first digit in AMD's new numbering system denotes the launch date, the second digit is the relative power associated with every CPU in a series, and the third digit is the Zen architecture generation used. The goal for the 15–30W thermal envelope is designated by the U suffix. The Ryzen 3 7440U, Ryzen 5 7540U, Ryzen 5 7640U, and Ryzen 7 7840U are the models that make up this series.

The top-tier Ryzen 7 7840U has eight CPU cores that support multi-threading, creating a total of 16 threads. It contains 12 GPU computing units, a 16MB L2 cache, and a maximum performance of 5.1GHz. AMD claims that the 7840U can beat both the Intel Core i7-1360P and Apple's M2 in a few broad performance categories, specifically in the ultra-thin laptop SKUs.
Both Ryzen 5 models have six cores, 12 threads, 16MB of L2 cache memory, and as you move down the line, either eight or four GPU CUs. The base Ryzen 3 7440U has four CUs, four cores, eight threads, and just 8MB of L2 cache.
The two higher-end components are AMD's first CPUs with Ryzen AI circuitry for accelerating artificial intelligence. This particular FPGA was created specifically for on-package use by Xilinx, which AMD took over in 2022.
The Microsoft Studio Effects store in Windows 11 may redefine video calls according to the head's position, filter out noise from the background, correct the way you look to make it appear like you're gazing right away into the camera and blur your background, among other "advanced features" that the company claims deliver "magical new experiences" and "magical new features."

In addition to competing with Apple's current-generation M2 and Intel's 13th Gen P-series CPUs, AMD is asserting its superiority in professional workloads and content creation. RDNA 3 graphics architecture, which supports ray tracing acceleration, GPU power will be a key selling point.
Smart power management is also supposed to significantly increase battery life for laptops, although AMD has still not released any predicted runtime figures. The solutions used by laptop makers and the way they emphasise weight and elimination of heat will, of course, affect real-world performance.
