AMD is fleshing out its Ryzen 7000 mobile processor family with the introduction of its new Ryzen Mobile 7040U processor family.

With support for up to 8 Zen 4 CPU cores and integrated graphics with up to 12 RDNA 3 compute units, the new chips look a lot like the Ryzen 7040HS chips that the company announced earlier this year (and which are now shipping to PC makers). The key differences are that the new U-series chips consume less power and cover a wider range of price/performance points, which could make them a good fit for affordable thin and light laptops and mini PCs.

The most powerful of the new Ryzen 7040U chips is the Ryzen 7 7840U, which is a 4nm processor with 8 CPU cores, 16 threads, support for speeds up to 5.1 GHz, Radeon 780M integrated graphics and 24MB of total cache.

But there are also more affordable options including ranging from the 4-core Ryzen 3 7440U with Radeon 740M graphics to the 6-core Ryzen 5 7640U with a Radeon 760M GPU.

AMD says all of the chips have a default TDP of 28 watts, which puts them in competition with Intel’s 13th-gen Core P-series chips. But these processors can also be configured to use as little as 15 watts, like Intel’s Core U-series chips, or as much as 30 watts.

All of AMD’s Ryzen 7040 series processors also support USB4, DDR5 and LPDDR5 memory, and graphics features including hardware-accelerated ray tracing. And they also all have AMD’s new AI engine for hardware-accelerated AI tasks. This feature is courtesy of an FPGA built into the chips.

Here’s a run-down of the complete Ryzen 7040U series:

If some of the specs above look familiar, there’s good reason for that: AMD has already announced two chips that are nearly identical to the Ryzen 7 7840U and Ryzen 5 7540U.

The company’s Ryzen Z1 Extreme and Z1 chips are rebranded versions of these chips that are marketed as chips for handheld gaming PCs like the upcoming Asus ROG Ally, which is one of the first devices expected to ship with a Ryzen Z1 series processor (or Ryzen 7040U series chip, for that matter).

AMD says it’s fine tuned the performance and power consumption settings for the Z1 versions of these chips, but they’re basically the same processors we’ll likely see in laptops when models with Ryzen 7040U series hit the streets later this year. Some PC makers have already begun to announce plans to release laptops with the new chips.
