Based on Zen 2 series Ryzen and Athlon 7020 with RDNA 2 graphics

3 min read


While the main focus this month has been on AMD’s upcoming release of its Ryzen 7000 desktop processors based on the Zen 4 architecture, AMD is also in the process of releasing its entry-level mobile 7020 processor series with code name Mendocino. It launched four new mobile SKUs, including two Ryzen-series models and two Athlon variants, all based on its Zen 2 architecture.

As we learned in May, AMD’s Zen 2-based ‘Mendocino’ APUs are designed as part of a lower-end mobile processor stack for entry-level solutions for thin notebooks and laptops. Affordable APUs include up to 4 Zen 2 CPU cores as well as AMD’s integrated Radeon 610M graphics, all with a maximum TDP of 15W.

Focusing specifically on the AMD 7020 series APUs announced today, the top SKU is the Ryzen 5 7520U. Using AMD’s new Ryzen Mobile processor numbering system, the 7520U is a 2023 model year chip under the Ryzen 5 series banner, using its Zen 2 core architecture. The U suffix technically means 15-28W, but in this case AMD has confirmed that all current chips have a maximum TDP of 15W.

The AMD Ryzen 5 7520U benefits from a 2.8 GHz base frequency across its four cores, with a 1T boost frequency up to 4.3 GHz. It also includes a total of 6MB cache, spread between 4MB L3 and 2MB L2 (512KB per core).

Ryzen 5 7520U 4C / 8T 2.8GHz 4.3 GHz 2MB L2 + 4MB L3 Radeon 610M 15W
Ryzen 3 7320U 4C / 8T 2.4GHz 4.1 GHz 2MB L2 + 4MB L3 Radeon 610M 15W
Athlon Gold 7220U 2C / 4T 2.4 GHz 3.7 GHz 1MB L2 + 4MB L3 Radeon 610M 15W
Athlon Silver 7120U 2C / 4T 2.4GHz 3.5GHz 1MB L2 + 2MB L3 Radeon 610M 15W

Moving down the stack is the Ryzen 3 7320U, which has four cores and eight threads, but a base core clock of 2.4 GHz and a single core boost frequency of up to 4.1 GHz. Like the Ryzen 5 7520U, it also benefits from a combined 6MB cache in its L2/L3 cache structure.

Looking at the Athlon-branded 7020 series chips, the Athlon Gold 7220U offers two cores and four threads, with a base frequency of 2.4 GHz, a single-core boost frequency of up to 3.7 GHz, and 5 MB of shared L2/L3 cache. The Athlon Silver 7120U is almost the Athlon Gold 7220U, but has a slightly lower 1T boost frequency of 3.5 GHz and half the L3 cache (for a total of 3MB instead of 5MB)



AMD Radeon 610M with two graphics cores for entry-level performance

All of AMD’s Zen 2 Ryzen and Athlon 7020 series announced today will support up to 32GB of LPDDR5 memory in a dual-channel (64-bit) configuration and feature two graphics cores/CUs based on its RNDA 2 technology, which AMD is branding the integrated Radeon 610M graphics chip. All four mobile APUs will feature TDPs of up to 15W.

At the time of writing, AMD hasn’t revealed specific pricing, other than a general price range for the laptop between $399 and $699. However, it has announced that its AMD Ryzen 7020 Series Ecosystem partners are Acer, HP, Lenovo and Microsoft, with notebooks with these chips expected to start hitting retail shelves sometime in Q4 2022.
