AMD Athlon Gold 3150U vs AMD Athlon Gold 7220U vs AMD Ryzen 3 7320U

AMD Athlon Gold 3150U

The AMD Athlon Gold 3150U is a mobile processor for thin and light entry level laptops. It is based on the Dali series (Raven Ridge Dual Core) and offers two Zen cores clocked at 2.6 to 3.3 GHz with SMT (four threads at once) and 4 MB L3-Cache. The integrated graphics card is called Radeon RX Vega 3 and offers only 3 CUs (192 Shaders) clocked at up to 1000 MHz.

In Chromebooks, AMD calles the APU AMD Athlon Gold 3150C, but with the exact same specifications (and performance).

Performance

The average 3150U in our database is in the same league as the Core i3-10110U, as far as multi-thread benchmark scores are concerned. In other words, this is an entry-level chip, as of mid 2022. While not slow by any means, it is anything but fast, either.

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.

Power consumption

The Athlon has a default TDP, also known as the long-term power limit, of 15 W that laptop makers are free to change to anything between 12 W and 25 W with clock speeds and performance changing accordingly as a result. Most will go for a higher value to reach higher performance levels. Either way, an active cooling solution will be needed to dissipate the heat.

The AMD 3150U is built with a 14 nm manufacturing process resulting in low, as of early 2023, energy efficiency.

AMD Athlon Gold 7220U

The AMD Athlon Gold 7220U is a mobile processor for cheap laptops of the Mendocino series. It integrates two older Zen 2 cores (similar to the Ryzen 4000 series). The CPU cores clock from 2.4 GHz (base) to 3.7 GHz (single core Turbo) and can use 4 MB L3 cache. Thanks to SMT/Hyperthreading, the CPU can work on 4 threads simultaneously. The integrated memory controller only supports fast LPDDR5 memory (5500 MHz max.). Compared to the faster Mendocino models like the Ryzen 5 7520U, the 7220U offers only two cores and reduced clock speeds, leading to a clearly lower CPU performance.

The integrated graphics card (Radeon 610M iGPU) uses the modern RDNA 2 architecture, but only 2 CUs (128 shaders) and clocks with up to 1.9 GHz.

The CPU performance should be better than the fastest Ryzen dual-core (Ryzen 3 3250U, 2.6 - 3.5 GHz, Zen 1) but clearly stay behind modern quad-core CPUs (in multi threaded tests).

The Mendocino series are produced in a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The Athlon Gold 7220U is rated at 8-15 W TDP and therefore well suited for thin and light laptops.

AMD Ryzen 3 7320U

The AMD Ryzen 3 7320U is a mobile processor for cheap laptops of the Mendocino series. It integrates four older Zen 2 cores (similar to the Ryzen 4000 series like the Ryzen 3 4300U). The CPU cores clock from 2.4 GHz (base) to 4.1 GHz (single core Turbo) and can use 4 MB L3 cache. Thanks to SMT/Hyperthreading, the CPU can work on 8 threads simultaneously. The integrated memory controller only supports fast LPDDR5 memory (5500 MHz max.). Compared to the fastest Mendocino model the Ryzen 5 7520U, the 7320U offers lower clocked CPU cores (400 MHz base, and 200 MHz Turbo).

The integrated graphics adapter (Radeon 610M iGPU) uses the modern RDNA 2 architecture, but only 2 CUs (128 shaders) and clocks with up to 1.9 GHz.

Performance

We have not tested a single system built around the 7320U, as of September 2023. Expect the chip to be about as fast as the Ryzen 3 3100 (four Zen 2 cores running up to 3.9 GHz).

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your laptop is.

Mendocino series chips are produced on a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The R3 7320U is rated at 8-15 W TDP and therefore well suited for thin and light laptops.
