AMD Athlon Gold 3150U vs AMD Athlon 300U

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 300U

The AMD Athlon 300U is a mobile entry level dual core SoC that was announced in January 2019. It combines two Zen cores (with SMT / Hyperthreading so running 4 threads) clocked at 2.4 - 3.3 GHz with a Radeon RX Vega 3 graphics card with 3 CUs (192 Shaders) clocked at up to 1000 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. It is quite similar to the AMD Ryzen 3 3200U (2.6 - 3.5 GHz).

Compared to the Picasso APUs of the Ryzen 3000 series, the Athlon 300U is still based on the first generation of the 2000 series. Only the PRO variant is based on the new Zen+ microarchitecture that should lead to a 3% IPS (performance per clock) improvement.

The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

In contrast to the faster quad-core Picasso APUs, the Athlon 300U only supports 3 instead of 4 displays in total.

Performance wise, the Athlon 300 should be slightly slower than the Ryzen 3 2200U (2.5 - 3.4 GHz Dual Core with SMT).
