AMD Athlon PRO 300U

The AMD Athlon PRO 300U is a mobile entry level dual core SoC that was announced in April 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).

The "PRO"-series is the professional variant of the Athlon 300U APU with additional management and security features (e.g., full memory encryption support). Compared to the Athlon 300U, the PRO version is already based on the new Picasso APUs in 12nm and not 14nm.

The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12nm process allows higher clock rates at similar power consumptions.

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.

AMD states that the Picasso APUs are about 8% faster than the predecessors. Therefore, the Athlon 300 should be slightly slower than the Ryzen 3 2200U (2.5 - 3.4 GHz Dual Core with SMT).
