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).
