MagyarAMD Ryzen 7 3780U
The AMD Ryzen 7 3780U,a Microsoft Surface edition chip, is a mobile SoC that was announced in Oct 2019 as part of the new Surface Laptop 15. It combines four Zen+ cores (8 threads) clocked at 2.3 - 4 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (704 Shaders) clocked at up to 1400 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops.
Compared to the similar Ryzen 7 3700U, the 3780U offers the faster Vega 11 instead of the Vega 10 GPU.
The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPC (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.
Performance
While we have not tested a single system powered by the 3780U as of August 2023, it's safe to expect the chip to be about as fast as the Ryzen 7 3700U, as far as multi-thread performance is concerned.
