AMD Ryzen 7 3780U vs AMD Ryzen 5 PRO 3500U

AMD Ryzen 7 3780U

The AMD Ryzen 7 3780U (Microsoft Surface Edition) 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.

AMD states that the Picasso APUs are about 8% faster than the predecessors. Therefore, the Ryzen 7 3780U should be slightly ahead the Ryzen 7 2700U. In our benchmark the Ryzen 7 3700U and therefore also the 3780U could not pull ahead much compared to the average Ryzen 7 2700U.

AMD Ryzen 5 PRO 3500U

The AMD Ryzen 5 PRO 3500U is a mobile SoC for business laptops that was announced in April  2019. It combines four Zen+ cores (8 threads) clocked at 2.1 - 3.7 GHz with a Radeon RX Vega 8 graphics card with 8 CUs (512 Shaders) clocked at up to 1200 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. Compared to the similar consumer variant Ryzen 5 3500U, the PRO model features additional management and security features (e.g., full memory encryption) and longer warranty / availability.

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.

AMD states that the Picasso APUs are about 8% faster than the predecessors. Therefore, the Ryzen 5 3500U should be ahead the Ryzen 5 PRO 2500U (2 - 3.6 GHz) and nearly on par with the Ryzen 7 PRO 2700U (2.2 - 3.8 GHz).
