The AMD Ryzen 7 3700U is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (8 threads) clocked at 2.3 - 4 GHz with a Radeon RX Vega 10 graphics card with 10 CUs (640 Shaders) clocked at up to 1400 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. In Chromebooks, AMD calles the APU AMD Ryzen 7 3700C, but with the exact same specifications (and performance).
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.
The performance of the Ryzen 7 3700U is heavily depending on the TDP settings and the cooling solution of the laptop. The average 3700U at the time of writing is only as fast as a older Ryzen 5 2500U (in our performance rating). This comes from the differences of performance in different laptops. For example, the ThinkPad E595 offers a miles better short and long-term CPU performance compared to the HP Envy x360 (see Cinebench R15 loop below). Compared with Intel CPUs, the Ryzen 7 is on par with a Core i5-8250U on average, but e.g. in the E595 it can be matched with higher end Intel counter parts. However, even the slow examples offer enough performance for demanding multi tasking.
The AMD Ryzen 3 3250U is a dual-core SoC that was announced in 2020. The Ryzen 3 features two Zen cores (with SMT support for a total of 4 threads) clocked at 2.6 GHz to 3.5 GHz and a Radeon RX Vega 3 graphics adapter with 3 CUs (192 unified shaders) clocked at up to 1,200 MHz. The default TDP is 15 W which makes the Ryzen a good fit for thin mid-range laptops. The specifications are similar to the older Ryzen 3 3200U with the lower max. operating temperature (95 °C versus 105 °C) being the only difference betwen the two.
A special edition of the Ryzen 3 3250U designed specifically for Chromebooks is called the AMD Ryzen 3 3250C. The specifications and performance appear to be identical between the two.
The Ryzen 3 is manufactured on a 14 nm process and compatible with single-channel or dual-channel DDR4-2400 RAM. Please go to our Raven Ridge launch article for details on the architecture and more.
