These values are fairly high, making active cooling solutions something of a necessity. The Ryzen 5 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are allowed to change to anything between 12 W and 35 W if required with clock speeds and performance changing correspondingly. The performance of the Ryzen 5 3450U is slightly behind the Ryzen 3500U at the same TDP configuration due to the slower boost clock (-200 MHz). 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 integrated dual-channel memory controller supports up to DDR4-2400 memory. Furthermore, the 12 nm process allows for higher clocks at similar power consumption. The Picasso SoC uses the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. It combines four Zen+ cores (8 threads) clocked at 2.1 GHz to 3.5 GHz (-200 MHz versus 3500U) with a Radeon RX Vega 8 iGPU with 8 CUs (512 Shaders) clocked at up to 1200 MHz. The AMD Ryzen 5 3450U is a mobile SoC that was announced in Q2 2020 as a refresh.
