AMD Ryzen 5 3580U

The AMD Ryzen 5 3580U (Microsoft Surface Edition) is a mobile SoC that was announced in October 2019 as part of the Surface Book 15. It combines four Zen+ cores (8 threads) clocked at 2.2 - 3.8 GHz with a Radeon RX Vega 9 graphics adapter with 9 CUs (576 Shaders) clocked at up to 1300 MHz. Compared to the similar Ryzen 5 3500U, the 3580 integrates a faster GPU with 9 instead of 8 CUs.

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.

As the Ryzen 5 3580U CPU specification is identical to the Ryzen 5 3500U, the processor performance should be similar. AMD states that the Picasso APUs are about 8% faster than the predecessors. Therefore, the Ryzen 5 3500U and 3580U should be ahead the Ryzen 5 2500U (2 - 3.6 GHz) and nearly on par with the Ryzen 7 2700U (2.2 - 3.8 GHz).

Power consumption

This Ryzen 5 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers - or should we say, Microsoft - are allowed to change to anything between 12 W and 35 W with clock speeds and performance changing correspondingly. Those values are not low enough to allow for fan-free designs, for better or worse.

The CPU is built with a fairly old, as of late 2022, 12 nm process for lower-than-average energy efficiency.
