AMD Ryzen 3 3300U vs AMD Ryzen 5 3580U

AMD Ryzen 3 3300U

The AMD Ryzen 3 3300U is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (no SMT / Hyperthreading so only 4 threads) clocked at 2.1 - 3.5 GHz with a Radeon RX Vega 6 graphics card with 6 CUs (384 Shaders) clocked at up to 1200 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops.

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 3 3300U should be similar to the Ryzen 5 2500U (2 - 3.6 GHz but with SMT).

AMD Ryzen 5 3580U

The AMD Ryzen 5 3580U, a Microsoft Surface Edition chip, 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.

Performance

The average 3580U in our extensive database is in the same league as the Core i5-1035G7 and also the Core i7-10510U, as far as multi-thread benchmark scores are concerned. This is a fairly decent result, as of mid 2021.

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.
