AMD Ryzen 3 3300U vs AMD Ryzen 5 3450U vs AMD Ryzen 7 PRO 3700U

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 3450U

The AMD Ryzen 5 3450U is a mobile SoC that was announced in Q2 2020 as a refresh. 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 Picasso SoC uses the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12 nm process allows for higher clocks at similar power consumption.

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 5 3450U is slightly behind the Ryzen 3500U at the same TDP configuration due to the slower boost clock (-200 MHz).

Power consumption

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. These values are fairly high, making active cooling solutions something of a necessity.

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

AMD Ryzen 7 PRO 3700U

The AMD Ryzen 7 PRO 3700U is a mobile SoC for business laptops that was announced in April 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. Compared to the similar consumer variant Ryzen 7 3700U, 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.

AMD states that the Picasso APUs are about 8% faster than the predecessors. Therefore, the Ryzen 7 PRO 3700U should be slightly ahead the Ryzen 7 PRO 2700U.
