The AMD Athlon Gold 3150U is a mobile processor for thin and light entry level laptops. It is based on the Dali series (Raven Ridge Dual Core) and offers two Zen cores clocked at 2.6 to 3.3 GHz with SMT (four threads at once) and 4 MB L3-Cache. The integrated graphics card is called Radeon RX Vega 3 and offers only 3 CUs (192 Shaders) clocked at up to 1000 MHz.
In Chromebooks, AMD calles the APU AMD Athlon Gold 3150C, but with the exact same specifications (and performance).
Performance
The average 3150U in our database is in the same league as the Core i3-10110U, as far as multi-thread benchmark scores are concerned. In other words, this is an entry-level chip, as of mid 2022. While not slow by any means, it is anything but fast, either.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Power consumption
The Athlon has a default TDP, also known as the long-term power limit, of 15 W that laptop makers are free to change to anything between 12 W and 25 W with clock speeds and performance changing accordingly as a result. Most will go for a higher value to reach higher performance levels. Either way, an active cooling solution will be needed to dissipate the heat.
The AMD 3150U is built with a 14 nm manufacturing process resulting in low, as of early 2023, energy efficiency.
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.
Performance
The average 3450U in our database is in the same league as the Core i3-1115G4 and also the Ryzen 3 4300U, as far as multi-thread benchmark scores are concerned. This is a better-than-expected result for an aging lower mid-range chip that is the 3450U, as of mid 2022.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
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.
