AMD Ryzen 3 5300U vs AMD Ryzen 7 3780U

AMD Ryzen 3 5300U

The AMD Ryzen 3 5300U (not to be confused with the A4-5300, a CPU released in 2012) is a Lucienne family processor designed for use in thin and light laptops. The R3 5300U integrates four cores (quad core) based on the Zen 2 microarchitecture. They are clocked at 2.6 (guaranteed base clock) to 3.8 GHz (Turbo) and support SMT for a total of 8 threads. The chip is manufactured on the modern 7 nm TSMC process. Compared to the older and similar Ryzen 3 4300U (Renoir), the Ryzen 3 5300U offers SMT and slightly higher clock speeds. The faster Ryzen 3 5400U is based on the newer Zen 3 architecture. See our hub page on the Renoir Processors for more information on the Lucienne / Renoir architecture.

In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics adapter with 6 CUs at up to 1500 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 4 MB level 3 cache can be found on the chip.

Performance

The average 5300U in our database matches the Core i5-11300H, the Core i7-11375H and also the Ryzen 5 4500U in multi-thread performance, making it an outstandingly good chip as far as sub-US$700 laptops go.

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 3 series chip has a default TDP of 15 W, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing accordingly as a result. By going for the lowest value possible, it will be possible to build a passively cooled system around the chip, however, most companies will do the opposite to achieve higher performance levels.

The AMD Ryzen 3 5300U is built with TSMC's 7 nm manufacturing process for average, as of mid 2023, energy efficiency.

AMD Ryzen 7 3780U

The AMD Ryzen 7 3780U,a Microsoft Surface edition chip, is a mobile SoC that was announced in Oct 2019 as part of the new Surface Laptop 15. It combines four Zen+ cores (8 threads) clocked at 2.3 - 4 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (704 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 Ryzen 7 3700U, the 3780U offers the faster Vega 11 instead of the Vega 10 GPU.

The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPC (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.

Performance

While we have not tested a single system powered by the 3780U as of August 2023, it's safe to expect the chip to be about as fast as the Ryzen 7 3700U, as far as multi-thread performance is concerned.
