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.
The AMD Ryzen 3 7335U is a processor for mid-sized laptops based of the Rembrandt refresh generation. The Ryzen packs four of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 3 (guaranteed base clock) to 4.3 GHz (single core boost) and support SMT / Hyperthreading (8 threads). The 7335U is the first Ryzen 3 based on the Zen 3+ architecture and slowest model of the 7035U series.
The Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip offers modern features, like support for USB 4 (40 Gbps), PCI-E Gen 4 and DDR5-4800MT/s or LPDDR5-6400MT/s.
The performance should be clearly better than the old Ryzen 3 5300U and Ryzen 3 5425U due to the higher clock speed and improved architecture.
The integrated GPU Radeon 660M is still a fast iGPUs based on the RDNA2 architecture and offers 4 of the 12 CUs at up to 1.8 GHz.
The Ryzen 7335U is manufactured in 6nm FinFET at TSMC and specified at a TDP of 28W.
