AMD Ryzen 3 4300U

The AMD Ryzen 3 4300U is a processor for thin and light laptops based on the Renoir family. The 4300U integrates four cores based on the Zen 2 microarchitecture (quad core CPU). They are clocked at 2.7 (guaranteed base clock) to 3.7 GHz (Turbo) without SMT / Hyperthreading support (4 threads). The chip is manufactured on the modern 7 nm TSMC process and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the faster Ryzen 5 4000 CPUs (e.g., Ryzen 5 4600U), the Ryzen 3 only offers 4 cores and lower Turbo clock speeds.

In addition to the four CPU cores, the APU also has the Radeon RX Vega 5 integrated graphics card with 5 CUs and up to 1400 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 4 MB of Level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

Performance

The average 4300U in our database matches Intel Core i5-1035G4 and Core i5-11300H, both noticeably more power-hungry quad-core processors, in multi-thread performance. Technically a lower mid-range CPU, this Ryzen is light years ahead of Intel Pentiums and AMD Athlons that so many sub-US$500 laptops have.

Power consumption

The Ryzen 3 series chip has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are free to change to anything between 10 W and 25 W with performance and clock speeds changing accordingly as a result. By going for the lowest value, it is possible to build passively cooled tablets, laptops, mini-PCs around this APU.

The 7 nm TSMC process the Ryzen 3 4300U is manufactured on makes for average, as of mid 2023, energy efficiency.
