AMD Ryzen 9 4900HS vs AMD Ryzen 3 5300U

AMD Ryzen 9 4900HS

The AMD Ryzen 9 4900HS is a mobile SoC for big laptops based on the Renoir architecture. The 4900HS integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 4.3 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips

According to our information, the Ryzen 9 4900HS is only slightly faster than the Ryzen 7 4800HS. The CPU is clocked 100 MHz (base and boost) higher, but the gains greatly depend on the cooling and TDP settings. Compared to Intel chips, the i9-9980HK top model should be comparable. That means the Ryzen 9 4900HS should be able to handle all demanding tasks and gaming. Compared to the similar named 45W-version, the Ryzen 9 4900H, the 4900HS is differs in 100 MHz boost and 300 MHz base clock.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with most likely 7 CUs. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

The TDP of the APU is specified at 35 Watt (default). That means the chip is intended for big and relatively heavy laptops. The Ryzen 7 4900HS is the 35 Watt version of the R9 4900H with a 10 Watt lower TDP.

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.
