AMD Ryzen 3 5400U vs AMD Ryzen 7 5800U

AMD Ryzen 3 5400U

► remove from comparison AMD R3 5400U

The AMD Ryzen 3 5400U is a processor for thin and light laptops based on the Cezanne generation. The R3 5400U integrates four of the eight cores based on the Zen 3 microarchitecture and is the slowest U-series processor of the Cezanne generation at launch. The cores are clocked at 2.6 (guaranteed base clock) to 4 GHz (Turbo) and support SMT / Hyperthreading (8 threads). The chip is manufactured in the modern 7 nm process at TSMC.

The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.

With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 3 5400U should be clearly faster than the lower clocked Ryzen 3 4300U.

In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card with 6 CUs and up to 1600 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache (same as the old 4800U) can be found on the chip.

Power consumption

This Ryzen 3 has a default TDP (also known as the long-term power limit) of 15 W. Laptop manufacturers are free to change that value to anything between 10 W and 25 W if so desired, with clock speeds and performance changing correspondingly. Those values aren't low enough to allow for passively cooled designs.

This is a 7 nm chip; it thus has higher-than-average, as of late 2022, energy efficiency.

AMD Ryzen 7 5800U

► remove from comparison AMD R7 5800U

The AMD Ryzen 7 5800U is a processor for thin and light laptops based on the Cezanne generation. The R7 5800U integrates all eight cores based on the Zen 3 microarchitecture and is the fastest U-series processor at launch. They are clocked at 1.9 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 7 nm TSMC process.

The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

Performance

The average 5800U in our database matches Intel Core i5-11260H and, perhaps a little disappointingly, AMD Ryzen 7 4800U in multi-core performance, making it a good option for quality laptops of the thinner, lighter kind but not a must-upgrade.

Power consumption

This Ryzen 7 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 10 W and 25 W with clock speeds and performance changing correspondingly. The 7 nm TSMC process Ryzen 7 5800U is built with makes for above average energy efficiency.
