AMD Ryzen 5 7430U vs AMD Ryzen 3 5425U vs AMD Ryzen 5 5625U

AMD Ryzen 5 7430U

The AMD Ryzen 5 7430U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh and was announced in Q4 2023. The processor is identical to the old AMD Ryzen 5 5625U.

The SoC integrates six of the eight cores based on the Zen 3 microarchitecture that are clocked at 2.3 (guaranteed base clock) to 4.3 GHz (Turbo) and support SMT for a total of 12 threads. The chip is manufactured on the older 7 nm TSMC process.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card (now only called Radeon Graphics) with 7 CUs at up to 1800 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 performance is identical to the old Ryzen 5625U and therefore in the lower mid range of laptop CPUs in late 2023.

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

This Ryzen has a default TDP of 15 W (also known as the Power Limit 1). Which is a little too high to allow for passively cooled designs.

AMD Ryzen 3 5425U

The AMD Ryzen 3 5425U is a processor for thin and light laptops based on the Cezanne generation. It is part of the "Barcelo" refresh in early 2022 and offers 100 MHz higher clocked CPU cores compared to the old Ryzen 3 5400U. The R3 5425U integrates four of the eight cores based on the Zen 3 microarchitecture and is the slowest U-series processor of the Barcelo refresh at launch. The cores are clocked at 2.7 (guaranteed base clock) to 4.1 GHz (Turbo) and support SMT / Hyperthreading (8 threads). The chip is manufactured in the 7 nm process at TSMC.

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.

Performance

While we have not tested a single system built around the 5425U as of August 2023, we are fairly confident the chip is a little faster than the Ryzen 3 5300U and its four Zen 2 cores running at clock speeds similar to what the 5425U has. Naturally, your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.

Power consumption

This Ryzen 3 has a default TDP (also known as the long-term power limit) of 15 W. Which is fairly low - yet not low enough to allow for passively cooled designs.

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

AMD Ryzen 5 5625U

The AMD Ryzen 5 5625U is a processor for thin and light laptops based on the Cezanne generation. It is part of the "Barcelo" refresh in early 2022 and offers 100 MHz higher boost clock for the CPU cores compared to the old Ryzen 5 5600U. The R5 5625U integrates six of the eight cores based on the Zen 3 microarchitecture and is the third fastest U-5000-series processor at launch. The cores are clocked at 2.3 (guaranteed base clock) to 4.3 GHz (Turbo) and support SMT for a total of 12 threads. The chip is manufactured on the modern 7 nm TSMC process.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with 7 CUs at up to 1800 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 5625U in our database is in the same league as the Core i5-1255U, Core i5-1335U, Core i5-1345U and also the Ryzen 5 7530U, as far as multi-thread benchmark scores are concerned. This is a decent result, as of Q3 2023.

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

This Ryzen has a default TDP of 15 W (also known as the Power Limit 1). Which is a little too high to allow for passively cooled designs.

The APU is built with TSMC's 7 nm process for higher-than-average, as of mid-2022, energy efficiency.
