AMD Ryzen 7 7730U vs AMD Ryzen 5 5625U

AMD Ryzen 7 7730U

The AMD Ryzen 7 7730U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh in early 2023 and offers the same specifications as the old Ryzen 7 5825U. The CPU integrates all eight cores based on the Zen 3 microarchitecture clocked at 2 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in 7nm at TSMC.

The Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2 but stays behind the current Zen 4 based CPUs (e.g. 7040HS series).

Performance

The average 7730U in our database is in the same league as the Ryzen 7 5825U, Ryzen 7 6800U, Ryzen 7 PRO 6850U and also the Core i7-1360P, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the ThinkPad E14 G5-21JSS05C00 is among the fastest laptops built around the 7730U that we know of. It can be almost 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

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.

The TDP of the APU is specified at 15 Watt (the 5825U was specified at 10 - 25W). 

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.
