AMD Ryzen 7 7730U vs AMD Ryzen 7 7735U

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 7 7735U

The AMD Ryzen 7 7735U is a processor for mid-sized laptops based of the Rembrandt refresh generation. The R7 7735U integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.7 (guaranteed base clock) to 4.75 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 6 nm TSMC process. Compared to the previous Ryzen 7 6800U, the 7735U offers 50 MHz higher boost clock and a slightly higher TDP of 28W (vs 15-25W).

The Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip offers modern features, like support for USB 4 (40 Gbps), PCI-E Gen 4 and DDR5-4800MT/s or LPDDR5-6400MT/s.

Performance

The average 7735U in our database is in the same league as the Core i7-1270P, Ryzen 5 6600H, Ryzen 7 5825U, Ryzen 7 PRO 6850U, as far as multi-thread benchmark scores are concerned. The chip is absolutely capable of making most consumers happy, as of mid 2023; of course, your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.

The integrated GPU Radeon 680M is still one of the fastest iGPUs (only bested by the new Radeon 780M). It is based on the RDNA2 architecture and offers 12 CUs at up to 2.2 GHz.

The Ryzen 7735U is manufactured in 6nm FinFET at TSMC and specified at a TDP of 28W.
