AMD Ryzen 7 5825C vs AMD Ryzen 5 5625C

AMD Ryzen 7 5825C

The AMD Ryzen 7 5825C is a processor for Chromebook laptops based on the Cezanne generation. It is part of the "Barcelo" refresh in 2022 and offers 100 MHz higher clocked CPU cores compared to the old Ryzen 7 5800U. The R7 5825C integrates all eight cores based on the Zen 3 microarchitecture and is the fastest U-series processor at launch. They are clocked at 2 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 7 nm TSMC process. The 5825C is the Chromebook version to the identical Ryzen 7 5825U.

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.

The CPU performance should be between the old Ryzen 7 5800U and the new Ryzen 7 6800U (Zen+, 6nm, 4.7 GHz).

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 (default) and can be configured from 10 to 25 Watt by the laptop vendor (most chips are configured higher than 15 Watt). That means the chip is intended for thin and light laptops (but with fans).

AMD Ryzen 5 5625C

The AMD Ryzen 5 5625C is a processor for Chromebooks based on the Cezanne generation. It is part of the "Barcelo" refresh in 2022 and offers 100 MHz higher boost clock for the CPU cores compared to the old Ryzen 5 5600U. The R5 5625C integrates six of the eight cores based on the Zen 3 microarchitecture and is the second fastest C-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.

The performance of the Ryzen 5 5625C should be only slightly above the Ryzen 5 5600U and clearly lower than the new Ryzen 5 6600U (Zen 3+, 4.5 GHz).

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.

The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor (most chips are configured higher than 15 Watt). That means the chip is intended for thin and light laptops (but with fans).
