AMD Ryzen 7 5825C vs AMD Ryzen 3 5425U vs AMD Ryzen 3 5125C
AMD Ryzen 7 5825C
► remove from comparisonThe 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 3 5425U
► remove from comparisonThe 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 3 5125C
► remove from comparisonThe AMD Ryzen 3 5125C is a processor for Chromebooks based on the Cezanne generation. It is part of the "Barcelo" refresh in 2022 and is the slowest version of the Ryzen 5000C series at launch. The R3 5125C integrates two of the eight cores based on the Zen 3 microarchitecture. The cores are clocked at 3 GHz (no Turbo) and support SMT / Hyperthreading (4 threads). The chip is manufactured in the 7 nm process at TSMC.
In addition to the two CPU cores, the APU also integrates a Radeon RX Vega 3 integrated graphics card with 3 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.
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).
