The AMD Ryzen 3 PRO 5450U is a processor for thin and light laptops based on the Cezanne generation. The R3 5450U integrates four of the eight cores based on the Zen 3 microarchitecture and is the slowest U-series processor of the Cezanne generation at launch. The cores are clocked at 2.6 (guaranteed base clock) to 4 GHz (Turbo) and support SMT / Hyperthreading (8 threads). The chip is manufactured in the modern 7 nm process at TSMC.
The PRO CPUs offer additional management and security features. The 5450U is otherwise identical to the Ryzen 3 5400U.
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.
Performance
While we have not tested a single system built around the 5450U 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 5450U 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.
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.
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).
The AMD Ryzen 5 5600U, not to be confused with Intel's Core i7-5600U, is a fairly fast Cezanne family processor designed for use in thinner, lighter laptops. The R5 5600U integrates six of the eight cores based on the Zen 3 microarchitecture and is the third fastest U-series processor at launch. The cores are clocked at 2.3 (guaranteed base clock) to 4.2 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
This Ryzen 5 series chip is a solid mid-range CPU, as of early 2022. Its multi-thread benchmark scores nearly match those of the Intel Core i5-11400H (a much more power-hungry hexa-core chip designed for use in gaming laptops). While not nearly as fast as 12th generation Alder Lake-P processors, the 5600U should be good enough for the vast majority of users.
Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the IdeaPad 5 Pro 14ACN6 is among the fastest laptops powered by the 5600U that we know of. It can be more than 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Ryzen 5 has a default TDP of 15 W, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing accordingly as a result. By going for the lowest value possible, it is possible to build a passively cooled system around this chip. Most laptop makers, however, will do the opposite to maximize performance.
The AMD Ryzen 5 5600U is built with TSMC's 7 nm manufacturing process for average, as of mid 2023, energy efficiency.
The AMD Ryzen 7 PRO 5875U is a processor for thin and light laptops based on the Cezanne / Barcelo generation. The R7 5875U integrates all eight cores based on the Zen 3 microarchitecture and is the fastest U-series PRO processor at launch. They are clocked at 2 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT for a total of 16 processing threads. The chip is manufactured on the modern 7 nm TSMC process.
The PRO CPUs offer additional management and security features. The 5875U is the refresh of the Ryzen 7 PRO 5850U and offers 100 MHz higher clocked CPU cores.
The 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.
With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 7 PRO 5875U should be clearly faster than the lower clocked Ryzen 7 4800U.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 graphics processor 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).
