AMD Ryzen 3 PRO 5450U vs AMD Ryzen 5 PRO 5675U

AMD Ryzen 3 PRO 5450U

► remove from comparison AMD R3 PRO 5450U

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).

AMD Ryzen 5 PRO 5675U

► remove from comparison AMD R5 PRO 5675U

The AMD Ryzen 5 PRO 5675U is a processor for thin and light laptops based on the Cezanne / Barcelo generation. The R5 5675U integrates six of the eight cores based on the Zen 3 microarchitecture. The cores are clocked at 2.3 (guaranteed base clock) to 4.3 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured in the modern 7 nm process at TSMC.

The PRO CPUs offer additional management and security features. The 5675U is the refresh of the Ryzen 5 Pro 5650U and offers a 100 MHz higher boost speed.

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 5 PRO 5675U should be clearly faster than the lower clocked Ryzen 5 4500U.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with 7 CUs and up to 1800 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 12 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).
