AMD Ryzen 3 PRO 4450U

AMD R3 PRO 4450U

The AMD Ryzen 3 PRO 4450U is a processor for thin and light laptops based on the Renoir architecture. The PRO 4450U integrates four cores based on the Zen 2 microarchitecture (quad core CPU). They are clocked at 2.5 (guaranteed base clock) to 3.7 GHz (Turbo) with SMT / Hyperthreading support (8 threads). The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the faster Ryzen 5 4000 CPUs (e.g., Ryzen 5 PRO 4650U), the Ryzen 3 only offers 4 cores and lower Turbo clock speeds.

The PRO processors offer a range of business features like hardware security (e.g., AMD Memory Guard), manageability (e.g., support for Microsoft Endpoint Manager), and longer availability and software stability. 

Thanks to the new Zen 2 cores, the Ryzen 3 4450U should offer a slightly better performance as the Ryzen 5 3500U. For an lower mid-range CPU, the performance is quite good and sufficient for most demanding tasks.

In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 5 integrated graphics card with 5 CUs and up to 1400 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

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