AMD RYZEN 5 4500U (Renoir architecture)
The AMD 4500U is a mobile APU for thin and light laptops which is based on Renoir architecture. This APU (Accelerated Processing Unit) has six cores based on the Zen 2 microarchitectures. AMD Ryzen 5 4500U cores are clocked at about 2.3 up to 4 GHz using the turbo boost without Hyperthreading support. This chip is manufactured using a 7-nanometer process at Taiwan Semiconductor Manufacturing Company (TSMC). AMD advertises an improved performance of about twice per Watt for the Renoir chips.
With two fewer cores, the Ryzen 5 4500U is slower than the Ryzen 7 4700U and 4800U in multi-threaded workloads. This APU still beat the fastest 15 Watt Ice Lake Intel Core i7-1065G7 which consists of 4 cores, at 3.9 GHz. This is because of the 4 GHz Boost clock, the single-core performance should be similar. In this regard, the Ryzen 5 4500U is a very fast 15 Watt CPU and faster than the old Ryzen 7 3700U.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 built-in GPU card with 6 CUs and up to 1500 MHz. The dual-channel memory controller supports the faster DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache is often found on the chip.
The TDP of the APU is specified at 15 Watt (default) and may be configured from 10 to 25 Watt by the laptop vendor. That means the chip is meant for skinny and lightweight laptops (but with fans).
The AMD Ryzen 5 4500U APU had a Clock Rate of 2300 - 4000 MHz; Level 1 Cache of 384 KB; Level 2 Cache of 3 MB; Level 3 Cache of 8 MB; 6 Cores and 6 Threads; Power Consumption (TDP = Thermal Design Power) of 15 Watts; 7 nm technology; Max. Temperature of 105 °C and built-in GPU called AMD Radeon RX Vega 6 (Ryzen 4000).
It has a PassMark rating of 11162 points.
