Comparison of the two processors

The AMD Ryzen 5 5500U is the direct successor to the AMD Ryzen 5 4500U. The improvements of the new mobile processor can be seen in detail in our CPU comparison. But first there is a small disappointment: AMD still relies on the Zen 2 CPU cores already used in the predecessor for the AMD Ryzen 5 5500U. Although the new "Lucienne" APU design brings a few minor improvements compared to the "Renoir" design of the predecessor, it is not the big hit.

The AMD Ryzen 5 5500U has a base clock rate of 2.1 GHz that is slightly lower than the AMD Ryzen 5 4500U. While the 1-core Turbo is still 4.0 GHz, the newer processor can only clock all CPU cores with 3.4 GHz instead of the 3.8 GHz of the AMD Ryzen 5 4500U.

Nevertheless, the AMD Ryzen 5 5500U is around 5 percent (single-core load) or even 25 percent faster than the AMD Ryzen 5 4500U in the end. This is because AMD now allows simultaneous multi-threading for the AMD Ryzen 5 5500U. This means that the 6 CPU cores of the mobile processor can now process 12 threads in parallel. This is particularly helpful with computationally intensive applications.

Both processors can address a maximum of 32 GB RAM of the type DDR4-3200 or LPDDR4-4266. Two memory channels are available for this, which the system also uses in the best case. The AMD Ryzen 5 5500U uses the AMD Radeon 7 Graphics (Renoir) of the previous version, but in a larger configuration. This increases the graphics performance compared to the AMD Ryzen 5 4500U by at least 30 percent.

The AMD Radeon 7 Graphics (Renoir) clocks at 1.8 GHz, has 7 execution units and 448 shaders. The new and free video codec AV1 is unfortunately not yet supported.

Both processors are manufactured in 7 nm and fit into the FP6 socket. The TDP is 15 watts.
