Ryzen 3 5400U vs Ryzen 5 5500U comparison

In our benchmarks, the Ryzen 3 5400U beats the Ryzen 5 5500U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 5500U in all gaming tests too.

When comparing core counts for these CPUs, we notice that Ryzen 5 5500U has significantly more cores with 4 compared to the Ryzen 3 5400U that has 6. It also has more threads than the Ryzen 3 5400U.

Our database shows that the Ryzen 3 5400U has a slightly higher clock speed than the Ryzen 5 5500U.

Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

In terms of cache, the Ryzen 5 5500U has significantly more L2 cache when compared to the Ryzen 3 5400U. But both these chips have the same amount of L3 cache.

In conclusion, all specs and CPU benchmarks considered, will recommend the Ryzen 3 5400U over the Ryzen 5 5500U.

CPU comparison

Use the table to the left to compare both the Ryzen 3 5400U and the Ryzen 5 5500U, the advantages and disadvantages of each are shown.

CPU rating

Our CPU rating is split into 4 categories: Overall, Gaming, Multitasking and Heavy Workloads. The overall score accesses performance using all CPU cores, gaming prioritises the first six cores, multitasking takes the first eight cores into account and finally heavy workloads are measured using a sixteen-core baseline.

Processor specifications

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Ryzen 3 5400U has more threads than cores. Each physical core is split into multiple threads.

Clock speed and Turbo speed are important when comparing per core performance, generally the higher, the better. A higher clock speed may cause a higher TDP, however.

TDP (Thermal Design Power) is a measurement of how much energy is lost as heat when a processor is running. This has an impact on system temperatures. If temperatures get too high (typically around 100 °C or 200 °F), the CPU will lower its performance in order to prevent damage to the chip. Adequate cooling is essential for good performance.

Cache is very fast memory built into the processor. It stores what the CPU is currently working on and anything that doesn't fit is sent to the main system memory, which is slower but more plentiful. It is split into three levels, with Level 1 being the fastest and Level 3 being the slowest. More CPU cache is desirable for high-performance scenarios.
