Ryzen 5 5600G vs Core i9-9900K comparison

In our benchmarks, the Core i9-9900K beats the Ryzen 5 5600G in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 5600G in all gaming tests too.

When comparing core counts for these CPUs, we notice that Core i9-9900K has slightly more cores with 6 compared to the Ryzen 5 5600G that has 8. It also has more threads than the Ryzen 5 5600G.

Our database shows that the Ryzen 5 5600G has a slightly higher clock speed than the Core i9-9900K. Despite this, the Core i9-9900K has a slightly higher turbo speed.

A Ryzen 5 5600G CPU outputs less heat than a Core i9-9900K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

In terms of cache, the Ryzen 5 5600G has significantly more L2 cache when compared to the Core i9-9900K. But both these chips have the same amount of L3 cache.

In conclusion, all specs and CPU benchmarks considered, will recommend the Core i9-9900K over the Ryzen 5 5600G.

CPU comparison

Use the table to the left to compare both the Ryzen 5 5600G and the Core i9-9900K, 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 5 5600G 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.
