AMD Ryzen 9 5900HX

The Ryzen 9 5900HX is a 8 core CPU from AMD released in 2021. This chip has a very good overall score at 62% in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 77%. As for multitasking and heavy workloads, the Ryzen 9 5900HX scores 57% and 56% respectively. Indeed, this is a very good rating for very heavy workloads.

The Ryzen 9 5900HX has 8 cores and 16 threads. This CPU makes use of simultaneous multithreading technology to improve performance on parallel tasks. Each physical CPU core is divided into multiple logical processors. This AMD CPU has a clock speed of 3.3 GHz and a turbo speed of 4.6 GHz : a higher clock speed that can be reached when thermals and power delivery allow. This CPU has a locked multiplier, so you are not able to overclock it beyond this frequency.

As for memory, the Ryzen 9 5900HX makes use of DDR4-3200 memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs.

In terms of cache, the Ryzen 9 5900HX has 512 KiB of level 1 cache, 4 MiB of level 2 cache and 16 MiB of level 3 cache. This is a fast memory located close to the processor, which stores copies of frequently used data from main memory.

This CPU has fast connectivity with support for PCI-Express Gen 3. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs.

Power and thermals for the AMD Ryzen 9 5900HX CPU are a TDP (Thermal Design Power) of 45 watts. This measures the amount of heat the processor produces when running at full load. This isn't a measure of power consumption, but it's good estimate.
