AMD Ryzen 5 8640HS
The Ryzen 5 8640HS is a 6 core CPU from AMD. This chip has a very good overall score with 6405 points in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 9018 points. As for multitasking and heavy workloads, the Ryzen 5 8640HS scores 5593 points and 5403 points respectively. Indeed, this is a very good rating for very heavy workloads.
The Ryzen 5 8640HS has 6 cores and 12 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 3.5 GHz and a turbo speed of 4.9 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 5 8640HS makes use of DDR5 (FP7r2) memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs. Furthermore, this chip can handle up to 2 channels of RAM, a multichannel memory architecture allows for higher data transfer between the CPU and the memory. However, to take advantage of this, you must have enough memory slots filled.
In terms of cache, the Ryzen 5 8640HS has 6 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 4. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs.
Power and thermals for the AMD Ryzen 5 8640HS CPU are a TDP (Thermal Design Power) of 28 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 a good estimate.
