AMD Ryzen 9 8945HX
The Ryzen 9 8945HX is a 16 core CPU from AMD released in 2025. This chip has a very good overall score with 8535 points in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 8107 points. As for multitasking and heavy workloads, the Ryzen 9 8945HX scores 8825 points and 9118 points respectively. Indeed, this is a very good rating for very heavy workloads.
The Ryzen 9 8945HX has 16 cores and 32 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 2.5 GHz and a turbo speed of 5.4 GHz : a higher clock speed that can be reached when thermals and power delivery allow. This CPU has an unlocked multiplier and allows for overclocking. With adequate cooling and a good power supply, it's possible to run this CPU at a higher clock speed.
As for memory, the Ryzen 9 8945HX makes use of DDR5 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 9 8945HX has 1024 KiB of level 1 cache, 16 MiB of level 2 cache and 64 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 5. 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 8945HX CPU are a TDP (Thermal Design Power) of 55 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.
