AMD Ryzen 9 7945HX3D

The Ryzen 9 7945HX3D is a 16 core CPU from AMD released in 2023. This chip has an amazing overall score with 11621 points in our CPU benchmark. Our gaming benchmark shows that this CPU is an amazing processor for gaming, with a score of 10251 points. As for multitasking and heavy workloads, the Ryzen 9 7945HX3D scores 12118 points and 12323 points respectively. Indeed, this is an incredible rating for very heavy workloads.

The Ryzen 9 7945HX3D 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 2.3 GHz and a turbo speed of 5.4 GHz : a higher clock speed that can be reached when thermals and power delivery allow.

As for memory, the Ryzen 9 7945HX3D 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 7945HX3D has 1024 KiB of level 1 cache, 16 MiB of level 2 cache and 192 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 7945HX3D 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.
