AMD Ryzen 7 5800
Benchmarks & Specs

The AMD Ryzen 7 5800 is an 8-core desktop processor from AMD. It supports SMT (Simultaneous Multi Threading), also known as Hyper-Threading, and can process up to 16 threads simultaneously. The processor clocks its eight cores with 3.4 GHz in the base and up to 4.0 GHz via turbo. If only one CPU core is used, the processor can increase its clock frequency up to 4.6 GHz.

The CPU cores are based on the "Zen 3" design from AMD, which has achieved an IPC increase of around 20 percent through several optimizations, including in the processors cache area. The level 3 cache is 32 MB, the level 2 cache is 4 MB. AMD combines the caches into a so-called "Smart Cache". Thanks to the efficient 7 nm structure of the processor, it is also very efficient. Like all current AMD processors, the AMD Ryzen 7 5800 is manufactured by the contract manufacturer TSMC.

The processor can address up to 128 GB of DDR4-3200 memory via a maximum of two memory channels (maximum 4 memory modules). By using at least two modules, it is possible to activate the dual-channel mode, which doubles the memory bandwidth.

The AMD Ryzen 7 5800 has 20 PCIe 4.0 lines that run directly over the CPU. This allows, for example, a modern graphics card and a fast M.2 PCIe 4.0 x4 SSD to be connected to the system without the chipset of the mainboard being required. The direct connection of devices to the CPU is minimally faster than the connection via the chipset of the mainboard.

With a TDP of 65 watts, the AMD Ryzen 7 5800 is also suitable for more compact systems with smaller cooling solutions. The processor fits into socket AM4 and can therefore be replaced later. The processor was presented in the second wave of the Zen 3 desktop processors in early 2021.
