AMD Ryzen 5000 series Desktop processors are fast, but they’re not: the 105W TDP (thermal design power) for most chips rules them out for smaller, more efficient PCs. It won’t be a problem for a long time, at least. AMD unveiled non-X Ryzen 7 5800 and Ryzen 9 5900 processors with 65W TDP. They need to fit into smaller desktops (or use less demanding power supplies) while still delivering performance to eight and 12 cores you’d expect.
The company didn’t immediately explain how the chips might differ from the 5800X and 5900X aside from lower power consumption, although they are clearly based on the Zen 3 architecture.
