The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
On August 29, 2022, AMD announced four Zen 4-based Ryzen 7000 series desktop processors. The four Ryzen 7000 processors that were launched on September 27, 2022 consist of the Ryzen 5 7600X, Ryzen 7 7700X, and two Ryzen 9 CPUs: the 7900X and 7950X. The processors feature between 6 and 16 cores. [15]
Common features of Ryzen 1000 desktop CPUs: Socket: AM4. All the CPUs support DDR4-2666 in dual-channel mode.; All the CPUs support 24 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset.

Here they also inform that starting from the 12th generation of their CPUs the term Thermal Design Power (TDP) has been replaced with Processor Base Power (PBP). [28] In a support page dedicated to the Core i7 -7700 processor, Intel defines the TDP as the maximum amount of heat that a processor can produce when running real life applications ...
The vapor chamber was removed on all Spire coolers bundled with Ryzen 3000 CPUs. [4] Wraith Spires are offered in two variants, one with and one without a programmable RGB LED ring. It is usually bundled with Ryzen 5 and Ryzen 7 CPUs and has a rating of 95W TDP. [3] The LED ring variant was discontinued with the Ryzen 3000 launch.
Common features of Ryzen 4000 desktop CPUs: Socket: AM4. All the CPUs support DDR4-3200 in dual-channel mode. L1 cache: 64 KB (32 KB data + 32 KB instruction) per core. L2 cache: 512 KB per core. All the CPUs support 24 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset. No integrated graphics. Fabrication process: TSMC 7FF.
The X370 chipset supports multiple graphics cards. But the number of available PCIe lanes depends on the CPU/APU. Support for Zen (including Zen+, Zen 2 and Zen 3) based family of CPUs and APUs (Ryzen, Athlon), as well as for some A-Series APUs and Athlon X4 CPUs (Bristol Ridge based on the Excavator microarchitecture)
