The Ryzen 7 5800X eight-core CPU has SMT, so it supports 16 threads. It is, therefore, an 8c/16t CPU design. It’s based on the AMD Zen 3 architecture and is manufactured on TSMC7nm. It contains 4MB L2 cache and 32MB L3 cache. It has 1 CCD, 1 IOD. It has a base frequency of 3.8GHz, a maximum boost frequency of 4.7GHz, and 105W TDP.

The Ryzen 7 5800X and Ryzen 7 3700X look identical, as they are both based on AMD AM4 socket platforms. They are identical in size and height, except for the lettering. They are pretty different in TDP, so that you may want a larger cooler with the Ryzen7 5800X. This CPU’s 105W TDP is higher than the Ryzen7 3700X’s 65W TDP. The Ryzen7 5800X runs much hotter.

The Precision Boost Overdrive (or PBO) support is another feature on the Ryzen 5000 series CPUs. This can be enabled in BIOS to increase boost clocks up to +200MHz. As the official overclocking method, we will use PBO on the Ryzen 7/5800X as our overclocking results. These results will be displayed on our graphs under the PBO results.

Precision Boost Overdrive is supported and implemented as designed on AMD Ryzen 3000 Series processors. To match VRM capabilities, PPT, TDC, and EDC limits are automatically increased to correspond with the BIOS parameters specific to the motherboard.

Workloads that might otherwise be thwarted by socket power or current can continue to boost until another limiter is in effect. The AutoOC feature allows users to increase boost up to +200MHz.
