What kind of difference in power draw between these 2 ? Assuming PBO enabled on both.
Thanks

5800x vs 5950x power draw

Very similar in the 110W region at stock
When both are stock they are fairly similar, about 10w difference between them.
PBO is a totally different beast though, the 5950x can pull up to 270w with PBO enabled and depending on the settings you use and the 5800x can get up to 190w with the same settings.

Some good articles here show how it works across chips:

And how power at the wall (total system power not just CPU power) can go right out of the efficiency windows with PBO for a small gain in performance as the CPU's are already into their inefficient range with the standard 'out of the box' boost practrice:

At base speeds without any boost, you can knock off 50W at the wall with a 5950x and they become very efficient. But efficiency can be boring unless you're folding at home on a CPU or running a server. Personally PBO plus offset lower voltage or just the out of ther box settings are the best for general use if you don't want to mess with CCX and optimizer curves. Manual overclocks use too much power, but have better multi-core performace.
The 105W TDP and 65W TDP are confusing and misleading as they're just heat ratings for CPU coolers to use to hit some ok performace numbers printed on the retail box.
