That's huge and it would translate into needing to spend a lot more on cooling for the Intel system. The 3950x can still be cooled on air. If the 10900k needs water the cost disparity could easily crest $100. Of course, you could just try to undervolt the 10900k and drop clocks slightly, but then at that point you are giving up the only reason for buying Intel in the first place.
OK, So now I have read the post Chess was referring to. LOL.
So One thing to note, as Steve talks about in that video I posted above, but about a minute or 2 before the Point at which I start it, is that Intel doesn't really define stock, its more of a guidance. So the reason why 2 reviewers could have wildly different power numbers during testing, is because it matters WHEN you took your measurement.
When running the CPU within Intel's Guidance, the CPU will be allowed to boost for a certain amount of time, and when that time is reached, your boost will drop hard, and bring you back down to clocks that keep you within that 125TDP. So if You Test your power at the very beginning of a CBR20 Run, You are likely to see the CPU somewhere around 250-300w, but if you wait until the end of the CBR20 Run once the Turbo has expired, then you are going to find the Power to be right around TDP of 125w.
So this is why it matters at what point the testing was done, and why if you just look at 2 different charts with no context, you can get 2 wildly different impressions.
Because of this power limit, the truth is you could buy this CPU, and put an Air Cooler on it that could cool 125w, and be completely fine. It would be damn toasty, but it would be within spec. Its just if you want to lock in MCE or do an Overclock of your Own, you will MOST DEFINITELY want a better cooler, or you will end up burning up your CPU over time. But if you have no plans to overclock, then don't worry about it. With an Air Cooler you will almost certainly lose out on the TVB Boost, but you will still have a CPU that can game, it just obviously wouldn't be quite as good as the guy with the 360 or 420 AIO Cooler or better.
And to be honest, as someone who runs primarily Ryzen CPU's, this isn't so insanely different from OCing on Ryzen. No Ryzen doesn't burn up near as much, but if you want to All Core Over Clock the 3900x/3950x to the bleeding edge and go for 4.5Ghz all Core, even on a 360mm Cooler she is gonna get toasty under full load. The biggest difference is she doesn't run near as hot when stock, and you have to push her in an all Core Scenario to really get her there. But put an air cooler on her, and under stock conditions she will still boost relatively well, and will not be near as hot as her new competitor.
