The 7980XE is a bit of a beast, the CPU alone was pulling over 500 watts when overclocked to 4.4Ghz and rather worryingly was heating up the 24 Pin board cables :O


If you're overclocking that have one of these at your side.

I'm made up TBH. Pushing the power envelope to deliver the maximum performance should be encouraged. It a bit of shame it will take the price of a new car to make the most of it but at least we now have the option.

Competition, its pushed Intel to become this drastic, not that long ago Intel was singing the tree-huggers tunes, thats now gone completely out of the window to hold off a very effective attack from AMD.
Intel are having to throw everything they have at it, climate conscientious CPU's? no not now... Dirty Coal, Ice-Bergs, Polar Bears and diced Dolphins to power these massive CPU's, whatever it takes to stay ahead of AMD.

just how it should be.

Yeah I susopse so. Intel probably would club a seal to sell a CPU.

Very surprised we haven't seen any push back yet.
 
The silicon lottery has never been so important until now. Imagine how much difference an extra 100MHz across 18c/36t will make to those who can utilise all cores simotaneously. You're effectively losing or gaining 1800MHz (across all cores) for every 100MHz you can squeeze out of the thing.

Perhaps in this context unless Intel start binning properly and adjust the price accordingly silicon has had its day. If you're spending 2K on a CPU alone, chance and luck shouldn't have anything to do with it.
 
Anandtech review, athough it's being split into 2 parts and the first part focuses on what the chip is aimed at, and normal user tasks and gaming being saved for the second: https://www.anandtech.com/show/11839/intel-core-i9-7980xe-and-core-i9-7960x-review

So it beats Threadripper in pretty much most things. There's a couple of scenarios where even the 7700K pulls ahead, probably due to the higher speeds or it could be the new mesh interconnects vs the ring buses. And it seems the mesh could actually bottleneck certain workloads:

While it offers scalability over using rings, it has not had over a decade of optimization, and some users have pointed to the frequency (usually 2.4 GHz) as being a bottleneck in their software over the faster ring design.

You can generally run Intel chips at 4.1-4.2ghz with 1.1V so what wattage they pull at 4.4ghz 1.4V is largely irrelevent unless you're an extreme overclocker in which case you don't really care about power draw in the first place.

They're still incredibly poor value compared to AMD Threadripper though but on the AMD side you have to be concerned about the long term effect of high stock voltages.

Voltages? you're comparing Apples to Oranges, AMD's voltages are completely normal for AMD, if AMD's "higher than Intel" volts caused higher power consumption i could understand your point, but it doesn't, its actually the Intel CPU's with the "lower volts" that have the higher power consumption.
