Ryzen 9 5950X and 5900X Power Consumption, Efficiency, Thermals
Notably, AMD's decision to stick with the AM4 socket still constrains its maximum power consumption to 142W, which means that the company could not increase power consumption for the new flagship models. However, Zen 3's IPC gains allow the Ryzen 5000 chips to stay within the same TDP thermal and electrical ranges as the Ryzen 3000 series CPUs while delivering more performance.
But there's a bit of nuance to the power story, though. As we can see in the AIDA power measurements, both the 5900X and 5950X draw slightly more power under load than their previous-gen counterparts. However, flipping to the 'renders per day per watt' charts shows that the chips are considerably more power-efficient than the Ryzen 3000 processors, meaning they deliver considerably more performance per watt.
Intel's chips are rather inefficient in comparison, which is a natural byproduct of using the older and less-dense 14nm node. Intel has also turned the dial up on the voltage/frequency curve to remain competitive, which also throws efficiency out the window in exchange for higher performance.
The net-net is that the Ryzen 5000 processors will draw far less power per unit of work than any of Intel's 14nm chips, thus resulting in a cooler and quieter system.
Here, we take a slightly different look at power consumption by calculating the cumulative amount of energy required to perform an x264 and x265 HandBrake workload, respectively. We plot this 'task energy' value in Kilojoules on the left side of the chart.
These workloads are comprised of a fixed amount of work, so we can plot the task energy against the time required to finish the job (bottom axis), thus generating a really useful power chart. Bear in mind that faster compute times, and lower task energy requirements, are ideal.
This measure really separates the wheat from the chaff, and the best results fall to the lower left-hand corner of the chart. The Intel chips populate the less-desirable upper right-hand side. Although the Core i9-10980XE makes a valiant attempt to get down to Ryzen territory, it still can't match the previous-gen Ryzen 3000 processors in terms of efficiency. Meanwhile, the Ryzen 5000 series leverages the Zen 3 architecture to great effect and falls further inside the performance-per-watt sweet spot, marking a new level of efficiency for a modern desktop chip.

Reposting a three week old review?
As a home building enthusiast (for the last decade or so) this is a very exciting time having legit competition between team red and team blue. Even AMD and Nvidia is getting interesting! A fantastic time to be a home builder. I can't wait to see how intel counter punches here. Should be an interesting decade ahead.
But can it break the "be actually in stock" barrier ?
Which benchmark tools give us those results ?
I mean ... It does look cute somewhere in the fluffy land of benchmarks and future upcoming products even though "technically" its not a future product.
aaannnnd it's gone again. LOL
They also probably have limited ability to greatly increase production since TSMC is booked up so they aren't going to increase the volume sold by lowering prices.
It also humorous how fanboys cried at Intel "robbing" "price gauging" but now that their master AMD is showing to be as anti consumer, even more so with GPU fanboys defend what they were crying about before. They are both corporates, sorry I hope it won't come as a shook to you :)
It must be sad being a fanboys of a brand making silicon chip...like really sad. Consumer excited by their masters charging more, imagine if Intel or Nvidia or ATI, or S3 or any tech company charged £50 more each generation, a CPU or GPU or Monitor would cost you ehmmm £50k circa if we start from 8086 onwards... I mean guys if you have no economics basis and your jobs do not involve finance perhaps you should not comment :)
Remember the time Intel's flagship chip was like $1,400/USD? And intel fanboys cried and fawned in the glory of it's brilliance.
Now AMD has a chip that's more powerful that that, that's still listed for about half of what that intel chip was and it's "price gouging" :ROFLMAO::ROFLMAO::ROFLMAO:
Fanboys of any brand are obnoxious. As an end point consumer, I'm just happy to see actual legit competition between the major CPU and GPU communities.
