The core i9 13900k has better performance than ryzen 9 7950x. and this site shows the core i9 13900k turbo boost frequency is 5.4ghz but the core i9 13900k turbo boost frequency is 5.8ghz.

What about the price? The AMD is not worth it. Intel also has more performance, and you can underclock it and lose only a tiny bit.

Are you sure about that?? This site shows test results that 13900K loses more performance than 7950X in lower TDPs. 7950X could still perform up to almost 50% at 35 watts and 80% at 65 watts while 13900K could only maintain 50% performance at 65 watts https://www.anandtech.com/show/17641/lighter-touch-cpu-power-scaling-13900k-7950x/4

Intel can't compete with AMD in terms of efficiency mainly because they make their own CPUs, while AMD gets them manufactured by TSMC...

just undervolt your 7950X by setting "All Core Curve Optimizer Magnitude" to Negative 10 or Negative 15 and overclock it by 150 or 250 MHz and set PBO on. it will drop your temps by 20C and reduces power consumption by a lot and increase your game fps by a lot.

Ummm... Sadly this review is pretty false. Not being a great fan of Intel cpus, I must say that i9 13900K has more raw power than 7950x. And it's not just one site like the other people have to see the wrong result, but it is actually a fact, not a lie. Intel did really push themselves with their 12th and 13h Gen processor and I'm glad to see them back in the spotlight. And on another note, nanoreview is not providing accurate results and I expect some kind of falsehood in this. I was able to detect the same problem with the comparison of 2 smartphone chipsets, one from snapdragon and another from MediaTek. The snapdragon chipset showed major superiority even though other sites did show varying results. Nanoreview shouldn't let down its users like this. Provide accurate numbers. Pls.

First of all, I'm not a fan of Intel. AMD has been making fun of Intel chips for such a long time that they have finally improved. Like this test man. Unfortunately is incorrect. We need to appreciate someone in case they have outdone the best.

Weird comparison. Intel is using P cores and E cores, more total cores but less real powerful cores (16 for AMD and only 8 for Intel)... it's a desktop CPU. Power efficiency, when playing or using the CPU the AMD will reach 230W max, the max on the Intel is 350W for the unlimited mode and 250W for the limited mode... so unless you are not using your computer, AMD is better. According to Anandtech the 7950X is 0.56 TFLOPS (all details to complete the article on their review)

Why does it matter that it has two different types of cores? For tasks like gaming or Photoshop, 8 powerful cores are more than enough. For multithreaded tasks like video editing, the program can take advantage of both types of cores, and Intel has more total cores (24 vs 16), which offsets the lower number of high-performance cores. TDP has nothing to do with power efficiency. I can't find numbers with power consumption while browsing the web, but idle power consumption on an i9-12900k is 8 watts (so maybe 10-12 watts on the 13900K), while on the Ryzen 9 7950X it's 30 watts. Gamer's Nexus also has the Ryzen 9 7950X drawing over 250 watts, so the 230 watts is clearly not a hard limit. I'm not saying the 13900K is more power efficient in all tasks, but your statement is misleading. I would also not trust the Cinebench scores, as the i9-12900K consistently scores over 2000 points without OC, while this is showing 1918 for the 13900K, which is supposed to have a 13% single-threaded gain over the 12900K.

According to AMD, the 90/95°C temperature is "normal" it's the optimal temperature for those CPUs. Basically, the CPU will reach easily above 90°C then if your power supply delivers enough and if your liquid cooling is efficient then the CPU will increase its the frequency (will still stay at 95°C). If not enough power or bad liquid cooling then the same temperature but lower frequency and throttling (not stable in frequency).

Broski, it's the wattage that matters when it comes to how much heat your CPU will radiate, not the specific temperature of the CPU. This a common misconception, but it's true.

So I own a 7950X with a 360 AIO. It idles around 25-30 degrees. When gaming it doesn’t go above 60-70 and under stress tests like cinebench is the only time I see it hitting 95. So this whole 95 thermal limit is a joke.

This information for the power draw is incorrect. It's based on the manufacturer's claimed TDP. If you look at 13900k power draw it is sustaining 270 Watts stock boost and 340Watts when power limits are removed in current benchmark leaks using an engineering sample. In the leaks, which were presumably with a different chip to the one used above. The stock gave a cinebench score of 34000 and the unlimited gave 40000.
