A nice chart: shows just how great the Sky Lake uArch is as it's been able to compete successfully for five years in a row with almost zero underlying changes (aside from the number of cores/frequencies and microarchitectural tweaks to fix HW vulnerabilities like Meltdown). Thanks! Also puts to rest the claims that the Ryzen 5000 series is universally faster than ages old Sky Lake.another Spec bench in zhihu by Edison Chen

More than.Is a Noctua NH-U12A adequate for cooling a Ryzen 5800x? I purchased this cooler about 2 weeks ago to be installed in my next rig.
I don't know a single person who runs power viruses 7x24.The 5800X runs pretty hot in all-core workloads due to 142W PPT being spread across 8 cores. I'm not sure if the NH-U12A is going to be enough.
It's because both 5600X and 5800X are overpriced junk in terms of performance per dollar - and this is where AMD has lost their mind. Many-cores CPUs should be a lot more expensive per core because they are used by professionals who actually can recuperate their cost.Quite happy with my decision to buy a 5900X. Out of the too three Ryzens, it definitely looks like it offers the best perf/value ratio if you plan to keep using your build for a long time.
This time around both 5600X and 5800X are absolute worst in this regard.
What a win against a five years old uArch running on a much inferior node! Congrats! AMD fans should celebrate it until the rest of their lives. What next, should we compare Ryzen 5000 to Sandy Bridge CPUs for good measure? Alright! An amazing win!Eye watering MT performance as well.

It must take a lot of effort to find tasks which are going to be seriously affected by running on two CCX'es simultaneously. 5800X defeats 5900X in certain scenarios but by a very small margin, however if you're going to run truly parallelized tasks like rendering, video encoding, compilation, AI - then obviously 5900X will be a much better choice not to mention it costs less than 5800x in terms of price per core.Eye watering MT performance as well.

Also 5900X runs quite cooler than 5800X:
So, if I had the money I'd buy the 5900X in an instant however given the new pricing policy I'm not touching Ryzen 5000 until prices go down and there's a sale. Besides I'm waiting for 5700X regardless - I've no desire to put a 142W CPU in my case.
