Good CPU for someone who already has an AMD motherboard for it. However, I saved about $100 by buying an Intel i9-10900 (non-K) CPU. Cinebench 23 score is 15,165 while this AMD CPU is supposed to have 15,245 score (according to CPU Monkey's website). So saving $100 would cost one a bit lower performance and no PCIe 4.0 support.

Saving $100 would also get you a much less power efficient processor which will cost more money over its lifetime.

It's actually the opposite! You will not only save $100 but will also save on electricity, as i9-10900 is a non-K CPU with TDP (PL1) 65W and the AMD 5800X is 105W. Therefore AMD will need more cooling and would require more power, with 2 less cores.

It's not about TDP, it's more about performance per watt. Even if the TDP is lower, it can still use more electricity to perform the same task.

TidalWaveOne is correct. Also the TDP numbers are made up for OEMs to design coolers, not power consumption. See "Power Testing" https://www.gamersnexus.net/hwrev...benchmarks 10900K example but K only adds like 10W at Stock

I don't trust cpumonkey or userbenchmarks. They're so obviously biased that it's comical

Since we're on the topic, where's a good resource to compare power usage for 5600x, 5800x and comparable intel cpus in that performance range? I'm trying to decide between a 5600x or 5800x, or if it's actually better to go Intel... Anyone have opinions?

See "AMD vs Intel CPU Power Consumption and Heat" section at https://www.tomshardware.com/feat...intel-cpus

My opinion.... go AMD for any computer that is going to be used for more than just basic tasks like web browsing.

Wish MicroCenter would move back to Bay Area. RIP Sunnyvale location

If you're ONLY wanting it to game, then you probably wouldn't notice much difference between the two as most of the gaming work is done by the GPU nowaday. If it will also be more intensive work that requires multiple channels/cores, like rendering video or big photo files, then I'd say go with AMD.

I'm a graphic designer and am looking to build a new desktop. I also like gaming and was struggling to decide between the 5600X and 5800X, but am going with the 5800X for the 8-cores, might even consider the 12-core 5900X, that is if GPUs are ever in stock and a semi-normal price again. Until I can secure a GPU, I'm holding off on getting anything else.

This is true ONLY if gaming at high resolutions and lower frame rates. Newer titles also do a very good job at utilizing multiple cores so you will likely be able to eek out a few more frames with the extra cores. Games like CS:GO at high FPS and low resolutions would be CPU bound not GPU bound. Also, any sort of RTS or SIM game would very likely be CPU bound before the GPU became an issue, like CIV or AOE2.

You are correct in saying that if its a GPU bound game and you are playing at high enough resolutions then the difference in 5600x and 5800x doesn't matter that much, but this isn't true for all gaming.

I will say though, even at $429 this CPU is not worth it.... its a very weirdly priced CPU when you compare 5600x and 5900x, buuuuuut this does seem to be the only high core count cpu you can actually constantly get your hands on from AMD. I think at $400 this would make a little more sense for the CPU vs the rest of the stack.
