4.0 out of 5 stars Great CPU, Slightly Overpriced to it's siblings
Reviewed in the United States on 12 November 2020
Pros - This is a great CPU with Single-core performance that surpasses any intel competitor and multi-core performance that smashes most of the competition.

It's incredibly energy efficient for the performance gains and has great thermals.

*Upgrading from a I5-2500K, everything I can think of doing is smoother and more responsive. Your milage may vary.

Neutral - Does not come with an in box cooler for those of you wondering.
Suprised there wasn't a wraith prism pairing with this 800x generation considering the thermal performance but you'd be better off using am aftermarket cooler regardless.

*Paired mine with a Cooler master ML240RGB and my max load temp was 74°C before stabilizing at 64°C in a case with 'OK' ventilation under max load (CPU-Z stress test). *Only my memory and Infinity fabric were OC'd.

Cons - Now we come to the two elephants in the room.
1. You gotta be lucky to even get the chance to buy one. Whilst this didn't sell out as fast as the 900x and 950x. It did sell out faster than the 600x and I have not seen it back in stock yet. 11/11/20

2. This processor is a little overpriced compared to it's siblings that flank it.
● 5600x has 6C/12T, 35Mb cache and is priced at $299.

● 5800x has 8C/16T, 36Mb cache and is priced at $447?
*2 more cores, 4 more threads and 1 Mb more cache for $150 price increase? Ok.

●5900X 12C/24T, 64Mb cache and is priced at $547.
**4 more cores, 8 more threads and double the cache for $100 more????

TLDR Great CPU, $50 over priced. If you can afford it (or even purchase it in the first place) Buy a 5900x as it's a better value. If not, save a $150 and buy a 5600x. Identical performance in games and not too far off in production work loads.

Reviewed in the United States on 1 December 2020
Great processor. A huge step up for AMD. This should finally start to scare Intel. Is a hot cpu so make sure you pair it with a quality cooler.

For some reason the decided the best way to send a 500 dollar pc part was using a bubble envelope and nothing else. And you can see the result. Hope it works when I finally get my hands on the other parts.

4.0 out of 5 stars 8 Core King - *EDIT* Eco Mode
Reviewed in the United States on 21 November 2020
At the time of writing this CPU has only been 'available' for about 2 weeks and I'll admit I got very lucky in getting one on launch day. Most will probably find this hard to find until demand/supply stabilize but if you're fortunate like me here are some things I have found so far:

This CPU is a top performer at it's tier. There's a plethora of data at this point in benchmarks about the Ryzen 5000 series and they seem to outscore most of the Intel competitors easily, as well as against the previous Ryzen 3000 series line. Personally I don't think this alone is a great reason to buy this product currently but I will expand later on value, my previous setup was an 8700K and I felt this 'worth' the upgrade for me personally. I use it on a near exclusive gaming PC, with some occasional video rendering and I can see improvement across the board. I play most games at 1440p however, and vs my old 8700k I can tell you the performance gain on average is probably less than 5%. In rendering and workstation benchmarks its much more, to be expected with core count increase.

This CPU in my system tends to run HOT. At least hotter than I expected @ 105W TDP. I'm on a MSI Tomahawk x570 with an Arctic Liquid Cooler 2 280mm AIO, and with stock settings stress testing I'm reaching 75 C quickly, sometimes maxing at 85 C depending on the task. I've checked my mounting and I don't think there is an issue. My system is using a Phanteks P500A with high airflow as well. I've found examples of others reporting this as well online, and it seems exclusive to the 5800x currently. I've done some extended stress testing and it doesn't seem to thermal throttle so I'm not too worried, while gaming it peaks around 68 C.

Overall I've had zero stability problems or crashes so far which is better than expected as AMD has been known in recent years as a problematic launch platform with driver/BIOS issues. Hopefully this stays the same!

In terms of value this is probably not worth it to most who are interested. The 5600x is (for now) the value/performance king of the new series and the 5900x has notable advantages for only $100 more. I think there is still fantastic value in the R5 3600 as well, especially since it can be occasionally had for around $175. If the price of the 5800x drops to $400 or less in the future it will be become a much more compelling purchase. Consider that this is also the end of the line (supposedly) for the AM4 platform. I think you can make a reasonable argument for 10th Gen Intel due to a potential next gen upgrade capability but who knows if it will be worth the wait.

TL;DR: Top performer, value questionable, warm running Ryzen CPU. I'm an enthusiast who wanted to buy into this series before we even knew it was capable, most will find this unnecessary for mid-high tier 1440/4k gaming.

*EDIT* - For those who are interested, I've done more temperature and benchmark and found that enabling ECO Mode in AMD Ryzen Master software is a fantastic way to mitigate high temps. It seems to drop the total power draw from 145w (PBO/OC mode enabled) to about 88w, maintains the same Single-Core score in Cinebench and has virtually no effect on gaming. Heavy multi-core workloads suffer to the tune of about 10% i.e. Cinebench, Handbrake encoding, etc. This is now my default setting, I've noticed CPU intense games dip a little, but still higher performing than my old 8700K and temps on average are 20% less. This is now my default setting as odd as that sounds, maintains my fan/pump speeds much lower and therefore quieter and for 90% of the 1440p gaming I see no performance effect. Maybe this will be improved with further BIOS updates but for now this seems to be the safest option.

5.0 out of 5 stars Beast of a CPU
Reviewed in the United States on 26 November 2020
I ordered it about a week back. At the time Amazon had an estimated delivery date of January 10 but it came early on November 21st.

This is a huge upgrade for me and I can notice the difference gaming at 1080p. My old ivy bridge cpu was bottlenecking my graphics card.

Happy to report that temperatures are good. Sitting between 30 to 40 C when idle and rarely going over 60 to 70 when gaming. I’m cooling it with a Noctua NH-U12S.

I was able to OC to 4.9ghz using the auto OC in Ryzen Master. I’m going to try a manual OC once I have more time.

Highly recommend if you’re looking to build now and it fits in your budget/needs. Honestly based on this CPU I recommend any 5000 series AMD CPU that you can get your hands on.
