Pros: Easy to install

Looking to speed up your pc! Get a cpu!!!

What a leap in performance. Came from an i5 to Ryzen. This is great! 4/8/2020 11:48:13 AM

Pros: Fast
Great OC performance
Stock CPU fan is ok

Overall Review: Would recommend this for your next upgrade. I cam from a 4 year old i5 and this is an amazing upgrade. Performance in games has been impressive. Smooth transition too. Just swapped MOBO's and ram and I'm back in action.

Great 4/8/2020 10:58:49 AM

Pros: Great core and thread count great frequency and better performance for a lower price than intel! Great stock rgb cooler!

Cons: DO NOT USE THE STOCK THERMAL PASTE!
Sorry for caps but I have a 3950 x and I used the stock paste from the cooler that came with the 3800x and it ripped out my cpu from the socket when I took off the cooler. I mean come on amd! If you buy this invest ito some thermal paste it’s a few dollars.

Overall Review: Great!

Greta CPU 4/7/2020 2:36:27 PM

Pros: I purchasec this CPU as a replacement for my Ryzen 7 1800X. I noticed a great performance increase, very much so for gaming. Yes, the 1800X is a good CPU. But, the 3800X is so much more. And, yes as AMD promised, the 3800X is supported by the Crosshair VI hero. I am eventually going to get an updated motherboard. But, it works great in the one I have now.

Cons: You don't get PCI-e 4 with using a previous generation motherboard. However, still get great performance.

Overall Review: Very satisfied

The Budget Gaming Choice 4/7/2020 1:54:40 PM

Pros: -Performance to Cost ratio

Cons: -Check your motherboard compatibility (and whether you need updated drivers)
-Cooler is meh

Overall Review: You're almost certainly here reading this review because you want to make the best dollar to fps choice. Pair this with a strong video card and some fast ram and you're going to be playing Doom Eternal/etc (dating the review I guess) at a frame rate that even the snobs are going to be satisfied with. Realistically, it's going to be tough for this processor to be your bottleneck in any realistic scenario where you are contemplating purchasing it in the first place.

Incredibly fast and stock cooler is quiet 4/7/2020 12:34:56 PM

Pros: - Price for performance
- Stock cooler is sufficient to cool under load
- Boosts up for gaming

Cons: - Somewhat finicky on startup with the motherboard I chose with it

Overall Review: The CPU is fast and perfectly adequate for gaming (I mostly use it for VR games) and the stock cooler keeps it cool and quiet even for long gaming sessions. I probably don’t even come close to stressing it on a day to day basis, though but nice to have that headroom. On startup with the Gigabyte X570 UD motherboard it does seem to take longer than I’m used to to post, but other than that it’s been stable.

Stunning. Quality engineering. 4/7/2020 11:34:34 AM

Pros: Fast, low temp, will handle pretty much anything you throw at it.

Cons: None that I've found.

Overall Review: For the price/power point, look no further. This is an amazing CPU capable of handling loads of tasks. If you want something built well, doesn't break your wallet, and gives you the performance you're looking for whether it's to play new AAA games or video editing, you've found your CPU. 10/10, put this in your PC and be a happy person.
