Pros: i game like 20% of the time on my computer and spend the rest of the time CAD modelling or compiling code. this thing blows those tasks out of the water while still handling 4k gaming like a champ. in fact i can have a game open, 20 chrome tabs open, and a fully lit scene rendering, and still have processor room leftover for compressing yesterday's work
Cons: doesn't actually taste like a chip, the gold pins stabbed me in the mouth. definitely not a good source of vitamin d
Overall Review: intel should just give up, in fact they just did today and admitted that they wont produce a 7nm part until 2022 or later. they got slammed with a 16% price collapse on the stock market. GUESS YA SHOULDN"T HAVE MILKED THE CUSTOMER EH? especially when the competition is producing parts for this cheap and with this much power for not much heat. no longer will i have an expensive space heater in my office. this thing runs cool
Pros: Snappy processer, stays cool and has a low load even when gaming!
Cons: No cons!
Overall Review: Coming from Intel i7, I wasnt sure about going with AMD. My Intel lasted me 8 yrs overclocked at 4.6ghz. But Surprise! This is a great gaming CPU! I dont even see the need to OC this thing. It chews up and spits out everything thrown at it thus far. Stays cool even in turbo, and while gaming. I played Star Citizen in 4K, and this CPU only carries a 30% load using all 8 cores. Great job AMD, im officially a fan!
Pros: Price Speed Familiarity
Cons: none yet
Overall Review: About every 10 years I get the itch to build a desktop from parts. From 1Ghz AMD Thunderbirds to my last build using an AMD Phenom II black edition, I have been using AMD CPU's for my desktop builds. They just work and have so far each lasted 10 years of overclocked 24/7 ontime usage. This new Ryzen 7 3700X is almost on par with my Intel I9 9900 that I have in an Area51 Laptop. It actually beats it in Cinebench R20. This thing is flying through my video encoding and staying quite cool with a Corsair 115I AIO liquid cooler. I was going to use the included wraith prism cooler as it gets good reviews, but my ram is too tall and too close to it. I am glad to see AMD back competitively with Intel. This is good for all of us!
Overall Review: Upgraded from an R5 1600x. Running this chip with a MSI X470 Carbon Motherboard, 8 GB worth of G-Skill Blinged-Out Ram, and an RTX 2080. Did plenty of research before I upgraded and everyone online was saying it won’t make a difference at 1440p (or 4k) and that the GPU is the bottleneck in those cases. I can tell you right now that none of those folks know what the heck they are talking about. I gained 15-25 FPS in my game of choice by just replacing the 1600x with the 3700x. I play racing games and love to look at the replays afterwards. During replays things were getting choppy with the 1600x dropping down to 40fps during some heavy action. I saved one of the replays to use as an fps test to use with FRAPS to log the min, max, and avg FPS. Min was 42, max was 98, avg was 55. By just installing the chip the min went to 59 fps, max went to 117 and the avg was 69. This chip turned a choppy experience into a smooth one but according to the internet it shouldn’t make a difference. Don’t listen to them. I’m running 3440 X 1440p which is ¾ of 4k and more pixels than the standard 2560X1440p which folks said it wouldn’t matter. Smh One more thing, CPU-Z reports a clock of 4.2** (it fluctuates) GHZ out of the box. My R5 1600x wouldn't even overclock to 4.0GHZ
Pros: - Combined 3 dedicated PCs into 1 while giving me more cores than the summation of the 3 for-mention PCs - For objective reviews of this processor, see professional reviews elsewhere online
Cons: - None.
Overall Review: This review is subjective, for an objective review you can see the hundreds of professional reviews for this processor. Why would you ever need a 12 cores with 24 logical threads? This processor has allowed me to combined 3 PCs into 1, which has dramatically cut down on my I.T. management of disparate systems. I used to have a dedicated PC for gaming/compiling, a dedicated PC for video surveillance, and a dedicated HTPC for streaming and archival management. I now do all 3 in 1 without any performance degradation while also enjoying a speed boost because each of these tasks gets a few more logical cores to utilize. I'm very happy with this processor, I've been holding off upgrading for a long time because my 3770K has been an amazing CPU (and is still amazing). The 3900X is the first CPU which has checked all of the boxes that gave me justification for an upgrade.
Pros: Excels at modern gaming titles, it only falls slightly short if you have something like a Nvidia 2080 Ti GPU. 12 threads are more than enough for most workloads. Excellent IPC means it has more processing power per Hz than most if not all Intel chips currently available. Excellent power consumption for the performance.
Cons: Although really negligible, boost clocks falls slightly short of what I expected. PBO doesn't really overclock or increase performance. In a sense, the biggest con could be that this CPU's specifications are right on the limits, and, even though unlocked there is nothing to be gained by overclocking (except instability and more power consumption).
Overall Review: For many years my overclocked Intel 2600K kept up with modern gaming and light workloads, and at first I was hesitant to upgrade to the Ryzen 3600, however I am more than pleased and blown away by the performance increase, which is much more than I expected. My Cinebench R20 scores on the 2600K were 1768 / 356 @ 4.8 Ghz (!) and on the Ryzen 3600 (stock) it is 3627 / 483. I would 10/10 buy this again, purely because it is the best bang for buck processor on the market right now and you can't go wrong with it, no matter what you intend to use it for.
Pros: Priced right, 7nm, great out of box performance, backwards compatible with older AM4 boards
Cons: Toasty when overclocked; can't get over 4.4 Ghz without a lot of additional power.
Overall Review: I was an early adopter of the Ryzen 1000 series, which came with its setbacks, however the 1700 I had been using for a couple of years proved to be a great CPU. The 3000 series with its 50% die shrink was very attractive and being compatible with older AM4 boards like mine made this purchase a no-brainer. Great performance at a good price point and doesn't really need an OC to be competitive with processors that are priced higher. Might not be a great upgrade from 2000 series Zen refresh but I am quite happy with what I've gained over the 1700. This should carry me through and allow me to keep my current hardware for at least another year or two.

Pros: -fast -doubled my core/thread count from my 4790k, staggering performance leap in multi core apps, decent improvement in single core. -relatively cheap for the performance -ABBA bios has sorted out voltage, temperature, fan noise, and most importantly...boost clocks.
Cons: -PBO settings can be a little confusing, but i've been on Intel since my last AMD CPU, an athlon x2 3600. -AM4 mounting bracket.....ARRRRRGH
Overall Review: I've waited a long time for a chip worthy to replace my 4790k. And I've waited a REALLY long time for AMD to come out with a challenger. This chip is it. I have (and never had) any temperature issues using stock cooler (with stock TIM), and I have it in a NZXT H510, on top of an Aorus GTX 1080ti. So, I don't really understand why people are having so many temperature issues. The mounting bracket is a PAIN, so maybe TIM is being messed up during installation. Who knows? All I know is that my idle temp is lower with stock cooler than my 4790k at 4.6 was with an H90 AIO. Load temps are almost identical. So, the cooler works very well. If not, you either got a dud chip (RMA) or you're simply doing it wrong. The ABBA bios released recently has upped my boost clock to 4.45 on 3 cores, and 5 cores are within 30mhz of 4.4, whereas previous bios release only 1 or 2 cores boosted anywhere over 4.3, so big big improvement there. It also smooths out the fan ramping up/down, which indeed was somewhat annoying. It also stabilized my voltages, thereby giving me more stable temps. I agree with a prior poster...just about EVERYONE told me that i would see virtually no improvement over my 4790k at 3440x1440p 100hz. WRONG. WRONG. WRONG. BF5 was pegging my CPU, and my 1080ti was at 65-90ish% usage. Now, cpu is like 35% and my 1080ti is 99% in-game. BIG difference in my minimum frames and the stability of my frame rate. I expect this CPU will last me for at least 5 years before I get the upgrade bug (again)...at which point i can step into a 3950x or maybe even a 4000 series (depends on whether socket stays the same, obviously). Unless Intel answers with a stunner in the next few years. I'll support the superior product, regardless of the label on the box. And this CPU is superior to anything Intel at similar costs, and lines up closely with their flagship 9900k, for the most part, at roughly 70% of the cost. Add to that the efficiency, and it's a slam dunk. All in all, i ABSOLUTELY think this is a worthy successor to my trusty and loved 4790k, which served me so well for many years. And I, for one, am glad to be sporting an AMD chip again. If you're in the same boat, I don't think you will be disappointed. I'm not. NO RAGRETS
