Excellent performance for mix of PC apps and use 4/1/2020 7:21:40 PM

Pros: Able to handle many open applications while showing low CPU usage, with no noticeable degradation to any of the applications.
Overclocked to 4.6 GHz with basic XMP and manual all core speed setting
"Invisible" in that I never think about having too much running or heat, although I like to look at the values just to see all of the cores working for me!

Cons: Nothing, I haven't seen anything I think is wrong or that I don't like. "Invisible".

Overall Review: I run the gamut of applications each day from spreadsheets to coding to video rendering, several browser tabs active, CCTV monitoring, satellite tracking, satellite telemetry gathering and conversion, 32+ channel outboard audio interface, DAW, nearly 20 COM ports both hardware RS-232 type and USB. It is sweet to be able to just do that without having to close or even minimize applications, just having them available for access multiple times in the day. Three monitors make that easy as far as real estate so this processor lets me take advantage of "desk space".
Most appreciated is the hardware interaction with the audio interface over Thunderbolt and radio hardware through the COM ports. Audio latency is very low and all of the external connections run without a thought. More "invisible".
I like to experiment but I am not a hard core overclocker, mainly because of the time involved to get that ultimate tweak and the chances of a crash while doing so or when pressing the limit that are intolerable because of the amount and bunch o' applications work I do. The 4.6 GHz is smooth since I set it and the temperatures are great, IMO. Again that's not something I follow in detail, the CPU is water cooled and max I've seen in normal use is around 63C, not running any hard synthetic benchmarks since I'm not a speed freak like I said. Idle with several stock apps is 30-35C depending on room temp (usually 76F, more or less) and bouncing up to 40C on some cores when something takes off to do something relatively intensive.
I do close many applications when I game, which is a result of the fact that I game late at night after I do all that work and also to guarantee I'm not hosing myself in the game by having something running that I don't need while I'm gaming, anyway. With VR, Elite: Dangerous and Half-Life: Alyx run smooth and temps are good, at or below 60 (all seen after I take the VR headset off on the monitor history) and the GPU takes a good chunk of that work, of course. So GPU runs no more than 60C as well, the interior temp is good even though the CPU radiator is is using intake fans.
I don't know what else to say, it's a great CPU for varied use and games like a champ, I'm not a hardware fanatic as far as benchmark speed and it overclocked nicely and easily, giving me a bit more base oomph with very little apparent temperature change so I would recommend it if you are doing various things on a PC. If you are looking for a gaming PC the other chips like i9-9900K may be what to look at, if you wanted a dedicated video rendering PC or maybe a CAD software/design PC this may be your ticket. For my use as described, it's the low end of this class of CPU and cores are like shiny things that attract people just by their numbers these days, but the price and performance are very right for the type of use I hopefully described well enough for you to understand in your considerations for your expected use.

Great 14 core i9-9940x 2/23/2020 5:00:44 PM

Pros: Lots of cores. Installed on a asus rog rampage vi extreme omega motherboard with corsair DDR4 4000 dominator platinum memory.

Used corsair H150i pro water cooler to keep the cpu cool.

Cons: Fabricated using 14nm.
L3 cache only 18 megabytes.

Overall Review: I would not purchase this product again.
I would wait for a 7nm CPU.

Awesome Processor 2/19/2020 12:11:08 PM

Pros: This thing is fast, and overclocks very nicely.

Cons: Produces quite a bit of heat and heavy power draw, but you expect that from a 10-Core i9 processor. Strongly recommend a liquid cooler setup.

Overall Review: Solid processor, no problems with settings or overclocking. Does produce a lot of heat under heavy load, even at "normal" speeds, so liquid cooling strongly recommended.

This is a fast processor!! 1/29/2020 5:29:55 PM

Overall Review: I love the I9X CPU, it is fast, has 20 threads and 10 cores. I have not found any program that makes it struggle.

Good 12 core 12/28/2019 9:06:42 AM

Pros: Works fine.

Cons: Cost

Overall Review: I bought this to replace a 7920 that I de-lidded. The de-lid was a fun project and got me a 20 deg drop in temps but I lost 2 memory channels (c and d) so that was a thousand dollar mistake. I like this chip better cause it's clocked higher and runs the same temps as my de-lid 7920. update.... Running fine at 4.5Ghz all core under water. Im happy.
