Wicked fast processor 6/3/2020 7:07:27 PM

Pros: Speedy
Insane speed
Can do whatever I want without breaking a sweat

Cons: Absolutely nothing at all, I cannot be any more ecstatic than I am now about a processor.
The only thing I can think of to complain about is the unsuitable stock cooler. Never ever use the fan that comes with it, get a nice cool master or comparable fan. That one can be a pain to install and may not keep it cool enough a serious gamer

Overall Review: Where to begin. it installed without any trouble and has all 6 cores running at perfect unison without any overclock or anything done to it like the champion it is. It's done whatever I asked of it gleefully and without slowing down. I paired it with a Cooler Master Hyper 212 EVO - CPU Cooler with 120mm PWM Fan and cannot be happier. I am getting another fan for it to maximize cooling.

High Performance CPU 6/2/2020 6:34:51 AM

Pros: - Runs every game at high frame rates.
- Makes a great workstation PC too.

Cons: - Included stock cooler seem inadequate.
- Will run hot under heavy load with said cooler.

Overall Review: First, ensure you install a fresh copy of your OS! I cannot stress this enough. Some chipsets you can get away with skipping this. Doesn't seem to be the case with this 9th gen.

Overall a highly recommended CPU. As I spend more time working from home I decided to invest more into my home desktop and create a gaming/workstation machine. This chip seems to handle both of these tasks with ease. It doesn't have hyperthreading, but that it not something I required anyway. More cores and threads isn't always the answer.

Uninformed review 5/30/2020 4:56:49 PM

Pros: Wish I could give 4.5 eggs . . . This processor features the Turbo ability that my last processor did not have (8th gen i3). It passed a short stress test and seems to be pretty solid. This upgrade from 8th gen was made when son's games would lock up and he'd have to restart game (not cpu). He's using a GTX 650, which I didn't think was the problem, but now I'm not sure if we've just been using underachieving processors or if the card is the problem. Using stock cpu cooler but temps don't seem to be getting out of control. A GTX 1660 is on the way, so that should answer it. I'll try to get back and amend review.

Cons: See above . . . I think I was expecting gaming performance from this, but it seems it's not built for that. Maybe a 6th or 7th gen i5 or i7 would have been a more appropriate option for budget gaming. Back when the multi-core era began, it became evident that the more desireable chips were those with higher clock speeds, not necessarily more cores (IE dual core @ 3.4 GHz performed better than quad core @ 3.0 GHz. This was due mainly to the fact that few applications and games were able to utilize multi cores.

Overall Review: I would definitely recommend this to anybody whose primary need is not multi-thread-based computing/gaming. I think video production and processing may run ok with the right video card, RAM, etc.

Well now...! 5/21/2020 10:14:21 PM

Pros: DON'T FORGET NO GRAPHICS: This was so easy that I really don't know what to say! To bad there is not more reviews I guess
Planted this lil jem atop a Asrock B-365 pro4, Intel M.2SSDPEKNW512G8X1, Sapphire RX 570 4 gig
2 sticks of Gskill 8megs of ram 2400 and POOF, it lives! (forgot to set ram speed) fixed that!
Took about an hour, start to finish to install, update and put my software onto the M.2
Very happy with the performance.

Cons: No cons, just had to wait for shipping, No graphics is not a con, never had them, why start!

Overall Review: This replaced my forever running Asus M5A97-R2.0 and AMD 8320 FX that's now retired to the Box it was shipped in.
This little unit backs my Skylake 6700K that still holds on with everyday use also.
Runs cool mid 40"s and fast, works on everything that I have, work from home, Netflix, Hulu , a little gaming, such as No man's sky
Astroneer, World of warships, and so on.
I have NO REGRETS BUYING THIS CHIP, very happy with it.
