★★★★★This is the PERFECT processor/best value for basic productive work!
How many of you just need a fast processor for standard home/office work? Buy this and call it a day.
If you need something to handle Microsoft Office, any browser (your internet connection matters more), and basic applications, the 12100 is all you need. Loading time is very good. You really don't need amazing graphics to perform any of these tasks. I'm using integrated video and it suits me just fine. My other computer uses the APU on an AMD 5600G and I've never had issues. I paired this CPU with a barebones Gigabyte motherboard (cheapest I could find) and 8GB of DDR4 memory and it rivals my AMD setup for plain tasks.
Don't feel like you need an i5, i7, or even the i3 12400 if you just need an everyday computer for watching videos, doing online banking, or crunching out work material (unless you are editing heavy media). This i3-12100 is the equivalent of a quad core processor from years back. If you are working on virtual machines, doing strong programming, have a million windows open, need to use Adobe Creative Suite to quickly produce and export content, then you may want to consider moving up to a stronger processor. Even so, this one is still pretty good - it will just take longer to complete some things.
I'm overall very happy with this processor and I think most households who have similar requirements will be satisfied. The 12400 did get to $160 at some point so that could be something to look at to future proof a machine since it has six cores (not that I need them right now).

★★★★★Great efficient and power saving CPU
I've been using the Intel Core i3-12100 in my DIY TrueNAS server, and it's proven to be a solid choice. The quad-core performance at 3.30 GHz handles my data storage and retrieval tasks with ease, ensuring smooth and efficient operation. It has made a noticeable difference in my server's responsiveness, especially when dealing with multiple users and simultaneous access to large files. The energy efficiency is also a big plus, helping to keep my power consumption in check.
While it may not be the most powerful processor on the market, it strikes a perfect balance between performance and cost for a home server setup. Overall, the Intel Core i3-12100 has exceeded my expectations and has been a reliable workhorse in my TrueNAS build.

★★★★★I3-12100 Not recommended for gaming but great for office pc
Great processor for office, home, school if you're not gaming or doing production work. for that I give it 5 stars. However, there's guys on YouTube saying this is good for gaming but It's marginal at best. This is basically a traditional I7 like 2nd gen to 7th gen with 4 cores and hyper threading. The core frequency is holding this back, as the all core is only 4.1ghz. Intel doesn't advertise the all core so you subtract 200mhz from the turbo. So you have the 12100, 13100, and 14100. The later having enough frequency for gaming. It turbos to 4.7ghz and the all core should be 4.5. Also don't buy the 12400 because the frequency is only 100mhz faster. The 13400 is a cut down 12600k and costs more. I say get the 12600k. You have all the cores and frequency out of the box, even if you put it on a B660 or B760 motherboard. In fact I want to buy one on black Friday if the price is right. I remember the price last year so hopefully it will be the same or lower.

★★★★★Does not have Iris Xe
I have this installed into an Asrock motherboard. It works great. I was a little misinformed about the built in graphics and thought when I bought it was I was getting Iris Xe, but it's something called UHD. The product description clearly says UHD, so my bad really. Most of the other Intel 12th gen chips with graphics processing have Iris Xe which has many more graphics processing units. For sure the UHD is fine for many things including streaming video. Not sure about 3D gaming, though. Had I know it was UHD and not Iris, I might have saved $30 or so and bought the version without the graphics. On the other hand, I liked the idea of onboard graphics as a backup or alternative. In either case, this i3 runs like a champ compared to the quad core phenom ii based system it's replacing.
I'm not sure it's relevant here but I think I should mention that my Asrock board can't make use of the on board UHD graphics when you set BIOS to legacy mode. You need to use the UEFI mode in order to use the on board graphics. Not sure if that's typical of other boards or board brands. With my Asrock board, you need a discrete graphics card to use the legacy bios mode to boot from an old non-UEFI installation of windows. If that doesn't make sense to you, don't worry about it.

★★★★★Amazing quad-core processor for the price!
This CPU is incredibly fast and is great for browsing the web and YouTube, completing office tasks or schoolwork, and even light to medium gaming. It only has 4 cores but they are so fast that it can compete with other processors like the 5600G. The integrated graphics aren't amazing but they get the job done and have allowed me to run light games like Roblox and Civ VI while I save for a graphics card. The stock cooler is not amazing at cooling but the i3 12100 doesn't take much power so while any new cooler would probably be an improvement, this one has been doing just fine. For anyone building a PC on a budget, I can easily say this is a great CPU. It won't run all the latest games at max settings but since it can be found for so cheap, it makes for a very cost effective processor.
