Intel BX80684I38100

Core i3-8100

▲ 674,345 ▼

4 Cores, 4 Threads @3.6GHz, Coffee Lake.
Release date: Q4 2017.

Average Bench: 70.6% (408th of 1468)

Based on 81,392 user benchmarks.  Device: BFEBFBFF000906EB Model: Intel(R) Core(TM) i3-8100 CPU @ 3.60GHz

Intel’s i3-8100 from their 8th generation of Core processors is a mainstream quad-core CPU. It is the entry model of the latest Coffee Lake line up with a clock speed of 3.6 GHz. Previously, i3 Kaby Lake processors had two cores with hyperthreading, but now, i3 Coffee Lake processors have 4 cores and offer much better value for money in terms of dollars per core. With a performance profile that closely matches last years mid range Kaby Lake i5's (the then go-to mid range gaming choice) and a price tag of just $120, the i3-8100 represents excellent value for money. Unfortunately, like all Coffe Lake processors, the i3-8100 does require a new 300-series motherboard even though it shares the same LGA1151 socket as the previous generation of Kaby Lake 200 motherboards. Intel were clearly mindful of AMD's similarly priced quad core Ryzen 3 1200 which achieves very comparable single, and quad-core benchmarks to the i3-8100.  [Oct '17 CPUPro]

A decent little processor. Good for what it is made to do - office work, Internet browsing. Not so great as a gaming CPU, but again it was not made for such tasks. It worked fine with older games, but even with titles such as Valheim it really struggled and was not a pleasant gaming experience. Even with a dedicated GPU finally installed in the same machine, this CPU did not preform well for gaming. Eventually, this CPU was taken out of the workstation/gaming hybrid and was used for a short time in a low population gaming server. Again, it worked well enough, but not as well as was desired. With that said, I still have this CPU, and it is currently the workhorse in my "does this GPU work at the most basic level" and drive cloning machine.

Great 8th gen CPU. First 4 core I3. Nice to have in a medium build. I think go to the i5 9400f to upgrade a little.

Served me well for 3 years, until i upgraded to an i5-9600K to get rid of the bottleneck with my new GTX 1650. Super good performance, but you can get much better CPUs for a cheaper price today, this one is not worth it anymore.

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
