Intel Core i3-8145U 8th Gen Dual-Core Laptop CPU

The 8th Generation Intel Core i3-8145U is on the lower-end of the mid-range 8th Gen Intel Core U laptop processor series. As an updated version of the 8th Gen i3-8130U, the i3-8145U retains the same dual-core design as opposed to quad-core of the i5 and i7. The i3-8145U has a higher clock speed of 3.9 GHz versus 3.4 GHz, which is the only important difference between it and the i3-8130U.

Benchmarks of the Intel Core i3-8145U show its noticeable but not big advantage over the i3-8130U. However, in the real world use the difference won’t be noticeable most of the time. Both processors can easily crunch the usual day-to-day tasks like like web browsing, work on Office documents, video playback, and similar. In more demanding tasks like video editing, advantage of the i3-8145U will be a bit more noticeable. But for these heavier tasks recommended are the quad-core i5 and i7.

The 8th Gen Intel Core U processor series, including the i3-8130U and i3-8145U feature the same integrated graphics processor – the Intel UHD 620. Besides light casual games, it can also support some more demanding titles but on low detail settings, as described in this review of the UHD 620.

    Comparing the Acer Inspire 5 i5 and the Asus Vivobook s15 i3. Both in a fairly close price range. Main uses will for day trading (chrome tabs and possibly one trading app) Do you think the i3 is capable of multi tasking on my entry level usage need?

    I’m planning to buy a new notebook with i3-8145U. I will be working on office documents (mostly excel), multi-tasking like browsing, video streaming and other normal stuff. Will it run smoothly?

    • Dan Z

      Yes, the i3-8145U is a very good processor for the daily computing tasks you mentioned. Choosing the faster Core i5 and i7 versions won’t noticeably improve performance in these light tasks, as opposed to heavier duties like video editing. Just make sure you get at least 8GB of RAM for comfortable multi-tasking.

    Hello, I’m thinking of purchasing a laptop with i3-8145U. I’ll be using the editing software shotcut (which is a basic free one). The laptop also has 8gb and 128 sdd. Do you think this would be sufficiant. The videos i’m editing are not HD. I’m getting conflicting info about whether I should get an i5 processor. Thanks in advance!

      Hi, the i3-8145U is capable of video editing, especially if it isn’t in high resolution. But, the comparable i5(-8265U) would speed up video export / encoding. I haven’t tested the Shotcut app, but I would expect at least 25% faster video exports, roughly.

      Generally, if video editing is the main type of work, I always recommend the i5 over i3. On the other hand, the i3-8145U is a very good processor and I don’t consider it to be a performance bottleneck for the type of video editing you mentioned.
