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.

    Looking at buying either a new laptop with either i3 8145u or going up to i5, both are relatively similar in price. Needed for mostly college use only, no gaming or photo editing but heavy multi tasking, including large excel files ob top of web browsing, Would i3 dual core be sufficient or is i5 necessary.

      I just bought the i3-8145u the processor is relatively fast. It boots up fast and seems to run programs well. The guy at the store told me it would be slow and that I should buy a better one or get more ram but I only play old games or using the web on it. You can see above this i3-8145U actually is faster than a lot of i5s. You can’t go only by the speed. It has four cores and over clocks at 3.9 gig. They just keep the base speed low because it conserves power on a laptop. Having more cores is also better but I don’t understand it. I just know it works pretty well.

    Hi,

    I’m planning to buy HP 15s-du0093TU i3-8145U 8GB laptop. It will be for official use. The main tasks include using G suite applications like Slides, Sheets, and Docs. Apart from that usual web browsing, email, social media, etc. I don’t play any games.

    Currently, I’m using HP 2000 Notebook PC with i3-2350M, 4GB RAM. I can do all these tasks but face lag sometimes. I’ve replaced HDD with Gigabyte SSD 256 already. Maybe its the age of the laptop (7 years) which is causing the lag.

    For my use case, is HP 15s-du0093TU a good choice or should I go for anything higher?

    Thanks 🙂

      Hi, I don’t think you need any faster processor than the i3-8145U for web-based use you described, including Facebook. And it’s faster than your old i3 for sure.

    Hi, I’m planning on buying intel core i3-8145U, will be using for normal tasks and online campus classes. Is it enough? What’s your recommendation.

    • Dan

      It is optimal for these tasks (like web browsing, web-based apps, email, movie playback and similar) and I don’t think you need anything more powerful, like the Core i5-8xxx or i7-8xxx series. In your case it’s rather smarter to invest in solid state drive storage instead of hard drive storage for a bit higher price. Also, I would get at least 8GB of RAM to make sure there are no slowdowns when you run multiple programs at the same time.

    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!

    • Dan Z

      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.
