Intel Core i5-8265U 8th Gen Quad-Core Laptop CPU

The 8th Generation Intel Core i5-8265U is a mid-range laptop processor. It replaces the widely adopted 8th Gen i5-8250U. Both of these quad-core processors belong to the same 8th Gen Intel Core family, so it’s not surprise they are very similar in terms of specs and performance. The only notable difference is that the 8th Gen i5-8265U “Whiskey Lake” chip offers a higher maximal clock speed “TurboBoost” frequency of 3.9 GHz instead of 3.4 GHz.

Intel Core i5-8265U CPU Benchmark

Intel Core i5-8265U Benchmark

Indeed, the benchmarks show a slight advantage of the i5-8265U over the i5-8250U. But in the real world use, it’s questionable whether you’ll be able to tell the difference at all. Both chips are perfectly suitable for the regular daily computing duties like web browsing, text and spreadsheet processing, video playback, and similar. They also offer a good potential for some heavier stuff like video editing.

As for gaming, the Core i5-8265U features the same integrated graphics processor as the i5-8250U, without change of the specs. It’s the Intel UHD 620 integrated graphics, which is capable of rendering light games and some more demanding titles but on low detail settings. Thanks to the higher clock speed, the i5-8265U can have a slight advantage in some games and gaming scenarios that greatly utilize the main processing cores.

Note: The benchmark scores of the listed processors are averages measured across various devices with these processors. The scores and real-world performance of the Intel Core i5-8265U and compared CPUs may vary depending on the notebooks' other components, settings, cooling, and other factors. However, the benchmark results are good indicators of the processors' performance.

  1. Question

    Hail

    Hi! My laptop came with a DDR4 4GB 2400 mhz 1Rx16 ram, I’m planning to buy the same ram but only in 1Rx8 as it is cheaper. Will mixing 1Rx16 and 1Rx8 ram work or not?

      Yes, combining 16GB and 8GB of compatible RAM does work. I hope your laptop supports more than 16GB RAM. This depends on the laptop’s processor and motherboard.

  2. Question

    Samuel

    Everytime when i run games like Fortnite, Apex Legends. my pc will get very hot. And also the frequency is near the maximum frequency.Can anyone tell me why?
    I use hp pavillion laptop 14-bf1xx
    And my processor is Core i5-8250U with 8GB RAM
    and quad core

      Have you checked for dust blocking ventilation? The heat sink may not be seated correctly. That can happen if the computer have received hits. Can also be faulty from factory. The CPU itself can also be faulty in some way. Have you messed with the hardware settings to overclock something? What surface is under the computer? For instance having it in the bed is very bad. Recommended is a flat surface without any cloth under it.

      How could a CPU that only runs at a despicable I.5 GHz be nothing more than a worthless piece of shit, as horrible as a Pentium 4. Don’t you think that if 1.5 GHz was fast enough, that desktop CPUs would also only run that slow, instead of at 4.5 to 5.0 GHz like they do???????????

      Hi Brad,
      There are a few reasons that the clock speed is so low.
      1. It is a laptop CPU. If it was a desktop CPU, it can afford to be more power hungry and have a faster clock speed. However, battery power is limited in laptops, and it must be slower to consume less power.
      2. Turbo boost
      This chip has turbo boost technology, increasing the clock speed to a more respectable 3.9 GHZ under load. This isn’t 5 GHZ, but it is fast enough to do any modern function. Keep in mind that laptops can get hot if the chips get too hot.

      But that turbo boost technology is trash it can only boost clock speed for a short amount of time under heavy load then the clock maintain at 1.6 GHz giving the thermal throttling

      True, you can also undervolt using softwares such as Throttlestop to get a much more sustained Boost Clock. The i5-8265U has stunning undervolting potential and its possible to be able to sustain at least 3.7GHz while keeping temperatures below 68 degrees C. Benefits? Lower temperatures, improved performance and better battery life. Drawbacks? BSODs due to voltages that are too low for the processors, which again isn’t a big deal as it won’t damage the laptop in any way. The benefits far outweigh the drawbacks.

      Hi, integrated graphics uses a portion of system memory (RAM). It doesn’t have its own memory.

    what is 8265U stands for and why its mentioned near i5 processor

    • Dan

      The important number here is 8, which means it’s the 8th Generation Intel Core processor. 265 isn’t important part, it’s good to know that it is greater than the 250 (of the i5-8250U), meaning the 8265U is a newer model with slightly better specs. What’s also important is the U on the end, which means it’s optimized for the mainstream laptops. There are also for instance Intel Core CPU laptop processor names ending with H, which are used in high-performance, mostly gaming, laptops. And there are Y processor with greatly reduced power consumption in comparison to U, but also with generally lower performance.

    Ordered refurbished Dell inspiron. After replacing single So-dimm with 2 matched So-dimm. Can some one teach Dell about Dual channel memory? Laptop works much better. 10-20% improvement.

    Dear Concern,
    I newly purchased HP Core i5-8265U in June-2019 with Licensed Windows 10 Home, and Installed only two software “MS office 2013” & “Adobe PS CC 2015” but unfortunately unable to use my system because at every stage of work i got memory (RAM) error as well as system is too much slow.

  7. Master3D

    Can I install DirectX 10 on this-
    Intel Core i5 8265U.
    2GB AMD radeon 520 DDR5 graphics.

    Please reply because whenever I want to install DirectX 10, it says, “An internal systen error occured.”

    Please help if you know the solution.

      2GB AMD radeon 520 DDR5 graphics have support for DirectX 10. It even have support for DirectX 12. The error message is due to something else. The anti-virus software might block something. Have you installed all updates from windows?
