Intel Core i3-7350K Processor Review

Core i3-7350K Kaby Lake Overclocking

To overclock the Intel Core i3-7350K Kaby Lake processor we used the Gigabyte Aorus Z270X-UD5 motherboard and simply increased the multiplier and core voltage until we hit a wall. That wall on this particular board, processor and UEFI version just happened to be at 5,100 MHz or 5.1 GHz, which is pretty impressive. We’ve saw a demo at CES 2017 where Intel was running a Core i3-7350K under a comparable water cooler and only reached 5.0 GHz with more voltage, so we are pretty happy with our overclock.

Intel Core i3-7350K Overclock

To get the Intel Core i3-7350K Processor up to 5.1 GHz we increased the CPU core voltage to 1.40V and the multiplier up to 51x and that is it. Overclocking was very simple and you can really tell a difference between the system running at 4.2 GHz and 5.1 GHz.

With the CPU core voltage set to 1.40V we were seeing 1.38V under full load in AIDA64 and CPU-Z. The Intel Core i3-7350K temperatures topped out at stock settings at 52C and here with our overclock we were hitting 69C. That 900 MHz overclock and voltage increase caused the CPU load temperature to go up 17C with out water cooler, so if you have air cooling you’ll need to keep an eye out on the temps. This was a 33% increase in temperatures due to the overclock.

Our load power consumption went from 78.6W to 94.6W, so our power consumption went up 16 Watts or 20%.

Single or lightly threaded benchmarks on the Intel Core i3-7350K running at 5.1 GHz are simply amazing and it is very comparable to the stock or overclocked Intel Core i7-7700K processor in these types of situations. The Intel Core i3-7350K actually beats the 7700K in Kraken, but there is a +/- 0.5% of wiggle room in this benchmark, so it’s a virtual tie.

It’s only in the heavy multi-threaded applications where the Intel Core i3-7350K can’t compete as it just doesn’t have enough cores.

The overclocking performance of the Intel Core i3-7350K is solid!

Let’s wrap this review up!

    Any reason you only compared the chip with i7s? Why not do the same benchmarks with CPUs in a similar price range? (ie i5-6400)

    • Nathan Kirsch

      Because Intel never sent us any Core i5’s for testing, we didn’t buy any and the money isn’t there to go back and buy them.

  • ireadtabloids

    Found another typo. You call the 1080 a 6GB card on page one.
    Just trying to be helpful. No doubt hours alone doing the hard work testing this thing and writing the article is going to lead to a few typos without some help.

    (add a zero to “Core i7-770K”, p11, final thoughts etc)

    • Nathan Kirsch

      fixed! TY

        Lack of sleep after CES 2017 coverage. 😉

    I’ve a concern with your review regarding the i3 and hypertheading. You have the belief that this is the first in the range to have it, but the i3 has always had this feature and it was and still is the i5 that does not. I had a sandybridge i3 2100 with hypertheading enabled on it.

    • iconoclast421

      That is very odd indeed. Even the very first desktop i3 had hyperthreading. It is sad when the very first sentence has such a glaring error. Fake news?

      Dumbest thing I’ve read all week. I can’t take this article seriously now. I sincerely hope it gets fixed.

  • pretty sweet, i say, lightly threaded, should mean something, ” to me ” it means one thread, internet, second thread, my data base for financials, that is all i need, and what i am going to use, with the small form factor, easy on budget power supply, and taking advantage of the z270 platform, thanks legit, enjoyed your review. , i test my load now on task manager, and look at how my cores are handling data, and still programs are not very good at this thready thing. 🙂 cheers.

    • i have made my second read of this article, ” enjoyed much ” my take away is, the die, is half of the full die, the lowest cost 2 core, at 51 watts, looks to be the real champ, for price / performance, tossing in the other platforms helps, a keeper performance test ” imo ” i am going to build and use two of these processors 7300 for a sff case, with the m2 stick, and change out all my stuff, good bye x58, hello mini 7700 . good article, shows the power of 2 cores,
