The Core i5s lead while a previous-gen Core i3-6320 beats the stock Core i3-7350K, but can't hold off the dual-core chip overclocked.

We see a finishing order that reflects a preference for more physical cores, followed by Hyper-Threaded dual-core CPUs. AMD's Athlon X4 750 at least has two clustered multi-threading modules to throw at the problem. The Pentium G3258 has no such feature, and it stumbles hard.

The stock Core i3-7350K nudges past Intel's Core i5-7500. The Athlon X4 750K falls into a class of its own at the bottom of the chart.

Intel's overclocked Core i3-7350K tears through this sequence ahead of the beefier quad-core competitors. Even a stock -7350K leads the Core i5-7400. 

The heavy test is more taxing, but still favors the Core i3-7350K's higher frequency over more physical cores.

When we activate OpenCL, AMD's Radeon RX 470 reduces the project's completion time significantly. If you have a compatible GPU at your disposal, OpenCL offers a radical performance increase. The Athlon X4 750K struggled mightily during the CPU test, and we conducted the test several times to verify the result.

Up top, the Core i5-7600K and -7500 predictably finish this benchmark first, but an overclocked Core i3-7350K demonstrates that it can triumph over Intel's Core i5-7400, even in a well-threaded application. The Pentium G4620 also receives a nice bump from Hyper-Threading, allowing the dual-core CPU to beat AMD's Athlon X4 750K and the Pentium G3258.

The overclocked Core i3-7350K's high frequency propels it to the top of our chart, while the Core i5-7600K slides into second place by virtue of its top 4.2 GHz Turbo Boost bin. Naturally, if that processor were overclocked as well, it'd be right up there with the -7350K. Intel's Core i5-7500 benefits from a 3.8 GHz Turbo Boost ceiling to zip past the Pentium G4620's fixed 3.7 GHz clock rate.

Other Intel CPUs fall in line according to frequency. Meanwhile, the Athlon, based on AMD's Piledriver architecture, lands in last due to its IPC throughput deficit.

Our overclocked Core i3-7350K leaps ahead of the stock -7350K, which the Core i3-6320 nearly catches. AMD's dual-module Athlon X4 750K benefits from its additional integer cores, beating Intel's Pentium G3258 by a fair margin.

An aggressive clock rate puts Intel's Core i3-7350K in first place with 146.85 FPS. The Core i3-6320 trails the stock -7350K by a hair, while a Pentium G4620 bests the more expensive Core i5-7400.


Intel's Core i3-7350K surfaces as the fastest dual-core CPU, and it nearly catches the Core i5-7400 after our overclocking efforts. Intel's Pentium G3258 struggles under the workload's weight (it took 3.5 hours to finish), while the Pentium G4620 leverages Hyper-Threading to fare much better. Still, this benchmark wants more cores than the Pentiums offer.

Our chart's finishing order is almost exclusively organized by clock rate. The Core i5-7600K's Turbo Boost technology yields a slight advantage over the Core i3-6320. However, an unlocked multiplier makes the i5 ideal for further tuning. Without question, an extra 500 or 600 MHz would yield near-parity with the overclocked Core i3.

While Core i5s dominate the upper range of our chart, overclocking the Core i3-7350K pushes it up into second place.

The Pentium G4620 barely succumbs to Intel's Core i5-7400, which we wouldn't expect given the cheaper part's clock rate advantage.

As we saw in Cinebench, an overclocked Core i3-7350K enjoys a victory lap, but places third in its stock configuration.

    As someone who just enjoys overclocking and was coming from an FX chip, it is nice but I agree with the rest of the article ; a locked i5 is a very solid chip for similar pricing to the unlocked i3 which may fare better or worse.
  • Sakkura
    It simply needs to drop $20. I suspect they may have launched this chip, and the hyperthreaded Pentiums, as a precaution for Ryzen. Intel doesn't usually adjust pricing, but I would not be the least bit surprised if the 7350K becomes an exception after the Ryzen launch (assuming things go well for AMD).
  • ubercake
    These processors are $159 at microcenter. That's the $20 price drop Sakkura is looking for! I think I'd still just fork over the additional $40 (again microcenter) for the i5 though.
  • InvalidError
    Given how expensive the top-end i3 has become and the extra expenses that go in actually leveraging its overclockability, I'd say that the i5-7400 with a h270 motherboard would be the better bang-per-buck option in most cases. At least until Ryzen comes along 2-3 weeks from now and redefines what good bang-per-buck is.
  • ubercake
    I really hope Ryzen lives up to the hype. I can't wait to see the R7 1800X vs. i7-6900K reviews.
  • Ashwaganda
    With 168$ MSRP this cpu just isnt attractive, considering i5-7400 182$ MSRP.
    Even if you could overclock it with cheaper H110/B150/B250 board, the i5-7400 is a better buy. Also the 63$ Pentium G4560 utterly destroys i3-7350K by value.
    Sure G4560 does not have AVX instructions, but who cares. For gaming and everyday use purposes AVX doesnt offer any real benefit.

    The only reason I'd pick up this would be for playing games like Sins of a Solar empire that don't make use of enough cores and loads the screen with lots of processing at end game.
  • logainofhades
    These are selling for $180 right now. Simply not worth it. At least the pentium G3258 was priced close to its locked siblings. The price needs to drop, significantly. At current prices, and with the hyperthreaded Pentiums, the i3 is kinda irrelevant right now. Wonder if Intel knows something about Ryzen, that we don't, because these recent moves don't make a lot of sense.
  • why_wolf
    I really get the feeling this chip is being setup so Intel can drop the price on it if AMD eats to much of the low end market. As it stands right now, at this price point, I'd have to agree going to an i5 instead makes way more sense for the majority of users out there.
  • Math Geek
    the G4620 stands out more in this review to me than this i3 does. at ~$90 it is a much better buy than this i3 for a true budget build. once it's price drops in response to AMD, then it will be worth a revisit once we know what AMD has to offer. but for now, i won't be recommending this cpu to anyone. locked i5 much better bang for the buck with the locked i3 or this new HT Pentium for a budget build.
