Civilization VI, Battlefield 1 & Dawn of War III

Civilization VI AI Test

Our Civilization VI AI test measures performance in a turn-based strategy game, and it tends to favor a mixture of high frequency and core count.

Core i3-7350K performs well in this test, though the i3-8350K leads once we start overclocking. Notably, Core i5-8600K offers nearly the same performance as an overclocked i3, but accomplishes this at its stock frequency. The Ryzen 3 1300X also performs well, beating out more expensive CPUs.

The Kaby Lake-based -7400 languishes at the bottom of the group due to its 3.5 GHz peak Turbo Boost frequency.

Core i3-8350K is impressive during the Civilization VI graphics benchmark at stock clocks rates, where it essentially ties the Core i5-8600K and surpasses the Core i5-8400. Tuning provides a nice boost that catapults Core i3 ahead of everything else in our test pool. It seems this title responds exceptionally well to four physical cores, even if the -8350K encounters higher frame time variance in the beginning seconds of our benchmark.

Core i3-7350K's bottom-dwelling performance serves to hammer home the -8350K's step up: it provides a 20% advantage over its predecessor at stock settings. Tuning the Kaby Lake-based chip doesn't do much to close the gap, either.

Ryzen 5 1500X can't match the Ryzen 5 1600 when we lock them to the same frequency, showing that Battlefield responds well to higher core counts, among other factors. 

Warhammer 40,000: Dawn of War III

The Warhammer 40,000: DoW III benchmark scales well with execution resources, but aggressive clock rates also provide a big benefit.

Intel's Core i3-8350K falls beneath the i5-8600K and i5-8400 at stock settings, and the tuned Ryzen 5 1600 also proves to be a formidable competitor.

Overclocking the Core i3-8350K unleashes a big speed-up, though, that reminds us of what we saw from Intel's Core i5-8600K. We don't have the overclocked -8600K in this batch of results, but it does outperform the -8350K with 122.8 FPS.

    Newegg shows the Core i3-8350K in-stock right now for $189 (still $10 higher than "recommended customer price" from Intel), but well below the pricing button that says it costs $250 on Newegg. I thought those pricing buttons were updated real-time now?

    Intel made a mess of a rushed launch to answer Ryzen, but there is one thing they are unbeatable: low price. I know, they have always been expensive, but given the circunstances, it's very easy for them to underprice their chips to have better value.

    Well, sounds bad, but then again AMD triggered this, and consumers are the winners, right?

    Dude, i'm in limited quota here..

    I dont want to waste every bit for some useless video..

    So my I7-4790K is now being beat in cinebench by an OC i3. At stock speeds it gets a Cinebench score of 830 and the OC i3 gets 840. So glad i can still OC it and at least beat the i3.

    Should i assume it to be as fast as a STOCK i7 4790k? At least when only 4 cores are required?

    I believe we need to stop putting so much emphasis on <current> single threaded performance. As long as the difference is not over 20%, for gamers and power users this matters less now.

    All games, all apps and even browsers are going Multi-Threaded so what's the point in putting so much emphasis on Single Threaded performance ?!?

    Sure, if AMD or Intel launch a new gen of CPUs that double or triple the single threaded performance, that's worth the talk, but differences between 0% and 15% are not worth to fill entire pages of a review with.

    Anyway, I'm not an expert reviewer :) It's just my opinion after 20+ years in IT hardware industry.

    I generally want a very capable processor at a good platform price with modest IDLE power consumption. The rest is arguable. If it can game, good. If it can game well, even better, but I'm never going to chose a less productive CPU just because I get 10% higher FPS. That's just me :)

    The graphics can be a bit misleading .... I would really like to see them full scale.

    Because the way they are now, you get the impression that (in Gaming Price Efficiency - Platform Cost) AMD Ryzen 1300 is 10 times less capable than the i8400 which is not.

    When you look at the dot placement on the table, you'll see that i5 8400 appears to be 1000% the performance of AMD Ryzen 1300 while only being 2 times the price.

    I've been waiting for this review. I'm looking to replace my dying i5 2500K backup gaming rig using a 1080p monitor that was built in Jan. 2011. It's severely showing its age. The price of the 8350k is a little higher than I expected, but since that rig is only for gaming and nothing else, the overclocking capability of it is impressive for improved FPS performance. And as the game benchmarks show, we are still not seeing most AAA title games really taking advantage of more than four cores over an overclocked four core CPU.

    If I was wanting to build a combination of both a gamer and multi-threaded video rendering box I'd still probably go with the Ryzen 1600 or 8400, but for a strict gaming box and going for a killer overclock, this wins hands down in the price segment. RIP to my faithful and trusty Sandy Bridge. You served me well for seven years - a chip that I successfully overclocked to 5.0GHz as well but never kept it that high due to the at-the-time rather weak Zalman 9700LED cooler...weak by today's higher end cooler standards. And thank you AMD for putting the pressure on Intel to add more cores to their i3 and i5 chips.

    shows $189 for me. I doubt the button is updating it's pricing in real real-time. Probably more like once an hour.

    I know, this has bothered me in every review on this site that I have seen. I understand that its important that you inform consumers that you will need to purchase a heatsink, but if you are buying a -k chip and a z- motherboard, it seems likely that you'll want an aftermarket cooler. I would MUCH rather intel prices these chips $10 lower and not include a paperweight.
