Are Unlocked "K" CPUs Worth it for Gaming?

Josh hey what's up man so look I know that you said that the core 500 toaster can fit full-sized video cards and AIO liquid coolers but dude I can't even fit the motherboard in the damn thing so what's the deal so if that's not the core 500 hippy huddle Barney wouldn't keep don't buy him yet it opened up the core 500 from fractal design provides top-class cooling and supports full-sized hardware in a compact design click the link in the description to learn more bread toasting only supported with AMD chips what's up guys so if you're looking to build a new gaming PC and your heart's already set on an Intel Core processor the next thing you might want to consider is whether to spend the extra cash on an unlocked case q for those of you newbies out there okay at the end of an Intel Core CPU part number indicates that the multiplier of that processor has been unlocked meaning it can be overclocked by the end user to achieve clock speeds faster than what's advertised on the Box all in the name of increased performance this potential for extra performance comes at a premium with unlocked CPUs typically costing anywhere from five to ten percent more than their locked core counterparts plenty of synthetic benchmarks show big gains from overclocking Intel processors but when it comes purely to gaming what real-world performance gains can we hope to see from CPU overclocking and does that benefit warrant the premium price of a case few chip what makes this a worthwhile discussion is that most games these days most games these days are heavily GPU dependent so putting the money saved on CPU overclocking costs towards a faster video card for example might be a wise choice when it comes to sheer gaming performance to investigate the matter I ran a few benchmarks with the core i5 6600 K at both stock frequency to emulate a locked 6600 and overclocked to 4.6 gigahertz pushing the limitations of the unlocked chip also in our test bed is the z170a gaming pro motherboard from ms I 16 gigs of g.skill ddr4 and a ZOTAC gtx 980ti amp Edition running at stock clock frequencies all tests were run at 1080 1440 and 4k on Windows 8.1 so starting with Metro last light at very high settings we see our average FPS at 1080 jump from 103 to 111 when overclocking which is a respectable 8 percent performance increase from simply tweaking our CPU however this boost begins to taper off at higher resolutions which is a likely indication of GPU bottlenecking now that our gtx 980ti has its hands full rendering those extra pixels our CPU overclock is sending instructions faster than the card can execute hence the smaller impact on performance if we were to throw in another 980ti for two-way SLI I'd imagined we'd once again be CPU bound and see more mileage with our overclock at these higher resolutions oddly enough minimum frame rates decreased from our boost but as you're about to see that trend lives and dies with this title in GTA 5 once again we see more dividends from overclocking at 1080 and less payout as we go up the resolution scale still we see a sizable 11% average FPS increase at 1080 and a more modest gain at quad HD even more exciting perhaps is the impact our overclock has on minimum frame rates here at 1080 we see a 52% increase quad HD goes from the 30s to the 50s and even 4k receives a nice bump these higher minimum frame rates can help produce extreme FPS drops when using double buffered vsync for example while providing an overall smoother gameplay experience so this is a big victory point for CPU overclock II similar results were achieved in hitman absolution except we see little difference in frame rates between 1080 and 1440 revealing a bottleneck with our 6600 K if the CPU could keep up with our video card there's a fair chance we'd see higher frame rates at 1080 even at 1440 the 980ti is drawing frames with time to spare and this is exactly why overclocking the CPU has a big impact on performance here the one exception is 4k where our video card finally gets to slammed to benefit much from our CPUs boost so what's to be gathered from all these results well the hard data suggests that CPU overclocking is generally more effective at increasing the average and minimum frame rates when gaming at lower resolutions like 1080 where the GPU still has some breathing room to process incoming commands at a faster rate overall we saw an eleven point seven percent increase in average FPS when gaming at 1080 which definitely builds a strong case for unlock chips depending on the game CPU overclocking can make an impact at quad-hd - albeit by a smaller amount as we saw 6.7% increase across the board and average frame rates in most cases if you're gaming it either of these resolutions it's hard for me not to recommend paying the extra ten or twenty bucks on a case cube processor with just a 2.2 percent average FPS boost at 4k don't expect pushing your CPU to score you any mad gains unless you're playing a heavily CPU intensive game or have a powerful multi-gpu set up looking at it from strictly a price to performance perspective you'd essentially be spending five to ten percent more on an unlocked CPU for just 2% more performance in game and while that doesn't sound very appealing at face value there's more to overclocking than peer gaming performance even if you're not taxing your CPU with things like encoding and rendering simply having the opportunity to overclock is the best way to learn more about it and the impact it has on your system apart from being a hands-on learning tool overclocking can also be a fun hobby or pastime that really becomes more about the hardware's capabilities than the user experience one person on the Tom's Hardware forums phrased it best by saying some people own a car to get from point A to point B and some people own a car to drive it but that's pretty much gonna wrap it up for now guys so let me know your thoughts on CPU overclocking in the comments and don't forget to toss me a like on this video if you enjoyed it before you go check the description below for refreshed CPU cooler shirts like this one in a brand new material oh it's so soft and also feel free to bookmark my Amazon affiliate link and use it when you buy stuff man helps me yeah as always some care about themselves and network thank you guys for watching subscribe to the channel if you haven't already and I'll see y'all in the next video
