If I’m being sincere the Kaby Lake launch firstly of the 12 months was a little bit of a moist squid. I’m conscious that’s not the standard phrasing, however the Intel Core i7 7700K bears extra relation to a soggy cephalopod than it does a firecracker. As ever although, for us players, it’s the cheaper Core i5 which is arguably extra attention-grabbing and the i5 7600Okay proper now could be wanting just like the go-to Kaby Lake chip for gaming.
A very good stable state drive could make an enormous distinction to your machine’s efficiency, so try our information to the best SSDs for gaming.
I not often give a pair of fetid dingo’s kidneys a couple of new Core i7 except it’s acquired extra cores in it than a boozy West Country cider. And so it got here to go with the Kaby Lake Core i7 – it was a frickin’ yawn-fest.
A CPU era’s Okay-series i5 nevertheless remains to be capable of ship nearly similar ranges of gaming efficiency however for a considerably lowered worth. And the identical is true right here, with the 7600Okay at $229 (£215) being over $100 cheaper than the 7700Okay.

Intel Core i5 7600Okay specs
As it’s a Core i5 processor the massive distinction between it and the i7 is its lack of HyperThreading. Intel’s HyperThreading permits a single CPU core to course of two threads concurrently, giving it higher multithreaded grunt than it could usually possess. That means, whereas the Core i7 7700Okay is ready to successfully function with eight digital cores, the Core i5 7600Okay has to make do with solely 4 precise cores.
If you’re doing numerous CPU-intensive media work, reminiscent of picture manipulation or video/3D rendering, these further processing threads make an enormous quantity of distinction, however while you’re speaking about gaming, not a lot. We could also be dwelling in a world the place video games consoles have many, many (admittedly garbage) CPU cores however nonetheless our video games profit most from having actually good single-threaded throughput. That’s why AMD’s earlier processor structure foundered so badly – Bulldozer hedged its bets on a multithreaded future which nonetheless hasn’t fairly occurred – and why Intel nonetheless guidelines the roost when it comes to the best CPUs for gaming.
Like the i7 Kaby Lake chip, the i5 7600Okay has additionally had a comparatively wholesome pace bump over its predecessor. The Skylake model runs at three.5GHz out of the field, with a three.9GHz Turbo, whereas this Kaby Lake chip begins at three.8GHz and Turbos as much as four.2GHz. Straight away that offers the brand new chip a bonus. Though the identical could possibly be mentioned for the rival Kaby and Skylake i7 chips, and look how that turned out…
Elsewhere it’s a lot the identical story as with the earlier era’s i5. It’s nonetheless rocking a 91W TDP, 6MB of cache and the identical socket and reminiscence compatibility configuration. As it’s a Kaby Lake chip although it does include the brand new media engine inside it, which suggests now you can stream 4K content material from Netflix to your PC. If you get the upgraded Netflix sub, have a 4K monitor and keep in mind to make use of the Edge browser.
The Edge browser. The one Windows retains telling you to make use of. No, it’s not Internet Explorer. Well, it sort of is. Anyway, it’s the one one which’s allowed to speak to Netflix’s 4K catalogue, so simply use it for that and don’t blame us.
The i5 7600Okay additionally has some CPU graphics silicon inside it too, however we’ve all acquired graphics playing cards in our PCs, proper? So we are able to just about ignore that proper now…
Inevitably the straight CPU efficiency of the Core i5 7600Okay is off the tempo in contrast with the far more costly, eight-threaded i7 7700Okay, however due to its comparatively excessive out-of-the-box clockspeed it’s mighty shut when it comes to single-threaded grunt. That greater clockspeed additionally means it’s acquired the leap on its i5 6600Okay predecessor.
Those single-threaded efficiency numbers listed here are key while you shift focus to the gaming efficiency of the 7600Okay. Because the i5 performs so intently to the i7 when it’s prioritising a single thread the gaming body charge distinction is, to all intents and functions, invisible. Even within the CPU-aware DX12 and Vulkan APIs it’s troublesome to discern any variation in gaming efficiency.
The artificial Time Spy DirectX 12 benchmark does although spotlight the disparity on the CPU facet, with the i5 7600Okay exhibiting a a lot decrease CPU rating than the i7 7700Okay. Maybe when video games are constructed from the bottom up for DX12 the variations will change into extra stark in body charge phrases, however till then why would you, as a gamer, want an i7?
There are, nevertheless, apparent variations in relation to the relative storage efficiency of the 2 CPUs. When plumbed into the system’s PCIe bus the sequential speeds are nearly similar, however while you have a look at the random write efficiency there’s a drop-off with the i5. The Core i5 7600Okay can be a contact slower when it comes to compressing and unpacking a blended media folder.
Where issues get extra thrilling is within the overclocking stakes. This is extra prefer it. This is what we have been hoping for from the 14nm+ lithography of Kaby Lake. Without the HyperThreading of the i7 7700Okay our Core i5 7600Okay blasted previous the 5GHz mark with ease. Our pattern ran all the best way as much as a rock-solid 5.1GHz, solely tapping out once we pushed it up in direction of 5.2GHz – and even then it was nonetheless booting. Looking on the 5.1GHz Time Spy benchmark you may see the variations between the 2 Kaby Lake Okay-series chips actually shrink down.
That is although all on the expense of the thermals. Realistically you’re not going to need your costly silicon to be working at 99°C for lengthy… That’s the place options just like the Overclocking Temperature Control within the Asus TUF Z270 Mark 1 motherboard actually comes into its personal.
The Kaby Lake era isn’t going to set the world alight the best way a few of Intel’s earlier chips have carried out. Rather than Process>Architecture>Optimisation it’s seeming a bit extra like Process>Architecture>Flog horse. The tertiary optimisation section of Intel’s CPU launch cadence is extra about consolidation than the rest; definitely not innovation.
But the Core i5 7600Okay nonetheless has extra about it than the fantastically uninspiring i7 7700Okay. The worth is true, the gaming efficiency is there and it’s capable of overclock like a champ. Sure, in the event you’re sitting on an i5 from any of the final couple of generations you’re not going to realize a lot from making the improve swap, however in the event you’re ranging from scratch then the i5 7600Okay is good spot to construct from. You can wager there are going to be some spectacular pre-overclocked full rigs launched with the 7600Okay at their hearts.
The caveat right here although is that in the event you are ranging from scratch then there’s a superb case to be made for choosing one of many newest AMD Ryzen CPUs. The unbelievable AMD Ryzen 5 1600X particularly is the largest challeng to Intel’s Core i5 vary and one of many driving forces behind the next-gen Coffee Lake vary providing a six-core i5 processor for the first time.
The 1600X comes with thrice the thread-count of the 7600Okay and all for a similar worth. In phrases of gaming efficiency the speedy single-threaded chops of the Intel chip provides it the win, however solely ever by a small margin. With the worth being so shut you are sacrificing a really small quantity of legacy gaming efficiency for an enormous uptick in multi-threaded prowess.
For pure gaming efficiency the Intel chip nonetheless has the win, so if all you are ever going to do is single-thread-heavy gaming then the overclocked i5 is a superb choice to type the beating coronary heart of your subsequent PC construct. But so many people use our PC for an awesome many different issues, and with the way forward for PC gaming assuredly being multi-threaded, it’d show to be a short-sighted alternative.
