revisiting the KB Lakes EQ is to take a look at the more likely purchase for the majority of gamers the Intel i5 7200 K quad core variant we previously reviewed the i7 77 100k and found the CPU to be largely uninspiring with regard to out of box performance gains in gaming though did remark that its render gains that were more meaningful now we're looking at the 7600 K to see how the processor moves Intel i5 series forward before getting to that this content is brought to you by our patreon backers you can go to patreon.com/crashcourse with to help out directly we just reached one of our goals and are producing some more interview content pieces to check that out to help further running through the specs first the Intel i5 7600 expect for an i5 CPU it's four cores four threads no hyper threading and is using 14 nanometer process but it is Intel 14 nanometer + process which increases the thin height and widens the gate pitch and as we discuss in the 77 100k review that improvement is really just what gets them a couple hundred megahertz extra out of the clock so really the main gains for Kaiba lake over skylake just covered again is going to be in the frequency department other than some really specific things like 4k Netflix playback like other case cue CPUs the 7600 K is fully overclockable and pairs best with the z series motherboards we've already detailed the new 200 series chipsets in our 7700 k review again click the link with description below for more information on the chipsets as for the 7600 k specs we have a base clock of 3.8 gigahertz and a turbo clock of 4.2 the cache is reduced to megabytes and total cash from the i7 dropping the 6 megabytes from 8 and otherwise it's largely the same specs and compatibilities the biggest change as always is the have thread count and reduced frequency from the ice own family for details on the kb lake architecture check the links in description below because that's got all of the benchmarks in terms of the actual systems we use the benches defined in the methodology section it changes obviously from one CP to the next because you've got to account for different memory compatibility ddr4 over 3 and then architecture itself is defined on the 7700 K review won't be going over that again today but we can go through the thermals blender benchmark some synthetics and then game benchmarks temperatures with our i-5 7600 K were a bit better than what we saw was a 7700 K depending on a voltage Auto V core things like that I was all discussed in the motherboard reviews by the way but for now what we're seeing is a 74 C package temperature went onto the same way the 77 Rek was under with a VX workload core 0 through 3 were in the range of 67 to 74 Celsius and then the power draw was rated at 97 to about 101 watch or thereabout the core we keep at one point two eight eight it was manually tuned for these numbers and then ambient was somewhere around 25 which is important to note as well and just for what it's worth the liquid temperature was 33 Celsius for the crack and X 62 that we use which was a bit warmer than we saw with the 7700 K and that's just because the ambient was a bit increased during these tests since the value of our normal Delta numbers using our in-house designed blender benchmark guys built by Jen's Andrew Coleman we're recording a total render time on the CPU of approximately 68 minutes with the stock configuration or 62.5 with the 4.7 gigahertz overclocked version as this benchmark demonstrates having the additional threads helps and render workloads as a tool can render two times as many tiles simultaneously the 7600 K takes just under 30 minutes longer to render the scene than the stock 7700 K and is expectedly slower than all i7 cps on the bench other than the ADEs 2600 k compared to last generations i5 6600 k the 7600 KC's an improvement of approximately 5 to 6 minutes or about 7% moving on to synthetics prior to game benchmarks Cinebench testing places the i5 7600 k between the i5 6600 k and the i7 4790k and that's what 716 cv marks for cv performance and 184 marks for single credit performance comparatively our overclocked boosts that up to 788 for total TV performance still below the 4790k and 204 for single credit performance or just below the 7700 K 5.1 gigahertz the i5 6600 K from last generation operated at 664 CD mark sorre 172 single-threaded for 3d mark fire strike and time spies tests again the link the description below has those if you want more synthetics but now we can move on to game FPS benchmarks for these we have a mix of CPU bound games and mixed workload games watchdogs to is one to really pay attention to here because the threads really matter in that game as we just explained in one of our optimizations guides and then total war of course is interesting as well because it is a CPU bound title we recently posted a watchdogs to CPU optimization guide for graphics settings as the game has proven to be one of the few titles that takes advantage of additional threads from higher-end CPUs the line dividing i7 + i5 CPUs here is clear with i7 CPS dating back to Devil's Canyon overtaking and outranking even the i-5 7600 K even with its overclocked 4.7 gigahertz configuration we're still seeing it beaten by i7 for the most part we're also seeing an average FPS of about 93 for the OC 7600 K with the lowest tightly times as shown with other CPUs the non overclocked version rests at 84 FPS average and the Intel i7 7700 K stock operates at 113 average so we've got a gap of about 20 FPS because the two stock KB Lake CPUs looking at the previous generation the i5 6600 K operates at around 39 FPS average so we're gaining approximately 5 to 6 FPS generationally that's a gain of about 7% which in this game anyway is sadly pretty good for this generation of Intel CPUs for Battlefield 1 we're seeing the Intel 7600 KS stock lands at around 140 1sps average roughly equal to the 6700 k i7 from last generation to be fair it's also roughly equal to the 7700 K from this generation which also capture on 141 FPS average compared to the i5 6600 K there's not a ton of improvement we're moving from at 137 average to 145 or a gain of about two and a half percent so not that exciting we only start seeing meaningful gaps once down to the 35 70 K but even that's not very relevant almost dying for 144 Hertz gameplay total war has always been a CPU intensive title all of them really and that continues to shown with total war Warhammer as noted previously the frame times have larger range in total war than were used to so the 0.1% values aren't quite as valuable as normally just because it is a bit more variable in its performance overall we're seeing large-scale ability over the generations of i5 CPUs in this benchmark with the 7600 K it stock landed at 165 FPS average and the 6600 KS Stockland in about 10 FPS below that the i5 4690k from Devil's Canyon operates around 143 FPS era so we're at about a 10 10 10 FPS scaling to each one was the 35 70 K at 99 FPS average the scaling here shows that there would be a major benefit of upgrade for this particular title if moving up from Ivy Bridge or Pryor but not so much excitement beyond that the overclocked 7600 K by the way it shows that frequency matters with Total War and plants us at around 177 FPS average ashes a singularity CPU focus benchmark provides a look at dx12 performance of the title that's well optimized for the new API the 7600 KS stock performs just ahead of the 6600 K and just below the 4790k i7 CPU that's about the same as we've seen in terms of placement with the other games it was far and moving to the overclocked variants of the 7600 K we're posting an FPS that is still below the 4790k but it is getting a bit close at the next step up as for overclocking the 7700 K that we worked with both of them actually were a lot more exciting than the 7600 K we were able to hit five to five point one gigahertz on the i7 variants of KB Lake depending on which one we were working with and that would really wasn't that hard we use the liquid cooler forward of course because it was kind of required at that point but even using the same looking cooler for this one same methodology same motherboard even which was the Z 270 game pro carbon we're still only hitting only hitting 4.7 gigahertz on the i-5 7600 K with one point 4 volts I was kinda able to get some stability with 4.8 gigahertz but that was really pushing the voltage that I was comfortable with and beyond that you start running to some pretty serious temperature issues and there was just stability issues all around so 4.7 was the number we got with our particular sample of the 7300 kay and ours was a retail sample I bought it so if that's worth noting I guess it's out there it was not provided so it definitely wasn't hand-picked or anything like that the 7600 K overall has about the same conclusion as the 7700 K which is if you own sky lake or Devil's Canyon or has well there's really no reason to upgrade for the most part especially for gaming redoing things like animations like the blender rendering there might be a reason to upgrade but gaming not really it's kind of a hard sell even with the CPU intensive titles like the total war watchdogs 5 to i7 would get you a lot more than I 5 to new i5 other than that if you're on something as old as the Ivy Bridge or older than that it's probably worth considering an upgrade but again at this point I would say just wait around a bit we'll see how Zen performs normally we don't recommend waiting but because then is so close and it's been on the radar for years at this point might as well and see how it goes at that point it's worth looking at what the decision would be for an update but for now no real reason if you're on skylake as well double canyon maybe ivy pitch as we've come to expect with the intel generational step so
