    Intel Coffee Lake Core i5-8600K vs 7600K at 5GHz Review

    If you were waiting for huge IPC gains out of the new Coffee Lake CPU from Intel, you might be waiting for a very long time. We take the Intel Coffee Lake Core i5-8600K CPU and match it up GHz to GHz with the Intel Core i5-7600K Kaby Lake processor. And we throw in a Ryzen 7 at 4GHz just for fun.

    My feeling after reading this article.... no really big compelling reason to upgrade from my Devil's Canyon i7-4790k configuration. Sure, there is a performance improvement, but it's yet another small improvement.

    Thank you for taking the time to review this CPU.

    You and me in the same boat, I am inclined to believe that one should never believe in FUD regardless of your colour of choice.

    Did some rewrites on the conclusion page to be a bit more clear and sound less wishy washy. :)

    Which Ryzen 7 SKU was it and what cooling did you run on the 7600K and R7 respectively?

    Nice review. I like clock for clock comparisons best - especially when locked.

    Did you you see a noticable impact for tighter RAM timings? (in case you had the time to test it ofc)

    The 8700K would probably be more interesting with 12 threads.

    Great job getting some numbers up so fast. The conclusion is clear and the data is good.

    Conclusion paragraph: "If you are an overclocking, the CPUs are the same for all intents and purposes, so the $5 price difference makes sense." Maybe get rid of "an" for "If you are overclocking, ...". Also, ensuring people know what the $5 price difference is would help. If people skip to the last page, and read the conclusion without following the price link, they won't understand. Maybe, "If you are overclocking, the Ryzen CPUs are the same for all intents and purposes. So, the $5 difference between 1700 and 1700x makes sense."

    Spelling error on heading for graph of "Handbrake - DVD to Andriod Preset" with Android. Swap 'i' and 'o'.

    Wow... Ryzen has some sweet ass Handbrake numbers.

    Pretty much what I expected out of Coffee Lake's IPC. I'm banking on the two extra cores and the 15% increased clock speed (going from 4.5Ghz to ~5Ghz) making the upgrade worth it for me (coming from a 4770k and going to an 8700k).

    Thanks for the review Kyle, Coffee Lake sounds impressively mediocre.

    The one thing I didn't like about all the intel chips from i5-3570k was the lottery aspect of how well it would overclock.
    Well, okay, there are more than just that, like TIM and lack of improvement, but it is nice to finally have an improvement over the previous gen.

    Now the hard part is... R7 or six core i5...
    Ryzen matx mobos are just... ugh...

    I'm building a rig for the GF for Destiny 2 so I was pretty excited to see how these stacked up. I was hoping for great performance so I could update my rig and give her my Ryzen 7 rig on the sly. From this though I might go base I3 with a cheapo board and just wait on Zen+/2 for my own rig later. Lets see how benchmarks shake out on the other lower end cpus.

    It's time for me to upgrade my 3770k, I was holding on for Coffee Lake in the hopes there'd be an actual performance increase for normal users, but once again it's just: "MASSIVE 15% performance increase! ... for the tiny slice of the PC market that just encodes video all day and/or run 70 applications at once and want to shave 50c off their electricity bill while doing that..."

    Ultimately I guess CPU performance simply isn't a bottleneck for general PC use (i.e, anything that doesn't rely heavily on on having more than 2-4 cores), and hasn't been for years, and likely never will be again, which isn't exactly a terrible problem to have, but it feels a bit scam-like that I need to buy a whole new system at this point to get stuff like nvme and M.2 support without getting any meaningful CPU gains

    Going from a R7 to 8700K would have been more expenses on top of what already cost a fair amount to build.

    Have you considered a R3 1300X or Pentium G4560 build for the girl? I built my step brother a gaming rig to play NewZ, DayZ, Unturned with me, used a Ryzen 3 1200 on the BIostar ITX board and tossed in a M.2 and GTX 1060 6GB and that thing games well.

    There are those that refuse to see anything bad and will bash you for your reason irrespective of whether you use Intel or not, I am seriously considering building a ryzen setup but will rather wait for Pinnacle Ridge before deciding, right now my 4790K is still looking very good.

    We weren't expecting any IPC increase, were we?

    Sky/Kaby/Coffee should all look the same normalized for clockspeed, from what I've seen. Kaby was more of a clockspeed/overclocking thing on desktop, but a nice boost for sustained clocks on mobile, and Coffee just added cores and more power on the desktop, right?

    I think IPC gains are forgone conclusions, but 15% tout looks like bum fluff

    I guess since we are talking about Intel next-gen chips, we should assume no IPC increases ever again.

    Not
    Not by this guy, have blue is every system, wanted to replace my Xeons with Threadripper but held onto team blue since they passthrough better than Ryzen/Threadripper... However I might be building an 1700x/1800x as an upgrade to my main PC.

    Thanks Kyle. Im NOT impressed as you seem to also not be. I am waiting on a proper 8700k review. I want to see what the extra cache and hyper threading offer in the productivity environ before buying one as a second machine.

    After this I am truly happy with my 1950x.

    Since IPC is not gaining momentum, AMD has a little catching up, it would appear we have truly entered a long term core war. MOAR CORES please sir.

    But Coffee isn't 'next gen', is it?

    I thought it along with Kaby were more of a 'filler' as Intel was having trouble with nodes, so we got four on 14nm instead of two, with Skylake being the only architecture change (the 'tock'), and following two being minor tweaks and core increases.

    Does it come with an intel free delidding extended warranty card? or at least a few surgical razors?

    Intels own slides call it next gen, irrespective of whether it is just another process on the same node it is still next gen.

    This is why I don't believe Intel marketing anymore than I believe AMD's, I think Intel have a history of befuddling and they did that with Kaby claiming 10% gains on a 7700K vs a 6700 which was put in the smallest fine print at the bottom.

    Sysmark really? I remember when Intel used Cinebench to rub it in AMD's face and yes AMD did everything wrong with Bulldozer, but notice how fast Intel dropped Cinebench as their alpha benchmark, even though we know that they have a clockspeed and single thread advantage. Ryzen isn't perfect but I think AMD has done better than most would have thought or wanted to believe possible.

    I was thinking i3 8100 so still a quad as long as some cheap 300 series boards pop up. Otherwise yeah looking at 1300x or 1400 just for the HT and have a old 780 that can still run things well enough. I would love a 1600 but since trying to keep costs down and she wouldn't really need it and hard to swing it on the budget. Hoping for a sale or something on things in the coming weeks.

    Yeah, I'll ignore the 'marketing' slides. Those aren't for us.

    I want to know what it is.

    Wow, not sure if I'm happy or upset with Intel.

    I was sure Intel was sandbagging because of lack of AMD competition.

    Now it looks like they were not. I was expecting a 15% IPC increase to be real. Silly me.

    I think I will still get an 8700k since it is still going to be the fastest single threaded CPU around.

    Its been known for quite a long time the first changes for the desktop comes with Icelake in terms of core IPC and CFL would use the exact same cores as SKL and KBL.

    If you match SKL/KBL/CFL with the same core count, same clock and same memory you are pretty much going to get the exact same performance. But that's not the difference, unless you want it to be.

    CFL gives you 50% more cores within the same TDP and higher stock clocks. And by the looks of it, higher OC clocks too.

    Any "IPC" changes would have to come from the L3 size increase for CFL.

    Intel already got the fastest CPU, now you get 2 cores more without any sacrifice for the same price. I can see the let down there. :eek:

    Kyle, the Coffee Lake CPUs use the same core as Skylake and Kaby Lake, so an IPC increase was not to be expected. The main improvement with Coffee Lake is the addition of two more cores as well as an enhanced manufacturing technology that pushes clock speed higher.

    Single core performance is the product of frequency and IPC. IPC hasn't gone up, but since Skylake, Intel has been pushing frequency capability up, so single-threaded performance goes up.

    480P results have the mystery Ryzen 7 delivering performance close or better than the Kaby and CFL with about 40% lower clocks, and granted they are now under 300USD it just seems like a let down. If you factor in that the 8600K will have no cooler the added costs make this more of a 320+ dollar experience.
