The Core i7-6700K and 5775C are both available now

Our gerbil-eyed "chuckula" spotted three animals today, often spoken of in tale but yet to be seen traipsing around in the wild. I'm talking, of course, about the Skylake Core i7-6700K CPU and its cousins, the Broadwell Core i7-5775C and i5-5675C.

If you need a refresher course, those are the goodies you're looking for. Scott tested these CPUs recently and, in short, you want'em. The newer Skylake architecture on the 6700K lends itself particularly well to multithreaded and productivity applications. Meanwhile, the Broadwell 5775C (and to a lesser extent, the 5675C) is nothing short of a freak gaming monster, thanks to its 128MB of L4 cache. Yes, megabytes.

If you were itching for an upgrade and your credit card was already trying to sneak out of your wallet, then now's the time to hold it in the air with all your might. Newegg has the fantastic trio in stock. The Core i7-6700K is available for $370, the Core i7-5775C will set you back $420, and the Core i5-5675C with "only" 4MB L3 cache (but still retaining the prodigious 128MB of L4) comes in at $320.

    As of Monday 9/28 a couple non-K alternatives have just shown up on Newegg:
    i7-6700 – $329.99 – [url<]http://www.newegg.com/Product/Product.aspx?Item=N82E16819117560[/url<] i5-6500 - $219.99 - [url<]http://www.newegg.com/Product/Product.aspx?Item=N82E16819117563[/url<] i5-6600K still out of stock.

    If my current CPU suddenly quits I’d probably make a beeline for the 6700K. It just hurts a little bit how it’s priced at $370. Is this the official price or are retailers just pricing high for now?

      • Freon
      • 6 years ago

      That’s MSRP. Your best bet on a better deal is having a Microcenter local to you and waiting for them to do their loss-leader CPU sale.

        • ronch

        In case you don’t know, the U.S. isn’t the only country on earth.

          • Freon
          • 6 years ago

          You posted the (nearly exact) MSRP in US dollars of the product, this site is based in the US and always quotes US dollars, what do you want me to assume?

          If it makes you feel better, I do not have a Microcenter in my city despite it being the 14th largest city in the US. I paid MSRP off Newegg for mine. We have one Fry’s, that’s it for places that would carry such things in stock for consumers.

            • ronch
            • 6 years ago

            Of course Intel quotes USD prices, and everyone else the world over will likely base their local prices on that. And as the msrp of the 6700k is, AFAIK, a bit higher than past i7s, how would you think it will affect prices the world over? You think they’ll be cheaper or just be the same? Point is, generally speaking, Skylake prices look like they’re creeping up. Microcenter’s deals are a different story. Good too if you live near one, but most of the world doesn’t, so for most of us, MC is pretty much irrelevant.

      • flip-mode
      • 6 years ago

      I’d get either a 4770 (non-K) or the 5775C simply because I’m not giving up my 32 GB of DDR3 (that I very rarely make legitimate use of) any sooner than necessary.

    • the
    • 6 years ago

    Considering that the the i7 5775C is an unlocked chip and is supposed to be a drop in replacement on an existing platform, I’m not too surprised by the premium price. It certainly feels like Intel finally made a chip ‘too good’ for consumers with the eDRAM.

    Normalize for clock speed and the i7 5775C is very, very competitive with Sky Lake.

    Of course I’d personally like to get the best of both worlds: Sky Lake + eDRAM but Intel has forsaken enthusiasts like me. 🙁

    Ive got 2 builds going right now, got my chips in yesterday, will be posting up on the forums sometime over the next month with full overclocking details.

    Build 1: 6700K Z170 Asus Maximus VIII Ranger, custom waterloop, delid+naked EKblock kit (lid staying off). Going to run with a M2 SSD (sammy 950 pro I bet).

    Build 2: 6600K Z170 Asus Pro Gamer, Delid (but cap going back on) and Hyper Evo 212

    Staring the 6700k cutting right now (just bench tested it with the stock cooler from my 4790k to be sure board/ram/cpu were all good, installed windows on a old SSD until I can get the M.2 one I want):

            That’s fine. Those dimensions still come out to about 123 mm^2, and that’s +/- 1% from my estimate of about 122.5mm^2 so we know the die area with pretty high precision now.

    • floodo1
    • 6 years ago

    $420 for the 5775C is insult to injury. Intel promised the chip in Q2 and only soft launched it then, and now are charging $90 premium over the 4790k price? RIDICULOUS!

    I’ve been waiting since May for this CPU but I might just buy a used 4790k and save well over $150 dollars.

    These prices are super super lame.

      • yuhong

      Intel’s own MSRP isn’t even that high.

      • watzupken
      • 6 years ago

      Firstly, I think this is overpriced by the retailers since its pretty rare at the moment.

      Secondly, if this is priced about the same as the 6700K, I believe the 5775C will outsell it easily. At 65W and with its 128mb E-DRAM, it is easily the better choice for me. Personally, I believe the older Broadwell may perform just as fast if not faster than Skylake. Which is why all the reviews so far only pit Skylake against Haswell instead of Broadwell.

        • Ninjitsu
        • 6 years ago

        It’s $40 over the 6700K (Intel prices).

      Current prices here in DK are still expensive

      $456 (3050Dkk) for the 577C and
      $472 (3150Dkk) for the 6700K.

    • NeelyCam
    • 6 years ago

    Now I’m really curious about how well 5675C does compared to 5775C, 6600K and 6700K.

    EDIT: I would throw in 4790K, 4790 and 4690K as well. Could be interesting.

      • Freon
      • 6 years ago

      5675C and 6600K benchmarks are actually kinda hard to find, especially comparing to their top-end brothers in gaming.

      From what I could find, it seems the 6600k cannot keep up with a 4790k. Both seem plenty sufficient for gaming where GPU is usually bounding, but hyperthreading seems to kill it in a lot of other benchmarks like Cinebench.

    • Freon
    • 6 years ago

    Just pulled the trigger on a 6700k, Gigabyte UD5, and a G.skill 2800 1.2v 8×2 RAM kit off Newegg. Finally time to retire the poor weathered i7-950 setup.

    I started looking at the UD5 based on TR’s Gigabyte Gaming 7 review. I just wanted almost the same thing less the Killer NIC and Creative audio, seems the UD5 was right on target.

    • GrimDanfango
    • 6 years ago

    How many generations away do you reckon we are from Crystallwell finding its way into the “E” 6 and 8 core chips?

    My work involves a fair bit of fluid dynamics, so it would likely be the absolute ultimate killer chip, if it ever came to pass.

    I’m confused as to why such a potentially beneficial technology is being limited to mobile and mobile-packaged-for-desktop applications. It seems as though Intel have only considered the use of eDRAM for the onboard graphics, while it rather obviously has some powerful alternate applications.

      • UberGerbil
      • 6 years ago

    I saw some 6700K CPUs at Microcenter on Tuesday. Thought, “Neat.” and walked away. Finished my 5930K build a month ago…so not in the market anymore. However, a friend is needing to upgrade from his Core 2 Quad Q6600!

    • Bensam123
    • 6 years ago

    Mm… if the ‘C’s come down in price I may consider upgrading from my 4690k to the 5675C. Right now the 4C/8T i7 compared to the 4C/4T with eDram seems like a toss up. I guess that’s why they’re priced so.

    • kuttan
    • 6 years ago

    That’s too pricey. It would be better to buy a Hexa core i7 5820K for $390 than $420 Quad core Core i7-5775C. eDRAM is a honey trap.

      • guardianl
      • 6 years ago

      Yeah, there’s no disputing that the i7 5775C wins a lot gaming benchmarks, but we’re talking generally less than 10% at the extreme compared to the 4790k. In other games, it’s more than 10% slower than a 4790k – it’s very title / settings dependent. I think Scott’s particular game collection just happened to hit some of the more compelling outliner ones by chance too, since other review sites see more misses.

      • 6 years ago

      What are you talking about?! The innovations for the core platform over the last 5 years has been HUGE. The innovations however have been in mobile, since it’s probably where intel is able to generate most of it’s profit for performance class CPUs. It’s the reality of being in a minority community, you get the least amount of attention and none of your wants are really ever met. And lets be honest, if innovating in that area were easy and the market was a substantial size, someone else would have done it by now. But they haven’t, because mobile is more important to their bottom line.

        • TopHatKiller
        • 6 years ago

        The jist of you’re post is not wrong of course, but are the chips in the tittle mobile? No.
        i-god innovates server lines. Because of competition.
        i-god reduces costs, increases profits, and laughs at desktop lines. Because there’s about bugger-all competition.
        Also: a funny definiton of HUGE is: skylarkish – pissall ipc iprovement, clock down, power up [or zippo change]… on the new 14nm – ‘Huge’ as in ‘my penis is Huge’.

    • BlackDove
    • 6 years ago

    I remember when people kept telling me how the L4 eDRAM cache wouldnt help CPU performance lol.

      • guardianl
      • 6 years ago

      The L4 cache takes up 82 mm2 of 22nm wafer. That’s an entire i3 CPU worth of die area, for what amounts to a small ~10% gain in some games and very little in most other applications. Looking at it another way, it’s basically a 5960X chip in die size, but they turned four of the cores into 128 MB of L4 (yes, the 5775C is technically two separate dies) which means you get 10% single thread performance boost in exchange of a loss of up to 100% more multi-thread performance.

      So, if you are looking to collect on a bet or something, I wouldn’t gloat too loudly 😉

        • brucethemoose
        • 6 years ago

        But it does performs better than the 5960X in quite a few games, as they’re often limited by a single thread anyway.

        Also, L4 is a nice way to increase performance without changing the platform at all. The 5960X and higher core-count Xeons need 4 memory channels instead of 2, which means more pins and traces, and they require a more expensive chipset for all the I/O. The 5775C’s cache, on the other hand, is completely self contained, and works well in a cheaper socket.

          • Klimax
          • 6 years ago

          And that’s Broadwell. With Skylake it will cache uncachable (aka I/O and other problematic cases)…

        • BlackDove
        • 6 years ago

        I realize that, but for workloads that rely on high single core performance these chips are excellent and dirt cheap.

        Its less than half the price of a 5960X so your comparison is ridiculous.

      • Krogoth
      • 6 years ago

      Some applications do like having more CPU cache, but there is a point of diminishing returns.

      Cache is more helpful in server and enterprise environments which is why chips gear for these tiers are loaded with cache.

        • BlackDove
        • 6 years ago

        Which is why people are saying these chips are great for gaming right?

        Lol the point is, the L4 cache helps with single core performance, and most games depend on high single core performance.

        Per core, even the E7 Xeons with 37.5MB L3 cache have a lot less cache than the 5775C.

    • terminalrecluse
    • 6 years ago

    5775C is still too expensive compared to it’s newer sibling the 6700K. They’re likely charging a premium due to the 128MB eDram.

      • NoOne ButMe
      • 6 years ago

      The premium is why you see it so rarely in laptops. Hopefully the 64MB version helps that out!

      Even having a “mere” 32MB standard across everything would be awesome. Well, maybe everything over an i3, something Like that.

        • terminalrecluse
        • 6 years ago

        I know it’s a blasphemous thing to be thinking about here, but being an apple fan, I was hoping for 4-5w TDP core-m skylake chips with eDram. Since I do less and less gaming these days, I really like the idea of a capable integrated on-die gpu in a low power envelope.

      • DoomGuy64
      • 6 years ago

      AFAIK, the 5775C isn’t a drop in replacement. We’d probably have to buy new DDR3L ram and maybe even motherboards?

        • mnemonick
        • 6 years ago

        If you have a Z97 based board, you [i<]should[/i<] only need a BIOS update and you can drop in the 5775C or 5675C. They also support 'regular' DDR3 because 3L is just low-voltage DDR3; same module design and pinout, and Intel has actually supported it since Ivy Bridge iirc.

          • DoomGuy64
          • 6 years ago

          But no Z87 support? It’s like intel wants you to buy a new mobo for every minor cpu update.

            • NoOne ButMe
            • 6 years ago

            How else can they keep their margins up as upgrade cycles are longer and cost of R&D for nodes increases?

            They need to keep stockholders happy. Probably Intel’s greatest weakness currently. Certainly a lot better than most companies greatest weaknesses!

            ——-

            To be more serious, Intel has deeply cut R&D and still is merely holding profit steady.

            Prices will go up as long as they continue to “upgrade” their P6 architecture. It’s just so well optimized already. The total team touching it was probably over 500 people for Broadwell. For very little performance gain at stock.

            It’s really expensive but at this point I don.’the see a good alternative for Intel.

      • Andrew Lauritzen
      • 6 years ago

      The 5775c die is actually much larger than the 6700K IIRC, due in no small part to the much larger Iris Pro GPU. If you add the eDRAM I wouldn’t be surprised if it’s actually cheaper in terms of $/silicon (not that that’s a very important metric for consumers, but just interesting).

        • auxy
        • 6 years ago

        Ironic perhaps that one of the largest GPUs Intel has ever made is in great demand among PC gamers… but not for the GPU parts. (*‘ω‘ *)

        Ahh, I really wish I had one. I’d do a whole bunch of testing with it.

          • Andrew Lauritzen
          • 6 years ago

          Eh, come for the EDRAM, stay for the GPU amIright? 🙂

            • auxy

            Probably not. LOL ( ;∀;)

        • chuckula
        • 6 years ago

        I did a quick pixel estimate of the 5775C and it was in the same ballpark as a 4-core desktop Haswell die (roughly 175mm^2 give or take). The proportions were different since Broadwell is closer to a square while Haswell is a more elongated rectangle.

        That is substantially larger than desktop Skylake, which is at about 122 mm^2.

    • kmm
    • 6 years ago

    Minor correction but if you’re talking about the eDRAM, that’s effectively L4, not L3. The L3 is 4 MB and 6 MB on the i5 and i7 desktop Broadwell chips. (4 MB L3 is weird for a desktop Intel quad core and probably reflects the mobile roots)

    And likewise by L2 you mean L3.

      • Damage
      • 6 years ago

      My bad for not catching that in editing. Fixed.

      • NoOne ButMe
      • 6 years ago

      Kind of surprise they don’t have a die without L3 and with eDRAM. They probably do enough volume to warrant the cost.

      Of course, dunno if the die space savings would end up being a positive ROI compared to now.

      Minor correction to your minor correction… it really is “eLLC” (i.e. an extended LLC) rather than “L3” or “L4” or so on which not only depends on where you start counting but also misrepresents how the cache behaves. 🙂

        LLC? Low level cache?

          Last level cache.

            That makes a bit more sense.

      He means they are black chuck. A cold dark soulless black.

        You know the thing about a chuckula, he’s got… lifeless eyes, black eyes, like a doll’s eye. When he comes at ya, doesn’t seem to be livin’. Until he bites ya and those black eyes roll over white.
