Intel this week revealed plans to discontinue its Kaby Lake-X processors. The chips will not be supported by the company’s upcoming X399 platform for high-end desktops, so initialization of their EOL program is not surprising. Interested parties will be able to get their Core i5/Core i7 processors in LGA2066 packaging for about a year, but they will need to order the chips by the end of November.

Intel on Monday announced plans to discontinue all versions (tray and boxed) of its Core i5-7640X and Core i7-7740X CPUs. PC makers and component resellers interested in these processors will have to order them by November 30, 2018. Intel will ship the final codenamed Kaby Lake-X chips by May 31, 2019, so technically interested parties have a year to buy these chips if they need them.

Intel introduced its Core i5-7640X and Core i7-7740X CPUs in mid-2017 in order to enable hardcore enthusiasts and professional overclockers to set overclocking records using quad-core Kaby Lake-X CPUs while taking advantage of the company’s latest HEDT platform. Usage of the X299-based motherboards with LGA2066 form-factor ensures better power supply to processors and thus helps to hit higher clocks. The plan was heavily criticized by product reviewers and motherboard makers since Kaby Lake-X CPUs require different voltages and memory kits than the high core count Skaylake-X CPUs. Furthermore, the launch of Intel’s six-core Coffee Lake processors in October made Kaby Lake-X products considerably less attractive.

    I've bought a lot of computers over my lifetime.

    I think I've only upgraded a cpu twice.

    A K6 200 to a K6-2 300, about twice as fast at quake2 because of 3dnow.

    A Phenom x3 to an x4. higher clocks and an extra core.

    That's it. Both times it was AMD. In every other case I bought a new board with the processor. Honestly this is the first year upgrading intel cpu's would be interesting. More cores, faster spectre/meltdown, etc. But - I'd be wanting to replace Sandy bridge/nehalem/haswell chips with something in the same socket and ddr 3 support. And that's just not going to happen. Same with Ryzen in AM3+. I could upgrade a few AM3+ systems with Ryzen for a meaningful upgrade but that's not an option.

    If they made a DDR3 ryzen or coffee lake board on the cheap I could get behind upgrading a few older systems. Having to buy DDR4 is the killer.

    Wow intel discontinue not even one year old cpu. No Specific upgrade path and support. Intel is milking even big time with their new cpu. How no one seeing this Reply

    Intel + upgrade path = lol
    Everyone knows intel doesnt provide upgrade paths, they do that in purpose to sell more chipsets.

    It makes sense because it was a useless product but try telling those that just bought these CPU's that oops you are now at EOL but hey we got some shiny new things for you to sink your money into if you want. SO yes I feel bad for those that bought these pieces of crap CPU's Reply

    Dear Intel,

    You guys really borked x299 in almost every possible way.

    1. Rush to market before MAJOR QA finished just to compete with unexpected rival = Check
    2. Release consumer chip that made entire HEDT line virtually irrelevant = Check
    3. Announce NEXT HEDT chipset less than a YEAR after x299 rollout = Check

    X99 was a solid a long-lived platform. But I'm thinking I'll be stepping away from your 'ol chipset shuffle for a while.... Cause geez, while I'm considering Coffee Lake for my upgrade, you've already revealed a replacement for Z370 as well!! ? Why would I buy an 8700k now when I am virtually certain Z370 won't be able to run your inevitable 8-core mainstream cpu?

    AMD and X470 is getting my $ this time.

    Sincerely,

    A Z77, Z97, X99 owner

    Why would you upgrade from an 8700K to the 8 core? What's the point? Reply

    Because the next gen of Intel CPUs won't be gimped by Spectre/mentdown patches, and I want the next fast i7. And... I'm ready to upgrade now because my current gear still has some decent resale value. Therefore, my soon to be spent money needs to be spent on a platform with at least the possibility of a CPU upgrade, it would just suck to put my $ into a dead-end platform. I upgraded both my z97 and x99 rigs twice each... X470 will give me that kind of breathing room. Reply

    Intel took what was a fairly clear delineation, beginning with the 5th generation parts, that if you wanted more than 4 cores/8 threads, you had to invest in the X-series CPU and PCH. For whatever reason, Intel simply pitched that logic out the window with the 7640X and 7740X.

    Intel had to know that without at least some sort of unique value proposition (more L3 cache than the 7700K, more PCIe lanes, an Iris Pro iGPU) that simply cherry-picking higher binned/clocked 7700Ks was not going to cut it with X-series users. Compounding the problem further, you could spend ~$60 USD more to move up to the Core i7-7800X, get 2 additional cores, a smidge more L3 cache and 12 extra PCIe lanes, which completley negates any cost savings when comparing with the 7740X.

    The takeaway for me is that I begin to wonder if Intel understands what kind of user buys an X-series CPU and motherboard. I see two distinct groups - gamers and professionals, who both shy away from committing to the Xeon line, for obvious reasons (general suitability to task, no Quick Sync, overall higher cost and lack of access to certain CPUs at the consumer level). Perhaps these distinct groups are one in the same, but the common denominator is that they want/need/desire something more than the top of the line Core i7 consumer CPU offers them.

    In the future, Intel should seriously consider eliminating the six-core SKU when it releases the next generation of X-series CPUs (8xxxX) and move to all Core i9 branding as a marketing differentiator. I also hope that Intel would resist any further Core i9 branding for non X-series CPUs. Having only one CPU - a 45-watt part at that - being called a Core i9 (the 8950HK) seems downright silly to me when you leave your most powerful Core-series CPU (the 8700K) as a Core i7 part.

    All in all, I see the Kaby Lake X-series failure as a lesson to be learned for Intel. I do not have any delusions that they will.
