    Interesting point. Perhaps, because of that, Intel can afford to worry less about area-efficiency. That certainly seemed to play out in this current generation. Golden Cove is just a lot bigger than AMD's cores, which is ultimately why it can manage more single-thread performance. It's also why they needed the more area-efficient E-cores, in order to be competitive on multithreaded performance.

    I think it's not as bad as you say. The only business that's entirely off the table is Apple's, as they're the only device maker who's actually designing their own cores. The other device makers and cloud operators are using standard cores designed by ARM. As Apple has repeatedly shown, ARM's IP never seems to push the limits of what's possible. AMD will have its work cut out for it, trying to beat Qualcomm/Nuvia, but not if AMD instead focuses on the server market. Yes, Nuvia wanted to build server cores, but Qualcomm has expressed an intent to focus on the client market, for now.

    You're assuming Intel's fabs and design business stay under the same parent. I doubt they will, given how different their economics are. Design is a lot more profitable than manufacturing, but manufacturing is so capital intensive that it dilutes the profits reaped by the design businesses. Therefore, it makes sense split them up, as soon as the fabs are truly self-sufficient.

    I wonder if 14th gen will work with W680 motherboards. Probably going to stick with AM5 for next box, but would certainly spec out an ecc based 14th gen core box to compare with if it's compatible

    edit: it is, according to:



    now I have to decide on am5 vs 14th gen core. My current mobo is an WS series from Asus (P9D WS), so I'm quite partial to them.

    Not worth the upgrade to 14's over 13's, but if you're getting a new system or upgrading something really old or low-end, might as well pick the 14 if you're going for Intel.

    They are quite power hungry to achieve that performance, too, but desktops have a high power budget.
    Does this 14th Gen comes with a brand new efficiency core (small core) or they are just using the efficiency core that was launched with the 12th Gen?

    There are other reasons why they're less efficient than ARM-based ones. The x86 ISA is only part of it. The other main part is that they're optimizing area-efficiency more than cores designed primarily for mobile, where you're really trying to maximize perf/W.


    When they start selling CPUs based on these other ISAs, you'll see them still running at very high power levels, because market dynamics dictate that they maximize area-efficiency (sometimes referred to as PPA).

    Intel and AMD really need to make either a ARM or RISC-V CPU. The x86 architecture is at a dead end. Intel nor AMD can make x86 CPUs that are good enough to compete with the ARM-based offerings of Apple, Qualcomm and Nvidia.

    They're exactly the same. Here, you'll find a chart showing all 14th gen-branded CPUs are using the same die & stepping as either a 12th gen or 13th gen model.

    The only thing Intel changed were the clock limits, based on how their Intel 7 manufacturing node is maturing.

    On anything but lightly-threaded tasks, they're likely to be thermally-limited. The professional reviewers tend to use cooling setups far in excess of what most users have.

    Unless you care about efficiency or heat output. If I ran one of these CPUs, I'd have to use lower power limits (for reasons of heat & noise), at which point I might just be better off with the equivalent Ryzen.

    Thanks for the benchmarks, Michael. However, please get in the habit of telling us what CPU cooler you're using! These days, the unlocked CPUs run so hot that they tend to be thermally-limited, as much or more than anything else.

    Thank you for the benchmark Michael! No need to bother with upgrade. Let's wait for 15th gen.​

    The i7 is the most interesting chip of the 14th gen SKUs so far since it gained another 4 E cores.
