I7-4770 vs. i7-4771 vs. i7-4770K - Which has missing instruction set vs. the other 2?

  1. I've got my build together to use a Socket 1150. I have read that one of these CPU's does not have the full/latest instruction set vs. the others. Overclocking is not important to me but I will buy the "K" series if it has the fullest instruction set.

    Can anyone enlighten me further on this?

    Thanks.

    I think one of them has an extra instruction set that is not used much now but will be.

    That's it - the links you posted helped.

    The 4770K is missing some virtualization and TSX and VPRO instruction sets.

    Thanks. That's what I was looking for but got a little lost on the Intel website.

    Why is it you think you need these Advanced Technologies?
    • Intel® vPro Technology
    • Intel® Virtualization Technology for Directed I/O (VT-d)
    • Intel® TSX-NI
    • Trusted Execution Technology
    If you didn't know how to check which ones had them, chances are you would never need them. And the fact that the 4770K does not have them, only shows they are not that important anyway. I personally wouldn't select a CPU, based on the absence of a these technologies.

    Why wouldn't I want them when the price is almost identical? The last thing I want to do is pony up the same amount of money for a processor with fewer features than its sibling. Perhaps I will want to sell it on my next upgrade cycle.

    Do you make a habit of trolling threads to add unhelpful condescension in order to boost your post count? Is this making up for some other inadequacy in your life?

    Maybe because you will never use them. I'm trying to understand why. As for trolling, that is my business. Good day sir, buy whatever the **** you want, I honestly don't care after that comment.

    Actually... you may want to research these "missing" features a bit before making a decision. On the consumer end the K model is the one you will want more and on the enterprise end the non-K models are more desirable. At work I prefer the non-K models because when configured properly you can do things like use VNC Pro to remote control the machines before the OS even boots. I can see and capture bios settings and even have control over power settings without the need of traditional wol tools. At home I only buy the K models because they are unlocked and allow for easy overclocking.
