I5 versus 17 proccesor

If you have a 1070 graphics card. Would an i7 processor give you a better experience than an i5 processor. And if so why? I appreciate any answer. Thanks

    Yes, the 7 is clearly two numbers higher than the 5. That's a rise of near 40%!

    If just gaming there wouldn't be much gains assuming the same architecture and clock speed.

    Of course an older i5 vs newer i7 would show some gains as would a newer i5.

    What have you currently got and what are you looking at?

    I7 = 4 cores and 4 virtual cores = multithreading, good for intensive processing like video editing, etc. Not much real world benefit if any for gaming however. I5 - 4 cores ( no virtual cores).
    Also I believe the I7 has slightly larger L2 cache, again no real world benefit as far as gaming goes.

    I myself however  run an I7 4820K and have been for the past three years or so, as I do mainly gaming on my PC I actually have the virtual cores disabled, I seem to get more consistent performance and slightly cooler core temps with it disabled ( I have my system overclocked to 4.5 GHz as well).

    My suggestion - if the money is no concern, go ahead and splash for the I7. If it is, you would likely be happy with the I5. However as others have suggested you might list your current system specs, depending on what you are coming from you may or may not see a real world benefit with a motherboard/cpu upgrade...

    Thank for your answers. It confirms what I heard before especially what dburne said.

    The i7 7700k (newest/best out)  can be had for a little over 300$ if you search for a deal. Not bad at all IMO. Of course you will probably need a new motherboard to use it as it is a totally different chipset. 

    I say go for the i7 if it's in your budget, but a gpu will always be more important for gaming

    I went for an i7, but from what I've read there is little to no difference in gaming performance. Just remember to get a k version so you can overclock it ;-)  Mines at 4.7ghz to a free 17.5% upgrade ;-)

    I hear amplifiers that go to 11 are better than ones that go to 10.

    Seriously, it's silly to say i5 vs i7.  There are i5 Kaby Lake processors which are better i7 Nehalem processors.  You really have to specify the architecture.

    I guess we should to assume you meant in the same architecture (e.g. Kaby Lake i5 vs i7) ? Still even there you have to compare specifics. You also have to divide it into mobile and desktop processors.  The biggest difference in general between i5 and i7 cores is that i7 has hyper-threading whereas i5 does not. That's true for desktop processor but not in general for mobile processors. For i3 they usually (or maybe always) don't have turbo.

    Here are some useful metrics for i3, i5, and i7 Kaby Lake processors

    Hi lemming u also make a good point. From what you said it doesn't seem u noticed a difference if u had an i5 in the past to compare.

    When I was building my VR rig, Skylake i7 6700K vs i5 6600K was generally considered about 5-15% quicker in game-style benchmarking. I bought the i7, but I should definitely have saved the £100 and got the i5, I've never come close to stressing it.

    For gaming is enough, maybe 5-10 fps less in games like gta V and The Witcher 3 (lot of phisics and AI on such games) but for a 1070 a i5 is fine. Dont buy kaby lake cpu.

    What is wrong with Kaby Lake? It's essentially Skylake with a higher base clock and some bug fixes.

    I wouldn't say there is anything wrong with kaby lake, just don't upgrade from skylake.

    I would wait for zen before making a decision on cpus.

    @Percy1983

    Does the OP have skylake already? I did not read the OP saying what kind of CPU he/she has already.

    Nope not sure what they have or what they are thinking of so my last comment is general advice.

    I bought an i5 6600K.  O/C to 4.6 ghz.  Works great with games.  Really not a lot of games takes advantage of the i7 6700K's multi threading.  If you did CAD and Video editing and such.  Then You would want a i7 CPU.

    The 90 USD Kaby Lake G4600 Pentium processor may actually work out okay. It's dual core with hyper-threading. I think it's the first Pentium processor with hyper-threading. The low budget Pentium and Celeron processors don't support AVX or better but they do support SSE 4.2.  But in reality AMD processors don't really have AVX either. They have the instructions but in most cases it's emulated as SSE twice.

    I have to overclock my i5 processor to get better tracking at the moment.
