    When will i7 4790K stop being manufactured? should I sell i5 and get i7?

    Toying with idea of perhaps getting one before can't buy one new or that they're in such short supply/inventory with etailer that they're horrendously priced.

    I was wondering if a mod can correct error in my spelling of title, thanks.

    You should be able to correct it yourself, just edit then advanced or whatever.

    They've probably already stopped manufacturing them.

    Re: When will i7 4790K stop being manufactured?

    Cheers.

    Hmmmm, really don't wanna part with my i5 4690K as clocking so well and having 0 issues. In my estimate selling it I'd lose perhaps £7 off purchase price, even taking ebay/paypal/postage fees into account. This low loss is making it tempting to buy i7 4790K.

    The whole DX12 thing is making me think if I grab a i7 4790K I can hold on to setup like I did with my Q6600 for donkeys with just GPU swap outs. Part of me thinks but will there be a performance enhancement or not from DX12 to justify it? if the i5 4690K delivers enough perform under DX12 I may not need i7 4790K or justify the cost of change?

    Another concern I have with i7 4790K swap is temps that HT will introduce, so far the Archon SB-E X2 is perfect with 4.9GHz OC. It touches max 74C x264 (48 loops/8hrs), RealBench 8hrs climbs to 78C due to the GPU being under load when using stress mode, F@H 77C, gaming is pretty low.

    When I equate the % of price I'm paying above cost of i5 4690K its making me back down from purchase. I calculate a 59% increase and probably more if I have to swap out cooling. If I back down from OC'ing I don't see the point IMO of swapping as the higher clock rate may just be enough or beat a poor clocking i7 4790K.

    I can't see a 4690k running into performance problems for at least a good couple of years yet. I am certainly not getting rid of my 4670k anytime soon.

    Re: When will i7 4790K stop being manufactured? should I sell i5 and get i7?

    I doubt HT will make a huge amount of difference to DX12 performance tbh, the real benefit of DX12 is reducing the single threaded load rather than introducing a heavily threaded workload. Plus, developers will still need to code specially to get the benefit, so there's a reasonable chance that a lot of DX12 games won't actually benefit that much from being DX12.

    An i7 shouldn't produce significantly more heat than an i5 - you're powering exactly the same number of transistors, after all. So I think temps/cooling should be your last concern in terms of the swap.

    For my money, it wouldn't be enough benefit to swap just for gaming. If you perform other heavily-threaded tasks on a regular basis, like video transcoding or whatever, it might be worth it, but just for DX12? No way.

    And to add, if you do want to swap, just wait for a second hand one from someone else going to a newer system. It's not some golden chip that second hand prices are going to increase with falling supply - prices will likely just keep falling. A better bargain would be a second hand 4770K

    My brain thinks that, but it also thinks opportunity to sell with minimal loss.

    This was what my brain was understanding from some threads/info I'd read as well, some of the things I read went over my head .

    Not gonna state info I've read by owners in OC threads where they see drop in temps from HT off. In Custom PC issue 132 Devil's Canyon launch review they OC i5 4690K & i7 4790K to 4.8GHz using 1.33v for both(perhaps a typo? or to compare like for like?). They state T delta 49C on i5 and 59C on i7, usually they use smallFFT Prime95 for such tests but not stated in article, Corsair H80i used and test rig same.

    No video transcoding at all, light office/web use, mainly gaming when I get the chance (1hr or so max a day if that). The £/performance is whats stopping me, I can't see an i7 giving me 59% more performance than the i5.

    4770K not an option IMO, I don't delid so prefer the 4790K for TIM improvement(if there was any??). Shockingly second hand prices usually tend to be not that cheap IMO. Link:- Recently sold listings i7 4770K, currently Amazon.fr £223 for a i7 4790K.

    When I was building my i5 4690K rig I did think just get an Ivy or Sandy bridge via 2nd hand route, once I viewed prices I thought forget it.

    My cost:-

    i5 4690K £140 (average of 2 I bought, then sold 1).
    Asus Maximus VII Ranger £97.39 (after selling Asus Front Base panel which came FOC with mobo).
    Kingston Savage 16GB kit £95 (price was high in Jan 15).

    All of above new and Archon was 2nd hand £13.50.

    Would your old setup have lasted any longer if you'd swapped out your Q6600 for a QX6850? Exponential growth is a great leveller and buying more performance you're not going to need for years is a waste of money.

    Re: When will i7 4790K stop being manufactured? should I sell i5 and get i7?

    That's not the same as i5 4690K vs i7 4790K, only reason like I said is 4 threads vs 8 .

    I couldn't see any difference like that between Q6600 vs QX6850 , Link:- http://ark.intel.com/compare/30789,29765

    My Q6600 stock runs 266MHz x9 to = 2.4GHz and 1066MHz FSB, when I OC it to 3.555GHz I used same 9x multiplier but 395MHz = 1580MHz FSB, was I concerned by QX6850 1333MHz FSB (333MHzx9), no.

    The Q6600 G0 had a Tcase of 71C vs 64C, so would I go for a QX6850, no. IIRC the QX6850 didn't really OC more than a G0, as always with any CPU OC'ing ability it's pretty much silicon lottery.

    Yes some steppings, etc can be better but OC ability was not the reason to consider a i7 4790K, not even the cache size IMO, it's just the HT aspect.

    Comparing FSB (Q6600 vs QX6800) to thread count difference (i5 4690K vs i7 4790K), is not the same IMO.

    I guess I didn't or don't understand what DX12 will bring, but pretty sure after all the enlightening posts here that I shouldn't be considering swap out. TBH I'm not even sure when I will start to run Win10 to use DX12.

    That is true, it's inferior. A clockspeed boost helps almost all applications while SMT (hyper-threading) is much more patchy.

    I kind of agree that you might not use an i7 to it's full potential - heck, I've spend a good amount of time with my 4790k playing flash games But nonetheless, I would upgrade to the 4790k because WHEN you do decide to upgrade, you won't have to buy a new motherboard for something like a Skylake... especially given the difference between it and the 4790k won't affect anyone majorly.

    I'm still running a i5 2500k at 4.6ghz, No problems yet, Plan on upgrading in 2017 with cannonlake perhaps.

    Sounds to me like you're looking for a justification to scratch the upgrade itch

    HT is unlikely to be relevant for gaming even with DX12 - certainly not the sort of difference that would reflect the difference in cost, anyway!

    The 4790k should be fine for a couple more years.
