i7 or i5? HT worth it?

    To be honest, while that list shows applications that have been designed to use "multi-threading", it doesnt necessarily mean there will be noticable gains of HT compared to a regular multi-core CPU. Also that list doesnt list WHICH versions of those applications are needed for gains. Excel is one example. You need to use the lastest version. Older versions are single threaded. And for gaming? Well, as we have seen many times, going from single core to dual core means great benefit, esp. in reducing lag frames. But dual to quad is marginal. And quad to quad with HT makes no noticeable difference.

    So let's be honest. If this guy is deciding on investing his last $100 on a CPU with HT or a better GPU... then go for the better GPU :pimp:

    i disagree, my 3770k creams the 2600k i had, well i agree on the oc temps, but when you are only using air i can clock 200mhz down for the same performance

    Well i say i7. Why? Probably more future proof.

    only way a CPU is future proof is to swap it with another since the core isnt modular. the 2600K doesnt lead the 2500K by too much so it negates having to use HT honestly.

    Yes, the extra logical cores can help under heavy VT workloads, all the K edition chips support VT, however the non-K and SB-E chips support VT-d which improves virtualized I/O performance.

    Basically, anything that can utilize more threads will and anything that doesn't won't have a problem because the i7 is just as fast as the i5 thread-for-thread. However the extra cache and logical threads improves performance over 4 threads.

    Couldn't agree more. I got my i7 3820 because I run a number of VMs, I'm in need of re-encoding all of my video to the same format (which the 3820 can do reasonably unlike the old Phenom II 940,) and because I wanted an Enthusiast platform with a better upgrade path. However I looked at a number of reviews before hand and in almost every case for video games, the i5 is just as good as all the faster solutions with more threads and more cores.

    If you're going to game, go with the i5 and invest that money elsewhere. Also honestly, part of the reason I got SB-E was my refusal to buy a mainstream platform after having to buy decent hardware for so many years I just wanted something a little better. It's up to you, the i7 definitely won't disappoint but the i5 should be enough.

    Ok, but when you can get a bump of 400mhz more out of the 2600k due to temperature tolerance(at the same max load temp)....

    Sorry I'm still having a hard time understanding why/how Ivy is "that much greater" from an overclock standpoint.

    In SOME programs it is but the average difference between IB and SB is around 200Mhz but that it. If you already have a CPU similar to its performance then IB is not needed but if you are coming from say AM3/775 then IB would be a good choice but this statement all goes to budget and what you get find for the right price.

    Real man use real cores, wait .. who said that. Oh damn. Anyway, most games only use 1-2.5 cores and even then they suck doing so. Safe the money for the next upgrade or party some, makes more sense.

    Many years ago i was 15 too, i understand what u are going through, tough times...

    Ivy has more features (ie native USB3, PCI Gen 3 and whatnot), and after OC has the same performance as the SB counterpart when OCed... Yes it won't be as high of a clock but since Ivy beats SB perf per clock wise, it'll even out.

    I see no reason not to go 3570K over 2500K

    Id go with the HT cpu anyday of the week.

    I was kicking it last night and turning off HT and running certain programs and Yup, HT all the way.

    Here watch this video, the guy is kinda a dip but he makes things easy to understand HERE


    Id wait for now. Wait for a new revision on IB and grab a 2500 or 2600K for now.
    Besides pci-e 3.0 was shown to be a joke.

    he said it's used for day to day and gaming, HT won't help much for those, specially not 100$ worth

    my guess is pcie gen 3 is going to help in the future, not for now

    I use my machine for day to day also gaming so whats the big deal? Im more then happy with my cpu and have a board that supports IB but why waste the cash on a earlie adoption.

    yet you want to waste money on HT? The difference between 2500k and 3570k is really small, specially compared to the diff between HT and non-HT version of the CPUs

    It's more like an ECU remap, because it's using unused resources. When a CPU is running at 100% on all cores without hyper threading, there are parts of each core that aren't being used even on modern super-scalar CPUs. HyperThreading adds logical threads that use these unused resources to churn out a little more horsepower. The extra cache is to try to keep system memory from getting hit as often with the extra threads on the CPU.

    Thanks, and thats why I love HT.

    I used to be an Amd fan but not any more... I had 4 core, 6 core, 8 core and nothing comes close to this Intel cpu :rockout:

    Anyways I guess It's up to one's budget on what they buy. Me Im sticking with this settup for a few more months till Intel revise there IB proc :D

    I have 2x 2500k's @ 4.7ghz and 1x 2600k @4.5ghz. I can tell you now that I would not trade my 2600k for either of my 2500k's. Don't get me wrong and I'm not try to start a flame war with other 2500k owners... If you don't have the money to get a 2600k then the 2500k is a great chip, but if you can afford a 2600k or ib then get it. People that tell people to only by such and such because that's all you need are full of horse shit! You're on a tech forum we want more than the avg pc user.. better is always better! :toast:

    What does a Holy Dam have to do with this? :confused: I think we have all given him plenty of answers. Telling him to buy a chip that's only 100 doll hairs more is us showing him our epeens? If we were doing that we would have said, "Zomygod get a i7-3960X Extreme Edition".. I think you need to learn what an epeen is... like I stated before if he has the money.. Why not get the chip with HT?... What if he doesn't plan to upgrade for a couple of years?? spending that little extra is worth it. :toast:
