    DDR4 benefits over DDR3?

    What are the benefits really except for lower voltage?
    Also i thought it was pointless having faster RAM (unless APU) as it wont provide that big a benefit.
    Thanks

    Re: DDR4 benefits over DDR3?

    Not much for most people right now.

    I've yet to see a benchmark that shows major benefits of DDR4-2666 or higher. Perhaps it helps some number-crunching such as decrypting encoded messages?

    You can have up to 64GB of it though with a Z170 board. In 5 years time that probably won't sound so ridiculous, but by then we might be using 4x32GB HBM or something else.

    Re: DDR4 benefits over DDR3?

    Thanks, i dont see the point really either and 64GB is kind of stupid these days. 32GB is the max and only if you are a creationist (obviously servers may require more than 32) and 16gb is plenty for future as well as overkill for gaming these days

    Re: DDR4 benefits over DDR3?

    The problem is DDR4 has really slow timings at the moment. High end DDR3 is slightly faster for gaming on than most DDR4.

    Right now the best combo is 4790k or 5820k with DDR3. But in the real-world, anything from sandbridge and up makes almost no difference in gaming. The difference between a 2600k and 6700k is less than a handful of FPS when over 100fps.

    Agreed, no real advantage atm for gaming, DDR4 is also expensive !!

    No to mention price as others have said, I'll be sticking with DDR3 for now as well. Price and timings will improve eventually, then It'll be time to take the plunge for most of us.

    Re: DDR4 benefits over DDR3?

    prices are coming down, you can get 16g for under 100GBP, I know ddr3 is still cheaper a bit but there isnt too much of a gap. In terms of performance I am also interested in what the benefits are, but you cant expect having a large performance boost in gaming from RAM. The difference will be very subtle since gaming's most prominent bottleneck remains the gpu of course, with second place way behind being the cpu.

    From what I've read so far, there is no advantage of DDR4 over DDR3 at the moment........

    u have the advantage in high req apps like 3d development and other ram asociated apps, also u get quad channel

    Re: DDR4 benefits over DDR3?

    As the others have said, it won't offer much benefit. Basically, if you're building a new rig, might as well get skylake and DDR4, if not just keep what you have -- both the processors and new ram are nothing to write home about.

    Re: DDR4 benefits over DDR3?

    It'll be a necessary pill to swallow on X99/post-Z170 (and probably AM4 once it comes out) so if you have the choice to either go DDR4 or DDR3, you might as well jump on board DDR4 now considering the pricing isn't too bad (cheaper in the long run than buying DDR3 and then DDR4 when you come to upgrade)

    Re: DDR4 benefits over DDR3?

    Hmm Linus does a good comparison video on both

    https://www.youtube.com/watch?v=utWnjA4NzSA

    Conclusion : If you have a CPU with a low amount of cores stick with DDR3 as its alot cheaper and you wouldnt benefit much from DDR4 on the other hand 6 - 8 core CPU's i think its a requirement to use DDR4.

    I'm not aware of any desktop platforms where you get to make that choice; it's either DDR3 or DDR4 depending what CPU/platform you go with, unlike the DDR2-3 transition where you could choose in some cases.

    There are s1151 motherboards that take DDR3 memory - skylake has a hybrid memory controller and can use either DDR4 or DDR3L. Much like when AMD moved over to DDR3 and people could use AM3 chips in either AM2+ boards with DDR2 or AM3 boards with DDR3...

    Re: DDR4 benefits over DDR3?

    Oh I'd completely forgotten about that!

    Last time I checked DDR4 prices were near DDR3 anyway so if you're buying new there's little reason not to choose DDR4. Plus DDR3L tends to be a bit more expensive and hard to find in the desktop DIMM format.

    Re: DDR4 benefits over DDR3?

    A couple of years from now DDR3 will be low volume and more expensive than DDR4, so if building a machine now I would tend towards the newer DDR4 for the sake of possible future upgrades.
