Single dGPU Gaming

For our single discrete GPU testing, rather than the 7970s which normally adorn my test beds (and were being used for other testing), I plumped for one of the HD 6950 cards I have.  This ASUS DirectCU II card I purchased pre-flashed to 6970 specifications, giving a little more oomph.  Typically discrete GPU options are not often cited as growth areas of memory testing, however we will let the results speak for themselves.

For some reason we see a small dive in terms of Tomb Raider minimum FPS numbers.

    Thanks for the review.

    But with all due respect to this site that makes one of the best hardware coverage in English, I'm kind missing interesting stories lately. The late 2013 MacBook Pro, some Windows tablets, GPUs, CPUs, operate systems... anything.

    As fat as real world performance is concerned, RAM impact is so negligible for the vast majority of users that this sort of article ends kinda of... boring.

    Yet again, thank you for the article. I meant no offence in any way!

    Definitely agree with this one... Reply

    I have to agree that these memory articles are uninteresting and not particularly useful. As others pointed out -- and these articles confirm -- the real life difference between decent DDR1600 and super-duper ultra-high-end RAM are virtually non-existent. One article summarizing that would be more than enough. Reply

    Ian Cutress,
    Hello again! This is another article stating 1866/C9 being the minimum for Haswell and to avoid 1600 or less. Even going so far as to say, "Any kit 1600 MHz or less is usually bad news."

    However, this ignores 1600/C8 modules. The 1600/C8 score a 200 on your Performance Index at stock timings. This is at your recommended 200 level. There are several kits of 2x4 GB 1600/C8 on Newegg that have memory profiles of 8-8-8-24 at 1.5v. I'll repeat, these 1600 8-8-8-24 1.5v kits score 200 on the Performance Index and hit the current memory sweet spot for most people of 2x4 GB. This scores very close to the 1866/C9 kits which have a Performance Index score of 207.

    The reason I bring this up is that the 1600 8-8-8-24 kits are often less expensive than the 1866/C9 kits and offer essentially all of the performance.

    I enjoy reading your articles and appreciate how active you have been lately!

    This is why I am sticking with my DDR3-1600/CL7 memory until DDR4 hits mainstream. PI = 228 which is faster than 1866/CL9. Reply

    Ian, any comment on 1600/C7 or 1600/C8? Reply

    "In this graph the x-axis is the Performance Index of the DRAM, and thus a PI of 200 can be 1600 C8 or 2400 C12."

    This article does not ignore 1600/C8 modules.

    hi, i'm new to ddr3 lol. Re: haswell & 1600/C8, anandtech's intel gaming rig pairs an i5 with 1600/C9. Is this bc it's the cheapest build so not worth the price/performance, or is there really something bad about mixing haswell with anything slower than 1600/c8?
    thanks a bunch

    And another incompetent article from Ian... Didn't even bother to read comments to the previous one to correct errors...

    Oh, and my IP (range?) is still blacklisted by stupid spam filter. Of course, I probably not love my job enough...

    Lol maybe it should spam filter depending on the job happiness scale, seems legit. Reply
