DDR4 Haswell-E Scaling Review: 2133 to 3200 with G.Skill, Corsair, ADATA and Crucial
by Ian Cutress on February 5, 2015 10:10 AM EST2x GTX 770 SLI Gaming
Next up is a pair of MSI GTX 770 Lightning graphics cards in SLI, which may be more akin to the typical Haswell-E system. Our goal here is to provide enough frames for a full on 120 Hz or 144 Hz refresh rate, ideally at the minimum frame rate level in modern games while still attempting maximum quality settings at 1080p. Even for this system it will be a hard task, and it will be interesting to see how the different memory configurations help with this.

Conclusions at 1080p/Max with two GTX 770s
Similarly to the single GPU arrangement, the only deficit worth mentioning is that of the minimum frame rate in F1 2013. Here we see 114-115 FPS on all the DDR4-2133 C15 kits, compared to 124-126 FPS on everything else except DDR4-2400 4x8 which had 120 FPS. This is a bigger 10% boost from choosing something other than the JEDEC standard.

To back up some of what i said here is a few linksI3 2100 matching 2500k@4ghz in dirt 3

Arma a cpu bottlnecked game where a 2600k@4.3ghz with 2133c9 ram is faster than at 4.9ghz with 1600c11

Xbit ddr3 review looks a bit different to yours...

And not one of those is using ddr4...Dasa2 - Friday, February 6, 2015 - link
Nope hence why I would like a decent review site like anandtech to do a proper job of there ddr4 reviewIm not expecting a big of a difference from higher speeds quad channel ddr4 by comparison to what can be seen in dual channel ddr3 but even there haswell ddr3 tests showed jack all due to the same problem with there tests so how can we know for sure

You're correct, you made your points, so of course someone without many watts currently on display there said something silly, as usual being stupid pays off and those not dumbed down to base below average levels suffer the frustrating beyond belief consequences.mrcaffeinex - Friday, February 6, 2015 - link
The problem is that we currently do not have a non-enthusiast platform available that supports DDR4. The new X99 platform is also running quad-channel, so the best comparison to a prior platform would have to be using X79 (attempting to keep as close to apples to apples as possible). The point that can be taken from this article as it is right now, is that you can skip buying insanely-priced DDR4-3000+ memory because your X99 rig will probably not perform noticeably different with DDR4-2133.As the process matures and more systems adopt DDR4, then you'll be able to do a better comparison across multiple performance levels, but as it is right now, if you're buying into X99, you're buying a high-end CPU. I look forward to the extensive comparative tests that you have mentioned, but I do not see them happening until either the mainstream platform (LGA 115x) is running DDR4 or AMD has any offering that supports DDR4.

Unfortunately you cant take that from this article as the gaming tests wouldnt show if there was any gain from faster ram even if it did boost cpu performance by 15%These tests were worse than a complete waist of time from a gaming perspective as they could be very misleading
At a guess i would expect to see somewhere between 3-7% difference going from ddr4 2133 to ddr4 3200 at the same timings although most of that gain will probably be between 2133 and 2666 happy to be proven wrong though
Sushisamurai - Friday, February 6, 2015 - link
although I agree it would be nice to see the impact DDR4 timings and speeds on CPU bound games, I unfortunately don't see the real world application to it. With DDR4, we're working on Haswell-E, which already has a lot of compute power - if we were to run into any CPU bottlenecks, wouldn't it make more sense to spend more of the budget into the CPU instead of RAM? Unless, you had enough money to buy top CPU and top RAM, then the point becomes quite moot no?Dasa2 - Friday, February 6, 2015 - link
Depends how big the gain is from faster ram doesnt it and we wont know that until its tested properly with the ram speed compared cpu speeds toTesting cpu or ram performance with gpu bottleneck games is a waist of time unless your AMD trying to sell fx8150...
The only cpu limited games at this stage on Haswell-E will be the ones with bad multithreading support so spending a heap more on the cpu for extra cores from the 5960x wont help
What will help is spending extra for a better overclock and maybe faster ram but how far do you go

> The games you chose to review are so badly GPU bottlenecked its sad.That's why they were running these games at reduced resolutions and IQ settings, Einstein.
What game should Anandtech benchmark that is NOT GPU LIMITED - Quake 3 Arena?
Dasa2 - Friday, February 6, 2015 - link
They shouldnt reduce detail settings just no aa and resolution to 1080p while running a gtx980 or two (r9-290\gtx970\gtx780oc minimum)But with the likes of dirt 3 even if they do reduce detail settings its still gpu bottlnecked
Arma\Dayz are some of the only games that can be cpu bottlnecked with a single gtx770
Dying Light is very demanding on both cpu and gpu

There is a lot of games that can be a bit of a blend of cpu\gpu limitation with enough gpu power although most of these will run 60fps fine on a 5820k a fair few of them wont do 120-144fps
http://translate.google.com/translate?depth=6&...
As they are a blend there limitation can vary from one part of the game to the next for example testing BF4 SP although easier to get consistent results will be far more gpu limited than MP some levels will also be more gpu limited than others
This is why i suggest putting different models and clocks speeds of cpu in against ram speed results so that people can see where the limit really is and where money is best spent
