Core i7 "Haswell-E" Engineering Sample Pictured

8 cores will be cool, but what exactly are you planning to do that is going to bottleneck four channels of DDR3? O.o

Faster speeds are always welcome, if we all thought like that, we would never make any progress and be stuck on DDR3 forever

Speed isn't the only advantage though, DDR4 is lower power use, something I'm now looking for since getting my Q4 electricity bills

looks like i'm going to be selling my 4770k when the K version is released! best get saving..

Oh I am not saying that faster isn't better, however power aside I don't get why people are getting so excited about DDR4 for the enthusiast platform considering it hasn't even begun to get remotely near the limits of DDR3 yet, hell unless your doing some kind of fluid dynamic modelling you don't even need to populate more than two channels on X58/79 unless you need extra capacity.

At the end of the day if you can't do it with four channels of DDR3 you can't do it with two channels of DDR4 either which means for real world usage X79 won't be encountering memory limitations until some time after DDR5 hits the mainstream platform.

On that basis there's no point in me upgrading, l can still do everything on my i7 930 > game, photoshop. At some point l,ll have to upgrade so H-E + DDR4, may as well wait and get the latest Tech.

If you read the links, its quad channel DDR4, not dual channel.

Does Tri-Channel / Quad-channel make any difference over Dual-channel?

If you read my post you will see the dual channel bit is a reference to mainstream (Broadwell) which will be dual channel DDR4.

Does Tri-Channel / Quad-channel make any difference over Dual-channel?

For a quad core i7 no, for a fully loaded hex core dual channel becomes limiting during memory heavy synthetic use and tri-channel alleviates this, quad channel doesn't yet give any advantage apart from extra capacity, however it will last longer (four channels of DDR3-1600 are just as good as two channels of DDR4-3200 will be). For normal use, gaming, etc more than two channels are largely irrelevant apart from the capacity and tuning options they give (By tuning I mean you could if you wanted run four channels of DDR3 at lowish speed and super low CAS, and have better response time than a dual channel setup without sacrificing bandwidth).

Here is the paragraph I replied to from your post:

This is a thread about Haswell -E. Not broadwell. I took it to be obvious that the posters above are discussing the many benefits of Haswell - E, including ddr4, as an upgrade from their current system.

So once again, read the links where it confirms Haswell -E will be quad channel DDR4, and note we are talking about upgrading to Haswell -E, not to Broadwell.

Crucial is saying DDR4 early next year

The reason I put the comment in a separate paragraph was to indicate the reference between enthusiast DDR3 platforms and mainstream DDR4 platforms wasn't connected to enthusiast DDR4.

Yes I know all that, and no I never said otherwise lol.

As you seem to be having difficulty with this I will spell it out very clearly, current enthusiast platforms use four channels of DDR3 which is very over specified and basically only useful if you need >32GB RAM or if you are doing some kind of scientific research. Next generation mainstream systems will use two channels of DDR4. Two channels of DDR4 offers no performance advantage over four channels of DDR3, just power saving. This means that future i7's are not going to be bottlenecked in normal use by either two channels of DDR4 or four channels of DDR3. This means that the four channels of DDR4 coming with Haswell-E are nothing to get excited about as they will give no real world performance advantage over the DDR3 of X79 just energy saving.

Take my money already!

 

[Boomstick777]

Take my money already!

Haha, sums it up nicely

Was thinking Intel are obviously very smart, I bet these 8 cores coincide with newer games that start to utilize more cores.

PC's next year are just going to be ridiculously powerful 8 core Intel's and 20nm GPU's. Sick

Some of us will appreciate the memory bandwidth!

Skylake I await.

Have a feeling this will continue endlessly, as you cannot grasp the fact that this is not the thread (imo) to discuss the benefits of DDR3 vs DDR4. I'm assuming you maybe spent a lot on DDR3 memory recently, and are butt hurt over the idea ddr4 will arrive with Haswell -E, but please just accept it, and stop trying to talk it down.

It's also quite dubious that you seem to assume DDR4 quad channel performance, before there are any real benchmarks out. Yes, we can guess how much of an impact it will be, though the new platform may surprise us all, in one way of the other.

It would be similar to you coming into this thread, and debating the benefit of 8 cores on Haswell -E, compared to the current Haswell mainstream platform, with only 4 cores, as not all games don't fully utilize all 8 cores yet.

Please just accept that for many of us on the older I7 920, 2600K etc, we are excited about finally upgrading to a whole new level of performance, with double the cores, much more L3 cache, higher IPC performance, DDR4 speeds vs our older generation ddr3 etc

Boom and I weren't discussing that, we were discussing the advantages of Haswell-E and its X99 over X58/79, one of which is (on paper) quad channel DDR4 however I was pointing out it will make no actual difference in real world usage outside of scientific research.

It's also quite dubious that you seem to assume DDR4 quad channel performance, before there are any real benchmarks out.

If I was making assumptions yes, however it's actually quite easy to work out if you know how RAM works, DDR3-DDR4 is going to be a much smaller perfromance boost than DDR2-DDR3 was in the first place and for reasons I have already mentioned DDR4 in quad channel isn't really going to give any advantage in it's lifetime (before DDR5 hits) over DDR3 in quad channel.

I do accept that, I was just pointing out that DDR4 speeds are nothing to get excited about for a X58/79 user.

^^ Come on guys no need to argue, best thing about the PC is you can put whatever you want in it. If Ubersonic doesn't think DDR4 is much of an upgrade in his opinion, that's fine. I'm looking forward to DDR4 for the low power (1.2v), higher bandwidth, especially when it gets paired with APU's down the road. Thought this taken from Gizmowithatt's post is a good illustration to show some of the improvements.

 

[MooMoo444]

Can't wait to see some good overclockers get their hands on DDR4 and see what they can do with it

 

[tbh]

Skylake I await.

Skylake master race reporting in.

Hopefully by the time Skylake is with us DDR4 prices will have settled down to something reasonable.

 

[hakank68]

i am sounding like a noob but what advantages does the Haswell-E have over Haswell apart from DDR4 support, wich programs does it actually have a real performance effect on ?
