What makes you think Intel can't let them go for less if they need to? They charge what they do because they can, not necessarily because they need to. Sure maybe budget tablets are probably a no go but if Intel clean up in other segments then I'm pretty sure everybody else is going to feel the pinch if they're confined to dirt cheap models. Tablets could be a way to subsidize more lucrative markets, the same way a company like Nvidia fund their HPC aspirations with lower margin mainstream GPUs. The only question Intel need to ask themselves is whether or not it's worth using their limited 14nm fab capacity for. The problem isn't whether they'll make money or not, it's whether they'll make enough to justify it

If Intel lower their prices it affects their base strategy, they need to reduce R&D and other investments. Intel is a huge company and needs high margin to stay in the lead.
Please understand that people buy tablets with 20$ SOC instead of budget laptop with 70$ SOC/CPU, this transition won't kill Intel but it will give them less money and that is of course a problem for them.

Its still a parallel bus. Point to Point limits it to 1 DIMM per channel. So a dualchannel DDR4 board will only have 2 sockets.
True for lower-end consumer boards but not for server/HEDT and probably the higher-end Skylake DT boards. It will be possible to use several DDR4 LRDIMMs on one channel. These Load Reduced DIMMs use active buffering so that they have bus load characteristics of a single DIMM even when multiple DIMMs are present on the bus. Really no different from DDR3, where you already need RDIMMs or LRDIMMs for using many DIMMs per channel (e.g. IVB-E up to 3 DIMMs/channel, IVB-EX up to 6 DIMMs/channel).

Buffered DIMMs are usually slower and more expensive the last time I checked (of course, that was for non-critical server DIMMs wo/ECC). I think DDR4 is going to be available with up to 8 GB DIMMs, from the start, and eventually 16 GB - so I don't think having only 2 DIMM slots is going to be a problem (especially at the low end where 2x2 or 2x4 will be the norm) - IIRC.

Right. LRDIMMs and digital switches, like this:

In the data, we also saw the first named after Intel Broadwell platform, on the same platform as the 14nm process, Intel will replace Broadwell with Braswell, and import DDR4 memory. Intel in Haswell-E / EP platform has been imported DDR4 memory, but in general Broadwell platform will remain in DDR3, Braswell platform until 2015 Skylake processor.

Braswell might be the name for Broadwell DDR4. Initially it seems DDR3 only and later Braswell with DDR4.


This document also reveals that the successor to Broadwell, on the Skylake microarchitecture, will be called Braswell. Braswell will be using the 14 nm process node and will support DDR4 RAM. Skylake and Braswell are expected out in 2015.

Braswell based on Skylake makes no sense. I think Braswell is Broadwell with DDR4.

You mean 32GB, right? 8GB DIMMs will be fine for notebooks, but 16GB DIMMs need to be available before it will make sense to move to DDR4 on desktops, with only 2 DIMMs maximum.

Well, for the vast majority of consumers, 8 GB is all they are going to need. I'd be fine with 16 GB, as my usage is typically around 8GB, and only runs higher when I'm testing something in a VM. If I go with Haswell-E on an x99 board I may shoot for 32 GB, just to be future proof. I'm sure I'll have my next desktop for 5 years.

Anyway, the largest actual announcement I've seen so far is for a 16 GB DIMMs. I'm sure larger ones are coming, but it'll probably be a while before there are consumer variants (first ones will probably be for servers - Registered/ECC).


Dang, I posted another post right after mikk's last post but it isn't here now

Don't think this 'braswell' is replacing broadwell...skylake replaces broadwell on the 'core' line.

I don't think Braswell replacing Broadwell either, they just call DDR4 models Braswell for better differentiation.

There will be 32 GB DDR4 sticks from the start. Of course that kind of capacities will be targetted for server products, rather than for consumer market.

http://wccftech.com/samsung-launch-ddr4-32-gb-ram-memory-sticks/

I'll bet we'll see at least 128 GB sticks before DDR4 get replaced by newer standard.

Didn't find that one when I searched. Thanks for the info!
I don't think I'll go higher than 4x8 GB, but hopefully there will be faster 8 GB modules by the time I jump in (beginning of 2015, because I like to go for second gen motherboards which have the kinks worked out).

Braswell based on Skylake makes no sense. I think Braswell is Broadwell with DDR4.

I read elsewhere on vr-zone that Skylake will come out first for Workstations and Servers - though it looks like it's only for single socket quad core :| So that would make sense, as Braswell will probably still serve the mobile market (and desktop?). I would think OEMs might want LPDDR4 to be available by then, for ULV-Y based notebooks.

If these rumors are true, I wonder what's up with Skylake for the desktop and mobile? And, when will Skylake-EP be available?

Oh, here's the link.

Skylake will come out first for desktop/mobile. And roughly a year later for workstations and servers. (2016/2017 timeframe).

I see a desktop Roadmap with Skylake placed within 1H 2015 in your link.


And roughly a year later for workstations and servers. (2016/2017 timeframe).


Entry Xeon E3 line shouldn't come later than desktop. Skylake-E, -EP, -EX of course come way later.

That makes sense based on the chart, I guess something got lost in translation visa vi the text.

I was wondering about SL-EP because I read a rumor that it would come out a year after the desktop CPU, which would place it ~18 months behind HW-E (which I think was the case for IB-EP as well). I'm still dying to know if HW-E and SL-E will both work on x99 motherboards and fit in the LGA 2011-3 socket. 14nm may be a big deal for since it seems like Intel is looking to up their game, performance wise, on their server line (while still lowering power consumption compared to 22nm). Or to put it another way, it's looking like FinFET 2.0 really rocks on perf/watt*!
