My work laptop has 64gb ram and I'm stuck with 16gb on my retina . I adore my retina but it's really lagging. I've had 32gb on my laptop since 2012
Playing devil's advocate here, .. what does Apple have to gain by blowing smoke?apple is really blowing some smoke.
I really doubt more ram will crush the battery time. We've had Dell precisions and thinkpads at work and I've tried them with 2 and 4 sodimms and the battery time was pretty much the same.
They already f'ed up the battery life on these by not being able to include the larger battery that they had designed for these new cases.

That won't happen for another year or two. Kaby Lake, like Skylake, can only use 32 GB if it uses desktop RAM. If Apple offers a laptop with 32 GB this year, it will use desktop RAM.using 32GB on the 2016 would have meant Apple delaying their launch and using the CPU that could have supported 32 GB laptop RAM
Haha!Technically, Samsung is the one blowing smoke (and flames)

Mobile RAM is designed to use less power.Whats the difference between mobile RAM and desktop RAM?

Not incredibly far, I'm regularly using 12gb doing illustrator and photoshop work. Future versions, as the ability to display complex graphics grows, will likely use up even more resources.Lagging in what, exactly. What do you need the 32Gb for? I'm almost certain it wouldn't fix your lag.
It's for people running VMs or doing a lot of video. It has nothing to do with lag, and in 2017. 16Gb is quite enough for almost everything (other than some very specific tasks, then you're out of luck).
But people love higher numbers, and MacRumors forum members are obsessed with 32Gb RAM. In the outside world, 16Gb on a new MBP will get you far.

Right now, 16gb will work. Give it a couple years, who knows? It's about future-proofing and ROI rather than outright specs
While it's true I haven't encountered any slowness, and I know that programs allocate ram whether or not they need it, I'm just concerned about the amount of time I have before I start to get slowdown. I have both open (with multiple tabs and projects) at the same time as I do mail, safari, finder with multiple tabs, etc.Nope, Photoshop and Illustrator will use ALL available RAM but tests clearly show there is no increase in performance with more than 8Gb RAM even with large files. 16Gb RAM will make Photoshop run at 100% efficiency for at least 5 more years.
I don't want you to take this the wrong way, but I don't think you understand how RAM works. You won't need more than 16Gb for Photoshop or Illustrator for a long time.

Interesting, thanks for the reply.When a program is not being currently used, its data will be either compressed or evicted from RAM and reloaded back when the program becomes active again. In a modern OS, with a fast SSD, this happens with virtually no slowdown. Not to mention that APFS is coming, which is designed to have very low latencies. So you can have as many applications open as you want without encountering any major slowdowns. Having loads of RAM has barely any effect here, because the times needed to reload app data from disk are not only super fast but can also be masked by transition effects etc.
Instead, if you actually want to use all the 32GB RAM, e.g. actively run all those applications at the same time — your limiting factor will be the CPU and its cache. If you have a lot of processes accessing a lot or RAM all over the place, there will be constant cache misses and your performance will suffer. As I said before, in order to utilise 32GB or more of DDR RAM, one really needs a quad core+ CPU with quad-chanel memory controllers and a lot of cache — and also tasks that can make good use of all of that infrastructure. An alternative of course is changing the RAM technology, e.g. use stacked RAM with lower latency and higher bandwidth.
Does that mean the analysts predicting 32GB RAM are banking on Intel being able to release a CPU capable of supporting LPDDR4 in time for the next refresh? (that timeline seems crazy tight unless Apple is planning on the current MBP having a long run, doesn't it?)
There's quite a bit of work people do using virtual machines that I know of, and editing/creating music and 5K and 8K video are all really ram-intensive projects.Just curious, what are people doing that requires more than 16gb of RAM? I've worked with some pretty intense projects up to about 25-30mins long in FCPX and I don't even think I was using half my RAM yet. What lines of work require that much system RAM?
