Waiting for the 32 GB MBP

[The Mercurian]

Did that and saw a screen dump of a system that was gorging on Ram despite not seeming to be doing photo, video, audio or coding type work.

I don't get the relevance though.

Clearly. Rsession is a statistical modelling program. You really don't seem to realise there is work other "photo, video, audio or coding type work" that is demanding. In this case, that was an accident - but I do sometimes need to make statistical models > 16GB - and I don't even do particularly demanding work compared to some.

32 gb ram most likely won't come until 2019. Enjoy the wait

Thats no shock to me. I don't expect them to change it for at least that time given who long the last update took. No waiting for me though, I'll be switching to a Dell XPS next year when it gets the KabyLake update.

By the time they make a 32gb macbook, pc laptops will commonly have 64 and 128gb. To use a macbook is to accept having 1/4th the ram of powerful pc laptops. I'm waiting for apple to make a macbook-pro-pro or for one of these powerful laptops to not have all the wacky gaming colors you wouldn't want to take anywhere serious.

In my experience one of the main reason for requiring greater than 16GB RAM on a laptop would be to run either VMs or multiple server applications. The sales engineers in my company often use 32GB Dell workstation laptop for customer demos, generally running Linux. Most of the software packages combine multiple large Java virtual machines of 4-8GB heap size and large Oracle databases. These run very poorly if they are swapped out to disk, even fast SSDs. I have often brought my 16GB rMBP 15 to its knees running VMs, but very rarely with other applications.

Don't look at "free RAM" in the Mac OS activity monitor - the OS will use available RAM as a cache to improve performance , so free RAM is often very low by design - unused RAM is wasted RAM!

Instead look at the "memory pressure" color, and more specifically the "Swap Used" figure. If this is more than about 1GB, and you need to use multiple open applications with frequent context switches (i.e. switch between apps frequently), then you will notice significant slow downs while the computer swaps application memory from SSD to RAM. If you don't "jump around" your open apps, then you can probably tolerate a higher usage of swap space.

Mac OS will always use some swap space by design, but aim to keep this low (< 200-500MB) for optimal performance if you do a lot of application switching.

I was hoping to finally upgrade my early 2011 MacBook Pro this year, but just can't justify it. The only hardware limitation I have performance wise on my current almost six years old MBP is the RAM. In 2011 I typically used around 4 GB of RAM, and now I'm usually around 12 GB of my systems 16 GB. 16 GB will probably be ok for another 1-1,5 years, but no way will I spend 2 800 USD on a new MBP that will run into the same limitation and at the same time as my six years old MBP. That's just ridiculous.

So until Apple introduces more powerful RAM options to their laptops for professionals I'll hold on to my early 2011 MBP, holding my thumbs for a 32 GB option in next year. But if Apple doesn't deliver within a year I might finally jump ship and go with a Windows laptop Because other manufacturers actually deliver 32 GB. For example this Dell in a slim form factor and 30% lighter than my current MBP: http://www.dell.com/us/business/p/p...1015us_4&model_id=precision-m5510-workstation

Wow, and i thought Apple laptops were expensive. Those Dell's with 16GB ram and 512GB SSD is over $7000!!
Makes the MBP at $4200 look like a bargain!

I never did do any statistical modelling on my maths degree just plenty of mathematical modelling! Given that your data sets are in the tens of gigabytes, I have to assume that you are interrogating using CODe are you not? Perhaps even something like SQL or a specialist derivative of.
I don't think anyone denies the fact that there are more than a thousand different uses for a powerful machine. I think for a user who is not power hungry, video, audio, image editing and coding are easier examples to understand than interplanetary gamma ray analysis or other similarly interesting tasks.

I'm waiting for the 64gb RAM. Solitaire will fly then! You guys are suckers.

Personally, I think just looking at the amount of memory being used will only lead to confusion and memory anxiety - macOS (like any modern operating system) will use as much memory as there is available because unused memory is wasted memory. However, just because something is using it, it doesn't mean it has to

I've just tried a very unscientific experiment, but it does illustrate the point:

I have an iMac with 32GB and a rMB with 8GB. I opened safari on both with the same tabs open. On my iMac, Safari is using 1.78GB and on my rMB, it's using 327mb.

Also, I've got pretty much the same programs open on both machines and my iMac is at 15.34GB of App memory and my rMB at 2.85GB with kernel_task on my iMac using twice the memory of my rMB and Window Server using 3 times

Basically, if your memory pressure graph is green then you don't have memory issues! The only time I get anywhere near needing the 32GB I've got in my iMac is when I spin up multiple VMs which is not something I do very often

I am just asking for what's reasonable.

built the same system on the US site, $3900 US ($2400 with current discounts). adding the Australian exchange rate and tax, that system would be around $6000 AU. damn. another $1000 for? at least that Dell can take 32GB of RAM.

I guess I could buy 2 base model 15"MBPs for the same price. Then I'd have 32GB of ram too! Haha

 

[azpekt]

although I`d like to have 32gb, I dont need 32gb

i have 2015 rmbp15, and do a lot of development using docker/kubernetes/virtualBox. and it works.

i can surely wait a few more years for 32gb
