Why is everyone going 16GB? 8GB not enought? With the pcie-HD, Mavericks etc do you really need 16?

Will do some matlab etc, but nothing too heavy...

Why upgrade to 16 GB of RAM? Because you can't upgrade the RAM in the future on the rMBPs. I've never regretted having too much RAM. I've always regretted not having enough.

That said, for most people out there, Mavericks with 8GB of RAM will probably keep them very happy for the life of the machine. Web browsing, iPhoto, iWork, home videos in iMovie... None of those things will push RAM usage.

Anyone who is running VMs, RAW photo editing, Video editing, etc. probably wants to max the RAM to future-proof their system as much as possible.
 
I'll use it:

You just linked a screenshot with over 1GB of completely unused RAM and another 2GB of inactive RAM. In addition to better memory management in Mavericks, you just made a case for why you yourself do NOT need 16GB...
 
for Uni work, internet etc all the usual! Is RAM or CPU more important?? Coming from a 15" rMBP that was stupidly way to much for my needs!!

Why would you change it then? I need more context, but it looks like you should either stay with what you have or wait for rMBA and sell your mac then.
 
If you want to run many programs at the same time -> RAM

If you want to do some rocket science calculations -> CPU

Well as I do forensic science I guess RAM is the answer!! I use very basic molecular drawing software that was no problem on my 15" so hopefully should be okay on the 13" i5
 
Changed my mind - gone with 8gb

Ok I changed my mind.

I bought the i5/8GB/128

Thank PDFierro for your suggestion!
 
No. Battery quotes have always been based on the iGPU. In this case, we're talking about the same GPU in both models. The dGPU is actually irrelevant. Therefore, you should assume 8 hours in both cases. And since real world usage usually is a bit behind marketing claims, that means probably less than an hour of improvement over the previous generation.
Ah cool. Thanks john123. Surprising that there isn't a bigger battery gain. Guess it did go toward clocking.

I've already sold the rMBP! Did do in June. I had an unfortunate drop and so wanted to get sold ASAP and therefore got a lower price than what I would have

You will be fine. I only notice the difference between i7 and i5 when running something like 16 parallel code tests on my machine.

Maybe not today, but what in a couple years? 2017? 2018? I don't know about him, but that's the reason I went for 16.

8 GB is the minimum today. I would say 4 GB was the minimum, back in 2009. 4 GB is laughing at the consumer while walking all the way to the bank.
 
I didn't really read today's posts, but I for one am fine with this upgrade. I just ordered the 13" with 16GB of RAM and it should get here by Halloween. I can always sell whenever Broadwell comes out if it ends up being tons better. :cool:

Agreed. I think upgrading to the i7 processor is way more worth it than 16GB RAM.
 
Battery life for the 15" version is disappointing, especially given that this upgrade has both Haswell and Mavericks. It seems like it's XPS for me.

It also seems like both Dell and Apple are trolling me. Dell has not yet released the XPS 15 in my country, and shipments seem to be slow even in countries were you can buy it. Meanwhile Apple's prices are unchanged in my country. The iGPU-only version costs as much as the old base 650m, and the 750m is even more expensive!

Thanks very much!! Like I say it's very minimal work and as I never had any problems with my 15 trying to find out what 13 would suffice!

You obviously missed the 8GB of page outs and swap used which indicates at some point since my last reboot (earlier today) I had no available memory.

I still feel that a 256GB SSD should be the minimum for anybody on a machine like this. But to each their own.

Enjoy it! And you will be glad you got 8GB RAM.
 
That isn't what you said, though. You said, "I'm confident that there's a big amount of people that'd rather not have a dgpu." Ignoring cost, there's no logical reason anyone wouldn't want the dGPU

That's not what I said either. What I said was
I'm confident that there's a big amount of people that'd rather not have a dgpu, but still have a better cpu.

Given the fact that the Iris Pro is hardly a slow piece of hardware, and, as you probably know, can match or even exceed the nvidia chip in some areas, I see no reason why the option of not having one for the higher-end cpu isn't there.
 
Iris Pro has more ALU (= programmable unit performance) at a higher clock speed than the 750m. It also has much(!) more low-latency, high-bandwidth cache available than the 750m. The 750m, on the other hand, has much more TUs (texturing units) and ROPs (Pixel backends), as well as a high bandwidth for its entire 2GB of VRAM (Iris Pro only on the amount of data that fits into the L4 cache of 128MB).

In theory, the Iris Po should be much better at GPGPU (OpenCL), while the 750m should be, on average, better at rendering. That is what all the benchmarks have shown so far. It is also generally known that nVidias Kepler architecture (at least in the variant used in the 650m/750m) is relatively weak at GPGPU (OpenCL/CUDA).

Thank you for the education, noble sir!
