I have 2015 and I open chrome with 10 tabs and each tab either has a data grid or a chart in it. This causes the chrome to freeze couple of times a day and when I see the activity monitor, it shows almost 14gb used up with App memory aorund 9 GB.

Wondering if a 2018 with 32 GB and higher Processor solves my problem.

Anyone in the same boat could give your input please?
Thanks

I would think your problem is with Chrome, not the computer. But yes, the 2018 models will be be better performers than the 2015 models.

Well I tried Safari, FF and even Opera and none of them did any good, sluggish like Chrome.
 
I am not sure which model you have but a stronger processor and extra RAM will definitely give you a much better experience than you're getting right now with the open tabs. I use Chrome with many tabs open at the same time (mostly videos) and it's fine.. so I don't think Chrome is the issue in your case either.
 
I currently have late 2011 15" MBP and ordered 2018 15" on Wednesday.
So I can't answer your question.

But I would suspect the processor power itself of 2018 will make it significantly faster and avoid hanging.

I know the data in the chrome tabs is the issue with data grids and charts.

I was hoping a new computer with higher ram and processor can alleviate the Pain.

I hate to buy a new computer to find out that my problem is still there. I hate returning stuff.

Look up Geekbench results for both, compare.

That was a great idea.

Per Geek bench

Multi-core
---
2018 - 21119, 2015 - 1293 (both starting processor)

single - core
---
2018 - 4913, 2015 - 3777 (both starting processor)

Seems like a good improvement if it uses multi-core while on Chorome?????

Any idea how these cores work on chrome?

Your question can’t be answered with certainty. And looking at geekbench or other benchmarks in your case is utterly pointless. The new Macs are faster - but it all depends on what you do. The websites you visit might be badly coded, in which case the performance is likely to be bad no matter how fast the machine.

Best course of action fir you would be to buy one, try it out, and use Apples return policy if you don’t like the result.
 
Or you could attempt to recreate your user experience at the Apple Store on one of their new models and see how it goes, I don't think they would mind.

Not sure but unless you are running 40+ tabs, I don't see the 2015 lacking enough to require an upgrade.
 
Went from mid 2014 13" i5/8GB/512GB to 2018 13" i5/16GB/512GB.

The improved CPU performance is noticeable but not really all that amazing to be honest, especially when you consider the 4 year difference between them. It's only when you do something really heavy that uses all cores to their max that you notice a huge difference. For everyday surfing and such, it feels just a tad snappier and more smooth.

Going from 8GB to 16GB is huge though once you start going crazy with tabs and apps. In addition to that, once you go past the 16GB limit and start hitting the page file, the 2018 model feels a lot more responsive than the mid 2014 model when it goes past the 8GB limit (the faster SSD perhaps?).

Everything else feels like an incremental upgrade. It's all nice and it adds up, but nothing about the 2018 model makes me go OMG - that is too cool! Must have! Kinda makes me regret that I didn't get my 2014 model with 16GB of RAM. It's the RAM and multicore performance that makes the biggest difference between the two IMHO, but I don't do much multicore stuff, so for me it's mostly the RAM. I would have just kept the old one then and returned the new one. Don't get me wrong, the 2018 13" is a solid machine with good performance when you consider the form factor. It really is a joy to use, it's just that you can get a lot of other cool stuff for the price of a 2018 13" i5/16GB/512GB and my mid 2014 is still a surprisingly fine machine as long as I remind myself to actually finish things and not have 20+ partially watched YouTube videos sitting in the background along with some 30+ other tabs. Yeah, I totally do that - lol.

Awesome write up and makes me wonder if my 2015/16GB is good enough as the app performance on the chrome might be same with 2018. i will have to try it in Apple store soon.
