Unless you need the portability, I'd buy the 16" every time.
Maybe for you. Looking at it from a financial perspective, 1,400 vs. 2,400 for a 512GB equipped MBP, a thousand dollars is not insignificant. Many people buy laptops for portability and the 13" MBP shines in the factor.

Plus you won't run into the ghosting issues, or the problems running an external monitor.

If by problems running an external monitors you mean fans spinning up do we know that? Especially since there are two versions of the MBP 13", 8th gen-single fan-2 USB C and 10th-gen-dual fans-4 USB C

And also assuming that there are no display issues...... We know how apple source from several vendors and we can't assume the panels are all the same.

Just got my i7/32GB/2TB yesterday and am already having major overheating issues. The fan is coming on every few mins and I am literally surfing the web and checking email. That’s it. I do no editing of any kind.

Already having regrets going for the i7 and if this persists the next few days, after what people are saying could just be indexing of adding my iPhoto library, this will be getting returned and replaced with the i5.

As already stated, it may need time to index. Still, keep us updated on this.

If you are using Chrome, try Safari. Especially if you are watching Youtube in 4K.

I'd actually prefer if he's using Chrome for him to keep using it and see if the problem persists after the indexing has finished. Chrome should not be making the fans come on like he's describing.

I'm specifically referencing the 16" MBP, the other member was stating that in nearly every case people ought to be choosing the 16" I disagreed

I wasnt talking about it from a financial perspective but I did make that point in a follow-on post In case anybody thought I was just assuming people could afford either.

the 13” Pro has been my go-to laptop for years and I’ve ordered one, but if I didn’t need something portable I’d definitely get a 16”.

I‘m not sure the same ghosting issues won’t exist with the 13” though, will be interesting to see how that goes for people as well as those external monitor issues - but our 16s seemed to be ok with the screens.

Just for perspective, Chrome on the 16" MacBook actually stresses the dGPU quite a bit more than Safari does. Even when no Youtube video is running, but especially when Youtube video is running.

This is likely an issue because Safari is running Metal and Chrome is stuck on outdated OpenGL. The Metal back-end for Chrome is not ready at all, and it's not even merged into Angle yet.

What I’d do is leave it on overnight. That should let it finish indexing. And just to be clear, did you migrate from a previous Mac or do a clean installation? If you migrated, there is a chance some errant app is running in the background. Try a safe boot (boot holding the shift key) if that’s the case. The i7 shouldn’t be “overheating.” My i5 had Windows 10 running in Parallels, Quicken for Windows running in Crossover (a WINE app), and Excel for Mac, and the fans never went on until I started installing Windows updates.

If you do decide to get the i5, what I’d do is order it now, and then wait until Day 14 after your i7 arrived to initiate the return. That will give you an additional 2 weeks to actually receive the i5 before you have to get the i7 back to Apple through 2-day FedEx (meaning you can use the i7 for up to 26 days and minimize the time you are without a MacBook Pro).

Ok, so fortunately, it seems like it was indeed the indexing. I only brought over about 50GB of data, but it looks like that was pushing the computer to run really hot and force the fans to come on. It definitely took longer than expected for that to complete, but i've been using it all day and although i feel the heat on the underside of the laptop, the fans have not engaged.

Thanks for the all the feedback guys.

Chrome will do it every time in macOS if you’re trying to watch a YouTube 4K video that’s encoded in VP9 (which afaik all of them are). Apple will not support it whatsoever so you’re using pure cpu to emulate what should be done on the gpu as all recent igpu/dgpu do. Windows 10 does it much smoother and with less heat as it’s supported in that OS

Indexing will make your computer run hot. The faster the SSD, the hotter it gets, and Apple uses pretty fast chips. Between that, the CPU and the GPU you’ve got a lot of heat being generated. It also makes a difference if you’re charging using one port and sending the A/V signal through the adjacent port (or anything else, really). That’s another 100W flowing INTO the machine!

Have been using 2020 13" MBP (1.4GHz i5 8GB) for about 8 days now. Have it connected via USB C to a LG UltraFine 4K monitor. The fan constnatly runs under light loads (Outlook/Safari/Word open). The surface below the down arrow key is VERY hot. Have reset SMC and confirmed its not indexing. Have used MacBook Pro's for about 10 years and never had an overheating issue. I connected my older 2017 13" MBP to same monitor and same version of OS X and zero issues. Simply posting to inform others there is possibly an issue. Calling Apple support later today see what they suggest.

Hi,
I am new to the MBP community and just bought an open box 16" i7 16gb memory MBP 2019 (later model) from Best Buy and I'm experiencing the thermal throttling/overheating when connecting it to an external monitor (basic Acer monitor nothing fancy). Does anyone know if Apple fixed this problem in the new 2020 Macbook Pro?

Thinking about returning this open box 16" MBP for the new 2020 13" with the magic keyboard and hopefully a cooler running system. I'm fine having the smaller screen, just want something reliable and easy to use for photo/video editing. Thoughts?

I would also save $200 since I paid $2K for this 16" and the new 13" is $1,800 with the i5 10th gen processor, 16gb ram and the 512 storage.

The 16" 2019 MBP and the 13" 2020 MBP have the same magic keyboard. As for Thermal throttling that was solved with the 15" model and there are plenty of articles to back that up with hard technical data. On that note all CPUs have a sustained and burst speed, once the CPU heats up it will drop from the burst speed to the around the core clock speed which can be sustained, Mac and PC are no different in this regard.
[automerge]1590578472[/automerge]
At about 10:45, Youtuber Max Tech opens up two 13" 2020 MBP models to see what the fan / heat sink configuration looks like. One is the base model with 8th gen intel processor, the other is the $1799 model with 10th gen processor.


If you buy the 2TB model the read/write speeds are 2700 MBs / 3200 MBs, far higher than anything in the review.

Not too surprising because it last year's 2019 13" MBP with a 8th Gen chip. Basically the same laptop with a new keyboard and ESC key. Are you seeing any lag or drag during during usage, if not then its spec'd correctly by Apple.

Try this! It worked for me. You can enable it now. See instructions in article.

Chrome will soon block resource-draining ads. Here’s how to turn it on now

That's true. I bought the 13" 10th GEN with 32GB RAM and 2TB for portability. The 32GB ram insures that everything runs smooth and the 2TB might seem pricy but it maxes out at 2700 MBs Read and 3200 MBs Write. If you need to run a lot of programs, with lots of browser tabs and some VMs this is the one to buy, unless you need multiple streams of 4k video, 3D rendering or high frame rate games. So far I've only paired this with a 2K 27" monitor but it runs like melted butter with 20 programs running. Again, it's not FCP, etc, but if you're pro who just needs to work across a lot of lower intensity media, this laptop kicks ass. What fan noise there is cold probably be killed with an eGPU if you need a lot of monitors.

Update: After MUCH troubleshooting Apple Engineering requested my MBP be sent to Apple to be further investigated. They overnighted me a brand new MBP. I now have the exact same issue where the FAN is on -85% of the time. I am using the MBP with only the Apple power cord (no LG 4K Fine display attached). The only way to use the computer without the fan turning on is have 1 or 2 OSX apps open at a time. Beyond Frustrating.

sounds odd. DO you know the temp of the CPU? have you looked at activity monitor?

Oh, oh. That is kind of scary. If that happens to mine it’s going back.

Awesome that blocking ads worked for you however, there is resource sapping bloat in Chrome itself which is why I use other Chromium-based browsers:

Opera (the first major browser to switch to a Chromium core engine back in 2013) and SRWare Iron (heavily user privacy focused and around since 2015).

I’ve been using a 2020 MBA i7 for over a month and a 2GHz i5 13” MBP for ~4 days now. Neither of which have had any thermal issues.

While there are a few unlucky ones who have legit and significant thermal issues out of the box, so many others appear to be experiencing data import, macOS indexing, application, browser plug-in or SMC related problems.

Update 2: Been testing multiple scenarios with 10.15.5 installed. I can re-create the overheating every time with the following scenario: MacBook connected to LG UltraFine 4K Display. Participate in a Microsoft Teams call with the organizer sharing their screen. Microsoft Outlook open, but minimized. The Microsoft Teams window is displayed on the LG UltraFine 4K display. The overheating (fan turns on, computer is very warm to the touch) begins within less than a minute after the call starts.
