not at all, i just find it highly unlikely given they're constrained by the same chassis.
Either the fan is bigger and pushes the same amount of air as two fans, or its faster (and louder) or it bends spacetime
Got a tip for us?

Can it not cool as well perhaps because they removed the vents on the new base model?

Sorry I didn't take a pic, but at the apple store today, both models side by side (the base models new version 2019 and the high end 2019s) clearly showed the two vents on each side underneath were removed from the new base model... even the apple guy was surprised..
[doublepost=1563061374][/doublepost]
Is it just me or would this make it get hotter? may the vents are not needed due to one fan? and exits at the rear beneath the screen? I just noticed how pleasant it was to pick up without the sharp edges! lol
The “vents” at the bottom of the high end model are supposedly for the speaker. They were never there on the base model.

hmmm, really? so the speakers then are not as good on the new base model perhaps? it just seemed very different.. and no one at apple had answer... lol... well they finally said it was for. the fans, and now that it has one fan it didn’t need two vents underneath.... hmmmm

Have no idea if the vents at the bottom are also needed for cooling.

[doublepost=1563065210][/doublepost]so assume the speakers are not as good then in the new base model 13?

Based on the tear down did by ifixit, the speakers of the new base MBP are directly underneath the speaker grilles. The speakers sound good in the review of Krystal Lora.

I'm curious what would be better for things like long exports, the 1.4-1.7ghz model with 1 fan or the 2.4-2.7ghz model with 2 fans.
Hey @NBAasDOGG, what are your impressions of battery life between the two models? I am super curious to see if the new 1.4 model has superior battery life to the 2018 or 2019 4tb port models. Any chance you can run a battery test?

yup just got my 256gb. Its 1300mb write and 1700mb read. Much better than the 128gb model. But read still half as fast as the 256gb 2.4ghz Pro

The four Thunderbolt 3 port model has, since 2016, had additional vents along the edges of the chassis. These do provide slightly better sound separation as the bass goes out the vents while the treble goes out of the upper grille, but the difference vs. the base model is subtle.
The main reason for the vents is the different cooling architecture.
The four Thunderbolt 3 model has two fans that draw in air from the side vents and exhaust it through the vents at the screen hinge.
The two Thunderbolt 3 mode has one fan, that draws air in on one one side of the screen hinge and exhausts it at the other side.
I say it is near in cooling capacity, not the same... But one fan has maximum about 7300 rpm, teo fans only about 6300 rpm...
These numbers are pretty poor but maybe better to put them in to perspective about how much they really matter in real life. I have personal experience with my own Windows desktop PC I built myself couple years ago. It is with 16GB ram and fast Intel 4 core CPU etc... but at the time when I made it I decided to use old sata2 ssd from my old system I was replacing it with. Then about year ago I finally upgraded that old sata2 ssd to NVMe/PCIe ssd drive. The new ssd drive has over 10x faster best transfer speed and even those smaller 4kb transfers are 2-3 times faster but guess what? If I did not install it myself and knew about the drive update I could not tell the difference in everyday use. Difference is so small in real use even speed test programs tell there is a huge 10x difference.
So if situation with MacBook is not much different, I think once you have ssd drive instead of spinning hard disk it does not make much difference after that about how fast the ssd drive is. Running operating system really has not benefit of maximum transfer speed as it does not involve large single file transfers but rather constant read and write of small files.
Sure if you need to move large files and you plan to use only internal drive for that, then you will benefit from faster (and bigger) drive.
Anyway, I still wonder if I will be all right with smaller 128GB ssd I chose my MacBook with. My Windows PC has 256GB but I have only about 72GB in use, so based on that I may be fine but I'm not sure if I want to use dual boot Windows with my MacBook eventually because then I may run out of hdd space.

you CANT go on just numbers, rather performance. Even if numbers given the configuration that doesn't seem bad at all honestly. I was trying one out in the store yesterday, and it seemed every bit as snappy as my 2.4!
Geekbench isn't really great for sustained loads. it takes what, 3 minutes?
Both chips are 8th gen, so if this were the case, using the 28W TDP (beefier) 2.3 chip would make absolutely zero sense in any context.
i mean, if that's the case i'm selling my 2.3ghz and buying a 1.4 and profiting 😀

which machine, feels faster to you? seems to perform faster, better? not just numbers?

Does anyone actually have the 1.4 now, if so what are your real world thoughts on how it runs etc? I am really thinking you wont be able to tell much different between this and the 2.4 in every day use, unless you do programming, photos, video, etc..... ?
Very interested to hear in those who have the new 1.4 now and impressions, and speaker sound too!
thanks

The same in day to say use as my 2018 base 13" Touch Bar. But I'm not doing anything demanding with it. The speakers are slightly worse but hardly noticeable.
Have you ever tested Air 2018 sound quality? I wonder if new entry Pro is about the same quality or worse than Air 2018? Based on iFixit teardown photos new Pro speakers look rather small, even smaller than ones used on Air 2018.
Also can you comment about display uniformity and backlight bleed? Is there much variation in color temperature if you compare different parts of the screen?

I had a 2018 Air for a bit. The speakers are about the same as those, which is still good. The screen is the same as every other MacBook Pro screen, mine looks fine, though I know a few have uniformity issues.
This is pretty good. My 2019 4TB is only marginally faster.
