Friends... Trying to play the longevity game here if I pull the trigger on this.

Looking to for sure get the 32gb ram. But now staring at the i9 and wondering if 5-7 years from now it will keep me in the game and provide me a fast laptop.

I do quote a bit of video work, web design, some graphic work, and run a VM for some IT support work.

Of course it's too early to get many tests... But always welcome your opinions here.

Thanks!
 
if the i9 will heat your internals more..than from longevity stand point, get i7...but we must see
From my research the i9 will heat up the 15" at 44C instead of 41C the 15" 2017 i7
 
One YouTube review showed a Cinebench R15 score of 974CB for the i9 which is not great, similar to the XPS 15 the deminuative chassis and lack of cooling takes it's toll on CPU performancel, if this is the trend.

Personally I would wait until the results are in for the other CPU's. My own primary W10 notebook scores 1273CB with the 8759H, i9 I would be expecting around 1400CB. In the case of the 2018 MBP the performance differential may not be so broad given the constraints of the chassis.

my rmbp late 2013 is all speedy and fast and it even beats more recent ones the thing is that Apple stops supporting machine after 5 years. So you will run a deprecated OS (which may run deprecated apps) and have a hard time replacing the battery (unless you change it at the end of the 5 year period). Beside that, my machine is flawless.

People critic the price of macbook but it's all premium components. I configured a Lenovo t480 (it came around 3000$CDN: 4k display,mx150,32gb ram) and it had a 256GB sata SSD (~520MB speed). My 2013 rmbp have ~800MB/s speed and the new ones are around ~3000MB/s.

In 5 years, the machine will still have a faster SSD than 95% laptop out there, have more memory (I don't foresee 32gb being the standard).

Yes, there will be faster mac, but it's ok. Here is a review of the i9 / 32gb by an independant reviewer.
 
Many here are excited about the hugh performance gain in the i9 in MBP 2018. How is it compared with the 8700K?
 
The CPU you choose will likely be of little help when it comes to support from Apple.

Apple more frequently discontinues support for a product line based on the GPU used in that product line (though occasionally it has been CPU).

So from that perspective, I wouldn’t buy more than you need in CPU terms unless you are looking at just wanting to have the best performance you can get.

Most likely, 3rd party software is going to support your computer longer than Apple will with Mac OS updates.
 
I vote for the i9. Put the thing on a cooling pad and you'll be fine for heavy use when you don't need to be mobile. The i9 has a larger L2 cache. You'll be glad you had that extra clock when rendering.

I have yet to find a good stand or laptop cooler. Tried anything good that really drops the temps down?

No cooler will make any significant difference, even with notebook's with air intakes on the bottom. Mac's less so due to the orientation of the air intakes.

Elevating the rear or placing the MBP on a passive cooler stand is as good as anything else out there.

I'm with you I think this is a good upgrade. I tell all my clients dont upgrade if it's a .25 of a CPU clock bump. But i7 to i9? I have to do it.

Other than the increase in heat it is a solid upgrade. The L2 cache increase is noteworthy as well as the turbo boost performance. It'll be faster than most desktops.

edit: something something throttling

I sometimes use laptop on my laps so if i9 generate crazy heat or sounds like a vacuum cleaner or jet engine, I would not choose it.
[doublepost=1531793255][/doublepost]How the MBP with i9 sounds like when doing productive work and when it is under heavy load.
 
You guys think it will be that much hotter?

I'll sometimes whip up simple videos while using a computer on my lap.

Mostly for bigger projects I'm at my desk using a laptop stand.
 
Doesn't sound like many will have the answer... guess we'll have to wait for a comparison video to be sure.

I chose the i9. My 2018 15" 1TB SSD with 32GB RAM and i9 will arrive on Monday, so I'll be sure to explain my experiences for FCPX use.

What sort of questions are these? Seriously you guys ask these questions as if you've never used a computer before.

You know damn well that a 6 core i7 will still hold up fine 5 to 7 years from now.

People are still using processors from 2012 to get **** done.

My 8700K does ~1700 in CineBench, while the i9 does..... 1000-1200? I guess it depends on whether you're asking about the i9 in the MBP or the true full potential of the i9. You can probably view the i9 as a mobile version of the 8700K.

I'd suggest going with the base model i7. It's going to be plenty good for the lifetime of the laptop. Either that or wait for more data on the i9 I guess. But I suspect more data is just going to confirm what we already know. It adds cost and heat, but not performance.

Here is another video with different results.


Also reviews that give us more insight into the i9:

http://austinmann.com/trek/macbook-pro-2018-review

http://hrtapps.com/blogs/20180712/

Moral is never come to conclusions based on a single (or two) youtube videos. Let’s wait for more real world tests.

Are you going to go into every single thread and paste that video in order to defend apple and your decision to buy the i9????

Does it make you sleep better at night (baa baa)?

There is a thermal problem. period.

I am thinking of buying a new MacBook Pro 15, coming from a 15“ 2015 mid. Most of the time i am working with big excel files simultaneously, also doing a lot of photoshop.

Would I feel a difference between the i7 and the i9 in daily usage? I assume with my tasks It would never need the boost of the i9. So would it then never heat up and run smooth with 2.9 ghz base frequency? Or would the i7 be enough for my needs and I should save the money?

I am so confused with this throttling discussion going on...
