All three 15-inch Mid 2018 MBP configurations benchmarked are at the top of Geekbench for multi-core, only behind iMac Pro and Mac Pro models [1]. Here they are in isolation compared to the 2017 and 2016 15-inch models sorted by score descending overall: | Model | Configuration | Score | |---------------------------------|------------------------------------------|-------| | MacBook Pro (15-inch Mid 2018) | Intel Cor…

Were the benchmarks run on a cooled room? Some years ago, as a student, I paid $$$ for a Toshiba with 4 cores and hyperthreading, and I could only run them well on the winter or in a very cool room. In the summer it would reach 100C and constantly throttle, so I do think that temperature is a key issue, sp. now with slimmmer laptops

Not sure on an individual basis but the Geekbench numbers are aggregate across all users of the machine.

I reached out to the video author to see if he'd be willing to run Geekbench on it in a freezer vs not.

Genuinely curious: I don't work in the space of CAD, video editing or any other field that people tend to use to justify the MacBook Pro's ludicrous pricetag that has some shiny numbers on the tech specs sheet. Do these really do anything a sufficiently equipped laptop from anyone else can't? Plenty of options with latest gen Intel and Nvidia 10xx series are out there for less insane prices. Granted, I don't see many…

I do some Photoshop and Lightroom work, but generally don't need an overly powerful laptop. I used to detest OS9 or whatever Apple had before OSX and stuck with Windows for some time. But after switching and when I last upgraded, price was no issue. There might've been a powerful, $500 Windows laptop, and I would ignore it. The MacBook Pro has simple, clean lines. It works well. The OS stays out of my way (I shrink and hide the Dock and don't use many of the other features - Expose, etc - can't even remember what they're called). I can't trust that to be the same for Windows-based laptops or other hardware.

If it costs $3-5k and I use it for hours and hours each day, years on end, it's peanuts as a professional tool. I'd rather pay and enjoy using it than take a discount but be frustrated each day.

OSX, as sibling pointed out, but let me be much more specific: - iMessage - excellent integration between Contacts, Maps, iMessage, Mail, and Spotlight - Mail.app, the best desktop mail client (IMO) - Siri > Cortana > Whatever tarball you are expected to run autoconf inside of to get your linux box to act like a mac from the 90s - excellent HiDPI support (neither Windows nor Linux have figured this out yet) - plug an…

Genuinely can someone explain why this is downvoted? The answer says “the software” which people constantly discount - just look at the cycle predicting Nintendo’s death every few years.

Anybody knows if Apple's ARM chips (iPhone) have better thermal efficiency (watts/GFLOPs) than the chips in this latest gen? If this is the case, I think it's just a matter of time for Apple replacing Intel with their own custom ARM chips.

You can't really compare ARM and x86_64 chips. I'm going to use a crude example. Think of the ARM chip being one of those USPS Trucks (https://upload.wikimedia.org/wikipedia/commons/3/37/Small_US...) while the x86_64 is a F150 pickup.

Both can drive around and transport things, but the USPS Truck is purpose build to deliver mail, stop and start frequently, and be reliable. It does a few things well. On the other hand the F150 is widely produced, can be customized in many different ways, and is general purpose vehical. Could it do the function of the USPS Truck? Sure, but it would be slower, cost more to run, and be less efficient. Could the USPS Truck haul a trailer? Maybe, but it wouldn't be very good at it. Both are a truck, but both are designed to different things and excel at different things.

That crude comparison is ARM vs x86_64. ARM is getting there, and for the specific ARM functions it's more performant than the equivalent x86_64 functions. But once you go outside of what the ARM chip has been specifically designed for, your performance takes a massive hit. Will ARM be able to take off in a Macbook? Maybe in a few years, but Apple would need to dump a massive amount of R&D into their designs before I would think they would consider it (but who knows?)

Comsol and sometime CAD user here, on a 2015 MacBook Pro, the latest of many Apple laptops for me.

My workflow runs faster on many laptops outside the walled garden. But I've gotten used to an exceptional build quality that's reliable under hard use, and OSX lets me think & work more like I want than other OSes. Also, my customer experience with Apple has been outstanding for decades.

For me, Apple has a mix of quality and aesthetics that I like better than what I've experienced from other manufacturers. It's been worth the price premium for me.

That said, I'm avoiding the butterfly keyboards until they really get them figured out.

I think the main quibble is that the laptop can't even hold it's base clock speed without throttling.

Yeah but that's like buying a race car and being upset that it's throttled at 300 mph. 99.9999% of people will never go 300mph..unless you're using it in a very specialized way.

If you spending 400$ to upgrade from an i7 to an i9, you are expecting i9 performance. If the i9 throttles, you are not getting that performance.

Here's a review from a dev who works at NASA:

Maybe the key point is he isn't running Adobe Premiere.

The thermal issues in modern laptops certainly concern me, but they've been running hot for a long time now, and being thin doesn't actually change the surface area significantly.

Yep Its just a million little details that make it such quality. The awesome UI of the OS. The trackpad is the best trackpad I've ever used. Every other trackpad feels clumsy after using one. The fact that it's a TRUE linux machine not just retrofitted Windows linux. The fact that everything just works. The chance of getting a virus is incredibly small. The time saved in troubleshooting is worth the price. Operating…

The fact that it's a TRUE linux machine

To be pedantic, a GNU/Darwin/Mach/BSD machine.

Yeah but I don't think buying a race car and use it to race should be considered as "using it in a very specialized way".

But does the i9 version have performance issues (i.e. it under performs compared to the i7)? The XPS 15 with the i9 configuration comes with 32GB ram and it much cheaper than an equivalent macbook pro. I can deal with it getting hot!

The XPS 15 i9 does do a bit of throttling, but off the boost clock (it manages to mostly stick to 4GHz in the stress test that Lee shows) while the MBP i9 apparently can't even maintain the 2.9GHz base clock. That, along with performance that's below the previous-gen i7 but charging $300 more is the real kicker - honestly, I'm not sure how anyone at Apple would be able to justify that as not just bilking their custom…

IMO the last good laptops Apple made were the pre-Touch Bar Retina MBPs. I've used three different ones, two for work and one that I purchased myself, and they were all solid performers with excellent screens, excellent keyboards, excellent performance, adequate ports, and adequate portability. The new MacBook, with its terrible everything-aside-from-thickness-and-weight, showed that Apple has lost interest in making a usable laptop in favor of any kind of differentiation they can get. Even if it's pointless or apparently even worse than nothing.
