The MacBook Pro with Vega 20 ups the ante of performance and price


The i9 MacBook Pro is a feat of engineering and design that Apple has carried forward for the last three models, but choices made at the inception of the line are echoing forward to today, cutting back a very little bit on what the computer could be.

The latest MacBook Pro retains the fourth major body redesign that the product line has seen. The new design leans heavily on fabrication techniques used for the Retina MacBook, MacBook Air, and iPad, with the design still 0.61 inches (15.5 mm) thick —making it thinner than the MacBook Air.

Apple’s high end 15-inch MacBook Pro is still available in standard Silver and a darker Space Gray finish.

As before, the Touch ID button is still a physical one, and it serves as an emergency way to force a shut down in the case of a nasty Kernel Panic, as well as for authentication after you’ve logged in. Other power functions are handled automatically by default, with the user opening and closing the lid to respectively wake or sleep the machine.

The Touch Bar remains polarizing, is unchanged from previous models, and we aren’t going to discuss it here.

By the numbers

The whole point of the 2017 MacBook Pro refresh was the addition of Kaby Lake. The 2018 has taken that a bit farther with Coffee Lake, and DDR4 RAM in the 15-inch model. The November shipment of Vega 16 and 20 models takes that a bit further — for a bit more money.

For this review, we’re examining the 2.9GHz 15-inch MacBook Pro with i9 processor, 512GB of flash storage, and 32GB of RAM. The retail price on this configuration with the Vega 20 is $3849.

Keyboard, again and still

That keyboard. Once again, we’ve gone over this before, in our 13-inch MacBook Pro review, and the 15-inch i7 that was released at WWDC.

Keyboard key travel is minimal on the MacBook Pro.

It’s still got that rubber gasket. It’s still clackier than the 2015. It is still polarizing, depending on what you feel about key travel, and we still don’t know if reliability is any better than the 2016 or improved 2017.

But, on the subject of reliability —while Apple has a repair program for the 2016 and 2017 model, there aren’t an epidemic of failures spanning every user across the globe. We’re not thrilled that it is less reliable than the 2015 keyboard, but it is not a wide-spread phenomenon.

Even better GPU than before, but at a cost

The Radeon Pro 555 and Radeon Pro 560 shipped in the 2017 model. The 2018 model used to have “X” versions of both, with slightly better performance and more video RAM.

With the refresh in November, the 555X has been dumped in favor of the Radeon Pro 560X at a default, with user options for the Vega 16 and Vega 20 chipsets.

There’s been some confusion about the choice to use the Vega 20 name for one of the two options, as it is believed by enthusiast PC users that the Vega 20 will be the first GPU from the company using a 7-nanometer process. The desktop-class GPU is said to include between 16GB and 32GB of HBM2 and require between 150 Watts and 300 Watts to run, which can be generously described as undesirable for notebook usage.

So, this is not that.

In any event, the Vega 16 and Vega 20 include support for second-generation high bandwidth memory (HBM2) that provides a few extra bonuses compared to the more conventional GDDR5 memory used in other graphics cards. As the name suggests, it offers considerably more memory bandwidth per chip compared to GDDR5, while at the same time consuming less power —and it is on the GPU die, making for a simpler assembly to cool.

As it has done so for a decade plus, macOS can automatically activate and switch to the dedicated GPU when necessary and fall back to integrated graphics to save energy. In these cases, the on-board graphics are a hair faster than the previous generation’s integrated chipset, but nothing notable.

True Tone display

There’s a lot to say about True Tone. In short, Apple’s True Tone technology takes input from a pair of sensors in the screen, and will alter the settings of the internal display and compatible external ones to account for the lighting condition in the room.

This is unchanged from the previous model. We said that we’d tell you how we felt about it in a few months from a day-to-day use perspective, and the verdict is still out for us. We’re activating it for general use, and turning it off for applications that require precise color —which is perhaps what Apple intended in the first place.

RAM

Get as much RAM as you can afford at purchase. Like we’ve said before, it’s a worthwhile purchase if you’re looking to keep the machine for four years or more.

As with the summer update, Apple has shifted to DDR4 RAM to get the 32GB option, as it literally couldn’t get there with LPDDR3 RAM. The inclusion is both faster than LPDDR3, and more power-hungry. And, it’s also hotter, further complicating an already tight thermal situation.

Testing the silicon

Our model’s i9 CPU has base clock speed of 2.9GHz and a maximum boost clock of 4.8GHz. Geekbench 4 isn’t the entire tale, but results for this i9 Macbook Pro are an impressive improvement from the top spec 2017 model.

Starting with Geekbench 4’s OpenCL Graphics test, the Vega 20 achieves a 37 percent better score than the 560X. Geekbench 4’s Metal test showed a 23 percent improvement.

One thing we noticed was that the Vega 20 graphics in the MacBook Pro ran cooler compared to the 560X thanks to improvements in efficiency. Now this can lead to some more benefits, but we’ll talk about that more in a a bit.

Now onto some more serious benchmarks: video editing in Final Cut Pro X.

Starting with stabilizing a 20 second 4K clip in Final Cut Pro X, the MacBook Pro with Vega 20 only took 8 seconds compared to 13 on the 560X. Exporting a 5 minute 4K clip, Vega 20 took 3 minutes and 21 seconds compared to 3 minutes and 44 seconds on the 560X, which isn’t too big of a difference.

However, when we start using a more power-demanding format, like 4K RAW from the Canon C200, we see a much bigger difference. The Vega 20 exported a 5 minute 4K C200 RAW clip in 13 minutes and 54 seconds compared to 18 minutes and 30 seconds.

The real difference is in how well each MacBook plays back the footage while editing. Vega 20 was able to play back the 4K C200 Graded RAW footage at 31 frames per second compared to only 20 on the 560X. With the Vega 20, you get perfectly smooth playback, even if you shot your footage at 30 frames per second. That’s only a few FPS behind the Blackmagic RX 580 eGPU connected to the 15-inch MacBook Pro.

Thermals

The 15-inch i9 MacBook Pro is a hot machine. While it is pretty great, that’s not the hot we’re referring to. It runs warm in every regard, in a very small chassis.

But, there are some efficiencies in the Vega 20 that we didn’t see in the Radeon Pro 560X. During our testing, the CPU speed in the Vega 20 model exceeded the baseline speed under load by a higher margin than the 560X in the same 20C office that we ran the testing in the first place.

In our Red RAW export, which pushes the CPU and GPU to its limits, the i9 processor ran at a steady 2.9GHz compared to only 2.4GHz in our previous testing with the 560X graphics.

We also tested Cinebench R15’s CPU test to take the graphics completely out of the equation, and the i9 processor scored 57 points higher with Vega 20 graphics compared to 560X graphics, so Apple definitely improved something — but we’re just not sure what it is.

So as far as video editing goes, Vega 20 is more than a worthwhile upgrade for the extra performance you get.

Flash speeds are blistering

The drive is absolutely no slouch. Running the BlackMagic disk speed test after the machine had been indexing for three days, we saw a write speed of 2790 megabytes per second.

Other venues have claimed that this is because of APFS cloning, but after consultation with BlackMagic, we have confirmed that is not the case, and the speeds are genuine.

Thunderbolt 3

USB-C is not the end of the world, but it is an adjustment for users. That adjustment is better actually made, than struggled with using half-baked solutions. USB-C-to-whatever connectors are cheap, and plentiful. Complain all you like, but the Thunderbolt 3 with the USB-C connector is a universal port for video, power, and data, is far faster than USB 3.0, and is a game-changer for use cases, if you let it help you and fight it less.

Thunderbolt 3

A solution that may keep adapter costs down if you’re hell-bent on not recabling peripherals is a Thunderbolt dock. While Thunderbolt 3 docks start at $199 retail, the $49 Apple Thunderbolt 2 to Thunderbolt 3 adapter will work nicely if you want to use an older dock with the newer gear, possibly making the prospect of a Thunderbolt 2 (or even original Thunderbolt) dock cheaper than a bag full of adapters.

Furthermore, if you’re considering an external GPU, many of the enclosures have USB-A and Ethernet ports, in an accessory that costs not much more than a dock does. If all you need are a few USB-A ports, get a USB 3.0 dock, along with a USB-C to USB-B cable for around $8. Problem solved.

Better video, better computer, more money

If you liked the MacBook Pro’s power to price ratio, the Vega options add a decent performance package for the money. If you weren’t happy about the price as compared to Windows machines, this won’t help one bit.

MacBook Pro Vega 20

Editing video on the MacBook Pro with Vega 20 is a dream.

You can say all you want that there are cheaper Wintel vendors, and you’ll be right. Get the right tool for the right job. If Windows makes you happy, then by all means, head on over. But, the i9 MacBook Pro from the summer was right tool for macOS users, with the Vega 20 adding more for users.

But like the model it supplants, it still may not be for everybody, and that’s okay.
