Apple's Beats brand in April unveiled the Powerbeats Pro, a redesigned wire-free version of its popular fitness-oriented Powerbeats earbuds.
Thunderbolt 3 Ports on Right Side of 13-Inch MacBook Pro Have Reduced PCI Express Bandwidth
Apple has published a detailed support document highlighting the capabilities of the Thunderbolt 3 USB-C ports on the new MacBook Pro, unveiling some previously unknown details and outlining the different adapters that are needed to connect various accessories.
According to the document, while all of the ports on the 15-inch MacBook Pro and the 13-inch MacBook Pro without a Touch Bar offer full Thunderbolt 3 performance, only two of the four ports on the 13-inch MacBook Pro with a Touch Bar support Thunderbolt 3 at full performance.
The two ports on the right side of the machine have Thunderbolt 3 functionality but with reduced PCI Express bandwidth. For that reason, Apple recommends plugging higher-performance devices into the left-hand ports on that machine.
Other interesting tidbits in the document include the fact that six devices can be daisy-chained to each Thunderbolt 3 port on the MacBook Pro, and only one power supply can be used to charge the machine. You can attach multiple power supplies, but it's only going to draw power from the one that provides the most power.
Power supplies that exceed 100W have the potential to damage the Macbook Pro, and accessories like the USB-C VGA Multiport Adapter or the USB-C Digital AV Multiport Adapter can only provide up to 60W of power, which will offer slow or delayed charging in the 15-inch MacBook Pro. Apple recommends charging the 15-inch model with the power supply it ships with.
Apple also outlines powering attached devices with Thunderbolt 3 ports. The 15-inch MacBook Pro and the 13-inch MacBook Pro with Touch Bar can power two devices that use up to 15 watts and two additional devices that use up to 7.5 watts. The 13-inch MacBook Pro with no Touch Bar and two Thunderbolt 3 ports can power one device that uses up to 15 watts and one device that uses up to 7.5 watts.
If you're planning to purchase a new MacBook Pro and are confused about which adapters you're going to need so it will work with your existing equipment and accessories, Apple's support document is a good reference to check out.

Late-2016 MacBook Pro models vary slightly in the data speeds they provide to each Thunderbolt 3 port.As for USB, all of the USB-C ports on all MacBook Pro models offer USB 3.1 Gen 2 (10Gb/s) transfer speeds when connected to a USB accessory.
MacBook Pro (15-inch, Late 2016) delivers full Thunderbolt 3 performance on all four ports.
MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports) supports Thunderbolt 3 at full performance using the two left-hand ports. The two right-hand ports deliver Thunderbolt 3 functionality, but have reduced PCI Express bandwidth.
MacBook Pro (13-inch, Late 2016, Two Thunderbolt 3 Ports) delivers full Thunderbolt 3 performance on both ports.

Wow this is very unlike Apple. I remember when they came out with USB 3 they boasted how they didn't have to label them blue because all ports had the same speed!
Just one more inclination this is Cooks Apple and not Jobs' Apple

Apple is becoming a company I barely recognize. What happened to their practice of delighting us with "magical" technology. It's now getting to a point where I'm thinking, "I wonder in how many ways this new product is going to disappoint me?"

How many actually need that bandwidth on even ONE port much less 3 to 4? And are actually in the market for the 13" Pro right now? How many were truly planning to get the 13" and hook up 4 TB3 devices that need that bandwidth? How many pay zero attention to far more significant positives, from screen quality to giant trackpad?

Why are you convinced this is related to saving money instead of saving space and efficiency?
Because for $2300, I'll be expecting a computer that is capable to distribute bandwidth equally to all four ports.

Wow. This ****ing company has gone THIS far huh.
I thought that the final save point for this MacBook Pro was that at least it's a powerful computer. But clearly, Apple went as far as to reduce the speed of certain ports to save some pennies. Unacceptable, Apple. A pro machine my ass.

Apple really screwed people who wanted the 13in.
They've screwed everyone this year;
iPhone users don't get a headphone jack.
Apple TV comes with a USB port but you can't connect sh*t to it.
MacBook users get crippled MacBooks.
iMac users get nothing.
Professionals get less than nothing.
