There has been talk for some time about how Apple devices running iOS are contenders for replacing standard Intel architecture computers, such as MacBook Pros. Since I have a number of Apple devices, I thought I’d install Geekbench 4 (version 4.1) and run it across three of my Apple devices. I’ve put the results in a simple table below, with the results in the first three rows.
|MBP mid-2015||iPhone 7 Plus||iPad Pro 2016|
|Processor||Intel Core i7||Apple A10 Fusion||Apple A9x|
|Max Frequency||2.8 GHz||2.34 GHz||2.26 GHz|
|OS||macOS 10.12.5||iOS 10.3.2||iOS 10.3.2|
The MBP I own is a 15″ Retina MBP with 16GB of memory and the 2.8GHz quad-core i7. I wasn’t surprised to see the MBP be the leader across the board, particularly in multi-core scoring. The MBP is certainly the brawniest of the three with its Intel processor and eight times the memory over both the iPhone and iPad. Keep in mind that the MBP is the oldest of the three devices.
What I found rather interesting is the GPU-based Compute score. The iOS version of Geekbench uses Metal, the graphical framework that’s a part of iOS. Geekbench on the MBP uses OpenCL and because I’m too cheap to buy a copy, the built-in Iris Pro on the i7 processor was used instead of the beefier AMD Radeon R9 M370X. So even though I’m using the “lesser” graphics processor and “poorer” graphics software framework, the MBP still scored a solid two to three times faster than either iOS device. Of further note is the sizable performance lead of the iPad over the iPhone, even though the iPhone’s CPU is clocked faster and it’s using a more current Apple SoC.
So, am I ready to trade in the MBP for either iOS device? It all depends on the use case.
For general uses involving reading content and typing, I could easily switch to the iPad Pro. I use it with a Logitech keyboard-and-cover in landscape mode, which, when attached to the iPad using the Smart Connector gives me a decent keyboard with back-lit keys. It’s not as efficient and comfortable as the MBP keyboard, but it’s more than serviceable especially over a period of hours. I can do writing and other types of textual creation, as well as fairly sophisticated graphical content creation and photo/video post processing. There are, however, limits to the iPad Pro.
For the ultimate web experience I prefer the MBP and my selection of browsers, which includes Chrome, Firefox, and Vivaldi. I am not a fan of Safari on either iOS or macOS, and I don’t think I ever will be. What makes web browsing on iOS truly annoying is Apple’s insistence of forcing every other browser to use the Apple web engine used by iOS Safari; it is buggy and poorly performant.
When I need to develop software I much prefer the MBP. When I need to do light code editing on the iPad Pro I use Textastic with Working Copy. I have iOS Terminus that allows me to ssh into machines around my home running Linux and macOS (nothing like that for Windows, unfortunately). Under ssh I tend to use vim with extensive vim customizations and colorizations. And I can use scp and git to move things around that need moving. So the iPad Pro makes a pretty decent work platform when I don’t want to fire up the MBP, especially when I need to put it down due to interruptions.
I haven’t even mentioned the iPhone, but it’s decent enough that it can fill in for the iPad when all I can carry with me is just the iPhone. I use a Microsoft Folding Bluetooth keyboard to type on, and I have an SDHC to Lightening card reader for reading JPEG and RAW files produced by my Olympus cameras. The same apps I would use on my iPad to post process work just fine on the iPhone 7 Plus. And when I don’t want to, or can’t have, my Olympus camera, then the iPhone 7 Plus camera is just fine.
And the 15″ screen on the MBP is the easiest of all the screens to read, which is important due to my poor eyesight (20/700 and near sighted).
There is no easy answer to the original question, except to say it all depends. As long as I can choose which to use for which task, I will choose all three based on the work at hand that needs to be done.
But I am impressed with what the Apple SoCs can accomplish. While the MBP rules them all, for single core scoring all three devices are fairly close together, compared to multi-core and compute. This bodes well for Apple’s continued evolution of its ARM-based processors, and if I were Intel, I really would be looking over my shoulder at ARM in general and Apple in particular.
