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
CPU Single-Core 4462 3457 3017
CPU Multi-Core 16005 5872 5082
Compute 38117 12296 14764
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.

Finally, there’s the truly heavy lifting that the MBP is called upon to do. For example, I have a number of Linux virtual machines I power up to perform testing and development in parallel with work on the MBP. I use Xcode to develop iOS applications, as well as Android Studio to develop Android applications. If I want to develop using a full Javascript stack starting with node.js, then the MBP is the only way to go. If I want to develop in Java or Python or Go or Rust, only the MBP allows me to do that.

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.

The Samsung R580 is like the Timex watches of yore, when they “took a lickin’ and kept on ticken’.” Or maybe it should be compared to something more contemporary like the Energizer Bunny. Regardless, the R580 continues to do yeoman duty, what with its ‘mere’ 4GB of memory and now-modest Intel Core i5 m430 processor. It was originally purchased with Windows Vista installed back in 2010. It was upgraded to Windows 7 when that was offered as a free upgrade, and stayed that way until Windows 7 decided to corrupt itself. When that happened I installed Ubuntu 13.10 on it in December 2013. It’s been an Ubuntu workhorse ever since.

When I upgraded the R580 to Ubuntu I replaced the keyboard and put a new 500GB hard drive in it to match the size of the original hard drive. Over the years I started to replace the hard drive, first with a 1TB model, then a second just to make sure that at least the rotating media was kept up to date. I thought about upgrading to 8GB, the highest you could go with this model, but I just never got around to it. This December, I decided to be a bit more drastic with my upgrade.

As you’ll note above, I upgraded the R580 with a 1TB Samsung 850 EVO SSD. The price finally dropped low enough to make installation a no-brainer. I’d already upgraded a Samsung 17″ running Windows 10 with a 1TB Samsung 950 Pro, and I’d purchased a mid-2015 MBP with a 1TB SSD built in. So I was quite appreciative of how an SSD significantly speeds up a computer. It just made more sense to spend the money on the SSD rather than more memory, so when the Christmas sale on the 850 EVO was announced I picked up a copy, along with a Sabrent USB adapter. With Clonezilla on a USB thumb drive, I booted into Clonezilla and proceeded to clone the HDD disk to the SSD. Total time took about two hours, most of which was just waiting for it to finish. Once finished I swapped the HDD out for the SSD, booted the system back up, and here I am writing this blog entry on it.

Before you ask: No, dd is not as good as Clonezilla, at least not for this use case. For example, Clonezilla (for which I have extensive experience) will analyze the drive to be cloned and only copy over what needs to be copied over. dd is blind in that it duplicates the entire drive from one device to another. And in order to make that work you still need to boot into a live version of the OS from a thumb drive, so the amount of prep work is identical. It makes far more sense to use Clonezilla.

Needless to say, everything is so much faster, from startup and shutdown to launching applications. And if it goes to swap, well then, it goes to very, very fast swap. I don’t intend to do any more hard disk upgrades, just as I don’t intend to update the OS beyond Ubuntu 16.04 LTS. I’ll keep using the R580 until it literally dies of something, I’m not sure what. I keep thinking I’ll replace it with another used notebook, but its overall combination of reasonable performance, many ports, and the fact it has a Blueray drive make it hard to find a replacement for, now that everybody and their relative wants to drop ports and repairability and upgradability in the name of convenience, cost cutting, and dare I say it? Lock-in.

Here’s to another five years of drama-free usage.
