New Mac configurator may point to separate CPU and GPU options

Apple last week changed the way you buy a Mac online, removing the previous lineup of customizable pre-configured options and instead putting you straight into configuring your spec from scratch.

While at first glance this seems a somewhat strange thing to do, arguably making it a little more complicated for a non-tech buyer to choose their Mac, the change could provide support for a theory that Apple will allow you to separate CPU and GPU options when buying an M5 Pro or Max Mac …

The new Mac configurator

You’ve always been able to configure the spec of your Mac from a wide range of options. However, prior to last week, Apple would begin the purchase flow by offering you a number of standard configurations.

Previously when you clicked the “Buy” button, Apple’s Online Store would first take you to a landing page. On this landing page, you’d see a range of prebuilt options with various chip, RAM, and storage options. You’d choose the starting configuration by clicking “Select” and could then fine-tune your machine to your exact preference or proceed with the default configuration.

I strongly suspect that for the MacBook Air at least, the majority of people simply chose one of the pre-configured options and didn’t make any adjustments to the spec.

Now, however, you have to make every decision yourself, starting with the screen size and proceeding down to the pre-installed software. That would seem a retrograde step in Apple’s approach to simplicity.

This may be the reason why

While you can choose the processor for your machine, you are stuck with Apple’s fixed combinations of CPU and GPU cores. That’s because the two of them are tightly integrated  in an approach known as a System-on-a-Chip (SoC). Essentially what would have been completely separate chips are integrated into a single, tightly-integrated unit containing circuitry for both.

For the upcoming M5 Pro and Max chips, however, Apple is reportedly switching to a new chip packaging process that allows greater flexibility.

Apple analyst Ming-Chi Kuo says that for the M5 Pro chip, Apple will be taking advantage of TSMC’s very latest chip packaging process known as SoIC-mH (System-on-Integrated-Chips-Molding-Horizontal) […] to improve production yields and thermal performance, featuring separate CPU and GPU designs.

One of the implications of separating the CPU and GPU within the packaging in this way is that it would allow Apple to give you the option of configuring the two individually.

This might make sense, for example, if you were doing graphics-intensive work that doesn’t make too many demands on the CPU but requires as many GPU cores as you can get your hands on. In that case, you might want to opt for the base CPU and a maxed out GPU.

It should be noted that there is no guarantee Apple will choose to offer this flexibility, but it strikes me that the change to the configurator perhaps points in this direction. We may not have long to wait before we find out, with the M5 Pro and Max variants of the MacBook Pro potentially launching this month.
