Some 15-Inch MacBook Pro Models Misreporting Intel Iris Pro 580 Graphics

Several MacRumors readers have discovered that System Information readouts on some 15-inch MacBook Pro units appear to suggest they are running Iris Pro 580 integrated graphics, rather than Intel HD Graphics 530 as advertised in Apple's tech specs.

The strange inconsistency was first found on some demo units running in Apple Store showrooms, leading some readers to suggest Apple was running higher-specced machines in-store. However, since then, some owners of newly shipped 15-inch MacBook Pros have also noted the same inconsistency in stock laptops sold to them.


MacRumors forum member torquer discovered that on their machine, System Information reports an Intel HD Graphics 530 when the laptop is running on battery, but reports Iris Pro 580 once it's plugged in.

This would suggest a bug in macOS Sierra is causing System Information to misreport the integrated graphics chip in some 15-inch MacBook Pro models. Another indication of misreporting is that units which identify the GPU as an Iris Pro 580 appear to show the device ID string "191b", which correlates with the Intel HD Graphics 530 chip.

In addition, owners of machines reporting the more powerful Iris Pro 580 are not seeing the kind of graphics performance improvement one would expect. For the record, Intel only matches the more powerful Iris Pro 580 to Core i5-6350HQ and Core i7-6770/6870/6970HQ mobile processors, none of which Apple chose to use in its latest lineup of notebooks, likely due to power consumption concerns.

I feel like these MacBook Pros are Apple's Windows Vista.
Totally new product. I'm sure these things will be resolved via software fixes. If not, that's why there's a year warranty or the 3 years of AppleCare options. Or worst case, return policy. I just ordered one last night, so I'll be hoping for the best.

Depends on if they actually view it as a defect I guess. You know, they have such a great policy on admitting mistakes right now.

Seems like a non-issue. The machine still works right?

Tiny bug. Not worth a whole article really.

It was, so people can say things like "They did this on purpose" and "This is Apple's Vista" hysterically. This forum loves things like this more than anything else.

Wait for the Tim Cook should be fired dude.

I would totally agree with you on these points, if it wasn't for all the other things being reported.

If it was just one, or two of the recent negative articles, it wouldn't be that big of a deal and most people would probably forget about it in a few weeks.

But, with bad news, followed by more bad news, followed by stuff like this, people are going to over react to the individual article because they are looking at everything as a whole.

Based off of recent news, I doubt this will be the last non-positive thing we hear about the new MBP.

I hadn't even realized Apple stopped using Iris Pro integrated graphics in the 15-inch model, makes sense since they all use a discrete GPU now - funny tho, you'd think the Iris Pro 580 requires less assembly and it's probably as good as the base Radeon 450.
