NASA's Perseverance rover, which recently made history landing on the surface of Mars, is powered by the same processor used in an iMac more than 23 years old.
As reported by NewScientist (via Gizmodo), the rover includes the PowerPC 750 processor, the same chip used in the G3 iMac in 1998.
The main chipset is the same; however, there are differences between the version of the processor shipped in a consumer computer and the one exploring space. The processor in the rover is built to withstand temperatures between -67 and 257 degrees Fahrenheit (−55 and 125 degrees Celsius) and comes with an added $200,000 price tag.
The PowerPC 750 processor was ahead of the game for its time, featuring a single-core, 233MHz processor, 6 million transistors (compared to today's 16 billion in a single chip), and based on 32-bit architecture.
Apple used PowerPC chips in Mac computers until it transitioned to Intel in 2005. Right now, Apple's going through a similar change, moving away from Intel to deploy its own custom Apple silicon in Macs.
Bethesda's beloved role-playing game "The Elder Scrolls V: Skyrim" has reached multiple generations of consoles since its 2011 debut, but it never officially came to the Mac. A new unofficial project called SkyrimMT now aims to make playing and modding it on Apple silicon Macs easier than ever.
Mac owners have found ways to play Skyrim over the years, including installing Windows through...

In a memo shared with Apple Stores and Apple Authorized Service Providers this week, and later obtained by MacRumors, Apple provided technicians with guidance on how to diagnose and address the iPhone Duo's inner display cracking issue.
If a customer reports the issue, Apple advised technicians to inspect the iPhone Duo and repair or replace it in accordance with their standard procedures....

While the new iPad mini has an OLED display, the device does not support ProMotion, meaning the display's refresh rate is limited to 60Hz instead of 120Hz.
ProMotion support would have allowed for the iPad mini's refresh rate to automatically adjust from 10Hz to 120Hz depending on the content being displayed, but evidently Apple has kept the feature exclusive to the iPad Pro among iPad...
Because super-reliability is more important than compute power. The G3 is also used e.g. as mission computer in fighter jets. The feature is called fail-safe
if a more than two decade old processor is good enough to find out evidence of extraterrestrial past life, then I got no excuse to be buying anything that Tosser Prosser is predicting anytime soon
It's also radiation hardened, which is where the price tag comes from (and also the most important thing setting it aside from the actual PowerPC 750 found in the iMac G3)
Anything launched into space has typically been in a multiple years long project, sometimes decade(s) long. It also usually costs a gazillion dollars.
What matters most is reliability and predictability... especially for something going millions (or billions) of miles away and not coming back that we can’t send astronauts to physically fix.
Most of the closed loop systems aboard aircraft, spacecraft, submarines, weapons and similar applications have very old, proven, but mundane processors and operating systems aboard... the last thing you want is “the new kid on the block” when the stakes are so high. Although parts of it are modernized as needed, the ECU in a typical car has the processing power no more than a Texas Instruments calculator... some of the software in Boeing and Airbus jets is virtually unchanged since the 1980s as well.
