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.

Apple's iPhone development roadmap runs several years into the future and the company is continually working with suppliers on several successive iPhone models at the same time, which is why we often get rumored features months ahead of launch. The iPhone 18 series is no different, and we already have a good idea of what to expect for the iPhone 18 Pro and iPhone 18 Pro Max.
One thing worth...
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 [S]Tosser[/S] 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)
