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 today announced the M6 chip, its first built using a 2-nanometer process and featuring a Dual 16-core Neural Engine.
Apple says the 2nm process packs greater transistor density into a smaller die, contributing to the chip's overall gains in performance and power efficiency.
The M6 chip features a larger, more powerful 12-core CPU, two more cores than the M5, made up of two super...
Apple today announced the M5 Ultra, which the company says is its most powerful chip ever.
The M5 Ultra is built by connecting two dual-die M5 Max chips using Apple's next-generation UltraFusion technology, which is the first time Apple has used a quad-die architecture in an M-series chip. UltraFusion increases inter-die bandwidth to over 4.4TB/s and connection density by more than 6x,...
Images claiming to show the inside of an Apple-made AI server, believed to power Private Cloud Compute, surfaced online this week, offering a first look at how the hardware is laid out.
The images were shared earlier this week by the X user @hsuchingpo, an account with a track record of Apple hardware and prototype leaks. Captioned simply "Apple M5 Server," the leaker said the hardware is "mo...
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.
