IMac Pro
The iMac Pro is an all-in-one personal computer and workstation sold by Apple Inc. from 2017 to 2022. At its release, it was one of four desktop computers in the Macintosh lineup, sitting above the consumer range Mac Mini and iMac, and serving as an all-in-one alternative to the Mac Pro. After the cylindrical Mac Pro redesign went years without any update, Apple hosted a roundtable with journalists promising a redesign and commitment to professional Mac computers; the iMac Pro was introduced in the interim before the revised Mac Pro shipped in 2019. Externally, the iMac Pro is nearly identical to the consumer iMac, albeit in a darker finish. Apple redesigned the internals to provide cooling for workstation Intel Xeon processors and AMD Vega graphics. The iMac Pro was positively received by critics, who praised its quiet performance and appeal as an all-in-one machine, while criticizing its lack of expansion and upgradability, as well as the drawbacks it retained from the r ...

The iMac is a series of all-in-one desktop computers designed, manufactured, and sold by Apple Inc. Between 2006 and 2022, the iMac series used chipsets based on Intel architecture. While sold, it was one of three desktop computers in the Mac lineup, serving as an all-in-one alternative to the Mac Mini, and sat below the performance range Mac Pro. It was sold alongside a higher-end, Xeon-based iMac Pro from 2017 to 2021. The earliest Intel iMacs reused the same white polycarbonate enclosure as the iMac G5. Later models shifted to aluminum and plastic, and then a unibody aluminum case. The iMacs released after October 2012 also featured a much thinner display, with the edge measuring just 5 mm. This design would persist until the line was discontinued. As part of the Mac transition to Apple's own processors, the Intel-based iMac was succeeded by the Apple silicon iMac beginning in 2021. Apple discontinued the 21.5-inch Intel iMac the same year, with the 27-inch model ...

Graphics Processing Unit
A graphics processing unit (GPU) is a specialized electronic circuit designed for digital image processing and to accelerate computer graphics, being present either as a discrete video card or embedded on motherboards, mobile phones, personal computers, workstations, and game consoles. GPUs were later found to be useful for non-graphic calculations involving embarrassingly parallel problems due to their parallel structure. The ability of GPUs to rapidly perform vast numbers of calculations has led to their adoption in diverse fields including artificial intelligence (AI) where they excel at handling data-intensive and computationally demanding tasks. Other non-graphical uses include the training of neural networks and cryptocurrency mining. History 1970s Arcade system boards have used specialized graphics circuits since the 1970s. In early video game hardware, RAM for frame buffers was expensive, so video chips composited data together as the display was being scann ...
