Itanium processors are sometimes used today for servers. Itanium processors where originally designed by HP and Intel with Intel making producing them, and several manufacturers of systems used them; nowhere as many systems used as originally hoped for. By now mostly HP still supports systems using these chips.

In 2019, Intel announced that Itanium CPU family shipments will cease on July 29, 2021.

Put simply, Itanium failed in part because Intel pushed a task into software that software compilers aren’t capable of addressing all that effectively. The challenges Itanium faced were formidable and it consumed a great deal of power.

Since then, the clock rate of production processors has increased much more slowly, with performance improvements coming from other design changes. As of 2011, the Guinness World Record for the highest CPU clock rate is 8.42938 GHz on an AMD FX-8150 Bulldozer-based chip.

Intel has announced six new Comet Lake-H 10th generation mobile processors that offer up to eight cores and 16 threads as well as a massive 5.3GHz peak boost frequency – the fastest of any Intel CPU to date – even faster than the desktop Core i9-9900KS – and the first mobile processors to top 5GHz.

Xeon is Intel’s CPU lineup, and it’s aimed primarily at business workstations and servers. These CPUs typically offer more cores than mainstream PCs, but the clock speeds are a little wonky when compared with their Core i7 and i9 counterparts. Xeon chips are far more power-hungry and get a lot hotter.

Xeons are CPUs made more for servers and rendering, while the i9 is a much faster processor. The reason why people use Xeons is because there are motherboards that are built to fit more than 1 Xeon inside, and for rendering more cores are needed to multitask heavily.

Intel Xeon is practically built for workstation computers. The large number of cores and advanced RAM functions give it enough processing power and speed to handle the most intensive creative applications, from computer-aided design (CAD) to 4K video editing to 3D rendering.
