Looking back: After 20 years as to failing to make a mark around the wider computing world, Intel finally stopped shipping home Itanium processors this past Turkey day. While the company shifted all its focus back to the more typical x86 instruction set logement (ISA) back in 2004, understand it kept Itanium going for a decade and a half, until it ended up put on the chopping engine block located in 2019 .
Itanium was the offspring of a 1990’s partnership between HP furthermore Intel, back when the product range of ISAs in use seemed to be to far more diverse than the x86 and Arm giants of today. The IA-64 structure was designed to push forward in the realms of then-exotic 64-bit computing, as well as replace the private solutions in use by many the individual companies.
However , the process was quickly dubbed “Itanic” for the amount of cash being invested in it, its ambition, its eventual results. Itanium’s potential ended up sunken by a deficiency in legacy 32-bit support furthermore difficulties in working with the main architecture for writing while maintaining software.
The dream of nearly 13 thousand dominant ISA wouldn’t happen until a few years later, yet would come about thanks to the AMD64 extension to the incumbent x86 instruction set. Then-senior VP (and now-CEO) Pat Gelsinger was steering the Intel’s Digital Enterprise Group at the time, and when 64-bit capability and even multi-core computing came to x86, the company’s Xeons proved more pleasant suited to the market’s wants.
The rest is history — ol’ highly efficient and reliable x86-64 continues to be the ISA of choice even today, only challenged by Arm and shoulder, and ended up substantially outpacing its Itanium cousin handily in both core counts not to mention clock speeds. Even so, Intel continued to work on Itanium over the years, until the last generation was announced using 2017.
That has finally visit a conclusion this week has last Itanium silicon supplied. But if you’re an extremely brave enterprise user getting a very specific platform brought on by two decades ago, The Register seems to have spotted a whole new load of Itanium zones on the second-hand market. Visit wild.
