An Intel attempt to pair the company's processors with integrated graphics from AMD is officially coming to an end.

On Tuesday, Intel quietly issued a product notice, saying it was discontinuing the company's Kaby Lake-G processors, which were born from a rare team-up between the chip maker and rival AMD.

Back in Nov. 2017, Intel announced it was creating a special line of chips for PC gaming hardware that would pack an Intel Core H-series processor with a "Vega M" GPU chip from AMD's Radeon group, which is best known for creating dedicated graphics cards.

Although the partnership took the chip industry by surprise, the resulting Kaby Lake-G processors were powerful, offering Core i7 performance and some impressive AMD-backed graphic capabilities on a single chip. In 2018, Intel began introducing the Kaby Lake-G processors into PC models such as the Dell XPS 15 2-in-1 convertible laptop and Intel's own "Next Unit of Computing (NUC)" line of mini-PC desktops. However, the chips never appeared to gain widespread adoption among device makers.

Why Intel is abandoning the chip line isn't entirely clear. But the company's rivalry with AMD has been heating up; the new Ryzen and Threadripper processors from AMD have proven to be competitive alternatives to Intel's desktop and laptop chip lines.

At the same time, Intel is preparing to enter the dedicated graphics card market in 2020, putting it in direct competition with AMD's Radeon business. The company also launched new "Ice Lake" chips, which boast their own impressive Intel-designed GPU capabilities.

Intel didn't immediately respond to request for comment. Tuesday's notice from company simply says market demand for the Kaby Lake-G chips has shifted to other Intel products. On July 31, 2020, it will officially end all shipments for the chips.
