Intel's Gregory Bryant, vice president and general manager of Intel’s desktop clients platform, has gone on record during a speech at the J.P. Morgan forum saying that the company's IGP (integrated graphics processor) called Iris and Iris Pro are fast enough for casual and mainstream gamers and that they would no longer need a discrete graphics solution. That statement in itself does not sound unreasonable or outlandish as Intel IGP performance has steadily increased over the years and eaten into AMD and NVIDIA's low end share.
However, Mr. Bryant also stated that Iris and Iris Pro can outperform 80% of discrete graphics chips , “We have improved graphics 30 times what they were five years ago,” but admits that Intel has done a poor job communicating the benefits of integrated graphics. According to Steam's hardware survey, as of December 2015, Intel currently holds 18.66% of the overall share with 54.61% going to NVIDIA and 26.23% to AMD. This market share is virtually unchanged from December 2014 where Intel had a share of 18.88% so it seems they do have some work to do if they want to increase their appeal to gamers.
Unlike NVIDIA, AMD manufactures APUs that compete with Intel's IPG solutions but with the release of Iris 6200 pro, Intel has taken a significant lead over AMD and has even approached NVIDIA's discrete GeForce GTX 750 performance at the entry level. With AMD Zen APUs possibly being released in 2017, it may give the firm the opportunity to finally take back the low end APU performance from Intel.
