ARM gives a huge discount if you buy their CPU and GPU together. Hard to compete with that on price, so cheap Chinese SoC use ARM. Qualcomm bought adreno from AMD (interestingly an anagram for radeon). Samsung struck a deal to buy from AMD. Intel moved from PowerVR to their own designs. And just like that we're out of major chip makers other than Apple or the occasional specialized SoC that probably doesn't sell in huge volume or rake in the cash. Making things worse, their really cool patents related to early geometry culling expire soon.
