ATI entries cover all cards sold under the ATI Radeon brand, including AMD-era chips still branded ATI (HD 2000 through HD 5000 series, 2007–2010). The brand-on-the-box rule applies: if the retail box said "ATI Radeon," it is listed here. AMD-branded Radeon cards from the HD 6000 series onward are listed under AMD.
