AMD have four OEM-only AMD Radeon HD 7000 series products which aren't based on the new Graphics Core Next architecture seen in the AMD Radeon 7700 and up cards.
The cards are the HD 7350, 7450, 7470, 7570 and 7670 graphics solutions. Each of these cards is a rebrand, and the reason they exist is simple - APU's.
The Radeon HD 7350 is a rebadge of the AMD ATI Radeon HD 5450.
The HD 7450 and 7470 are rebadges of the AMD Radeon 6450. The difference between the two is the core clock and the memory type. The 7470 gets the higher engine clock and GDDR5, the 7450 gets lower clock and DDR3 memory to save power.
The HD 7570 is rebaged from the AMD Radeon 6570, and the HD 7670 is predictably enough based on the HD 6670.
So, Cedar, Caicos and Turks live on in the Radeon HD 7000 series, keeping the VLIW5-based architecture alive. These are also used in the mobility segment, AMD Radeon HD 7000M are 40nm VLIW5 parts, too. Why? Bigger numbers are better. So for 2012 notebooks with 2011 APU's in them, you need 7000 series graphics which means you need rebands to go with them. Ain't marketing fun?
