Back in December, we discussed how the mobile graphics cards were simply a re-branding of its current HD 6000 series. This holds true with AMD's new HD 7000 OEM series graphics cards. The cards are designed specifically for OEM vendors only and are tailored toward the low-end and mid-range market. The OEM series is based on the current VLIW5 design and not the new GCN architecture seen with the Radeon HD 7970.
Looking at the Radeon HD 7670 and HD 7570, they're the same specifications as the Radeon HD 6670 and HD 6570. The Radeon HD 7470 is the same as the 750 MHz version of the Radeon HD 6450, while the HD 7450 matches the 625 MHz version of the HD 6450.

Update 01/06/2012: Yesterday, the crew at AnandTech were on the same page as we were with the re-branding of the Radeon HD 7000 OEM series. Through the OEM site we found, AnandTech did a little more digging around and found the Radeon HD 7350 is not based on the Caicos but the two year old Cedar based HD 5450. In review of the specifications, it was found the HD 7350 doesn't support DisplayPort 1.2, which was a feature introduced with Northern Islands.
