In an attempt to plug a hole in its product stack between the Radeon HD 7670 and the Radeon HD 7750, AMD could launch a new Radeon HD 7700 series SKU, the HD 7730. Based on the 28 nm "Cape Verde" silicon, the chip could feature 448 stream processors based on the Graphics CoreNext architecture, 28 TMUs, 16 ROPs, and a 128-bit wide GDDR5 memory interface, holding 1 GB of memory.
An MSI-branded HD 7730 is already doing rounds in the Chinese local market, indicating the SKU is designed for retail, and not just the OEM channel. The MSI card features 800 MHz core clock speed, with its memory clocked at 1125 MHz (4.50 GHz GDDR5-effective). With the HD 7730, AMD could also be going after NVIDIA's GeForce GT 640. It remains to be seen if the HD 7730 is a global product. The MSI card features retailer stickers from Taiwan-based retailers.
The source put the card through a few tests.
