48832G AMDr E RGB More AMD Radeon HD 7000 OEM products revealed

Following the recent reveal of Radeon HD 7670, AMD has now listed an entire range of OEM-only Radeon HD 7000, covering budget oriented graphics cards. As previously expected, these "new" HD 7000 are rebrands of the smallest Northern Islands GPUs – Turks and Caicos, covering HD 7300 to HD 7600. 

Following the recent reveal of Radeon HD 7670, AMD has now listed an entire range of OEM-only Radeon HD 7000, covering budget oriented graphics cards. As previously expected, these "new" HD 7000 are rebrands of the smallest Northern Islands GPUs – Turks and Caicos, covering HD 7300 to HD 7600.

The cheapest product in the HD 7000 line-up will be HD 7350. It is actually a healthy boost over HD 6350, moving from Cedar to Caicos. This means double the SP and TMU, and an option for GDDR5 – with the higher clocked GDDR5 versions with the potential to nearly double performance over HD 6350. HD 7450/7470 are more direct rebrands from HD 6400, with both featuring the Caicos chip at between 625 to 750 MHz, upto 1GB GDDR5.

Moving up, HD 7570 and HD 7670 are essentially direct rebrands of HD 6570 and HD 6670 respectively – both powered by fully enabled Turks. The HD 7500 and 7600 series are left sparse as Trinity based APUs are also likely to be branded under these series. Upcoming Brazos 2.0 APUs will likely fill in the HD 6300 series. 

Both Turks and Caicos are based on the VLIW-5 architecture featuring DX11, fabbed at 40nm. This provides a distinct disconnect between HD 7600 and HD 7700 – the latter of which is codenamed Cape Verde, featuring the brand new GCN architecture (which introduces various new features including DX11.1 compliance) using the 28nm process. 

For now, these entry-level HD 7000 cards are strictly entry-level. However, the HD 6300, 6400 and 6700 series were also first revealed for OEMs in Feb 2011, with a retail release later in April 2011. Thus, these HD 7000 cards may make it to retail, possibly after AMD fills up the new 28nm GCN based line-up – HD 7700, 7800 and 7900.
