device 6670 242W AMD lists Radeon HD 6450/6570/6670 for OEM

Following AMD’s quiet release of the re-branded HD 6700 for OEM, AMD has once again slipped in listings for new HD 6000 family OEM cards, this time based on new chips. First up is the Radeon HD 6670, a direct successor to the HD 5670. Based on the Turks chip, the HD 6670 is a derivative of the Barts architecture. Thanks to minor bumps in SIMD units and clock speeds, the HD 6670 brings about a 24% bump in theoretical shader power, to 768 GFlops, as well as texture fillrate. The memory bandwidth remains identical, while pixel fillrate is boosted by the small clock speed increase. Like the HD 5670, the HD 6670 does not require any PCI-e power connectors, drawing all power from the PCI-e slot. It will be the fastest graphics card not requiring additional power connectors.

Following a similar pattern to the HD 5000 family, the Turks chip, like Redwood, is spread across two series. The Radeon HD 6570 is quite simply a heavily underclocked 6670. In addition, the HD 6570 will also come in GDDR3 variants.

It is the final product listed today, the HD 6450, which receives the biggest boost over the previous generation. The HD 6450 is based on Caicos, and features twice the number of SP and TMU compared to HD 5450 – 160 and 8 respectively. It continues to feature 4 ROPs and 64-bit memory interface, however, and is available in DDR3 and GDDR5 options, with an ambiguous a clock speed of upto 750 MHz (a major improvement over HD 5450).

The HD 6450/6570/6670 OEM are most likely to ship to retail at some point, unlike the HD 6700 which may or may not. The final specifications may vary, but these new OEM products listed offers an indicative preview of upcoming Radeon HD 6000 family products.
