INPAI reports that AMD is preparing to release a new product based on Juniper. This will be a 640SP product, lower than the HD 5750 (720) and the HD 5770 (800). While logic would suggest that this product should effectively be known as HD 5730, Inpai suggests that it will be simply an “update” to the HD 5670.

It is rumoured to feature a core frequency of 750 MHz, while the GDDR5 memory is the same as the HD 5670 – 4 GHz mated to a 128-bit memory interface.

INPAI reports that AMD is preparing to release a new product based on
Juniper. This will be a 640SP product, lower than the HD 5750 (720) and
the HD 5770 (800). While logic would suggest that this product should
effectively be known as HD 5730, Inpai suggests that it will be simply
an “update” to the HD 5670.

It is rumoured to feature a core frequency of 750 MHz, while the GDDR5
memory is the same as the HD 5670 – 4 GHz mated to a 128-bit memory
interface.

This does offer a formidable upgrade to the 400SP HD 5670, though we would much prefer a HD 5690 or HD 5730 nomenclature.

The catch is, it is likely to be released only in China. This is not unprecedented, as a remarkably similar product, the HD 3690 was a China-exclusive. At the time, the HD 3690 provided a remarkable price/performance ratio, and it is likely the “new” HD 5670 will follow in its footsteps. Like the HD 3690, the “new” HD 5670 is also a crippled version of the performance cards in the next segment – designed to increase yields.
