German site
Hardware-Infos brings detailed specifications for RV730-based Radeon HD 4650
and 4670 GPUs. Reportedly, both offerings will feature 320 stream
processors-just like today's Radeon HD 3850 and 3870-but with memory interfaces
only 128 bits wide. Core clock speeds will range up to 750MHz for the Radeon HD
4670, while memory will top out at 1,000MHz (presumably an "effective"
2,000MHz). The spec sheet mentions 480 gigaFLOPS, 32GB/s of memory bandwidth,
and a 59W power envelope for the 4670, compared to a respective 429 gigaFLOPS,
53GB/s, and 95W for the Radeon HD 3850. As for the 4650, that card will crank
out a tamer 384 gigaFLOPS with up to 21.3GB/s of memory bandwidth. Assuming
those specs didn't originate from a demented homeless man, the Radeon HD 4670
could turn out to be a fairly potent low-end offering.
