NordicHardware has procured a document, allowing them to provide some insight into, yet unannounced, AMD graphics solutions powered by the RV730 mid-range and, RV710 low-end GPUs.
Starting with the mid-range RV730, it is suggested that there will be an SKU offering 512 MB of memory, running at 700 MHz, which is presumed to be the basic RV730 offering. Moving towards the mid-range offerings, some diversification as to the amount and type of memory chips used, emerges. Running at memory speeds of 900 MHz, a 512 MB part, using Hynix memory chips, together with a 1 GB part, using Samsung memory chips, will take up duties in this category.
Lastly, a 512 MB part, utilising Hynix memory chips, running at 1000 MHz will perhaps head up the high-end of the RV730 spectrum, perhaps favouring memory speed, over quantity.
The parts may be categorised by different GPU speeds, yet information regarding this is scarce at present. The report surmises however, that the basic RV730 offering, furnished with 512 MB of memory running at 700 MHz, could be born as the HD 4650, whilst the other three part variations would be known as the HD 4670.
The low-end RV710 appears to be a simpler affair. It is indicated that both solutions which, likely, would be named as the HD 4450 and 4470, will be fitted with either 512 MB of Hynix GDDR3 memory, or 1 GB of Samsung GDDR3 memory, running at speeds of 800 MHz. The presumed differentiation will perhaps again, be made via the final GPU core speeds, set by AMD.
AMD is apparently hard at work on setting the final configurations for the upcoming RV730 and RV710 parts and, it will be interesting to see whether the top-to-bottom HD 4000 series line-up will be as impressive, as the results seen so far from the RV770.
