At the end of this month, AMD is expected to let loose upon the gaming world the second graphics card from its Radeon HD 7900 series, and while no official specifications were made public so far by AMD, a report has come out recently to detail the clocks speeds of this upcoming 28nm GCN graphics core.
Citing “reliable” sources with close knowledge of AMD’s plans,
Donanim Haber reports that the upcoming HD 7950 will have a reference GPU clock speed of 800MHz, while the memory will work at 1250MHz (5GHz data rate).
While this last figure seems to pretty much confirm all the rumors that have been spreading around about the HD 7950, the 800MHz graphics core frequency is 100MHz lower than the value touted previously.
Furthermore, this also comes to contradict the specs of a recently leaked Sapphire HD 7950
graphics card, so Donanim Haber’s report should definitely be taken with a grain of salt.
As far as the rest of the
Radeon HD 7950 specs are concerned, we know that the graphics card is based on the same Graphics Core Next (GCN) architecture and Tahiti GPU as that used for the HD 7970, but this comes with four of the core’s Compute Units disabled to turn it into the Tahiti Pro.
The end result is a GPU that includes a total of 1792 stream processors (vs. 2048 in the HD 7970), 112 texture units, 32 ROP units and the same 384-bit wide bus of its elder brother.
The amount of memory installed also wasn’t modified so we are talking about the same 3GB of GDDR5 video buffer.
AMD hasn’t disclosed so far the release date of the Radeon HD 7950, but some rumors suggest this will arrive on January 31. The HD 7950 is expected to be on average US $100-150 (77 to 116 EUR) cheaper than the HD 7970.
