TPU spotted a rumor over at DonanimHaber regarding the supposed clockspeeds of AMD's Radeon HD 7950 video card:
eliable sources revealed to DonanimHaber the reference clock speeds of the HD 7950. The core of the HD 7950 will be clocked at 800 MHz, and the memory at 1250 MHz (actual), 5.00 GHz (GDDR5 effective). This, compared to the 925 MHz (core), 1375 MHz (memory actual)/ 5.50 GHz (memory effective) clock speeds of the HD 7970. The HD 7950 will hence be a good overclocker considering the speeds it comes with, there is scope for quite a few factory-OC models from AIBs.
The Radeon HD 7950 is expected to be around $100 to $150 cheaper than the Radeon HD 7970, which would put it around $400 to $450.
