Our buddy Fudo over at The Inquirer has just posted some new information regarding ATI's upcoming Radeon X1900 GT GPU. Apparently, yields for R580 are stellar as the assumed 500MHz core frequency for this GPU is supposedly going to be a stunning 575MHz. In similar fashion, the estimated 1GHz memory frequency is now said to be 1200MHz. Obviously, these boosted frequencies will result in some hefty performance gains. Unfortunately, the cost of this board also increased as the card will sell for $350 instead of the $300 many expected. Time will tell if the ~$300 GeForce 7900GT can leverage the $50 advantage or not. Those looking for more information on the Radeon X1900 GT can reference the table on the bottom of the page over at HKEPC.
