'GeForce GTS 450' might have 128-bit memory interface

Now that the GeForce GTX 460 is out, rumor sites are abuzz with news of Nvidia's next DirectX 11 graphics cards—specifically, cheaper models likely to go against AMD's Radeon HD 5700 series. Turkish site Donanim Haber has posted a few details about the GeForce GTS 450, which it says will be here "towards the end of August."

Based on the very loose automated translation, Donanim Haber says the GTS 450 will have a (still-unannounced) GF106 graphics processor, 1GB of GDDR5 RAM, and a 128-bit path to that memory. 128 bits doesn't sound like much, but keep in mind we're talking about GDDR5. With a 1.2GHz clock speed for individual chips, you're looking at an easy 77GB/s.

Also, the story seems to suggest that card makers will be free to design their own boards—for whatever that's worth. A similar report by Expreview hints at a lack of a reference design, but that doesn't seem too likely for a card based on a brand-new GPU. As the blind electrical engineer said, we shall see...

If you're wondering how much the GTS 450 will cost, you probably missed the last round of rumors. A Coolaler report we quoted three weeks ago said GeForce GTS 450 and 455 graphics cards will sell for $129-179, smack dab in Radeon HD 5700 territory.
