You know those Nvidia GF100 derivatives we wrote about? German website 3DCenter claims to have gotten the scoop from a "trusted source" about one of those derivates, the GF104, and it's posted a cornucopia of unconfirmed details.
According to 3DCenter, the GF104 will feature 256 shader units, 32 ROPs, and a 256-bit GDDR5 memory interface—not quite exactly a halved GF100. You can reportedly expect this future chip in three products, which the site tentatively calls the GeForce GTS 450, GeForce GTS 440, and GeForce GTS 430. The first of those will reportedly cost €200-230 in Europe, so likely about the same number of dollars over here. The middle child should set you back €160-180 (again, likely $160-180), and the cheapest will fall below that.
On the performance side of things, 3DCenter believes the rumored GeForce GTS 450 will go head on against the new Radeon HD 5830, delivering less raw compute power but beefier rasterization capabilities. That formula could translate into better overall gaming performance, assuming the details in this report are at least somewhat close to the truth.
Yesterday's Fudzilla story talked of unnamed GF100 derivatives being out this summer, so perhaps that schedule applies to the GF104. That would be good news for consumers, since a competitive GF104 could trigger a price war in the mid-range graphics market. (Thanks to Fudzilla for the link.)
