![]() Like the GeForce, the Radeon R100 featured a hardware transform and lighting (T&L) engine to perform geometry calculations, freeing up the host computer's CPU. The R100 was built on a 180 nm semiconductor manufacturing process. The card also had been described as Radeon 256 in the months leading up to its launch, possibly to draw comparisons with the competing Nvidia card, although the moniker was dropped with the launch of the final product. The first-generation Radeon GPU was launched in 2000, and was initially code-named Rage 6 (later R100), as the successor to ATI's aging Rage 128 Pro which was unable to compete with the GeForce 256. ![]() It is the basis for a variety of other succeeding products.ĭevelopment Architecture "R100" refers to the development codename of the initially released GPU of the generation. The processors also include 2D GUI acceleration, video acceleration, and multiple display outputs. The line features 3D acceleration based upon Direct3D 7.0 and OpenGL 1.3, and all but the entry-level versions offloading host geometry calculations to a hardware transform and lighting (T&L) engine, a major improvement in features and performance compared to the preceding Rage design. The Radeon R100 is the first generation of Radeon graphics chips from ATI Technologies. ![]() Pentium 4-M and mobile Pentium 4 (340M IGP, 7000 IGP) Radeon 7500 LE card ( Creative Labs Branded)
