The R300 GPU, introduced in August 2002 and developed by ATI Technologies, is its third generation of GPU used in Radeon graphics cards. This GPU features 3D acceleration based upon Direct3D 9.0 and OpenGL 2.0, a major improvement in features and performance compared to the preceding R200 design. R300 was the first fully Direct3D 9-capable consumer graphics chip. The processors also include 2D GUI acceleration, video acceleration, and multiple display outputs. The first graphics cards using the R300 to be released were the Radeon 9700. It was the first time that ATI marketed its GPU as a Visual Processing Unit (VPU). R300 and its derivatives would form the basis for ATI's consumer and professional product lines for over 3 years. The integrated graphics processor based upon R300 is the Xpress 200. Development ATI had held the lead for a while with the Radeon 8500 but Nvidia retook the performance crown with the launch of the GeForce 4 Ti line. A new high-end refresh part, the 8500XT (R250) was supposedly in the works, ready to compete against NVIDIA's high-end offerings, particularly the top line Ti 4600. Pre-release information listed a 300 MHz core and RAM clock speed for the R250 chip. ATI, perhaps mindful of what had happened to 3dfx when they took focus off their Rampage processor, abandoned it in favor of finishing off their next-generation R300 card. This proved to be a wise move, as it enabled ATI to take the lead in development for the first time instead of trailing NVIDIA. The R300, with its next-generation architecture giving it unprecedented features and performance, would have been superior to any R250 refresh. The R3xx chip was designed by ATI's West Coast team (formerly ArtX Inc.), and the first product to use it was the Radeon 9700 PRO (internal ATI code name: R300; internal ArtX codename: Khan), launched in August 2002. The architecture of R300 was quite different from its predecessor, Radeon 8500 (R200), in nearly every way. The core of 9700 PRO was manufactured on a 150 nm chip fabrication process, similar to the Radeon 8500. However, refined design and manufacturing techniques enabled a doubling of transistor count and a significant clock speed gain. One major change with the manufacturing of the core was the use of the flip-chip packaging, a technology not used previously on video cards. Flip chip packaging allows far better cooling of the die by
