Graphics Double Data Rate 7 Synchronous Dynamic Random-Access Memory (GDDR7 SDRAM) is a type of synchronous graphics random-access memory (SGRAM) specified by the JEDEC Semiconductor Memory Standard, with a high bandwidth, "double data rate" interface, designed for use in graphics cards, game consoles, and high-performance computing.
The Radeon R100 is the first generation of Radeon graphics chips from ATI Technologies.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.
Drivers were also provided in operating systems including Windows 95, Windows NT, the Mac OS, OS/2, and Linux. [3] ATI also shipped a TV encoder companion chip for RAGE II, the ImpacTV chip. RAGE II was integrated into several Macintosh Computers, including the first revision of the Macintosh G3 (Beige) and the Power Mac 6500.
ATI stopped support for Mac OS 9 after the Radeon R200 cards, making the last officially supported card the Radeon 9250. The Radeon R100 cards up to the Radeon 7200 can still be used with even older classic Mac OS versions such as System 7, although not all features are taken advantage of by the older operating system.

The R200 is the second generation of GPUs used in Radeon graphics cards and developed by ATI Technologies.This GPU features 3D acceleration based upon Microsoft Direct3D 8.1 and OpenGL 1.3, a major improvement in features and performance compared to the preceding Radeon R100 design.
2 The effective data transfer rate of GDDR5 is quadruple its nominal clock, instead of double as it is with other DDR memory. 3 The TDP is reference design TDP values from AMD. Different non-reference board designs from vendors may lead to slight variations in actual TDP.
