21850J/0-February 2000 Preliminary Information AMD-K6®-2 Processor Data Sheet robust Socket 7 platform. See "Super7™ Platform Initiative" on page 3 for more information. AMD is the world's second-leading supplier of Windows-compatible PC processors, having shipped more than 120 million x86 microprocessors, including more than 60 million Windows-compatible processors. With its combination of state-of-the-art features, industry-leading performance, high-performance 3DNow! technology and multimedia engines, x86 compatibility, and low-cost infrastructure, the AMD-K6-2 is the superior choice for mainstream personal computers. 1.1 Super7™ Platform Initiative AMD and its industry partners launched the Super7 platform initiative in order to maintain the competitive vitality of the Socket 7 infrastructure through a series of enhancements, including the development of an industry-standard, 100-MHz processor bus protocol. In addition to the 100-MHz processor bus protocol, the Super7 initiative includes the introduction of chipsets that support the AGP specification, and support for a backside L2 cache and frontside L3 cache. Currently, over 40 motherboard vendors and all major BIOS and chipset vendors offer Super7 platform-based products. Super7™ Platform Enhancements The Super7 platform has the following enhancements: s 100-MHz processor bus-The AMD-K6-2 processor supports a 100-MHz, 800 Mbyte/second frontside bus to provide a high-speed interface to Super7 platform-based chipsets. The 100-MHz interface to the frontside Level 2 (L2) cache and main system memory speeds up access to the frontside cache and main memory by 50 percent over the 66-MHz Socket 7 interface-resulting in a significant increase of 10% in overall system performance. s Accelerated graphics port support-AGP improves the performance of mid-range PCs that have small amounts of video memory on the graphics card. The industry-standard AGP specification enables a 133-MHz graphics interface and will scale to even higher levels of performance. s Support for backside L2 and frontside L3 cache-The Super7 platform has the 'headroom' to support higher-performance AMD-K6 processors, with clock speeds scaling to 550 MHz and beyond. The Super7 platform also supports the AMD-K6-III processor which features a full-speed, internal backside 256-Kbyte L2 cache designed to enable new levels of performance to leading-edge desktop systems. This processor also supports an optional 100-MHz external L3 cache for even higher-performance system configurations. Chapter 1 AMD-K6®-2 Processor 3
