The AMD-K5 processor is the first in a broad range of high-performance options from AMD. The AMD-K5-PR75 and AMD-K5-PR90 processors offer the best value for 64-bit, 5-class performance and provide complete Microsoft Windows operating system and x86 software compatibility. A plug-in alternative for the Pentium, the AMD-K5 processor is an ideal choice for entry-level desktop PCs. The AMD-K5 processor's fifth-generation performance stems from AMD's independently developed four-issue superscalar core architecture with six parallel execution units arranged in a five-stage pipeline. This architecture contains 16-Kbyte instructions and 8-Kbyte data cache, providing highly efficient instruction throughput. The result is a processor with the power to run 32-bit operating systems and applications, as well as the huge installed base of x86 software. How is the performance of the AMD-K5 processor measured? To help PC manufacturers and their customers evaluate the performance of AMD-K5 processor, AMD uses the R-Rating, an apples-to-apples processor performance rating system that employs the industry-standard Winstone 96 benchmark. For example, based on Winstone 96 tests using identical PC configurations, the AMD-K5-PR90 processor has a R-Rating of "90," meaning it offers performance greater than or equal to a 90-MHz Pentium. How does the AMD-K5 compare in competitive benchmarks? Listed below are the Winstone 96 benchmarks for the AMD-K5-PR75 and AMD-K5-PR90 processors: AMD-K5-PR75 - 49.1 Pentium 75 - 47.4 AMD-K5-PR90 - 56.7 Pentium 90 - 54.9 Benchmark Configuration: * FIC PA2002 motherboard * VIA Apollo Master Chipset * 16-Mbyte EDO DRAM * 256-Kbyte L2 cache* * PCI Diamond Stealth 64 3200 video card (640 x 480 x 256) * Diamond GT video drivers 4.02.00.218 for Windows 95 * Quantum Fireball 1.2 GB EIDE hard drive * *(Size remains consistent. Type differs from system to system) Is the AMD-K5 processor a hardware-compatible Pentium alternative? Yes. AMD designed the independently developed AMD-K5 processor to be hardware compatible with the Pentium. This P54C compatibility enables PC manufacturers to take advantage of existing 586-class designs and infrastructure. A plug-in processor solution for Pentium-compatible motherboards, the AMD-K5 processor minimizes redesign costs and offers a truly viable Pentium alternative. What are the key features and benefits of the AMD-K5 processor? Features Benefits --------------------------------------------------------------------------- Independent architecture Enables freedom of choice with viable alternative P54c(Pentium) hardware Leverages exiting infrastructure compatibility Minimizes redesign costs AMD-K5 superscalar core Delivers Pentium performance 16-Kbyte instruction cache,8-Kbyte data cache Provides ideal processor solution for 64-bit desktop PCs Full out-of-order Offers foundation for higher-performance options speculative execution/ completion Dynamic branch prediction Integrated 80-bit floating point unit (FPU) Enhanced SMM and clock control --------------------------------------------------------------------------- Which motherboard manufacturers support AMD-K5 processor? AMD has validated the following motherboard manufacturers that support the AMD-K5 processor. AMD-K5 motherboard validation consists of electrical and functional testing to ensure that the motherboard design meets the basic functional requirements needed to operate using an AMD-K5 processor. This list is not intended to represent all motherboards available on the market that support this product, but is a sampling of popular motherboards that have been verified by AMD to support the AMD-K5 processor. This information is updated on a regular basis.

Please contact your local motherboard representative for assistance. What are the motherboard design requirements? * Vcc Spec (operating voltage) = 3.45 V - 3.60 V * Heatsink Required = Yes * Fan Required = Yes Please consult the AMD-K5 Data Sheet for updates concerning valid operating voltage options. When will AMD-K5 processors be available? AMD-K5 processor volume production will begin in the second quarter of 1996 in a 296 pin SPGA (staggered pin grid array) package. What is the difference between the K5 and the SSA/5? K5 and SSA/5 are codenames for different engineering revisions of the AMD-K5 processor. Just as Intel improved circuit speed and process technology in moving Pentium from the P5 to the P54C revision, AMD is making improvements in logic, circuit speed, and process technology between the SSA/5 and K5 revisions. Together, these improvements will result in higher performance options of the AMD-K5 processor. How are the Am5X86TM and the AMD-K5 processors different? The Am5X86 processor delivers 586 performance while it leverages 4th-generation system designs/cost and utilizes 32-bit existing infrastructure. The AMD-K5 processor is based on the AMD-K5 superscalar architecture and has a P54C hardware compatible pinout, positioning it as a compatible and viable 5th-generation alternative to Pentium. The AMD-K5 processor utilizes 64-bit existing infrastructure.
