Technology Description:

Compaq delivers a range of industry leading Intel processors for the 5000 and 5100. At the entry point of the mainstream minitower, Compaq will include the newest member of Intel�s family of processors � the Intel Celeron processor. The Celeron is based on the same P6 micro-architecture as the Pentium II, delivering Pentium II technology and superior multimedia performance at entry/mainstream PC prices. Moving up the mainstream minitower line, Compaq will include the Intel Pentium II 300MHz processor as well as Intel�s new .25 micron technology in the Pentium II 333 and 350MHz processors at the upper end of the line. Compaq is dedicated to delivering value, reliability and performance. With the Intel Inside processor family, everyone can feel confident that they are getting the best value and performance in the industry.

The Intel Celeron and Pentium II processors offer incredible 3D, multimedia, and Internet performance for the mainstream computer user. Combined with ATI 3D Rage LT Pro 2X AGP graphics, the Presario 5000 series with Intel Celeron provides an unbeatable 3D and multimedia performance. PC consumers will benefit from this technology through more realistic 3D game play, better video playback, and more enjoyable visual computing experience. Productivity is enhanced too with faster Java processing on the Internet meaning your Internet shopping and browsing time is reduced. In addition, spreadsheet applications run faster. Overall, the Intel family of processors provide an unbeatable computing experience.

Key Supporting Features:

Dynamic Execution Core

The Dynamic Execution Core includes three critical features that make up the cornerstone of Celeron and Pentium II performance. The first is a sophisticated 4-bit branch prediction scheme that speeds up instruction processing by predicting where the instructions should go within the processor. The second is out-of-order execution: execution sequence is based on dataflow analysis which schedules instructions for execution based only on data dependencies regardless of actual sequence in the flow of program logic. This feature exploits maximum parallelism by trying to utilize the 2 integer and 1 floating point pipelines for every clock tick since multiple instructions can have their data dependencies satisfied and thus ready to execute simultaneously. The third is Speculative Execution, which increases the rate of execution by speculatively executing instructions that might be needed in the near future.

MMX Technology

MMX technology includes new instructions and data types that allow applications to achieve a new level of performance. Using the Single Instruction, Multiple Data (SIMD) technique, these instructions process multiple data elements in parallel which, depending on the application, can enhance performance by up to 50% or more over standard Pentium processors. Application types that benefit most from MMX technology are 2D and 3D graphics, audio, speech recognition, video codecs, and data compression. MMX instructions using the SIMD technique are designed to speed up the algorithms in these applications to improve the performance and quality of activities such interactive video, virtual reality, and realistic 3D environments.

Dual Independent Bus Architecture (for Pentium II)

The Dual Independent Bus Architecture, first seen in Intel�s Pentium Pro processors, is designed to address bandwidth limitations in the current PC platform architecture. The name derives from the fact that two (dual) independent buses reside on the Pentium II processor as opposed to a processor (like the Pentium) that has a single bus architecture. The two buses are the L2 cache bus and the processor-to-main-memory system bus. The Pentium II processor can use both buses simultaneously to move as much as two times more data than a single bus architecture processor. Additionally, the L2 cache bus scales with the processor and runs at twice the speed of a standard Pentium processor. This pipelined system bus enables simultaneous parallel transactions instead of singular sequential transactions. The result of these Dual Independent Bus architecture improvements is an increase of three times the bandwidth performance over a single bus architecture.

Best Demonstration to show off Technology:

VideoPhone: Connect a USB video camera and show off the processing capabilities. Explain how the digital video signals from the USB camera are actually being processed and managed by the processor. There is no need for an add-on card to perform the video capture and display.

AGP 3D Game: Incoming, the most exciting new AGP game. When running the game point out the vivid colors and textures especially in the sky and the buildings. Be sure to show off the realism of the cannons blasting off rounds and the structures exploding.
