New 350 and 400-MHz Pentium® II Processors Announced for Performance Segments
Intel's highest performance processor integrates the best attributes of the P6 microarchitecture—Dynamic Execution, Dual Independent Bus (DIB), a multi-transaction system bus, plus Intel's media-enhancing MMX™ technology. At 400 MHz, the Pentium II processor delivers up to a 20% performance boost over the 333 MHz Pentium II processor and improves system bandwidth and performance by increasing the system bus speed from 66-MHz to 100-MHz. The new 350 and 400 MHz Pentium II processors are targeted for professionals, avid PC users, and PC gamers, or the Enthusiast and Professional desktop segments. They also meet the needs of entry-level to mid-range servers and workstations.

Pentium® II Xeon™ Processor to Be New Brand Name for Processors Specifically Designed for Servers and Workstations
Intel announced Pentium II Xeon (pronounced "ZEE'-on"), a new brand name for a line of processors that will be designed specifically to meet the needs of midrange and higher server and workstation applications. Intel's Pentium II Xeon processor will offer leadership performance and scalability for those manufacturers designing workstations and servers. Intel will introduce the processors in mid-1998 with system products to follow thereafter.

The Pentium II processor is the most advanced Intel Architecture processor. Delivering Intel's highest performance on the three vectors of performance—floating point, integer, and multimedia—the Pentium II processor provides ample processing power needed in today's operating systems and new applications like those in business media, PC imaging, communications, and gaming.
The Pentium II processor family supports the evolution of computing technology in four important ways:
- Dual Independent Bus (DIB) architecture
- Dynamic Execution
- Intel MMX™ technology
- Single Edge Contact Cartridge (S.E.C.C.)
The Pentium II processor is available in 233MHz, 266 MHz ,300 MHz, 333, 350 and 400 MHz versions for desktops, workstations and servers. Pentium II processors feature Intel's MMX technology to enhance multimedia and communications processing. They also use the high-performance Dual Independent Bus (DIB) architecture to deliver greater system bandwidth to complement their high processing power. The Pentium II processor also includes 32KB of level one (L1) cache (16K data, 16K instruction), and a 512KB level two (L2) cache running at ½ the speed of the processor core. Error Correction Code (ECC) memory is now available on the L2 cache. This type of cache better enables servers and workstations to operate in business environments where data integrity and reliability are essential. The new 100MHz system bus for Slot 1 processors will support new high speed SDRAM technology.
The Intel Celeron™ processor at 266MHz is targeted for the entry level, basic PC. This platform is good for first time PC users. It performs the basic functions well: e-mail, internet access, basic productivity applications, and young children education. The Celeron processor is software compatible with Pentium II processor and carries the same quality expected from Intel.
In 1999 Intel expects to be in production with the first member of a new family of IA-64* processors, code named the Merced™ processor. This processor will be produced on Intel's 0.18 micron process technology, which is currently under development. The Merced processor will extend the Intel Architecture with new levels of performance and features for servers and workstations. Merced processors will be compatible with all the software that currently operates on 32-bit Intel processor-based machines. As IA-64 processors become established with the Merced processor, Intel will continue to expand its 32-bit product offerings. In 1999, Intel processors will span from 32-bit products for office, home and mobile users to the most powerful 64-bit products moving Intel into new, higher-end workstations and server market segments. For more information on IA-64 processors and Merced, please visit the Intel Microprocessor Forum site.

Together, systems designed with the Pentium II processor and the Accelerated Graphics Port (AGP) make multimedia software come alive. Greater processing power and video bandwidth allow for better 3D graphics, richer textures, higher resolution, and smoother animation than ever before. All this provides a more lifelike experience for games, educational and hobby software. The Pentium II processor also enables new capabilities in PC imaging, video editing and playback, and audio re-mixing. Improved video performance means crisper and clearer images during video playback and editing. Pentium II processor-based systems bring home rich and exciting PC entertainment experiences with new media technologies like host-based DVD.
In business, Pentium II processor systems are available for desktop, server and workstation platforms. The Pentium II processor family is fully compatible with previous generations of Intel Architecture processors. Both small and large businesses benefit from optimal performance with applications running on advanced operating systems such as Windows* 95, Windows NT* and UNIX*.
With the new 100 MHz system bus, users will experience even higher overall system performance, allowing for expanded I/O operations based on higher speed communication with the system's SDRAM memory.
