Pentium

III Processor for the PGA370

Socket at 500 MHz to 866 MHz

Product Features

Available in 866, 800EB, 733B, 667B,

600EB, and 533EB MHz speeds to support a

133MHz system bus ("E" denotes support

for Advanced Transfer Cache and Advanced

System Buffering; "B" denotes support for a

133 MHz system bus

See Table 1 for a summary of features for

each line item.)

Available in 850, 800, 750, 700, 650, 600E,

550E, and 500E MHz speeds for support of a

100 MHz system bus frequency (‘E’ denotes

support for Advanced Transfer Cache and

Advanced System Buffering)

Available in versions that incorporate

256 KB Advanced Transfer Cache (on-die,

full speed Level 2 (L2) cache with Error

Correcting Code (ECC))

Dual Independent Bus (DIB) architecture:

Separate dedicated external System Bus and

dedicated internal high-speed cache bus

Internet Streaming SIMD Extensions for

enhanced video, sound and 3D performance

Binary compatible with applications running

on previous members of the Intel

microprocessor line

Dynamic execution micro architecture

Intel Processor Serial Number

Power Management capabilities

— System Management mode

— Multiple low-power states

Optimized for 32-bit applications running on

advanced 32-bit operating systems

Flip Chip Pin Grid Array (FC-PGA) packaging

technology; FC-PGA processors deliver high

performance with improved handling protection

and socketability

Integrated high performance 16 KB instruction

and 16 KB data, nonblocking, level one cache

256 KB Integrated Full Speed level two cache

allows for low latency on read/store operations

Double Quad Word Wide(256bit) cache data

bus provides extremely high throughput on

read/store operations.

8-way cache associativity provides improved

cache hit rate on reads/store operations.

Error-correcting code for System Bus data

Enables systems which are scaleable for up to

two processors

The Pentium

III

processor is designed for high-performance desktops and for workstations and servers.

It is binary compatible with previous Intel Architecture processors. The Pentium

III

processor provides

great performance for applications running on advanced operating systems such as Windows* 98,

Windows NT and UNIX*. This is achieved by integrating the best attributes of Intel processors—the

dynamic execution, Dual Independent Bus architecture plus Intel MMX™ technology and Internet

Streaming SIMD Extentions—bringing a new level of performance for systems buyers. The Pentium

III

processor is scaleable to two processors in a multiprocessor system and extends the power of the

Pentium II processor with performance headroom for business media, communication and internet

capabilities. Systems based on Pentium

III

processors also include the latest features to simplify system

management and lower the cost of ownership for large and small business environments. The Pentium

III

processor offers great performance for today’s and tomorrow’s applications
