Based upon Intel's leading 0.13 micron and 0.18 micron manufacturing process 
technologies. 0.13 micron process with speeds from 1.80A GHz to 2.80 GHz and 
0.18 micron process with speeds 1.70 GHz to 1.90 GHz.  

  

 
The Pentium 4 processor at 1.70, 1.80, 1.80A, 1.90, 2A, 2.20, 2.26, 2.40, 2.40B, 2.50, 2.53, 
2.60, 2.66 and 2.80 GHz is designed for desktop PCs, as well as for entry-level workstations. 
The processor is binary-compatible with previous generation Intel Architecture processors.  
 

  

 
Intel NetBurst microarchitecture delivers a number of innovative features including hyper-
pipelined technology, 533-MHz or 400-MHz system bus, Execution Trace Cache, and Rapid 
Execution Engine, as well as a number of enhanced features such as Advanced Transfer 
Cache, Advanced Dynamic Execution, enhanced floating-point and multimedia unit, and 
Streaming SIMD Extensions 2 (SSE2). Many of these innovations and advances were made 
possible with improvements in processor technology, process technology, and circuit design 
and could not previously be implemented in high-volume, manufacturable solutions. The 
features and resulting benefits of the microarchitecture are defined below.  
 

 
The hyper-pipelined technology of the Intel NetBurst microarchitecture doubles the pipeline 
depth compared to the P6 microarchitecture used on today's Pentium III processors. One of 
the key pipelines, the branch prediction / recovery pipeline, is implemented in 20 stages in the 
Intel NetBurst microarchitecture, compared to 10 stages in the P6 microarchitecture. This 
technology significantly increases the performance, frequency, and scalability of the  
processor.  
 

  

 
The Pentium 4 processor's 533-MHz system bus supports Intel's highest performance 
desktop processor by delivering 4.2 GB of data-per-second into and out of the processor. This 
is accomplished through a physical signaling scheme of quad pumping the data transfers over 
a 133-MHz clocked system bus and a buffering scheme allowing for sustained 533-MHz data 
transfers. The Pentium 4 processor's 400-MHz system bus supports Intel's performance 
desktop processor by delivering 3.2 GB of data-per-second into and out of the processor. This 
is accomplished through a physical signaling scheme of quad pumping the data transfers over 
a 100-MHz clocked system bus and a buffering scheme allowing for sustained 400-MHz data 
transfers. This compares to 1.06 GB/s delivered on the Pentium III processor's 133-MHz 
system bus.
