Intel Pentium 4 530 3.0GHz Processor Features

Intel’s Advanced, Powerful Processor for Desktop PCs and Entry-Level Workstations
The Pentium 4 processor Extreme Edition at up to 3.40 GHz and the Pentium 4 processors from 3.60 to 2.40 GHz are designed for desktop PCs, as well as for entry-level workstations. These processors are binary-compatible with previous generation Intel architecture-based processors.
Intel NetBurst® Microarchitecture
Intel NetBurst microarchitecture delivers a number of innovative features including Hyper-Threading Technology, hyper-pipelined technology, 800, 533 or 400 MHz system bus, and Execution Trace Cache, 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). Further enhancements in the next generation 90 nm process-based Pentium 4 processor include Streaming SIMD Extensions 3 (SSE3). 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.
Hyper-Threading Technology
Hyper-Threading Technology (HT Technology) is ground-breaking technology that changes the landscape of processor design by going beyond GHz to improve processor performance. It allows software programs to "see" two processors and work more efficiently. This new technology enables the processor to execute two series, or threads, of instructions at the same time, thereby improving performance and system responsiveness. The Pentium 4 processor supporting HT Technology is designed specially to deliver immediate increases in performance and system responsiveness with existing applications in multitasking environments (that is, where two or more functions are running at the same time) and with many stand-alone applications today. Furthermore, the Pentium 4 processor supporting HT Technology provides performance headroom for the future.
Hyper-Pipelined Technology
The hyper-pipelined technology of the Intel NetBurst microarchitecture increases the pipeline depth delivering increased performance, frequency, and scalability of the processor. One of the key pipelines, the branch prediction/recovery pipeline, is implemented in 31 stages on the 90 nm Pentium 4 processor, compared to 20 stages on the 0.13 micron Pentium 4 processor.
800 MHz, 533 MHz or 400 MHz System Bus
In the Pentium 4 processor with 800 MHz system bus, the bus supports high performance by delivering up to 6.4 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 200 MHz clocked system bus and a buffering scheme allowing for sustained 800 MHz data transfers. The same quad-pumping of data is true for Pentium 4 processors with 533 MHz system bus (4.2 GB data-per-second with a 133 MHz clocked system bus) and Pentium 4 processors with 400 MHz system bus (3.2 GB data-per-second with a 100 MHz clocked system bus). This compares to 1.06 GB/s delivered on the Pentium® III processor's 133 MHz system bus.
Level 1 Execution Trace Cache
The 90 nm Pentium 4 processor features 16-KB data cache compared to 8-KB on the 0.13 micron Pentium 4 processor. In addition to the data cache, the Pentium 4 processor includes an Execution Trace Cache that stores up to 12-K decoded micro-ops in the order of program execution. This increases performance by removing the decoder from the main execution loop and makes more efficient usage of the cache storage space since instructions that are branched around are not stored. The result is a means to deliver a high volume of instructions to the processor's execution units and a reduction in the overall time required to recover from branches that have been mis-predicted.
