Intel Pentium 4 Processor 3.2GHz, 800MHz FSB, Socket 478 512KB Cache with Fan and Heatsink
The Intel Pentium 4 processor is based on the Intel® NetBurst™ micro-architecture and includes several new performance enhancing features. Don't get behind with slow speeds! Upgrade your system with the powerful Intel Pentium4 3.2GHz processor with 800MHz Front Side Bus! The Pentium 4 processor supporting Hyper-Threading Technology*increases processor efficiency by executing more than one instruction thread at a time. This technology is designed to deliver superior performance with multi-threaded applications and in multi-tasking environments. A deeper pipeline enables instructions inside the processor to be queued and executed at a much faster rate, and allows the Pentium 4 processor to achieve the world's highest clock speeds for desktop PCs. Streaming SIMD Extensions 2 consists of 144 new instructions including SIMD double precision floating point, SIMD 128-bit integer, and new cache and memory management instructions. Streaming SIMD Extensions 2 enhances performance to accelerate video, speech, encryption, imaging, and the most demanding of Internet computing, and non-threaded workstation applications. Streaming SIMD Extensions 3 consists of 13 new instructions including 5 Complex Arithmetic evaluations, 2 Improved Load/Stores for improved performance, 4 Horizontal evaluations to improve speed of evaluations, and 2 Improved Hyper Threading instructions. Multiple system bus transfer rates that help speed the transfer of information from the processor to the rest of the system, improving throughput and performance. Also provides the user with the flexibility to take advantage of higher system memory bandwidth. Extends the Dynamic Execution features found in the previous generation P6 micro-architecture. Improved branch prediction accelerates the flow of work to the processor and helps overcome the deeper pipeline. Very deep out-of-order speculative execution carries out over 100 instructions speculatively, ensuring that the processor's superscalar execution units remain busy, improving overall execution. A 128-bit floating-point port and a second port for data movement enable smooth lifelike 3D and graphics. Advanced L1 instruction cache removes decoder pipeline latency, and caches "decoded" instructions, thus improving efficiency and hit rate to cached instructions. The 12 Kµop portion of the L1 cache supplies decoded instructions into the processor pipeline. There is also an 8 KB data portion of L1 cache. Integer Arithmetic Logic Unit (ALU) clocked at twice the core frequency provides four ALUs of computing bandwidth and allows lower latency execution increasing performance for certain integer operations.
