Since Intel introduced the Pentium 4 Processor a year ago (Nov. 20, 2000), the Pentium 4 has increased in clock speed for over 40% (600MHz). The Pentium 4 processor claims to deliver a new generation of performance for processing video and audio, exploiting modern Internet technologies, and displaying 3-D graphics.
Presenting you Intel's fastest processor, the Pentium 4 2.0GHz processor is the first microprocessor offering x86 CPU clocked at 2.0GHz. It is designed to meet the needs of today's most demanding computer user, the extreme user. However, the Pentium 4 2GHz surrounds no architectural improvements to the Pentium 4 core.
The Pentium 4's foundation is the Intel NetBurst micro-architecture, a collection of unique technologies that is powering Intel's most advanced 32-bit processors. The Pentium 4 processor with Intel NetBurst technology is the first completely new desktop processor design from Intel since the Pentium Pro processor, with its P6 micro-architecture, was introduced in 1995. The Intel Inside Logo
Highlights include Hyper Pipelined Technology, which enables the Pentium 4 processor to execute software instructions in a 20-stage pipeline, as compared to the 10-stage pipeline of the Pentium III processor. The 20-stage pipeline performs less work per clock cycle in exchange for higher clock speeds is the main reason the Pentium 4 has scaled this high so quickly. When built on the same manufacturing process, the Pentium 4 can scale to a higher clock speed much easier than its predecessor.
In the 20-stage pipelined internal architecture, individual instructions are broken down into many more sub-stages, making this almost like a RISC processor. Unfortunately, this can add to the number of cycles taken to execute instructions if they are not optimized for this processor. Early benchmarks running existing software showed that existing Pentium 3 or AMD Athlon processors could easily keep pace with or even exceed the Pentium 4 in specific tasks; however, this is changing now that applications are being recompiled to work smoothly with the Pentium 4's deep pipelined architecture.
In another word, the NetBurst technology allows the Pentium 4 core to beat away at higher clock speeds, while its greater pipeline depth (double that of the Pentium 3 and Pentium Pro P6 core), known as the hyper-pipelined technology, boosts the processor's frequency and scalability.
The Intel Pentium 4 2GHz CPU uses a 20.0x multiplier to run at its 2.0GHz frequency. The Pentium 4’s FSB is quad-pumped meaning that although data is transferred four times per clock, the true operating frequency of the bus is still 100MHz while offering data transfers equivalent to that of a 400MHz bus.
The first thing you will notice on the Intel Pentium 4 2.0GHz processor is the new socket interface and form factor.
The original Pentium 4 uses the 423-pin PGA socket interface while the new Pentium 4 uses the new 478-pin PGA socket interface. The launch of the Pentium 4 2.0GHz also introduced us to another new form factor for motherboards as well, the Socket-478.
The new 478-pin processors are also much smaller than the 423-pin predecessors.
The new socket features a much more densely packed arrangement of pins known as a micro Pin Grid Array (µPGA) interface. This allows the CPU to be much smaller and the space occupied by the interface socket on the motherboard to decrease as well. The new microPGA interface will cut manufacturing costs too.
We can also see a new type of heat sink fan for the 478-pin Pentium 4. What we mean is the new retention mechanism used to mount the heat sink has changed. Sure, we like the new retention mechanism pretty much. Installing the heat sink is much easier now compared to the older version of Pentium 4s and Pentium 3s. Mounting the heatsink and taking the heatsink out is simply by securing and unsecuring the clips on the cooler. Different heatsinks uses different type of retention mechanism. We received a few Pentium 4 coolers from AVC, Glacial Tech, and Evercool and we found out that all of them use completely different type of clips to secure the cooler into place. Intel's system came with a reference design heat sink fan - and it's really quiet. The entire system is extremely quiet too compared to my personal Athlon 1.4GHz system. Going back to 1.4GHz and living together with this system is really annoying!
Cooling this high wattage mini monster requires a large active heatsink. These heavy heatsinks can damage a CPU or destroy a motherboard when subjected to vibration or shock, especially during shipping. To prevent this, Intel's specifications for the Pentium 4 add four standoffs to the ATX chassis design flanking the Socket 423 to support the heatsink retention brackets. These standoffs enable the chassis to support the weight of the heatsink instead of depending on the motherboard, as with older designs.
Talking about the heat, we can monitor the core temperature of Intel's processor using hardware or software. The technology developed at Intel can change the processor usage to reduce the temperature if an overheat occurs. This is a really great technology. A video done by Tom's Hardware recently shown what happens when we take the heatsink off a processor running Quake 3. The Pentium 4 2.0GHz and the Pentium 3 both survived running the Quake 3 timedemo, by just slowing down but the temperature remains stable. Comparing it to the Athlons, a few seconds after removing the heatsinks, both processor started to smoke and the temperature is at a crazy 700 Celsius!
Almost every Pentium 4 processor is now available at 478-pin and we can see many motherboards supporting the new interface too. If you are planning to upgrade to a Pentium 4 processor, please make sure that you are purchasing the 478-pin CPU. In case you will want to upgrade your processor again in the near future, you can still upgrade to the upcoming Northwood Pentium 4 which uses the Socket-478 pin too.

ntel's upcoming processor, code-named Northwood, will be manufactured using the new Socket-478 pin interface. To make things easier for end-user, Intel has begun the production of Willamette Pentium 4 CPUs utilizing the new 478-pin interface. Intel already stop manufacturing the 423-pin processors and soon, we won't see any socket-423 pin processors anymore.
Code-named Northwood, the new, upcoming Pentium 4 chip which will be available anytime now, will be made using a .13-micron process instead of the current .18-micron process on the Pentium 4 2.0Ghz. It should launch at speeds faster than 2.3GHz. Some analysts predict that Intel will double the chip's on-die secondary cache from 256KB to 512KB (as it has already done with the new mobile Pentium III-M), which could translate into a nice performance boost.
The .13-micron manufacturing process will decrease the manufacturing cost of the Pentium 4 and enable cooler operation. The cost savings won’t directly be transferred to the end user as the 2.3GHz Northwood is expected to debut at close to $550 in 1,000 unit quantities.
About 0.13-micron technology
0.13 micron is a manufacturing term that refers to the feature size of the poly-silicon gate in the microprocessor. This feature size has a direct correlation to the speed and power requirements of the microprocessor. As feature sizes are reduced, the process speed (MHz) increases while the power requirements decrease correspondingly. 0.13 micron is currently the smallest feature size available in high volume manufacturing. This technology allows for greater speeds than ever before with lower power consumption, resulting in greater performance and longer battery life in thinner, lighter notebooks.
