Intel Pentium 4 Processors

The Pentium 4 was introduced in November 2000 and represented a new generation in processors (see Figure 3.27). If this one had a number instead of a name, it might be called the 786 because it represents a generation beyond the previous 686 class processors. Several variations on the Pentium 4 have been released, based on the processor die and architecture. Several of the processor dies are shown in Figure 3.28.

Figure 3.27. Pentium 4 FC-PGA2 processor.

Figure 3.28. The CPU dies for the Pentium 4 CPU based on the Willamette, Northwood, and Prescott cores.


The main technical details for the Pentium 4 include the following:

  • Speeds ranging from 1.3GHz to 3.8GHz.

  • Software compatible with previous Intel 32-bit processors.

  • Some versions supporting EM64T (64-bit extensions) and Execute Disable Bit (buffer overflow protection).

  • Processor (front side) bus that runs at 400MHz, 533MHz, 800MHz, or 1,066MHz.

  • Arithmetic logic units (ALUs) that run at twice the processor core frequency.

  • Hyper-pipelined (20-stage or 31-stage) technology.

  • HT Technology support in all 2.4GHz and faster processors running an 800MHz bus and all 3.06GHz and faster processors running a 533MHz bus.

  • Deep out-of-order instruction execution.

  • Enhanced branch prediction.

  • 8KB or 16KB L1 cache plus 12K micro-op execution trace cache.

  • 256KB, 512KB, 1MB, or 2MB of on-die, full-core speed 256-bit-wide L2 cache with eight-way associativity.

  • L2 cache that can handle all physical memory and supports ECC.

  • 2MB of on-die, full-speed L3 cache (Extreme Edition).

  • SSE2-SSE plus 144 new instructions for graphics and sound processing (Willamette and Northwood).

  • SSE3-SSE2 plus 13 new instructions for graphics and sound processing (Prescott).

  • Enhanced floating-point unit.

  • Multiple low-power states.

Intel abandoned Roman numerals for a standard Arabic numeral 4 designation to identify the Pentium 4. Internally, the Pentium 4 introduces a new architecture that Intel calls NetBurst microarchitecture, which is a marketing term and not a technical term. Intel uses NetBurst to describe hyper-pipelined technology, a rapid execution engine, a high-speed (400MHz, 533MHz, 800MHz, or 1,066MHz) system bus, and an execution trace cache. The hyper-pipelined technology doubles or triples the instruction pipeline depth compared to the Pentium III (or Athlon/Athlon 64), meaning more and smaller steps are required to execute instructions. Even though this might seem less efficient, it enables much higher clock speeds to be more easily attained. The rapid execution engine enables the two integer ALUs to run at twice the processor core frequency, which means instructions can execute in half a clock cycle. The 400MHz/533MHz/800MHz/1,066MHz system bus is a quad-pumped bus running off a 100MHz/133MHz/200MHz/266MHz system clock transferring data four times per clock cycle. The execution trace cache is a high-performance Level 1 cache that stores approximately 12K decoded micro-operations. This removes the instruction decoder from the main execution pipeline, increasing performance.

Of these, the high-speed processor bus is most notable. Technically speaking, the processor bus is a 100MHz, 133MHz, 200MHz, or 266MHz quad-pumped bus that transfers four times per cycle (4x), for a 400MHz, 533MHz, 800MHz, or 1,066MHz effective rate. Because the bus is 64 bits (8 bytes) wide, this results in a throughput rate of 3,200MBps, 4,266MBps, 6,400MBps, or 8,533MBps.

In the Pentium 4’s 20-stage or 31-stage pipelined internal architecture, individual instructions are broken down into many more substages than with previous processors such as the Pentium III, 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. Another important architectural advantage is HT Technology, which can be found in all Pentium 4 2.4GHz and faster processors running an 800MHz bus and all 3.06GHz and faster processors running a 533MHz bus. HT enables a single processor to run two threads simultaneously, thereby acting as if it were two processors instead of one. For more information on HT Technology, see the section “HT Technology,” earlier in this chapter.

The Pentium 4 initially used Socket 423, which has 423 pins in a 39×39 SPGA arrangement. Later versions used Socket 478; the final versions use Socket T (LGA775), which has additional pins to support new features such as EM64T (64-bit extensions), Execute Disable Bit (protection against buffer overflow attacks), Intel Virtualization Technology, and other advanced features. The Celeron was never designed to work in Socket 423, but Celeron and Celeron D versions are available for Socket 478 and Socket T (LGA775), allowing for lower-cost systems compatible with the Pentium 4. Voltage selection is made via an automatic voltage regulator module installed on the motherboard and wired to the socket.

Table 3.15 includes a guide to Pentium 4 processor features as well as those for the Pentium 4 Extreme Edition, which is discussed in more detail in the next section. For information on the features unique to a specific processor, see the Intel Product Information website at http://ark.intel.com/Default.aspx.

For some time now, it has been obvious that “Pentium 4” has been far more of a brand than a single processor family, leading to endless confusion when evaluating existing systems for their suitability for a particular task. Because of the three form factors (Socket 423, Socket 478, and Socket 775) and the range of features available in the Pentium 4 family, it’s essential that you determine exactly what the features are of a particular processor in a system if you need to match the system to a particular performance level.

Pentium 4 Extreme Edition

In November 2003, Intel introduced the Extreme Edition of the Pentium 4, which is notable for being the first desktop PC processor to incorporate L3 cache. The Extreme Edition (or Pentium 4EE) is basically a revamped version of the Prestonia core Xeon workstation/server processor, which has used L3 cache since November 2002. The Pentium 4EE has 512KB of L2 cache and 2MB of L3 cache, which increases the transistor count to 178 million transistors and makes the die significantly larger than the standard Pentium 4. Because of the large die based on the 130-nanometer process, this chip was-expensive to produce, and the extremely high selling price reflects that. The Extreme Edition was targeted toward the gaming market, where people are willing to spend extra money for additional performance. The additional cache doesn’t help standard business applications as well as it helps power-hungry 3D games.

In 2004, revised versions of the Pentium 4 Extreme Edition were introduced. These processors are based on the 90-nanometer (0.09-micron) Pentium 4 Prescott core but with a larger 2MB L2 cache in place of the 512KB L2 cache design used by the standard Prescott-core Pentium 4. Pentium 4 Extreme Edition processors based on the Prescott core do not have L3 cache.

The Pentium 4 Extreme Edition was produced in both Socket 478 and Socket T form factors, with clock speeds ranging from 3.2GHz to 3.4GHz (Socket 478) and from 3.4GHz to 3.73GHz (Socket T).

Pentium 4 Power Supply and Cooling Issues

Compared to older processors, the Pentium 4 requires a lot of electrical power. Because of this, starting in February 2000, Intel changed the ATX motherboard and power supply specifications to support a CPU voltage regulator module powered from 12V instead of 3.3V or 5V, as with previous designs. By using the 12V power, more 3.3V and 5V power is available to run the rest of the system, and the overall current draw is greatly reduced with the higher voltage as a source. PC power supplies normally generate more than enough 12V power, but the previous ATX motherboard and power supply designs originally allotted only one pin for 12V power (each pin is rated for only 6 amps), so additional 12V lines were necessary to carry this power to the motherboard.

The fix appears in the form of a CPU power connector called the ATX12V connector. Any motherboard having the ATX12V connector requires that you supply power to it. If you are using an older ATX power supply that lacks the proper ATX12V connector, several companies sell adapters that convert a standard Molex-type peripheral power connector to the ATX12V connector. Typically, a 300-watt (the minimum recommended) or larger power supply has more than adequate levels of 12V power for both the drives and the ATX12V connector.

If your power supply is less than the 300-watt minimum recommended, you may need to purchase a replacement supply.

Cooling a high-wattage processor such as the Pentium 4 requires a large active heatsink. These heavy (sometimes more than 1 lb.) heatsinks can damage a CPU or destroy a motherboard when subjected to vibration or shock, especially during shipping. To solve this problem with Pentium 4 motherboards, various methods have been used to secure the heatsink in the system. Intel’s specifications for Socket 423 added four standoffs to the ATX chassis design flanking the Socket 423 to support the heatsink retention brackets. These standoffs enabled the chassis to support the weight of the heatsink instead of depending on the motherboard, as with older designs. Vendors also used other means to reinforce the CPU location without requiring a direct chassis attachment. For example, Asus’s P4T motherboard was supplied with a metal reinforcing plate to enable off-the-shelf ATX cases to work with the motherboard.

Socket 478 systems do not require special standoffs or reinforcement plates; instead, they use a scheme in which the CPU heatsink attaches directly to the motherboard rather than to the CPU socket or chassis. You can install motherboards with Socket 478 into any ATX chassis; no special standoffs are required.

Socket T (LGA775) systems use a four-side frame locking mechanism that holds the processor in place. The heatsink is positioned over the processor, and locking pins attach it to the motherboard. Later LGA sockets use a similar design.

Because the Pentium 4 processor family has been manufactured in three socket types with a wide variation in clock speed and power dissipation, it’s essential that you choose a heatsink made specifically for the processor form factor and speed you own.

Intel Pentium D and Pentium Extreme Edition

Intel introduced its first dual-core processors, the Pentium Extreme Edition and Pentium D, in May 2005. Although these processors used the code name Smithfield before their introductions, they are based on the Pentium 4 Prescott core. In fact, to bring dual-core processors to market as quickly as possible, Intel used two Prescott cores in each Pentium D or Pentium Extreme Edition processor. Each core communicates with the other via th MCH (North Bridge) chip on the motherboard (see Figure 3.29).

Figure 3.29. The Pentium D and Pentium Extreme Edition’s processor cores communicate with each other via the chipset’s MCH (North Bridge) chip.


For this reason, you cannot use Intel 915 and 925 chipsets and some third-party chipsets made for the Pentium 4 with the Pentium D or Pentium Extreme Edition. Intel’s 945 series, 955X, and 975X desktop chipsets, and the E7230 workstation chipset, are the first Intel chipsets to support these processors. The nForce 4 series from NVIDIA also works with these processors

Following are the major features of the Pentium D:

  • Clock speeds of 2.66GHz–3.6GHz

  • 533MHz or 800MHz processor bus

  • EM64T 64-bit extensions

  • Execute Disable Bit support

  • 65- or 90-nanometer manufacturing process

  • 2MB/4MB L2 cache (1MB/2MB per core)

  • Socket T (LGA775)

The 830, 840, and 9xx models also include Enhanced Intel Speed Step Technology, which results in cooler and quieter PC operation by providing a wide range of processor speeds in response to workload and thermal issues.

The Pentium Extreme Edition is a high-end version of the Pentium D, but with the following differences:

  • HT Technology is supported, enabling each core to simulate two processor cores for even better performance with multithreaded applications.

  • Enhanced Intel Speed Step Technology is not supported.

  • It includes unlocked clock multipliers, enabling easy overclocking.

Table 3.16 compares the features of the various Pentium D and Pentium Extreme Edition processors.
