Which is better Intel Pentium 4 or Intel Pentium D?

Answer 1

The Pentium 4 is a seventh-generation x86 architecture microprocessor produced by Intel and is their first all-new CPU design, called the NetBurst architecture, since the Pentium Pro of 1995. Unlike the Pentium II, Pentium III, and various Celerons, the architecture owed little to the Pentium Pro/P6 design, and was new from the ground up. The microarchitecture of Netburst featured a very deep instruction pipeline, with the intention of scaling to very high frequencies. It also introduced the SSE2 instruction set for faster SIMD integer, and 64-bit floating-point computation.

The original Pentium 4, codenamed "Willamette", ran at 1.4 and 1.5 GHz and was released in November 2000 on the Socket 423 platform. Notable with the introduction of the Pentium 4 was the comparatively fast 400 MT/s FSB. It was actually based on a 100 MHz clock wave, but the bus was quad-pumped, meaning that the maximum transfer rate was four times that of a normal bus, so it was considered to run at 400 MT/s. The AMD Athlon was running at 266 MT/s (using a double-pumped bus) at that time.

As is traditional with Intel's flagship chips, the Pentium 4 also came in a low-end Celeron version (often referred to as Celeron 4) and a high-end Xeon version intended for SMP configurations.

The Pentium 4 line of processors was retired on July 27, 2006, replaced by the Intel Core 2 line, using the "Conroe" core.


The Pentium D is a series of microprocessors that was introduced by Intel at the Spring 2005 Intel Developer Forum. A 9xx-series Pentium D package contains two Pentium 4 Cedar Mill dies, unlike other multicore processors (including the Pentium D 8xx-series) that place both cores on a single die.

The Pentium D was the first announced multicore CPU (along with its more expensive twin, the Pentium Extreme Edition) from any manufacturer intended for desktop computers. Intel underscored the significance of this introduction by predicting that by the end of 2006 over 70% of its shipping desktop CPUs would be multicore. Analysts have speculated that the clock rate race between Intel and AMD is largely over, with no more exponential gains in clock rate looking likely. Instead, as long as Moore's Law holds up, it is expected that the increasing numbers of transistors that chip-makers can incorporate into their CPUs will be used to increase CPU throughput in other ways, such as by adding cores as the Pentium D does.

With the release of the Intel Core mobile processors and Intel Core 2 desktop processors, the Pentium D is the final processor to carry the Pentium brand name that has been at the forefront of Intel's products since 1993


So, i say Intel Pentium 4

Answer 2

Pentium 4 is a single core processor, and pentium D is a dual core processor that is 2 separate processors on the same chip.

Pentium 4 with Hyperthreading (HT)
HT technology only makes the most of the frequency by making the cpu a little smarter: when you execute a thread sometime there are poses when the cpu waits for info from the ram. Without HT technology the cpu would simply wait and do nothing while waiting but with HT the cpu notice that he is doing nothing or that thread so while he waits he executes other threads.
For e.g, A Pentium 4 Processor at 3.06GHZ with HT is a single processor running at 3.06GHZ. It can run 2 different threads at a combined speed of 3.06ghz. The processor splits clock cycles between the two different threads.

Pentium D
With the dual processors (cores), you'll experience overall smoother feeling computer operation, because the OS can direct a process to the least used processor, so even if one processor is busy scanning a file for viruses, the other processor can be doing something else.
For e.g, A Pentium D Processor 830 with Dual Core Technology (3.0GHz, 800FSB) is two seperate processors on the same chip both running @ 3.0GHZ. This processor can run 2 different threads at the same time. Each thread will run at a speed of 3.0GHZ.


Many applications themselves don't directly support using more than one processor (though PhotoShop and graphic application in general support,and there are others, and there will be even more in the future), but the OS knows how to use dual processor,so the computer can do twice as much processing at once (This doesn't mean everything will be twice as fast, just that multiple processes don't have to wait to use a single CPU).

Possibly the only heavy users of computer who might not benefit from dual processors (cores) are gamers who only play games that are not dual-processor aware, and have everything else turned off on their computers.

Answer 3

a pentium D is a single middle processor, in different words it has one CPU. a center 2 has 2-4 CPUs observing the type. it could have a decrease clock velocity, yet because of the variety of cores, it is going to consume the lunch of any pentium. even a twin middle one million.66GHz is greater perfect than the pentium D. that is relating to the comparable in clock velocity, inspite of the undeniable fact that it may handle two times as plenty artwork on the comparable time. remember the expression "what you pay for is what you get" and you are able to count style the variety of cores first , clock velocity 2nd. that way you will get a greater perfect theory of a proc's overall performance
