What is difference between intel 4 & intel core dual ?explain briefly.?

Question

Actualy i want comparisons and advantage & disadvantage of both intel pc

Answer 1

if you are using pc at home, there is no problem using only intel P4. but if you are with a more comprehensive programs that needs more space, ex. editing a video while downloading music...dual core is apt.

Pentium 4 (with 1 single-core die) was superseded by the Pentium D (64bit processor, comprised with two single-core dies [NetBurst microarchitecture] in one package) and Pentium Extreme Edition brands of dual-core CPUs. The core-duo or dual core pentium had both cores placed on each dual-core die (Core architecture) with a reduced power consumption.

A dual-core device contains two independent microprocessors and a quad-core device contains four microprocessors. A multi-core microprocessor implements multiprocessing in a single physical package.

A dual-core processor is like a four-lane highway—handling up to twice as many cars as its two-lane predecessor without making each car drive twice as fast. Similarly, with an Intel dual-core processor-based PC, you can perform multiple tasks such as downloading music and gaming simultaneously.

If you are performance conscious, go for Core Duo. If you are budget conscious, then Pentium 4 or Pentium D is quite ok...just add mem stick and improve your video care using PCI vcards instead of AGP vcards...with the same bit, the latter runs slower.

Answer 2

There's not really any. A dual core is a CPU (Central Processing Unit) wit two cores. Core 2 Duo is the Intel brand name for their dual core Processors. Same for Core 2 Quad and quad core. Quad core is a cpu that has 4 cores, Core 2 Quad is the model or brand name of Intel CPU's with 4 cores.

Answer 3

Intel Pentium 4 is of different architecture vs Core Duo. Also Core Duo has 2 processors in its central core and hence considered to be much faster. But the Windows and other programs doesn't seem to take FULL advantage of this dual processors features.

Answer 4

The Core 2 brand refers to a range of Intel's mobile and desktop 64-bit dual-/quad-core x86 CPUs with the Core microarchitecture, which evolved from the 32-bit dual-core Yonah mobile processor. The Yonah comprised two interconnected cores - each derived from the Pentium M branded single-core microprocessor - coupled as a single die IC. The Core 2 marked a relegation of the Intel's Pentium brand to a lower-end market, and a reunification of Intel's notebook and desktop brand names, previously divided into the Pentium M and Pentium 4 lines.

The Core 2 brand was launched on July 27, 2006, comprising ''Duo'' (dual-core), Quad (quad-core), and Extreme (dual- or quad-core CPUs with higher speeds and unlocked multiplier) branches. The brand covers processors based on various cores; "Conroe" and "Allendale" (dual-core for higher- and lower-end desktop use, respectively), "Merom" (dual-core for notebooks), "Kentsfield" (quad-core for desktops), and their variants named "Penryn" (dual-core for notebooks), "Wolfdale" (dual-core for desktops) and "Yorkfield" (quad-core for desktops). Although the "Woodcrest", "Clovertown" and the upcoming "Tigerton" core CPUs for servers and workstations are also based on Core architecture, they are marketed under the Xeon brand[1]. The first Core 2 Duo processors were fabricated on 300 mm wafers using a 65 nm manufacturing process.

Unlike the NetBurst architecture of Pentium 4 or Pentium D branded processors, the Core architecture does not stress extremely high clock speeds, but rather improvements in the processor's usage of both available clock cycles and power. This translated into more efficient decoding stages, execution units, caches, and buses, etc, reducing the Core 2 CPU's power consumption, while enhancing their processing capacity. With a TDP of up to only 65 W, the Core 2 dual-core Conroe consumed only half the power of some of the higher end dual-core Pentium D desktop chips[2] with a TDP of up to 130 W[3] (a high TDP requires many noisy cooling fans or a more expensive noiseless cooling system) and was more capable compared to them.

Intel Core 2 processors featured Intel 64 (also known as EM64T), Virtualization Technology (except T5500 or lower end E4x00), Execute Disable Bit, and SSE3. Core 2 also introduced SSSE3, Trusted Execution Technology, Enhanced SpeedStep, and Active Management Technology (iAMT2).

Typically for CPUs, the Core 2 Duo E4000/E6000, Core 2 Quad Q6600, Core 2 Extreme QX6800, QX6700 and QX6800 CPUs were affected by bugs, but apparently minor[4].

Answer 5

The main difference is that the Core Duo effectively has two CPUs on a single chip. So you effectively get double the speed it claims to have (and its more power efficient).

Answer 6

Intel pentium 4 has one processor
Core Duo has two
Core 2 Duo has four

gives more power obviously and somehow it uses less energy
