What is the main Difference between Pentium 4 and Dual core processor?

Answer 1

Depends on which "dual-core" processor you're talking about.

The Pentium D dual-core is basically two Pentium 4 cores on one chip. It's not quite twice the processing power of one Pentium 4, because each core is running at a lower frequency than the fastest single cores out there. Also, each core has to "share" the frontside bus for communication to main memory and other components on the motherboard. Plus, unlike higher-end AMD Opterons, they have to share that same bus for cross-communication between CPU cores. The bus is heavily overloaded.

But in the end, they're great for multitasking, which is where you notice the benefit. If you benchmark the speed of just one application, there will hardly be a difference between a single and dual-core. But when you start talking about several apps running at once (such as burning a DVD and playing a game), dual-cores really start to shine.

The newest from Intel is the Core 2 Duo which is a whole new processor altogether. It blows away the fastest Pentium D's and Pentium 4's.

Answer 2

Pentium 4 processors are high speed and have a single core that is used to perform all processing functions whereas a Dual Core processor uses two cores. each core has a slightly slower speed than that of a Pentium 4, but since the Dual Core Processor has two cores, the two are combined to make an Overall speed. the dual core is supposedly more efficient when multitasking.

Answer 3

Well, "dual core" processor really refers to a class of processors. You're probably thinking of the Intel Core Duo/Core 2 Duo. Anyways, the quick answer is that a dual core processor is kind of like having 2 pentiums hooked together on one chip. (In fact, Intel did exactly this for awhile as an interim solution during their development cycle, before integrating the two more tightly). It allows you to run multiple programs at once, but feel dramatically less lag (you know how those stupid Norton Antivirus tools hammer some systems). As well, certain kind of programs are smart enough to use both cores at once and, in some cases, work twice as fast.

Answer 4

the dual middle processor is a mixture of two self reliant processors and their distinct caches and cache controllers are equipped onto a unmarried silicon chip. it truly is built-in at the same time. the dual middle is to manage multi-pastime inspite of the undeniable fact that it varieties like 2 layers of processing time. it truly is nearly a stacking approach and procedure. The Hyperthreading is a diverse technologies. it truly is a unmarried self reliant processor which could multi-pastime the artwork load like driving right into a street the position the line will chop up aside and connect back after some metres. As such it signifies that it would want to settle for most request and procedure it concurrently and output each and each of the request by skill of exiting the same way. the Hyperthreading is like run parrallel throughout the time of the request procedure. for further theory on it, you may visit the decrease than link.

Answer 5

Speed, dual core is usualy faster than single core processors like the P4 even though the Ghz may be lower.

Answer 6

Dual core processors have two logic brains on the same dye, so they can process more "threads" at a time.
