Core 2 quad vs dual core?

Answer 1

Dual cores have two cores, and Quad cores have four. All the cores are on the same chip they share the same memory and data path to the motherboard.

A Dual core processor is basically 2 processors in 1, with some loss.

A Quad core is 2 Dual core processors in 1 ,so a Quad core would be twice as fast as a Dual core, while a Dual core is twice as fast as a single core.

Answer 2

I'm a big fan of dual-core systems. I think there's a clear and substantial benefit for all computer users when there are two CPUs waiting to service requests, instead of just one. If nothing else, it lets you gracefully terminate an application that has gone haywire, consuming all available CPU time. It's like having a backup CPU in reserve, waiting to jump in and assist as necessary. But for most software, you hit a point of diminishing returns very rapidly after two cores. In Quad-Core Desktops and Diminishing Returns, I questioned how effectively today's software can really use even four CPU cores, much less the inevitable eight and sixteen CPU cores we'll see a few years from now.

To get a sense of what kind of performance improvement we can expect going from 2 to 4 CPU cores, let's focus on the Core 2 Duo E6600 and Core 2 Quad Q6600 processors. These 2.4 GHz CPUs are identical in every respect, except for the number of cores they bring to the table. In a recent review, Scott Wasson at the always-thorough Tech Report presented a slew of benchmarks that included both of these processors. Here's a quick visual summary of how much you can expect performance to improve when upgrading from 2 to 4 CPU cores

Answer 3

Dual quad core means that there are two quad-core CPUs in the system, bringing the total number of cores to eight. A dual core CPU is simply a CPU that has two independent processing units inside.

Answer 4

The main difference between the two types of processors is the computing power available in both. The quad core involves more "pathways" that allow multiple strands of information to flow simeltaneously, while the dual core has 2 paths the quad has 4, this not only is 2 as powerful but actually a factor more efficient. The price diffence is notable as quad core is a noticable upgrade from dual core, but the performance increase is worth the price increase.

Answer 5

Quad is better because dual is 2 cores and quad is 4 cores.

Answer 6

All other factors being equal, a quad-core will provide for better performance (as measured by operations per second) than a dual core.

Answer 7

Intel Core 2 Quad is an Intel processor with four processing cores in it. Dual core is the property of having two cores in one CPU.
