No it is half as fast. Ghz (Giga Hertz) is the clock speed of the CPU, or the number of processes per second. 1.5Ghz means that a "pulse" is sent from the CPU 1.5 billion times per second, 3.0Ghz means that a pulse is sent out 3 billion times per second. Basically the higher the "Ghz" the better, however, watch out for Mhz or Khz, as they are only million pulses a second and thousand pulses a second respectively. Also note that there are other factors that are used to calculate the speed of a CPU, but the clock speed in Ghz is commonly accepted as the most important figure in CPU's.
No. The type of processor(s) you have will all run at 1.5
No. Memory is a way for the computer to store things so it can access them quickly. The processor is used to compute and crunch numbers to decide what to do. Having more memory or a faster processor are both good things, but they are completely different. A 3 ghz with one gig of ram would probably be the faster option.
Applications which have been designed to take advantage of mult-core processors will run about twice as fast on a quad core processor as compared to a dual core processor.
A dual core processor would only be able to do a certain number of tasks at any one time, while a quad core processor can do twice as many functions, and can do them twice as fast. These features relate to the speed and productivity of your computer.
Its not the fastest, but the AMD 64 processor is still fast.
This "3MB" is probably proceeded by "L2 cache" or "L3 cache" Or, its 3GHz. If it is 3MB, then it is referring to the instruction-caching memory that is built right into the processor, a few small panels of extremely fast memory that temporarily store instructions for the processor. The including of cache greatly increased a processors overall performance. The L2 and L3 portion refer to levels of cache. L1 Cache is very small, typically two blocks of 32KB or 64Kb. This Cache is the fastest, used for branch prediction and direct instruction strings. L2 Cache is larger, typically 1MB or 2MB, and also a fair deal slower than L1 cache. L3 Cache is the slowest, and is shared by multiple cores (If there is more than 1) and is the largest cache, typically 3MB - 16MB, depending on the processor. If it is actually 3GHz, then this is the number that reflects the number of Cycles Per Second, or Hertz, that the processor is capable of. 3Ghz is Three Giga-Hertz, or 3,000,000,000 Cycles per Second. Amazing isn't it?
That would be counter intuitive, buy a laptop with a fast processor in the first place.
Yes, because the computer with a 2.4 GHz dual core works nearly twice as fast than a 2.5 single core.
The CPU is also known as the processor. A processor is the major factor to consider in how fast a computer can process data.
Processor which make computer fast,efficient,and convinent for users.
A computer with a fast processor will work faster, but will not have a noticeable effect on your download speeds.
Both the processor, which allows the computer to do tasks, the better that is, the faster your computer can work the RAM which stores the things for the processor to process, the more you have the better. AND the hard drive, the faster this is, the faster the processor can grab information off it.
Gigahertz are a measurement of how fast a processor operates. They can be "upgraded" in the sense that you can overclock a processor to get "more" of them, or you can install a better processor for the same effect.
