Computer cores have been increasing in speed, and increasingly quickly. Manufacturers were in a race to dispose of the chip with the fastest speed, measured in GHz. One surprise is that despite these increases in clock speed, the actual speed of programs did not increase proportionately.
Most laptops will function with Pentium M, Celeron or Core 2 processors. The latter is literally more superior. Next is to look at the clock speed. Generally the range is between one to three GHz and higher number indicates better speed. The clock speed is, in fact, the real speed of the processor. But these factors don’t work independently, as there may be circumstances where the Core 2 processor can perform better than the Celeron processor with a higher clock speed. Other factors that may influence the performance of a CPU processor are the Cache and Core count. The dual core processor is capable of doubling the clock speed so if you happen to buy the Core 2 Duo laptop with a 2.17 GHz clock speed, the real speed is actually 4.34 GHz. However, not all games or programs can support the dual-core so you need to look out for compatibility factor.
Dual core should be appropriate although the Quad Core processors are available but way pricier than the dual type, for those people who intend to upgrade processor for more power. Cache, on the other hand, acts as a buffer between your RAM and the processor. The faster your Cache is, your laptop will perform faster. In such economical times, price is said to be most prominent factor for all consumers. Do not be trapped by the high prices but always look for the most appropriate components for your laptop.
As modern programs make much heavier use of other computer parts like memory, and there are often many running at the same time, another approach was needed.
Continuing On With Dual-core Processor
By putting two ‘brain’ parts into the processor, you can run two programs on two cores, without first having to share it between them. The effect of this situation is that when running two or more programs, the processor can now handle much more as a whole.
Games rely on the brute strength of a powerful processor to help them along unlike the multitasking environment that is usual for a computer either at home either at the office. So far there’s no technology to capitalize on the two processors, like the capacity to split its tasks over two cores. Most gaming hasn’t improved with this new technology.
As with processors in the past the mainstream of dual core processors is dominated by the two big guys, Intel and AMD.
Intel offers two processors in its range, same processor, just different speeds. The lower priced of the Pentium D processors comes in at around $250. This price is reasonable considering how much you would pay for the upper part of the line single core processor.
You can find quad-core processors in computer that range in prices from $800 all the way into the thousands. This is because there are like in dual core processors different levels of speed on every processor. There are some quad-core processors that operate at 2.33GHz and others that are operating at 3.05GHz. The difference in speed of the two is only evident when your doing things like playing hard core gaming or doing intense video and picture editing.
The Pentium D is founded on the same core as it’s single core counterparts, just two of them inside. Its boost in performance is quite notable, and makes it presence felt in the multitasking environment.
The AMD Athlon X2 is AMD’s offering in the dual core market. Unlike the Pentium D its lowest priced model comes in at a staggering $400. It’s not expensive compared to processors like its FX series. These are over $1000, but in comparison to Intel it’s expensive.
It too relies on the same core as its single core cousins and also offers the same performance increases.
The price of the AMD is surprising. From a company that became famous for it’s low cost, high performance processors this is quite a blow. Even the upper model of the Pentium Ds comes in at less that AMD’s cheapest model.
The price might be justified if the AMD actually gave a significant performance boost. However, it doesn’t.
I think I would be ready to switch back to an Intel processor, for the very first time in a long time. Although my preference isn’t for dual core, if I had or needed to switch I would surely go straight for the Pentium D.
Considering how powerful processors have become I would still not make the switch. Dual core hasn’t been around long enough to produce low cost, slightly out of date models. The power of the AMD Athlon 64 3000+ more than does it for my computing needs. That’s where I would stay for now.
There are various models of Mac Pro, with single processor systems and dual processor systems enabling you to have from 4 to 12 cores of processing power to provide you with the most powerful Mac experience ever.
So for those who’re looking for the next cool thing for their desktop computer and price isn’t a huge issue, this would be your best choice, but go for the lower end Pentium D.
