【 Weak current College 】 [posted] tell you Duo not known of the five areas

Now everyone knows Duo. People mention it is multi-tasking, multi-threading. However, eating this bowl of hot meals, we have to calm down, don't. Small series is to introduce you to easily overlooked details, or easily misunderstood. Want to help.

1. either Intel or AMD is not the first company to launch dual-core processors.

In fact, as early as 2001, IBM introduced its first dual-core Power4 processor. IBM was used in its RISC server. While AMD and Intel in 2004 when we plan to launch dual-core processor, in 2005, they launched a dual-core processors respectively. AMD and the 2005 21 April officially launched the AMDOpteron processor (used with the server and workstation), AMD Athlon64X2 Duo (for home and business users). While Intel is in the 2005 11 April launched their Pentium processor.

2. dual-core processor by the technical side, is inevitable.

Single-core processors to achieve better performance with faster processing speed, you need greater capacity, more strong thermal conditions. In fact in 2005, Intel cancelled production 4.0GHz "Tejas" single-core processors. Because they found that frequency to achieve this, it's driving voltage must achieve 100W. Moreover, to ensure its normal operation should have a temperature control, you need a larger radiator. But people need and not with the increasing the voltage of methods to increase speed.

The duo will be the best answer. Dual-core performance will undoubtedly have a new single-core, rather than the processor. This is the British Cole and AMD Launches dual-core processor-the real reason.
3. the ratio is not a clock frequency, but the overall performance of the

If you think that the duo have the fastest clock frequency, it is mistaken. If you only focus on the processor clock frequency, so you can choose Intel Pentium4 processors, model 670, its clock frequency is 3.8GHz, Pentium4660, clock speed is 3.6GHz. In dual-core, mainstream PentiumD820, its clock frequency only 2.8GHz. Compare with solo in the fastest processor frequency.

But with the same frequency is 2.4GHz Athlon643400 + and dual core Athlon64X24600 + contrast. After testing, the duo's performance improves. Duo's overall performance is the solo 1.4 times to 1.8 times.

4. dual-core related aspects

After investigation of domestic users, 48% of PC users do not understand what is dual core. 42% of people who think they know that the dual-core, 10% of people think they know what a duo; 52% of the people know it technology; only 12% of the people understand that the dual-core system. Market researcher Frost and Sullivan found in desktop processors, notebook and server processor market, there will be 15% to 25% of single-core processing was replaced by a dual-core processor. Dual-core is not just a kernel, the power of control, it also includes the security considerations and application of virtual technology.

5. dual-core or walk the edge of the processor

In addition to the dual-core, now there are four hot topics. Intel has to 07 years of arrival, prepare their quad-core server. And AMD is also actively preparing for war. Vision and then farther, Intel's eight-core processor "Yorkfield" also plans to meet in 2008. It seems that more and more nuclear will welcome everyone. At that time dual-core or what you want?
