In my previous article, I mentioned how Intel Atom processor is fueling the growth of Netbooks. Atom processors are used in a number of variants that are in a few families of devices, depending on the available resources on the processor, clock speed, whether multi-threading support, etc. divided
Current versions: The atomic isotopes, or the current versions of the Atom processor are 200 family, 300 family, N270 series and Z5xxProcessors. A large percentage of netbooks have switched their nuclear options. That is, has become as ubiquitous. What makes them so attractive! We will use a quick look here at the features of these processors. According to Intel, there is no special significance to the numbers assigned to these components, performance or otherwise. For example, the Z5xx family members are not necessarily a higher performance, faster devices, the 200-family. There are several featuresif these families, and what we quickly verify here. Ideal way would be to do it, you a matrix of the isotopes vs. features. However, the format of this article is not quite so suitable for a table. We will try our best to highlight the differences anyway. The processor components available, are so far, Z540, Z530, Z520, Z510, Z500, N270, 330 and 230 Newest member to join the team is the N280. The main functions look like asfollows. The format used is the number of processor clock speed, L1 cache size, follow FSB speed and maximum TDP rating. Clock speed in GHz is a simple element. You are on the 1.6-GHz mark except Z540 and N280, which are faster at 1.86 and 1.66 GHz respectively. Z500 has the slowest clock speed of 800MHz.
Z540: 1.86 GHz, 512KB, 533 MHz, 2.4 W
Z530: 1.60 GHz, 512KB, 533 MHz, 2.0 W
Z520: 1.30 GHz, 512KB, 533 MHz, 2.0 W
Z510: 1.10 GHz, 512 KB, 400MHz, 2.0 W
Z500: 0.8 GHz, 512KB, 400 MHz, 0.63 W
N280: 1.66GHz, 512KB, 667 MHz, 2.5 W
N270: 1.60 GHz, 512KB, 533 MHz, 2.5 W
330: 1.60 GHz, 1000 KB, 533 MHz, 8.0 W
230: 1.60 GHz, 512KB, 533 MHz, 4.0 W
The cache size specification is that the first level or the so called L1. This is fairly evenly among the members with the exception of the 330 that has a 1 MB of L1 cache. The clock speed indicates an expansion of raw processor speeds from 800 MHz to 1.86GHz. This is a great area. The L1 cache data are almost identical with the exception of the 330 that a small advantage over similar processor clock speed when it really should show sequential programs are involved. FSB (Front Side Bus) is the interface to the chip-memory system. The memory system here is the main memory or system memory, since they are called in different. This is a specification that will largely determine the system performance.
Even if the on-chip processor is reallyfast FSB speed actually determines how fast is the complete system on an average. N280 can handle fastest interface at 667 MHz, while the Z510 and Z500 only 400 MHz can process transactions. Other components operate at 533 MHz. Unique thing about the N280 is that it can handle HD video, with the chipset GN40 it can go up to 1080p video-link. What is really interesting about these processors is their extremely low power operation. TDP, thermal design power, is a specification formaximum power in the chip design into consideration for the thermal design should be taken. Except for 330 and 230 are the ratings at 2.5 watts levels. The lowest power consumption to Z500. There are other features in the processors in the management of the power dissipation in these tight specifications. We discuss the other on a future occasion. The processors are all designed with 45-nm lithography and the physical properties were chip measures only 13mmx14mm. TrulyMiniature tools miracle!
