What is the motherboard chipset of a tablet?
Chipset is the core component of the motherboard. According to its arrangement position on the motherboard, it is usually divided into Northbridge and Northbridge. chip and Southbridge chip. The Northbridge chip provides support for CPU type and frequency, memory type and maximum capacity, ISA/PCI/AGP slot, ECC error correction, etc. The Southbridge chip provides support for KBC (Keyboard Controller), RTC (Real-Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33 (66) EIDE data transmission method and ACPI (Advanced Energy Management), etc. . Among them, the Northbridge chip plays a leading role and is also called the Host Bridge.
Intel still has the largest market share of mobile chipsets, and of course there are many manufacturers participating in the chipset competition. The competition between Taiwan's three chipset giants, Silicon Integrated Systems (SIS), VIA, and ALi, as well as graphics display chip overlords ATI and NVIDIA, is becoming increasingly fierce.
For the Centrino platform, Intel has launched the INTEL 855 series of mobile chipsets. The Intel 855 series of mobile chipsets include the independent Intel 855PM and the integrated graphics display chip. Intel 855GM. Intel 855GM integrates an improved Extreme Graphics2 graphics core. The INTEL 855GM chipset with built-in graphics is mainly used in entry-level Centrino notebook products, while the INTEL 855PM chipset is mainly used in matching powerful independent graphics cards and higher-frequency Centrino processors. Among mid-to-high-end products. Supporting Intel Pentium4-M and Celeron4-M are the Intel 852 and Intel 845 series chipsets. Among these Intel products, the performance of Intel 852 is very good, and it is also the main chip used by many P4-M models.Film set.
In addition to INTEL, only SiS has launched a corresponding chipset that matches Centrino. Not long ago, SiS released a new chipset specifically for notebooks that supports Centrino architecture. The chipsets released by SiS are independent chips - SiS648MX and integrated chips SiSM661MX. These chipsets are specially designed, researched and developed for Intel mobile Pentium-M processors. SiS M661MX chip and 648MX chip are the first non-Intel chipset products authorized by Intel to support Centrino processors. The SiS M661MX and SiS648MX chipsets are both functionally and technically excellent, comparable to Intel's 855PM and 855GM chipsets. I believe that SIS's chipset products supporting Centrino technology will definitely make waves in the market. In the third quarter of 2003, SIS released the SIS 661FX notebook chipset, which can support various Pentium4 processors with 800MHz FSB. 661FX also integrates Ultra AGP graphics chip, supporting DDR400 with a maximum resolution of 1600×1200.
As the licensing policy begins to loosen, Pentium M supporting chipsets will become more and more abundant. Next, VIA has also been authorized by Intel, and VIA has taken the lead in releasing two chipset products PN800 and PN880 that support the Pentium M processor platform, targeting the notebook entry-level market and high-end products respectively. What's even better is that these two products actually fully support Intel Celeron M and Intel Mobile Pentium 4 processors, and support 400, 533 and 800MHz processor front-side buses. In addition, VIA, which has always been a two-pronged approach, has also spared no effort in supporting AMD Athlon64 64-bit mobile processors. VIA's K8T400M chipset is already ready for mobile Athlon64.
ATI and NVIDIA, the pair of display chip giants, are now slightly involved in the chipset field. For example, we were familiar with ATI has launched the RADEON IGP 320M chipset for Athlon 4 and Duron mobile processors and the RADEON IGP 340M chipset for Pentium 4-M. NVIDIA has also launched corresponding notebook chipsets that support AMD Athlon 64 processors. The intervention of ATI and NVIDIA in the AMD chipset market has greatly strengthened the AMD mobile processor supporting platform. ALi is also a member of the mobile chipset army. Its products are very unique and have certain manufacturer specificity. However, the market The share is not very high.
Medium and high-end notebooks generally use INTEL motherboard chipsets. This is because INTEL mobile chipset products have high stability and low energy consumption. However, due to the mobile INTEL motherboard chips. The set is expensive, which directly leads to a higher price for notebooks. Therefore, some mid- to low-end notebooks use chipsets from Taiwan’s Silicon System Technology. High integration characteristics. Therefore, SiS chipset products are widely used and have a good reputation in the industry for their stable quality. Although VIA is also one of the three major motherboard chipset manufacturers in Taiwan, VIA's focus has always been on desktop motherboard chipsets. In the field of notebook motherboard special chips, it is slightly inferior.
Front-side bus
Front-side bus speed It refers to the data transmission speed, the unit is Hertz. For example, the 100MHz FSB means that the digital pulse signal oscillates ten million times per second. It is the FSB that uniquely determines the frequency of the front-side bus - the front-side bus connects the CPU and the computer. north bridgechip bus. The front-side bus frequency of the AMD system is twice the CPU FSB, while on the P4 platform it is four times the CPU FSB. Only on the old Athlon and PIII/PII platforms, the front-side bus frequency is equal to the FSB.
