（3分）V．Reading Comprehension.( 22 points )Intel DX58SO MotherboardBottle necks slow down performance. This happens when the processor, or one of its core, is unable to fetch data or instructions fast enough. The memory of the computer system is particularly important because of the amount of data that is passed through it as the system receives instructions from the applications. Theoretically speaking, this means that the faster a processor receives data from memory, the better the performance.Traditionally, processors have been connected to the memory of a computer via an external bi-directional front-side bus (FSB). This bus served as the central connection point between the processors, the chipset that contains the memory controller hub, and all the other buses such as PCI, AGP, etc.Intel engineers know that having more powerful processors means that the architecture must also be upgraded to ensure that data flows more quickly between all the different components, and thus the Quickpath Interconnect was createdThe most notable element of the Quickpath architecture is that the memory controller is now integrated into each microprocessor. Each processor has a dedicated memory controller. In the event that a processor needs to access data from the dedicated memory of another core, it can do so through a high speed connection. This allows the cores to get data from memory controllers directly, and connection with other components of the system is also greatly enhanced. The technology is named Quickpath Interconnect because that is precisely what it offers: high speed connection between all the components.For this reason, the Core i7 processors can only be used on motherboards that support Quickpath Interconnect. The Intel DX58SO is one such example.The Intel DX58SO motherboard (codename “Smackover”) consists of the Intel X58 Express chipset with ICH10R south bridge chip. The ICH offers support for all the other devices such as video and audio. All buses and components operate on a 133.33 MHz base clock. In other words, a multiplier is applied to the base clock to acquire a speed value. There are four multipliers on the motherboard that affects the overall system speed. They are the CPU speed, the memory speed, the Quickpath Interconnect (QPI) speed, and the uncore speed. The first three are dedicated to overclocking. Uncore speed is the multiplier that is applied to devices that do not draw power from the processor. Together, these four multipliers manage the overall system performance.Besides support for the Core i7 processors (it supports all three editions), the DX58SO also offers other features, including integrated Intel audio, improved graphics performance, and the PCI Express 2.0 interface that delivers up to 16GB/s bandwidth per port.As all data and applications are stored on a systems hard drive, it is of utmost importance that the system is able to draw data from the drives very quickly. This is achieved through six SATA ports with transfer speeds of up to 3GB/s. For external storage devices, eSATA is available to help achieve the same performance.With the DX58SO motherboard, Intel actually emphasizes system stability significantly. For example, the motherboard features an exclusive fault tolerant BIOS that virtually eliminates downtime due to a corrupted BIOS.The new features certainly promise highly enhanced performance. However, how does the Core i7 perform under stringent hardware tests?Judge the Following Statements True or False:1．Theoretically speaking, the faster a processor receives data from memory, the better the performance. （）2．Traditionally, processors have been connected to the memory of a computer via an internal bi-directional front-side bus (FSB). （）3．The most notable element of the Quickpath architecture is that the memory controller is not integrated into each microprocessor. （）4．The technology is named Quickpath Interconnect because that is precisely what it offers: high speed connection between all the components. （）5．Smackover consists of the Intel X58 Express chipset with ICH10R south bridge chip. （）6．In the Intel DX58SO motherboard, all buses and components operate on a 133.33 MHz base clock. （）7．There are four multipliers on the motherboard that affects the overall system speed. （）8．For example, the motherboard features an inclusive fault tolerant BIOS that virtually eliminates downtime due to a corrupted BIOS. （）9．In other words, a multiplier is applied to the base clock to acquire a speed value. （）10．The uncore speed is dedicated to overclocking. （）11．The DX58SO can offer better speed, but it has nothing to do with graphics performance.
