In the fourth quarter of last year, INTEL formally released its long-fermented new generation processor Pentiumâ 4 , which is another great work of Intel and a powerful weapon in the specification battle of vital importance. Intel will vigorously recommend Pentiumâ 4 this year. It is expected that Pentiumâ 4 processor will become the main stream of mid-range and high-end desktop computer platforms on the market and replace the now prevalent Pentiumâ III. The emergence of Pentiumâ 4 will keep Intel in the lead in performance benchmarking contest.

Pentiumâ 4 improves the CPU operating frequency by a large margin and betters the performance, reflecting the huge potential of Pentiumâ 4 new architecture. As the new generation IA32 processor, Pentiumâ 4 has not used P6 architecture, instead, it has adopted the new architecture of NETBURST. The Streaming SIMD Extensions 2 and Hyper Pipelined Technology enhances the CPU performance by a large margin. The microcode-traced cache improves the efficiency of macro-program execution. The transmitting capacity of the front side bus can reach 400MHz.

The Intel 850 chipset that supports Pentiumâ 4 adopts the memory structure of RDRAM. The dual-channel RDRAM memory bus bandwidth can reach the theoretical peak value of 3.2G/sec, avoiding data blocking successfully and facilitating the acquisition of higher data transmitting speed. Compared with 1GB/sec-bandwidth of PC133 SDRAM and 2GB/sec-bandwidth of PC266 DDR, RDRAM has really made a big stride forward.

Legend QDI has designed PlatiniXâ 4 mainboard to match the Intel Pentiumâ 4 processor. This mainboard is based on Intel 850 chipset with its south bridge using ICH2. The entire board is an ATX 6-layer board, providing 4 USB ports, supporting ATA100, AGP4X and five PCI slots. There is one CNR slot on the board, supporting the expansion of software sound and software Modem and even upgrading to six-channels sound effect on the strength of CNR. PlatiniX 4-A has AC’97 sound effect on board while PlatiniX 4-L has ethernet (LAN) port on board. PlatiniX 4 board has four RIMM slots. It needs to be remembered that RIMM slot 1 and 3 form a channel while 2 and 4 form another. They together constitute the dule-channel RDRAM. For the dual-channel RDRAM, insertion of one channel is not enough. The two channels need to work simultaneously. Attention should be paid that when one RDRAM memory bank is inserted in one of the slots in a channel, the other slot can not be empty. C-RIMM memory module can be inserted to fill the vacancy.

The Pentiumâ 4 processor consumes more current than Pentiumâ III. In order to guarantee a sufficient power supply support and a stable system, Legend QDI PlatiniX 4 Mainboard designs a powerful three-phase power supply system. Besides the powerful power source support for CPU, separate power supply systems are designed for AGP4X and STR. This on the one hand guarantees the normal load and reduces mutual interference on the other.

In addition, four enhanced diagnostic LEDs are designed on the PlatiniX 4 mainboard. When there is any problem, the enhanced diagnostic LEDs will diagnose the case automatically and display the result in different colors so that the users can suit the remedy to the case.

On the PlatiniX 4 mainboard, Legend QDI’s innovation technologies are designed, including the just-released BootEasy, BIOS-ProtectEasy, SpeedEasy, ManageEasy and LogoEasy, providing a perfect high-end platform for the users.
