Common CPU Interfaces

Socket 478

Intel recently plans to enable all Pentium 4 series processors to adopt the new socket478 package. This is due to the 0.13 micron process, and the Pentium 4 processor based on the Northwood core must use the socket478 package. By the fourth quarter of this year, the frequency of the series of processors will exceed 2 GHz. Under pressure from motherboard manufacturers, Intel is preparing to increase the output of the Willamette core socket478 processor. The reason is that the Northwood-based processor is expensive. After all, the 0.13 micron processing technology it uses is relatively advanced, so their prices cannot be reduced to the Willamette core processor price in the short term. For this reason, motherboard manufacturers are afraid to produce too many brooket478 Boards Based on the Brookdale (i845) chipset.

Socket

Intel's fear of athlon forced them to launch new chipset and CPU. AMD has strengthened their position in the market with its latest products. AMD has a small share in the CPU market, but with its K7 family of processors, AMD has already placed intel in the first army. This socket A is now AMD's powerful weapon against Intel. The main board of this interface is mostly based on kt133a, 266a and other via chipset boards.

Socket 423

Early Pentium 4 series Processors all use socket423 encapsulation, but this interface has been eliminated and is not recommended for purchase.

Slot 1

The slot 1 interface has always been Intel's patent, so the motherboard using this interface supports Intel's processor without exception. Intel originally launched the slot 1 interface to monopolize the future development trend of the motherboard. However, the rise of Super 7 disrupted Intel's perfect plan. Maybe we want to use someone else's hand to expand the market. Intel then granted the manufacturing authorization for the slot 1 Structure motherboard to motherboard manufacturers such as via, sis, and Ali, therefore, these manufacturers have also released a series of mainboards using the slot 1 interface, enriching the main board market. The technical structure of Slot 1 is relatively advanced, providing greater internal transmission bandwidth and CPU performance, which is also the reason why intel is determined to abandon socket (but later intel went back to the old path ), currently, the mainstream motherboard chipsets Using slot 1 interfaces include Intel's BX, i810, i820, and via's Apollo series, alibaba's Aladdin pro II series and SIS 620 and 630 series. The performance of the motherboard With Different chipset designs is also different, and some of them are integrated into the motherboard, which needs to be carefully identified. However, with the popularity of the socket 370 structure motherboard, the current sales of the slot 1 Structure motherboard is not as good as before, giving a lot of market share to the new socket 370 structure motherboard.

Slot 2

Slot 2 is probably out of touch with our civilian diyer. It is used professionally: it serves high-end servers and graphics workstation systems. The CPU used is also a very expensive Xeon (Xeon) series. The main board using the slot 2 interface has more than two CPU slots for the multi-processor to work at the same time. The Motherboard chipset that supports the slot 2 interface includes javasgx and javasnx.

Slot

Slot A interface is another product of AMD in order to compete with intel. The slot a motherboard is used by AMD's main product K7 athlon. In terms of technology and performance, the slot a motherboard is fully compatible with various peripheral expansion card devices. However, it does not use intel's P6 GTL + bus protocol, but digital's Alpha bus protocol ev6. The ev6 architecture is currently the most advanced architecture. It adopts a multi-threaded point-to-point topology structure and supports bus frequencies of MHz, which undoubtedly lays a good speed foundation for K7. Currently, there are two main types of Motherboard chipset that support slot A interface structure. One is amd 750 chipset, which is independently developed by AMD, and the other is via's Apollo kx133 chipset, there is also the active via ktsung chipset. However, due to the fact that there are not many K7 motherboard manufacturers, both in terms of output and product compatibility, AMD is facing many unfavorable difficulties, to reduce manufacturing costs and reduce the CPU design and production cycle, AMD has developed the latest socket a series motherboard. As the successor of Slot A interface, it adopts the 462-pin interface design, supports the latest athlon (Thunderbird) and duron (diamond) CPUs, which reduces manufacturing costs and simplifies structural design, just like socket 370.

Socket 370

To expand the low-end market and combat AMD's product sales, Intel decided to promote their low-cost competition for a CPU. When the horse matches the saddle, sai Yang A is transformed into a socket 370 structure, and the corresponding cheap socket 370 motherboard appears. Most socket 370 motherboards use intel ZX, BX, and i810 chipset products. Of course, other vendors such as via and sis will also participate, such as via Apollo pro and SIS 530 series. Originally, there was a view that the CPU upgrade capability of socket 370 may not be very good, so the sales of socket 370 is always inferior to that of the motherboard of Slot 1 interface. However, Intel is constantly changing its strategy. In the new millennium, with the introduction of Intel Coppermine series CPU new p iii and sai yangⅱ (both socket 370 structure design, as soon as the motherboard of the socket 370 interface changes its low-end image, it gradually becomes the mainstream of the CPU interface structure motherboard. For example, the latest i815 series motherboard adopts the socket 370 structure design. The socket 370 structure absorbs the advantages of the original motherboard structure: low cost, simple design, and wide support. On the contrary, the motherboard of the original slot1 interface has suffered a blow and is rapidly disappearing from the main board market. For some slot1 interface boards, a socket 370 adapter is the best partner to upgrade and develop it. In general, the socket 370 motherboard represents the mainstream of the current and the next year, and is recommended!

Super 7

the Super 7 interface motherboard was created by AMD, via, Ali, sis, and other vendors. Its maximum feature is its direct support of MHz bus frequency and the AGP graphics acceleration port, extending the life of the socket 7 interface motherboard. In the face of socket 7 interfaces abandoned by Intel, AMD and other vendors are not discouraged, not only continue to produce CPU products that support socket 7, but also develop it into a super 7 product that competes with slot 1. In fact, Super 7 is not the opponent of Slot 1. AMD knows this clearly. However, in order to protect its own production lines from being eliminated early, it also stepped up to take over the low-end market, AMD is still patient with socket 7 and directly converts it into the Super 7 series. The new socket ainterface product was developed. Super 7 adopts the mvp3 and mvp4 series of via, SIS 530/540 series, Ali Aladdin V series and other motherboard products. Corresponding Super 7 interface CPU products include amd K6-2, K6-III, cyrix m2 and some other manufacturers of products. However, due to the current K6-2 under the suppression of the rapid reduction of market share, so the current market on the new super 7 motherboard has been very rare, basically still one or two years ago products.
