After so many years of development, the interface methods adopted by CPU are pin, card, contact and pin. At present, the interfaces of CPU are all pin interfaces, and the corresponding motherboards have corresponding slot types. Different types of CPU interfaces have different jacks in number, volume and shape, so they cannot be plugged into each other.
Socket 939
Socket 939 interface is the interface type adopted by AMD Athlon64 and AMD Athlon64 X2 series processors at present, with 939pin.
Socket 754
Socket 754 interface is the interface type currently adopted by AMD Sempron processor series, 754pin.
Socket 775
Socket 775 interface is currently the interface type adopted by Pentium D and Core 2 dual-core processors, with 775pin. A symbol of the dual-core era. //This article comes from the script house www.jb5 1.net, please indicate it when you reprint it.
Socket 478
Socket 478 interface is the interface type adopted by Pentium 4 series processors at present, with 478 pins. The Pentium 4 processor in the socket 478 has a small area and the pins are arranged very closely. Intel's Pentium 4 series and P4 Celeron series all use this interface.
Socket AM2
Socket AM2 interface, also called Socket 940, is the socket interface of Athlon 64 AM2 processor of AMD company at present. Socket AM2
The interface has 940 slots and can support 200MHz external frequency.
Socket a
Socket A interface, also called Socket 462, is the socket interface of AMD's Athlon XP and Duron processors. Socket A interface has 462 slots and can support 133MHz external frequency.
Socket 423
The socket 423 was the standard interface of the original Pentium 4 processor. The shape of the 423 socket is similar to that of the previous socket, and the corresponding number of CPU pins is 423. Socket 423 slots are mostly based on the motherboard of Intel 850 chipset, and support Pentium 4 processors of 1.3 GHz ~ 1.8 GHz. However, with the popularity of DDR memory, Intel developed the i845 chipset supporting SDRAM and DDR memory, changed the CPU slot to Socket 478, and the Socket 423 interface disappeared.
Socket 370
Socket 370 architecture is developed by Intel, not a socket architecture. It looks very similar to Socket 7, and it also uses zero-plug slots, and the corresponding CPU is 370 pins. Intel's famous "Copper Mine" and "tualatin" series CPU all use this interface.
Slot 1
Slot 1 is a patented CPU interface developed by Intel Corporation to replace Socket 7. In this way, other manufacturers can't produce products with slot 1 interface. The CPU of SLOT 1 interface is no longer a familiar square, but a flat cuboid, and the interface has also become a golden finger, no longer in the form of a pin.
Slot 1 is a slot designed by Intel Corporation for Pentium II series CPU. Pentium II CPU and its related control circuits and secondary cache are all on a daughter card, and most slots 1 motherboards use 100MHz external frequency. Slot 1 has advanced technical structure, which can provide greater internal transmission bandwidth and CPU performance. This interface has been eliminated, and there is no such interface product on the market.
Slot 2
Slot 2 is used professionally for high-end servers and graphics workstation systems. The CPU used is also expensive Xeon series. There are many differences between slot 2 and slot 1. First of all, the Slot 2 slot is longer and the CPU itself is larger. Secondly, Slot 2 is competent for more demanding multi-purpose computing, which is the key to enter the high-end enterprise computing market.
In the standard server design at that time, general manufacturers could only use two Pentium II processors in the system at the same time. With the design of slot 2, a server can use eight processors at the same time. Moreover, Pentium II CPU with Slot 2 interface adopted the most advanced 0.25 micron manufacturing technology at that time. Motherboard chipsets supporting SLOT 2 interface include 440GX and 450NX.
Slot a
SLOT A interface is similar to Intel's SLOT 1 interface, which is used by AMD's K7 Athlon. In terms of technology and performance, SLOT A motherboard is fully compatible with all kinds of original peripheral expansion cards. It does not use Intel's P6 GTL bus protocol, but uses Digital's Alpha bus protocol EV6. EV6 architecture is an advanced architecture, which adopts multi-thread point-to-point topology and supports 200MHz bus frequency.
The speed of 7
Super 7 interface motherboards are initiated by AMD, VIA, Ali, SIS and other manufacturers. Its biggest feature is that it directly supports 100MHz bus frequency and AGP graphics acceleration port, which prolongs the life of Socket 7 interface motherboard. Faced with the Socket 7 interface that Intel has abandoned, AMD and other manufacturers are not discouraged. They not only continue to produce CPU products supporting Socket 7, but also develop them into Super 7 products competing with SLOT 1. In fact, Super 7 is no match for Slot Point 1. AMD is well aware of this. However, in order to protect its production line from premature elimination and seize the low-end market, AMD is still very patient with Socket 7 products and directly evolved into Super 7 series.
Until a brand-new socket A interface product was developed. The chipset used in Super 7 includes VIA's MVP3 and MVP4 series, SIS's 530/540 series, and Ali's Aladdin V series. The products corresponding to Super 7 interface CPU are AMD K6-2, K6-III, Cyrix M2 and other manufacturers' products. However, at present, the market share of K6-2 is rapidly declining under the pressure of Celeron, so there are very few new Super 7 motherboards on the market, which are basically products of one or two years ago.
The following are the early CPU interfaces:
CPU interface type pin number pin supported CPU type
Socket 4 273 supports Intel 60mhz-66mhz p5t series cpu.
Socket 5 320 supports Intel 75mhz-166mhz P54C/P54Cs series cpu.
Slot 6 235 Intel 80486 DX4/ Pentium series cpu
Socket 7 32 1 supports Intel 75mhz-200mhz P54C/P54C/P55C series cpu.
Support AMD k5/k6-2/k6-3.
Support Cyrix 6x86/6x86L/M Ⅱ/MediagX.
Socket 8 387 supports Intel150 MHz-200 MHz Pentuim Pro series cpu.
