Has Intel really replaced Itanium with Xeon

Processor socket

descriptiondescriptionBase 1Processor socket with 238 pins for Intel 486 SX.Base 2Processor socket from 486 DX2 with a supply voltage of 5V.Base 3Processor socket with 237 pins from 486 DX4 with a supply voltage of 3.3V or 3.45V.Base 4Processor socket with 273 pins from Pentium 60 and 66 (P5) with a supply voltage of 5V.Base 5Processor socket with 320 pins for Pentium processors from 75 to 133 MHz (P54C) and a supply voltage from 3.3V to 3.5V.Base 6Intended for the 486, but was never used (235 pins).Base 7Successor to Socket 5 for Pentium processors and the most popular socket for processors with 321 pins of the 5th and 6th generation from AMD and IBM / Cyrix as Super Socket 7 with 100 MHz FSB.Base 8Only the Pentium Pro with 387 pins from Intel fits into this socket.Slot 1This processor connector (242 pins) was introduced with the Pentium II. It is also used for the Pentium III. Since the processor with L1 and L2 cache is housed on a circuit board in a module, this socket is more like an expansion slot. In principle, slot 1 is nothing else than socket 8. GTL + is used as the protocol.
The large slot cartridges quickly lost their right to exist again. They were used to couple the processor core with a fast L2 cache. With the introduction of the 0.25 µm manufacturing process, it made sense to integrate the L2 cache directly into the processor chip (die).Slot 2Slot 2 with 330 connections is the high-end processor socket for Intel's multiprocessors Pentium II Xeon and Pentium III Xeon.Base 370After the Pentium III processors had an integrated L2 cache on which the die, a circuit board design was no longer necessary.
That is why Intel introduced the PGA design, which was electrically and not all compatible with one another in terms of pin assignment.
All Pentium III processors with a clock frequency of more than 1 GHz, regardless of whether they are manufactured using 0.18 or 0.13 µm technology, come in the new FC-PGA2 housing with integrated "Heat Spread" (IHS). This sheet distributes the heat released in the processor die better and thus avoids hotspots (local overheating).
The processors from VIA (Cyrix III and C3) also fit into the socket with 370 pins. The different processor voltages make the processors incompatible with one another.Slot ASlot A is for the Athlon from AMD.
The slot design of slot A (242 pins) is basically a mirror-inverted slot 1. The EV6 protocol is used as the protocol. This is the same protocol used on the Alpha processors. Theoretically, such an alpha processor could be plugged into slot A.Base A
(Socket 462)The AMD processors Thunderbird and Duron are only available for socket A with 462 pins. Slot A has already had its day.
Socket A was later also used for the Athlon XP and Sempron.Socket 423Processor socket with 423 pins for the Intel Pentium 4 from 1300 to 2000 MHz (until 2001).Socket 478Processor socket with 478 pins for the Intel Pentium 4 from 1400 MHz and Celeron from 1700 MHz and Celeron D.Socket 479 Intel Pentium M (Banias, Dothan), Celeron M (Banias, Dothan, Yonah) Slot MTo ensure the required bandwidth for the IA-64 processor generation (Intel Itanium), Intel introduced the M slot. The earth lines are routed to the processor housing via an extra connector. The data lines come via a separate connection.
HP uses a similar technology in its RISC PA-xxxx processors.Socket 603Intel Xeon FSB400 Socket 604Intel Xeon 3.06 GHz FSB533Socket 754 This base was first used for the Athlon 64, but was then replaced by the base 939. Socket 754 was used for the long term for the AMD Sempron and for the Notebook processors Mobile Athlon 64, Turion 64 and Mobile Sempron.Socket 939This socket has twice the memory bandwidth than socket 754. In addition, it uses HyperTransport throughout instead of the classic FSB. AMD Athlon 64 and AMD Athlon 64 X2.Socket 940Originally the socket 940 was intended for the Opteron. Then AMD abused this socket for the Athlon 64 FX series, which are nothing more than Opterons.Socket 775
(LGA775)Instead of pins on the underside of the processor, flat contacts in the socket press on small leaf springs, creating a connection. A hinged cover with a modified locking method presses the CPU firmly into the socket. This procedure is intended to provide a better connection and prevent bent pins. The socket has a total of 775 contacts.
For Intel Pentium 4, Celeron D, Pentium D, Pentium 4 Extreme Edition and Core 2 Duo / Quad.ON 2The Athlon 64, Athlon 64 X2 and Sempron with the AM2 socket and DDR2 memory interface have been available since May 2006.
With the AM2 socket, AMD resolves the confusion of two sockets. This means that a motherboard can be equipped with different processors without taking the socket into account. This not only pleases the manufacturers, but also the customers who assemble a computer themselves.
The AM2 is very similar to the Socket 939. At first glance, they only differ in a few pins. But both sockets were developed for different types of storage.Socket 51Socket for the notebook processors AMD Turion 64 X2.Base M Core Solo / Duo (Yonah), Core 2 Solo / Duo (Merom), Pentium Dual Core (Yonah), Celeron M (Yonah, Merom) Base P Intel Core 2 Duo / Extreme (Merom, Penrym), Celeron M (Merom) AM2 +Extension of Socket AM2 for AMD Phenom X3 / X4.AT 3The AM3 socket is used for cheap Athlons and Phenoms from 2 cores (X2 / X4).AM3 +The FX series from AMD with a slightly modified AM3 socket.FM1The FM1 socket is used for the A series (A8, A6, A4) from AMD.FM2The FM2 socket is used for the A series from AMD.Base F
(LGA1207) The Socket-F is the processor socket for the AMD Opteron 22xx and 82xx with LGA1207 housing.Base B
(LGA1366)The LGA1366 is a socket for servers and workstations. This base is too expensive for the mass market. Systems with LGA1366 are only worthwhile if you need a lot of main memory and more than two graphics cards.
Socket for Intel Core i7 needs so many contacts because it needs a lot of power supply connections, the three-channel memory connection and Quick Path Interconnect (QPI).Base H1
(LGA1156)The LGA1156 is a slimmed-down LGA1366 with only two memory channels and a PCIe controller instead of QPI. The socket is cheaper and suitable for processors and motherboard wheels for the mass market. More than half of the 1156 contact surfaces are used for the power supply.Base H2
(LGA1155)The LGA1155, also known as the H2, is generally used for most Intel CPUs. For example Core i7, i5, i3, Pentium and Celeron.Base LS
(LGA1567)Successor to the LGA1366 server socket. Three additional QPI links, each occupying 59 contacts, explain a large part of the 201 connections that LGA1567 offers more than LGA1366.LGA2011The LGA2011 is intended for server processors (Xeon) and certain Core i7 variants. The enormous number of contacts is due to the four memory channels for DDR3-1333 and 40 PCIe lanes.
