Who is the replacement slot expert? There are 29 CPU interfaces!

This morning "News Tea Fan" about the follow-up news of AMD AM4 interface really made everyone very happy, follow-up smooth upgrade was so easy, no wonder Ryzen is full of praise this year. However, this news also attracted the interest of Xiao Bian. It took half a day to review the data and carefully counted the number of CPU interfaces. Since Intel and AMD have each introduced their own unique CPU interfaces, there are a total of 29 types!

Do not change mouth? Can not do it!

Each generation of CPU upgrade, interface replacement related to whether the old motherboard supporting equipment can continue to use - this means that users can not upgrade smoothly and reduce upgrade costs. But the results are often disappointing. What caused this situation?

The first is naturally a technical problem. For example, when you look at the CPU technology upgrades of each generation, CPU interfaces are often incompatible. For example, memory specifications change, PCI-E specifications increase, and multi-core applications, even changes in power consumption, will affect The interface is replaced when the CPU is replaced.

For example, the memory controller is integrated in the CPU. Once the memory support specification is upgraded or even replaced, the CPU needs to increase the pin count to meet the memory bandwidth requirement. In this technology upgrade, the interface must be replaced.

One of the most extreme examples is the 8-generation Core processor. Although it is LGA1151 like the previous generation, the pin definition has changed dramatically due to the change in the number of cores. The number of negative pins on the 8th generation is higher than that on the 7th generation. There are 14, and there are 18 more power pins, which is expected to deal with the increase in power consumption after the core is increased, while keeping the pin count down from 46 to 25. Obviously, if you force the 8-generation Core Duo into the 100 series or 200 series, it will cause system instability or even damage the computer.

And now that the CPU is getting more and more complicated, electrical performance requirements are getting higher and higher, and the number of pins is bound to increase. For example, the Slot1/A interface introduced by Intel and AMD in 1999 only had 242 pins. Today's Intel Core i9 pin reaches 2066, and the AMD ThreadRipper pin actually reaches 4094! This is not only the difference of memory controllers, but also the demand for the number of cores and the inevitable requirement of ultra-high power consumption.

We are serious about selling goods!

In addition to technical requirements, are there really no market requirements? Anyway, Xiaobian does not believe, but there is one point, whether it is market requirements or technical requirements, the replacement of the interface is definitely not a certain factor to promote, it is inevitable that the demand is superimposed on many aspects to lead to interface replacement, which is beyond doubt.

The difference between the old and new motherboards must be reflected in the change of the card is not news, the same motherboard replacement small upgrade is a natural thing, no way, who calls the current PC market demand is not strong? Only upgrading a little function or specification, the motherboard chipset will have to be replaced, and the corresponding CPU interface will naturally have a "need" for the upgrade. For example, 100, 200, 300 series chipsets, you can not say that there is no technical upgrade between them, but the upgrade really needs to be such a small pace to achieve it? Xiao Bian thinks not necessarily.

Another factor in the market is that if the old motherboards are in stock, then the CPU vendors must see the motherboard makers' requests. They either delay the CPU life or delay the life of the motherboards. They can only choose one of them. After all, they are common. The interests of the collective Well.

Oh! It was him who changed the interface.

Do you think Intel is the smartest interface changer? Take a look at the following table, Xiao Bian excludes all interfaces before Socket 7 (after all, whether Intel or AMD interfaces are unified), the details of all the different CPU interfaces are listed in recent years, see who It is a small expert for changing interfaces!

First come Intel:

Let's take a look at AMD:

It can be seen from the beginning of 2000 to 2017, including the LGA1151 (once different from the previous definition of the array of positions), Intel has released a total of 14 kinds of sockets; the AMD is in the past ten years. Between the launch of 15 kinds of slots! Of course, AMD has too many stories in the AM1 to AM3 interface, and not much to say here. We can see that in fact, whether Intel or AMD, due to technical upgrades, because of market demand, the frequency of replacement of their interface is actually almost the same, and this is by no means caused by a single factor, a variety of factors will lead to CPU interface non-stop upgradin. Do you understand this?
