What is the difference between server CPU and ordinary CPU?



1. Different cache


The cache also determines the performance of the CPU. Because the server CPU has high requirements for computing performance, the server CPU often applies the most advanced technology and technology, and is equipped with one, two, and three levels of cache, which makes it more powerful. The server CPU has long used the level 3 cache. Ordinary CPUs have only used caching technology in recent years.

2. Different interfaces


Server CPU and ordinary CPU interfaces are often different. At present, server CPU interfaces are mostly Socket 771, Socket 775, LGA 2011, LGA 1150. Compared with ordinary CPU interfaces, although many of them are the same, the motherboards are actually different. The motherboards equipped with server CPUs usually do not have graphics card slots, because the core graphics cards that come with the CPU can meet the demand, and the CPU bus bandwidth is higher than that of home CPUs.

3. Different stability requirements


The server CPU exists for long-term stable work, and is basically designed to work continuously all year round. Compared with home CPUs, server CPUs are very different in terms of stability and reliability. Generally, servers are turned on and run 365 days a year, and only occasionally shut down for maintenance, which requires extremely high stability.
Ordinary CPU is designed for 72 hours of continuous work. When the home computer is not in use, we are still used to keeping it in the off state, usually every day.

AMD's GPU technology enters the mobile phone chip market for the first time

In addition to the release of the Exynos2100 processor, Samsung also confirmed a major event at this Exynos event, that is, the custom GPU that they have worked with AMD for many years will soon appear and will be used on the next flagship machine. The current Exynos2100 processor uses ARM’s Mali-G78GPU core with a total of 14 cores, so the GPU architecture developed by Samsung will be the next Exynos processor, and the GPU will be the focus. This is probably the meaning of Exynos2100’s GPU stacking. The key reason. Dr. InyupKang, president of Samsung’s LSI business, confirmed that the next-generation mobile GPU in cooperation with AMD will be used in the next flagship product, but he did not specify which product. Samsung is not talking about the next-generation flagship but the next one, so it is very likely that a new Exynos processor will be available this year, either for the GalaxyNote21 series or the new generation of folding screen GalaxyZFold3. In 2019, AMD and Samsung reached

Apple and Intel want to join the game, what happened to the GPU market?

Intel recently announced that it will launch Xe-LP GPU at the end of this year, officially entering the independent GPU market, and will hand over to TSMC for foundry. At the 2020 WWDC held not long ago, Apple also revealed that it is possible to abandon AMD's GPU and use a self-developed solution based on the ARM architecture. It will launch a self-developed GPU next year. What happened to the GPU market? Why are the giants entering the game?    Massive data calls for high-performance GPU    Why has the demand for GPUs increased so rapidly in recent years? Because we are entering an era where everything needs to be visualized. Dai Shuyu, a partner of Aiwa (Beijing) Technology Co., Ltd., told a reporter from China Electronics News that visualization requires a large amount of graphics and image computing capabilities, and a large amount of high-performance image processing capabilities are required for both the cloud and the edge.    Aiwa (Beijing) Technology Co., Ltd. is an enterp

NVIDIA officially launches RTX 30 series mobile graphics cards

In the early morning of January 13, NVIDIA officially launched the RTX30 series of mobile graphics cards at the CES2021 exhibition. Ampere-based GPUs have also reached the mobile terminal, mainly including RTX3080, RTX3070 and RTX3060 models. In addition to improving game performance, the RTX30 series of mobile graphics cards have twice the energy efficiency of the previous generation, and support the third-generation Max-Q technology, mainly supporting DynamicBoost2.0 dynamic acceleration technology, WisperMode2.0 noise control, ResizableBAR (similar to AMD’s SAM technology) and DLSS. The third-generation Max-Q technology uses AI and new system optimization to make high-performance gaming laptops faster and more powerful than ever. These technologies include: ·DynamicBoost2.0: The CPU and GPU powers of traditional gaming notebooks are fixed, while games and creative applications are dynamic, and the requirements for the system will vary with the number of frames. With DynamicBoost2.0,
