What are the common server CPUs

In fact, the server CPU, that is, the CPU on the server is a very important device of the network. It needs to be accessed by users and has a significant impact on the throughput and stability of data. So what common server CPU is there on the market?

The Chinese meaning of CISC type CPU is "complex instruction set", which refers to the x86 series CPU produced by Intel and is also compatible with other manufacturers' CPUs. The CISC CPU is based on PC architecture. The structure of this CPU is usually 32-bit, so the CPU is also called IA-32 CPU. CISC CPUs currently mainly include Intel server CPUs and AMD server CPUs.
The Chinese meaning of RISC CPU is "reduced instruction set". RISC CPU is developed on the basis of CISC's original instruction system. Tests on the CISC machine show that there are large differences in the frequency of use of some of the instructions. Some of the more common simple instructions only account for 20% of the total number of instructions, but the frequency of use in the program has reached 80%. The use of complex instruction systems will definitely increase the load type of the microprocessor, prompting the processor to increase the time and cost of development, and at the same time cause the speed of the computer to decrease.
The RISC CPU introduced on the basis of CISC instructions not only streamlines the CPU instruction system, but also uses "superscalar and super pipeline structure", which effectively speeds up parallel processing capabilities (parallel processing refers to the same server There are multiple CPUs for processing at the same time. This parallel processing can effectively improve the server's ability to process data). That is to say, the CPU using the RISC architecture is much higher in performance than the CISC CPU under the same frequency architecture, which is also determined by the technical characteristics of the CPU. At present, some high-end servers use RISC instruction system CPUs, especially in some high-end servers, RISC instruction system CPUs are used.
The above is the analysis of the content of the server.

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

SSD vs. HDD: that is nice for You?

Deciding on the proper garage isn’t just about comparing ability and value. The type of garage your pc uses topics for overall performance, inclusive of electricity utilization and reliability. Stable country drives (SSDs) and difficult disk drives (HDDs) are the 2 major storage options to consider and it’s critical to realize the satisfactory use for each and how they compare facet by using aspect. What is an HDD? An HDD is a statistics garage tool that lives within the pc. It has spinning disks inside where statistics is saved magnetically. The HDD has an arm with several "heads" (transducers) that study and write statistics at the disk. It is much like how a turntable file participant works, with an LP record (tough disk) and a needle on an arm (transducers). The arm moves the heads throughout the surface of the disk to get admission to distinct information. HDDs are considered a legacy generation, that means they’ve been round longer than SSDs. In popular, they may be dec
