How to identify the number of physical CPUs, a few cores, is hyper-threading or multi-core
Judge the basis:
1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores.
English version:
1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any CPU with the same physical ID are threads or cores in the same socket.

Last week at the customer exchange, a boss asked me why the formal site design is at least 2000 yuan, the highest or even tens of thousands, but a lot of web service providers are cheap, more than 1000 pieces, or even hundreds of pieces, why an industry has such a disparity in the price, cheap in the end where cheap?Here to summarize some of the hope can be a poi

This low-cost supercomputer runs about 500 trillion tflop per second, which makes it possible to do floating-point operations in a second.Some of the other components that are cheap and suitable for building home supercomputers include

Computer Hardware Reviews:
Although the cost of DIY computers is getting cheaper, but also not to include CPU, graphics, memory, hard disk, chassis power and other computer host, the price is low to hundreds of yuan, this is obviously a trick.

less likely to result in performance degradation. In daily use, the actual power consumption of these processors is often lower than the TDP is 95W normal desktop processor. I was asked why E3-1230v3 did not have a core video card, TDP in 80W, and i7-6700 has a core video card, frequency and E3 like, TDP but only 65W? Because the Xeon E3 series is designed for workstations, high load data design, Rendering will greatly depend on the stability of the

For many enterprise users, performance is not the primary factor for server selection. The most important indicator is low power consumption and capital budget. AMD's latest haolong 4100 series processor is developed and designed for such users. The 4100 series is a low-level version of The Magny-Cours codenamed mainiku core haolong 6100 series processor. Haolong 6100 has two versions: 8-core and 12-core. In contrast, the "Lisbon" haolong processor is only a single core.
