Recently, Intel has launched the new framework of historic significance of the processor KuRui – 2, although we are rarely seen in the market of these commonly known as the “double braised pork meat processor, Intel has” began its successor, with a technical processor will CSI battery.
If the Intel recently launched the chip is a server’s brain, “general system” (CSI) interconnection interface like its central nervous.CSI battery in 2008 will be introduced, it is a kind of new processor, other components of computer communication method.
CSI has two major changes. First, and the use of Intel chips communication technology, CSI will increase compared processor performance. Second, CSI will help Itanium server using the mainstream of designers Xeon server technology. The use of two kinds of Unisys so the processor is especially good server company.
Nathan Brookwood Insight 64 analysts said: “Intel technology can improve their hopes CSI chip market position in the server.
Besides, Intel plans to launch CSI battery integrated memory controller, the controller is located in main processor, not to separate chips supportive form. To do so would improve memory performance speed, and can also new CSI communication system supporting. The new chip communications system and the memory controller can help Intel counterattack AMD Athlon 64 processor and HT technology.
Meanwhile, Intel has used the other means with AMD, such as accelerated the competition capacity bus speed, increase the cache. Memory is the design of computer communication speed of a main factor. In order to ascend speed, designers intermediary will cache into the processor. But in the system, the processor cache becomes a problem. Each processor cache in coordination when may appear not synchronous phenomenon, in order to let each processor cache, must keep pace with changes in the other processors.
At present, the design of Intel’s called a tuner chipset through the chip in front of fieldbus control of the communication between each processor. But with the HyperTransport and CSI technology, the processor is directly each other directly.
Director of the department of Unisys company server Craig plays said: “CSI biggest advantage is improving performance, basically, is the direct communication between CPU, thus saving time.” Intel in explaining why insist that the front bus can adapt to a more extensive memory standards.
The server has CSI, the processor can exchange. Plays said: “from the point of Unisys, if a customer want a Itanium systems, we give him Itanium processor, then put it in our common platform. If it Xeon want yao, we also can satisfy their needs. Brookwood thinks, once the Intel chips with AMD communication technology level, it can better compete with AMD.
But to AMD has. In 2007, AMD will use HyperTransport 3.0. This technique to improve the communication speed, can use it to form and processor server system, and now only eight processors server system. In addition, AMD will have HyperTransport technology, it will be open one of its advantage.
