There is a whole class of enterprise CPU designed specifically for workstations and servers
Web Hosting & Data Storage Devices: AMD and Intel are two of the major players in this market, AMD with their Opteron processors, and Intel with their Xeon processors. As with the other CPU sectors, there is fierce rivalry between the two companies, and this competition is driving the technology forward very rapidly indeed. Server class CPUs typically have to perform very complex calculations as part of data-intensive business applications, and they also need to operate efficiently in a multi tasking environment, as they are often called upon to perform several tasks simultaneously. Because of their immense processing power, and the fact that they are often in use 24 hours a day, servers can have high power consumption requirements, so energy efficiency is increasingly becoming a critically important factor in the design of CPUs.
The latest server class offerings from Intel and AMD are quite different from a technological point of view. Intel’s latest Xeon processors are based on a revised form of their Nehalem architecture, known as Westmere, and feature 6 cores, while the latest Opteron CPU from AMD is based on their new Magny-Cours architecture, and features 12 cores. This means that the AMD processors have twice the number of cores, or separate processing components, as the Intel CPUs, so in theory can run more threads simultaneously without compromising on performance. However, the raw power provided by each core on the Intel processors is greater as they have higher clock speeds, negating some of this benefit.
AMD Opteron Server With 96 Cores
There is a growing customer demand for more performance in servers that consume less. Power consumption ceilings have been enacted for eco-friendly buildings, to encourage users to look for savings everywhere and particularly in their computer room. Dell works with suppliers of components to meet these needs in power and performance while reducing power consumption of its systems. HPC with this server, offers Samsung memory cards, Low Power AMD Opteron chips and integrating more cores as Intel Xeon, peaking at 8 hearts today. For now, Dell does not offer the server with Intel chips.
Dedicated Servers with GPUs deliver more raw power and consume more energy, but they also reduce the number of machines in the data center. Dell is working together with clients to develop test benches where the power of parallel computing CPU and GPU can be fully consolidated.
Based on the chassis C6105 introduced last September and can accommodate up to 48 processor cores in a 2U AMD, the C6145 supports up to 1TB of memory with a maximum of 96 processor cores. The dimensions of the server are from 44.8 centimeters (17.6 inches) wide and 79 cm (31.1 inches) in depth. Since AMD has previously announced, this server is “socket compatible” with the next-generation chip architecture based on Interlagos Bulldozer. The server comes with Suse Novell, Red Hat Enterprise Linux 5.5, Windows Server 2008 R2 or Windows HPC Server 2008.
