The Intel® Xeon® 7400 Processor was officially announced just a few weeks ago and there has been phenomonal interest in this product because of it's world record breaking performance leadership as well as it's great energy efficiency.
Let's first discuss one of the primary advantages of the Intel® Xeon® 7400 Processor: Up to 50% better performance/watt and up to 10% less system power vs. 7300. As stated, this is pretty straightforward: Intel has real world results that show significant performance increases while consuming less power as compared to servers based on the previous generation Intel® Xeon(R) 7300 Processors. The performance increase can largely be attributed to designing the Xeon® 7400 processor with 6 cores based on the Intel® Core™ Microarchitecture. In addition, the primary reason for the power decrease is because Xeon® 7400 uses the latest 45nm High-K process technology instead of 65nm in the previous generation. In general, processors based on the 45nm process consume less power than the processor's rated TDP (thermal design power) value. It must be noted that power consumption can vary by processor and some processors may consume even less power and others may consume up to the processor's rated TDP value. For more details on both the performance and power, I recommend taking a look at this 3rd party review by Anandtech*: http://it.anandtech.com/IT/showdoc.aspx?i=3414&p=1
Next, let's discuss the positive impact these servers can have on your data center. Whether you have an existing data center or plan to build a new one, there is always a fixed amount of power that is provided to that data center. Energy efficient performance, in it's simplest definition, is the ratio of performance in relation to the amount of power consumed. The higher the ratio, the more energy efficient your data center is. To accomplish this, two vectors need to be considered. The first is performance output and the second is power consumption (both when servers are operating at peak performance and when they are running at lower utilization levels or at idle). Servers based on the Intel® Xeon® 7400 processor can provide both higher performance as well as lower power, which offer some very compelling energy efficiency benefits. For example, when using virtualization multiple applications that currently run on independent servers can be consolidated on fewer, higher performing servers, while still providing performance headroom for future growth. By doing this, both acquisition and ongoing electricity/operational costs can be dramatically reduced. To see how much money you can potentially save by upgrading to servers based on the Intel® Xeon® 7400 processor, take a look at the ROI using the Intel® Xeon® Server Estimator at www.intel.com/go/xeonestimator
In summary, the best energy efficient performance can achieved using servers with Intel® Xeon® 7400 Processors. These servers provide both exceptional performance across a wide range of applications, with headroom to grow, while at the same time consuming less power as compared to previous generation Intel 7300 based servers.
