Help Me Choose: Intel processor

 
The processor plays an important role in your server’s ability to support internal business applications and respond to external customers. Since processors are continually changing, it can be difficult to determine which one is right for your application. You want to balance these considerations such as cost and features with your expected performance needs when selecting a CPU. This guide will help you make the best decision.

Dell's 11th generation platforms with the Intel® Xeon® processor 5600 series deliver exceptional performance, data bandwidth and power efficiency that enable IT to get the most out of each server — over original Intel Xeon processor 5500 series!*

Selecting the CPU that’s right for you

The Xeon 5600 CPUs are split up into three main groups: the E, L and X series. Each series is targeted to deliver the right blend of performance, price and features depending on your usage requirements.

Read the Features & Benefits tab for specific details about Intel Xeon processor 5600 series innovations. Note that moving between bands can yield significant performance gains. For example, moving from a “E” series part (Xeon E5640) to an “X” series part (Xeon X5650) can achieve up to 39 percent higher on an integer-based throughout workload (SPECint_rate_base2006)*


.
This tab lists the main features of the Intel Xeon processor 5600 Series along with the benefits you can realize for your workloads.

Higher is better: Better performance for a majority of server workloads

 

Processor Core Frequency up to 3.33GHz with 6 cores (3.46GHz for 4 cores)

Simply put, servers with higher core frequencies deliver better performance. Buying a higher frequency processor improves your current system performance while also helping ensure that your server can handle tomorrow’s increased demands.

Intel turbo boost technology

Boosts performance increasing processor frequency up to 400MHz above the rated frequency on Advanced Xeon 5600 SKUs*

Shared L3 cache up to 12 MB

This indicates the size of high-speed memory located on the processor. 50 percent larger shared cache size than Xeon 5500 reduces the frequency that the CPU needs to retrieve data from the system memory or hard drives, thereby boosting performance while reducing traffic to the processor cores

Higher is better: Better performance for bandwidth-intensive workloads

Intel QuickPath Technology speeds up to 6.4GT/s (25.6GB/s) per link

Higher QPI speeds provide a faster link between CPUs and I/O devices, such as hard drives and networking controllers and deliver up to 5.2x bandwidth improvement for data-intensive applications.

DDR3 memory speeds up to 1333MHz

Faster memory speeds and higher memory capacity reduces latency and increases performance by keeping more data closer to the CPU. NOTE: Using faster DDR3 memory may decrease the total amount of system memory that can be populated.

"ON" is better: Better performance with multithreaded workloads


Intel hyper-threading technology

 Enables each CPU core to run 2x the software threads for better performance on parallel, multithreaded apps, up to 24 threads in a single two-socket platform*.
