As Paul Steeves mentioned this morning, the PowerEdge R820 is a 4-socket 2U rack server that packs a lot of processing power into a dense form factor. He has a lot of great proof points in his blog that I recommend reading.
In addition, today Intel touted multiple industry-standard SPEC benchmarks using the PowerEdge R820 on their E5-4600 performance page; in fact, the Dell PowerEdge R820 was the only partner platform highlighted by Intel at launch! Check out Intel's graphs below for reference:
As you can see, the PowerEdge R820 shines in overall performance (as measured by SPECint, SPECfp, and SPECjbb), yet does not sacrifice on energy efficiency, as proved out by SPECpower_ssj2008!
The PowerEdge R820 is also great for HPC enviroments such as LINPACK; we've measured 649.2 GFLOPS in our lab, an 85% improvement above the 351.6 GFLOPS we measured on the R720!
We've got some other very interesting performance comparisons using the extremely powerful (but power-efficient!) PowerEdge R820 coming up, so stay tuned to this blog for more information!

LINPACK configuration: PowerEdge R820, 4 x Intel Xeon E5-4650 as compared to PowerEdge R720, 2 x Intel Xeon E5-2690 processors.
