Xeon E5-2651 v2 vs E5-2697 v2
Description
Both models E5-2651 v2 and E5-2697 v2 are based on Ivy Bridge architecture.
"Ivy Bridge is the last Intel microarchitecture for which there is official driver support for Windows XP . It is made under 22 nm Tri-Gate transistor (""3D"") technology and is basically a Sandy Bridge shrink. It has PCI Express 3.0 support and RdRand instruction for security tasks."
Using the multithread performance as a reference, the E5-2651 v2 gets a score of 426.2 k points while the E5-2697 v2 gets 633.1 k points.
Summarizing, the E5-2697 v2 is 1.5 times faster than the E5-2651 v2. To get a proper comparison between both models, take a look to the data shown below.

SSE3 optimized benchmark
The benchmark in mode I (SSE) is optimized for the use of SIMD instructions with 128 bits register and the SSE set up to version 3. Nearly every modern CPU has support for this mode.
