Core i5-3437U vs Xeon E5-2651 v2
Description
Both models i5-3437U and E5-2651 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 i5-3437U gets a score of 30.5 k points while the E5-2651 v2 gets 426.2 k points.
Summarizing, the E5-2651 v2 is 14 times faster than the i5-3437U . To get a proper comparison between both models, take a look to the data shown below.
