Core i3-3240 vs Xeon E5-2651 v2
Description
Both models i3-3240 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 i3-3240 gets a score of 49.7 k points while the E5-2651 v2 gets 426.2 k points.
Summarizing, the E5-2651 v2 is 8.6 times faster than the i3-3240 . To get a proper comparison between both models, take a look to the data shown below.
