Core E5-2620 v3 vs Xeon E3-1220 v3
Description
Both models E5-2620 v3 and E3-1220 v3 are based on Haswell architecture.
"Haswell is known as fourth-generation core too. It uses 22nm Tri-Gate FinFET (non-planar, ""3D"") technology. It includes four arithmetic logic unit (ALU) and three address generation unit (AGU). This generation is able to run Advanced Vector Extensions 2 (AVX2) instruction set among BMI1, BMI2, ABM and FMA3. At this time, Intel used new sockets: LGA 1150 for desktops and BGA1364 for the mobile CPUs."
Using the multithread performance as a reference, the E5-2620 v3 gets a score of 358 k points while the E3-1220 v3 gets 140.8 k points.
Summarizing, the E5-2620 v3 is 2.5 times faster than the E3-1220 v3 . To get a proper comparison between both models, take a look to the data shown below.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.
Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.
If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
