Both models
i7-4702MQ and
i7-4720HQ 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 i7-4702MQ gets a score of
145.1 k points while the i7-4720HQ gets
132.3 k points.
Summarizing, the
i7-4702MQ is
1.1 times faster than the
i7-4720HQ. To get a proper comparison between both models, take a look to the data shown below.
