Core i7-4500U vs i3-4170


Description
Both models i7-4500U and i3-4170 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 i7-4500U gets a score of 64.5 k points while the i3-4170 gets 92.7 k points.

Summarizing, the i3-4170 is 1.4 times faster than the i7-4500U . To get a proper comparison between both models, take a look to the data shown below.

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs

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.
