The parameters of the previous generation Pi 3 is a quad-core Cortex A53 CPU, and the memory is only 1GB. Looking at these two aspects alone, the performance of the Pi 4 has indeed improved a lot.
So how good is the performance of the Raspberry Pi 4? Some netizens conducted a benchmark. He ran the scientific computing software Mathematica 12 and 11.3 versions on Raspberry Pi 4 and 3 respectively for testing.
Mathematica, together with MATLAB and Maple, is known as the three major mathematical software. It combines numerical and symbolic computing engines, graphics systems, programming languages, text systems and advanced connections with other applications. Mathematica is the most powerful general-purpose computing system in the world and one of the most widely used mathematical software today. Its release in 1988 marked the beginning of modern scientific computing and had a profound impact on how computers are used in science and other fields.
The test results are that running Mathematica 12 on a Raspberry Pi 4 is 2x faster than running Mathematica 11.3 on a Raspberry Pi 3.
Because the benchmarks are different and there are no more specific relevant test descriptions, some people say that it is difficult to determine whether such performance advantages are brought about by improvements at the operating system, hardware or software level. The person who replied to him firmly believed that the main reason was the hardware. Performance improvements, that is, the capabilities of the Raspberry Pi 4, he explained that Mathematica 12 offers many new features that are not relevant to the benchmark set used here.
