PyPy is a reimplementation of Python in Python, using advanced techniques to try to attain better performance than CPython. Many years of hard work have finally paid off. Our speed results often beat CPython, ranging from being slightly slower, to speedups of up to 2x on real application code, to speedups of up to 10x on small benchmarks.
Mar 16, 2024 · CPython interprets bytecode, whereas PyPy uses JIT compilation to translate Python code into machine code dynamically, aiming for faster execution. Performance: PyPy often provides significant performance improvements over CPython in long-running applications due to JIT compilation.

Talking about CPython, it is the default implementation of Python specifications. It comes with the python distribution itself and interprets the python programs for the machine. Given that it is the default implementation of Python, whenever Python is upgraded with new features, language developers upgrade the CPython version as well and include i...
Cython is a separate compiler that can understand both Python and C specifications. It is more like a superset of Python compiler and allows you to work with Python and C together in a single project. How does this help? Alright, so, Cython compiles the hybrid python and C code into a very efficient C program which in turn can be compiled to the ma...
PyPy works on the Just in Timecompilation principle. Like interpreters, JIT compilers also pick up the raw code but turns the code into efficient machine code just before the execution. There are a lot of optimization techniques involved in JIT compilers and that makes JIT compilers work much faster than the raw interpreters. PyPy also consumes les...
While there are multiple compilers, they all try to solve different problems and work differently. Looking at the statistics and usage, Cython seems to be the leader in the game and provides the fastest execution speeds, has a great community, good documentation, and is a potential candidate to get included in the default python distribution itself...
Based on different benchmarks done by the PyPy team it seems that it is 4.7X faster than CPython ( https://speed.pypy.org/ ). The crazy thing about it is that you don’t need to rewrite the code. The only thing that needs to be done is to replace CPython with PyPy.

Dec 12, 2021 · PyPy is a Python implementation written in Python (specifically RPython) and is a replacement for CPython. PyPy's main utility is that it is really fast, in fact, it claims to be almost 5x faster than CPython. However, PyPy can run most Python code except for when the code depends on CPython extensions which results in either inability to run ...
