- For General Use: CPython is often the best choice due to its compatibility and the vast ecosystem of libraries and tools. For Performance-Sensitive Applications: PyPy can be a better choice if your application can benefit from JIT compilation, especially if it is long-running and computationally intensive.

Sep 23, 2013 · Long-term evidence is showing that PyPy runs certain Python codes slower than CPython and this drawback seems to be rooted very deeply in PyPy. Secondly, the current version of PyPy consumes much more memory than CPython in a rather large set of cases.
Aug 19, 2021 · Brief reviews on popular Python compilers like Cython, PyPy, and the default Python interpreter CPython.
Differences between PyPy and CPython. This page documents the few differences and incompatibilities between the PyPy Python interpreter and CPython. Some of these differences are “by design”, since we think that there are cases in which the behaviour of CPython is buggy, and we do not want to copy bugs.
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.

The PyPy implementation is 16 times faster than the CPython implementation and about 3 times slower than the Cython implementation. This is fascinating since PyPy is running the exact same pure Python code as the CPython implementation – it shows the power of PyPy’s JIT compiler.
Mar 16, 2024 · Definition: PyPy is an alternative implementation of Python, featuring a Just-In-Time (JIT) compiler designed to execute Python code faster than CPython. Performance: PyPy can significantly outperform CPython on long-running programs due to its JIT compiler, which optimizes frequently executed code.
