32GB is worth it for 8GB+ DataFrames

Yes, it drastically reduces out-of-memory errors compared to 16GB, but it’s not foolproof.

Pandas keeps everything in RAM and often doubles or triples the raw data size due to copies, indexes, and intermediate transformations. An 8GB DataFrame can easily need 16–24GB of real memory. With 16GB you’re already in swap territory. With 32GB you have enough headroom for most operations on that size of data.

But “drastically reduces” isn’t “eliminates.” If you do heavy joins, groupbys, or keep multiple large DataFrames in memory, 32GB can still choke. You might need to switch to Dask, chunked processing, or careful memory management (e.g., using dtypes wisely, dropping columns you don’t need).

If you’re routinely hitting OOM with 32GB on datasets below 10GB, the problem is probably your code, not your RAM.
