Basically this article does the similar thing with BlazingSQL. Actually both are built on top of the cuDF project. The difference is that TiDB is an HTAP database and this article describes how we empower TiDB’s analytical processing by leveraging a GPU.

And the comparison is between TiDB running on a GPU and a CPU. No other database is involved in this comparison, and this may come in the future once the productionizing of this project is done.
