There are a few (mostly Bitcoin forks), and you can probably make some profit mining them, but they are not big enough to have a significant impact on the global demand for GPUs.

At this point, most crypto projects with any real traction (with the obvious exception of Bitcoin) are either ERC-20 tokens running on Ethereum, or other PoS chains that claim to be better than Ethereum (i.e. Cardano).

Bitcoin isn't mined with GPUs anymore.
