Is it?
Modern hardware has better IPC and, late 2000s hardware don't stand up as well as they used to.
Minetest is more dependent on CPU than GPU due to Irrlicht doing all mesh operations in RAM, not VRAM.
This is why pre AMD Ryzen CPUs are terrible with Minetest specifically. This also extends to Intel Pentium (recent LGA models lower than the i3) and Celeron / Atom series.
I would potentially have even better performance if I was using a native Linux machine. However, due to poor nonfree and free drivers the gain would be worthless overall. AMD RX 480 drivers are bad in both Radeon and fglrx.
I remember RBA complaining about Irrlicht not using the GPU for meshes in memory. VBOs help, but not a lot overall due to Minetests poor occlusion culling.
Addendum: As Minetest isn't multi threaded, AMDs "moar cores" meme doesn't apply. This also goes for HT Intel CPUs too.

Did you read first message at all? It is not about AMD or anything, it is about occlusion culling inefficiency.

It sounds like we have two issues - broken occlusion culling, and using the CPU/RAM for things that should be done with the GPU/VRAM?
