Diferencias clave

• VRAM is the big one: 16GB on the ASUS vs 32GB on the ZOTAC. If you're training models or working with huge 3D scenes, the ZOTAC's extra memory is the whole ballgame.
• Power draw is wildly different: 150W TDP on the ASUS vs 575W on the ZOTAC. That's the difference between a modest 850W PSU and a beefy 1000W unit, plus a lot more heat in your room.
• Physical size matters: the ASUS is 304mm long and 2.5 slots, the ZOTAC is 330mm and 3.5 slots. The ZOTAC simply won't fit in many mid-tower cases without some planning.
• Raw compute favors the ZOTAC: 21,760 CUDA cores and a 512-bit bus vs 10,752 cores and 256-bit on the ASUS. PassMark shows it too, 38,958 vs 35,759.
• Real-world sentiment on the ASUS is solid but not perfect: owners love the 4K performance and cool temps around 67-68°C, but the price stings and one unit arrived dead. The ZOTAC has no sentiment data here, so you're buying on specs alone.
