At the silicon level, these cards are built from the same cloth: identical Blackwell architecture, the same 5nm process node, and an equal transistor count of 21.9 billion. Their 180W TDP and PCIe 5.0 interface are also shared, meaning power supply requirements and motherboard compatibility are equivalent. For buyers concerned about platform fit or electricity costs, neither card demands more than the other.
Where the two diverge meaningfully is physical footprint. The Asus Dual measures 229 × 120 mm, while the TUF Gaming OC Edition is considerably larger at 302 × 133.5 mm — a difference of 73mm in length and 13.5mm in height. That gap matters in compact or mid-tower cases where clearance between the GPU and drive bays, front panel, or other components can be tight. The Dual's smaller chassis makes it the more versatile option for space-constrained builds, while the TUF's larger PCB and cooler shroud likely accommodate a more substantial cooling solution — though thermal performance itself is not specified in this group.
For general build planning, the Asus Dual holds a clear advantage in this group due to its significantly more compact dimensions, making it the better fit for smaller cases or tightly packed systems. Users with full-tower or spacious mid-tower builds will find either card accommodates without issue, leaving size as a non-factor — but for anyone working within tighter constraints, the Dual's footprint is a practical win.
