RTX 3080 VS RTX 4070 - FAQ
Which is cheaper to rent, RTX 3080 or RTX 4070?
By today's published on-demand rates: RTX 3080 starts at $0.030/GPU/hr (median $0.14, 8 providers) and RTX 4070 starts at $0.060/GPU/hr (median $0.41, 6 providers). The cheapest live listing is the RTX 3080 at QuickPod. Figures recompute from the panel on every refresh.
RTX 3080 or RTX 4070 - which should I rent?
RTX 3080: The card that defined pandemic-era GPU scarcity remains a catalog staple: fast GDDR6X bandwidth, Ampere tensor cores, and a 10-12 GB ceiling. RTX 4070: The RTX 4070 is Ada's efficient mid-ranger: 200 W, 12 GB, and enough tensor throughput for 7B-class serving. The side-by-side spec table and live price rows above give the full picture.
