HOW TO CHOOSE
RTX 3070 vs RTX 4070
The 4070's 12 GB and Ada tensor cores open workloads the 3070's 8 GB excludes. Worth a real premium for LLM work.
RTX 4070 vs RTX 3070
The 3070's 8 GB excludes even comfortable 7B serving with context. The 4070's 12 GB and newer tensor cores are worth a real premium.
Workload fit
RTX 3070: development, 7b inference, fine-tuning. RTX 4070: 7b-class inference, development, 13b-class models.
RTX 3070 VS RTX 4070 - FAQ
Which is cheaper to rent, RTX 3070 or RTX 4070?
By today's published on-demand rates: RTX 3070 starts at $0.020/GPU/hr (median $2.25, 8 providers) and RTX 4070 starts at $0.060/GPU/hr (median $0.41, 6 providers). The cheapest live listing is the RTX 3070 at QuickPod. Figures recompute from the panel on every refresh.
RTX 3070 or RTX 4070 - which should I rent?
RTX 3070: The 3070 was Ampere's mainstream hit, but its 8 GB of GDDR6 defines it in 2026: enough for small dev work and 7B models at tight quantization, not enough for comfortable serving. 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.
Where can I rent RTX 3070 and RTX 4070?
8 providers publish RTX 3070 rates and 6 publish RTX 4070 rates on Compute Cafe. Every row links to the provider's own published price - committed-use and reserved rates are excluded.
