RTX 3070 vs T4: Specs, VRAM & Price
Short answer: choose the T4 when 16 GB of VRAM is the gating requirement. Choose the RTX 3070 when 8 GB is enough for the workload and the lower hourly rate points that way.
The RTX 3070 has 8 GB of VRAM; the T4 has 16 GB.
You can rent both by the hour, no purchase required. RTX 3070 from $0.143/GPU/hr; T4 from $0.185/GPU/hr. The RTX 3070 is 23% cheaper at the entry rate.
RTX 3070

RTX 3070 vs T4: common questions
Is the RTX 3070 or the T4 better for AI?
Short answer: choose the T4 when 16 GB of VRAM is the gating requirement. Choose the RTX 3070 when 8 GB is enough for the workload and the lower hourly rate points that way.
Is the RTX 3070 or the T4 cheaper to rent?
On Aquanode's live marketplace the RTX 3070 starts at $0.143/GPU/hr (median $0.143/GPU/hr) and the T4 starts at $0.185/GPU/hr (median $0.185/GPU/hr). The RTX 3070 is the cheaper of the two at the entry rate, by 23%.
What is the difference between the RTX 3070 and the T4?
The RTX 3070 has 8 GB of VRAM against the T4's 16 GB; the RTX 3070 is an Ampere part and the T4 is Turing (compute capability 8.6 vs 7.5); only the RTX 3070 supports BF16 compute. On price, the RTX 3070 lists from $0.143/GPU/hr and the T4 from $0.185/GPU/hr.
How widely available are the RTX 3070 and the T4?
The RTX 3070 is listed in 1 region and the T4 in 1 region right now.
How much does 1,000 GPU-hours cost on the RTX 3070 vs the T4?
At the lowest rates listed today, 1,000 GPU-hours costs $143 on the RTX 3070 and $185 on the T4, a difference of $42 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the RTX 3070 have compared to the T4?
The RTX 3070 has 8 GB of VRAM; the T4 has 16 GB.
Does the RTX 3070 or the T4 support NVLink?

How this comparison is calculated
Every price is normalized to a per-GPU hourly rate using the same pipeline as every other pricing surface on Aquanode, and only the cheapest qualifying offer per provider is shown. A dash means that provider does not currently list that GPU.
Architecture, compute capability and supported precisions come from each vendor's published datasheet for that generation, not from the marketplace feed. This page regenerates at most once per hour.
Memory bandwidth, tensor TFLOPS, NVLink/interconnect and max board power are the same verified-from-datasheet figures shown on each model's own RTX 3070 page and T4 page, which link the primary vendor source for that model. A dash here means Aquanode hasn't verified that figure from a primary source yet, never a guess.
