L4 vs T4: Specs, VRAM & Price
Short answer: choose the L4 when 24 GB of VRAM is the gating requirement. Choose the T4 when 16 GB is enough for the workload and the lower hourly rate points that way.
The L4 has 24 GB of VRAM; the T4 has 16 GB.
You can rent both by the hour, no purchase required. L4 from $0.649/GPU/hr; T4 from $0.185/GPU/hr. The T4 is 72% cheaper at the entry rate.
L4
Good for inference and light fine-tuning workloads
T4
Good for inference workloads on older-generation hardware

L4 vs T4: common questions
Is the L4 or the T4 better for AI?
Short answer: choose the L4 when 24 GB of VRAM is the gating requirement. Choose the T4 when 16 GB is enough for the workload and the lower hourly rate points that way.
Is the L4 or the T4 cheaper to rent?
On Aquanode's live marketplace the L4 starts at $0.649/GPU/hr (median $0.649/GPU/hr) and the T4 starts at $0.185/GPU/hr (median $0.185/GPU/hr). The T4 is the cheaper of the two at the entry rate, by 72%.
What is the difference between the L4 and the T4?
The L4 has 24 GB of VRAM against the T4's 16 GB; the L4 is an Ada Lovelace part and the T4 is Turing (compute capability 8.9 vs 7.5); only the L4 supports BF16, FP8 compute. On price, the L4 lists from $0.649/GPU/hr and the T4 from $0.185/GPU/hr.
How widely available are the L4 and the T4?
The L4 is listed in 1 region and the T4 in 1 region right now.
How much does 1,000 GPU-hours cost on the L4 vs the T4?
At the lowest rates listed today, 1,000 GPU-hours costs $649 on the L4 and $185 on the T4, a difference of $464 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the L4 have compared to the T4?
The L4 has 24 GB of VRAM; the T4 has 16 GB.
Does the L4 or the T4 support NVLink?
Neither the L4 nor the T4 has a dedicated GPU-to-GPU interconnect.
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 L4 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.
