RTX A4000 vs T4: Specs, VRAM & Price
Short answer: choose the RTX A4000 when you want the lower hourly rate and the specs are otherwise a wash. Choose the T4 when T4 pricing or availability works better where you're deploying.
Both the RTX A4000 and the T4 ship with 16 GB of VRAM.
You can rent both by the hour, no purchase required. RTX A4000 from $0.167/GPU/hr; T4 from $0.185/GPU/hr. The RTX A4000 is 10% cheaper at the entry rate.

RTX A4000 vs T4: common questions
Is the RTX A4000 or the T4 better for AI?
Short answer: choose the RTX A4000 when you want the lower hourly rate and the specs are otherwise a wash. Choose the T4 when T4 pricing or availability works better where you're deploying.
Is the RTX A4000 or the T4 cheaper to rent?
On Aquanode's live marketplace the RTX A4000 starts at $0.167/GPU/hr (median $0.187/GPU/hr) and the T4 starts at $0.185/GPU/hr (median $0.185/GPU/hr). The RTX A4000 is the cheaper of the two at the entry rate, by 10%.
What is the difference between the RTX A4000 and the T4?
Both cards report 16 GB of VRAM; the RTX A4000 is an Ampere part and the T4 is Turing (compute capability 8.6 vs 7.5); only the RTX A4000 supports BF16 compute. On price, the RTX A4000 lists from $0.167/GPU/hr and the T4 from $0.185/GPU/hr.
How widely available are the RTX A4000 and the T4?
The RTX A4000 is listed in 2 regions and the T4 in 1 region right now.
How much does 1,000 GPU-hours cost on the RTX A4000 vs the T4?
At the lowest rates listed today, 1,000 GPU-hours costs $167 on the RTX A4000 and $185 on the T4, a difference of $18 for the same runtime. Rates are per GPU per hour and update hourly.
How much VRAM does the RTX A4000 have compared to the T4?
Both the RTX A4000 and the T4 ship with 16 GB of VRAM.
Does the RTX A4000 or the T4 support NVLink?
Neither the RTX A4000 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 RTX A4000 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.
