NVIDIA RTX 3080 GPU: Specs, VRAM, Price & Benchmarks (2026)
The NVIDIA RTX 3080 (10GB GDDR6X (a 12GB variant also ships)) launched in 2020. This guide covers its full specs, VRAM, SXM/PCIe differences where they apply, AI performance, and live per-GPU rental pricing on Aquanode.
Short answer on cost: the RTX 3080 rents from $0.176 per GPU per hour on Aquanode.
How much VRAM does the RTX 3080 have?
The RTX 3080 has 10GB GDDR6X (a 12GB variant also ships), with 760 GB/s of peak memory bandwidth.
- VRAM: RTX 3080 10GB GDDR6X (a 12GB variant also ships) vs RTX 3090 24GB GDDR6X
- VRAM: RTX 3080 10GB GDDR6X (a 12GB variant also ships) vs RTX 3070 8GB GDDR6
What fits in 10GB GDDR6X (a 12GB variant also ships) of VRAM
| Model | Precision | Fits? |
|---|---|---|
| Llama 3.2 3B | BF16 | roughly 6GB. Fits with room for a batch. |
| Llama 3 8B | INT4 | ~5-6GB. Fits comfortably. |
| Mistral 7B | BF16 | ~14GB. Does not fit on a single 10GB card. |
| Llama 3.1 70B | INT4 | ~35-40GB. Does not fit. |
Approximate, based on published parameter counts and standard bytes-per-parameter rules of thumb (FP16 ≈ 2 bytes/param, INT4 ≈ 0.5-0.6 bytes/param). Real footprint also depends on KV-cache size and framework overhead.
What can the RTX 3080 run?
Popular open models from small to frontier scale, with the memory each needs and how many RTX 3080 cards (10GB GDDR6X (a 12GB variant also ships) each) that takes.
| Model | As published | FP8 | INT4 |
|---|---|---|---|
| Qwen/Qwen3-8B 8.2B | BF16: ~18.3 GB, 2 GPUs | FP8: not supported | INT4: ~4.6 GB, 1 GPU |
| Qwen/Qwen2.5-14B-Instruct 14.8B | BF16: ~33 GB, 4 GPUs | FP8: not supported | INT4: ~8.3 GB, 1 GPU |
| Qwen/Qwen3-32B 32.8B | BF16: ~73.2 GB, 8 GPUs | FP8: not supported | INT4: ~18.3 GB, 2 GPUs |
| Qwen/Qwen-72B 72.3B | BF16: ~162 GB, 17 GPUs | FP8: not supported | INT4: ~40.4 GB, 5 GPUs |
| MiniMaxAI/MiniMax-M2.7 228.7B | FP8: not supported | – | INT4: ~128 GB, 13 GPUs |
| deepseek-ai/DeepSeek-R1 684.5B | FP8: not supported | – | INT4: ~383 GB, 39 GPUs |
Estimates: weights at the stated precision plus a flat 20% for KV cache and overhead, at a moderate context length. A dash means the precision is not offered for that model (it is already published at that size). INT4 needs a published quantized checkpoint. Open any model for a per-GPU breakdown, or use the RTX 3080 VRAM calculator.

RTX 3080 AI performance
760 GB/s of GDDR6X for very little money. For small-model inference where the bottleneck is memory bandwidth rather than capacity, it is one of the better throughput-per-dollar cards on this marketplace.
- Dense FP16/BF16 tensor throughput: 119 TFLOPS
- Memory bandwidth: 760 GB/s
10GB. That is the binding limit on almost everything: a 7B model at BF16 does not fit, so essentially all LLM work here has to be quantized. No FP8 (Ampere), no ECC, no NVLink.
RTX 3080 price: what does it cost?
Buying. $699 (launch MSRP).
Renting. The cheapest current on-demand rate for the RTX 3080 on Aquanode is $0.176/GPU/hr (no on-demand supply right now; this is the cheapest offer overall). Live rates range from $0.176 to $0.352 per GPU per hour, with a median of $0.176/GPU/hr. Billed by the offer's own terms; the table below shows every live rate.
| Region | $/GPU/hr | Available | VRAM | vCPU | RAM |

| Canada | $0.176 | 1 | 10 GB | 22 | 28 GB |
| Quebec, Ca | $0.345 | 2 | 12 GB | 24 | 31.5 GB |
RTX 3080 price history
Aquanode stores one snapshot of its GPU price index per UTC day. For the RTX 3080 that is 18 days so far, 2026-10-06 to 2026-10-31, so this is a short history, not a long-run trend. The lowest per-GPU rate went from $0.187 on 2026-10-06 to $0.176 on 2026-10-31.

How this price is calculated
All prices on this page are normalized to a per-GPU hourly rate using each offer's authoritative GPU count, so that raw price is divided by the number of GPUs it actually covers; some offers report price as already per-GPU, so those are used as-listed. An offer with a missing, zero, or invalid GPU count is excluded entirely rather than published at a guessed rate.
No offers were excluded from this snapshot for a missing or invalid price. No offers were dropped as price outliers in this snapshot.
Only the cheapest qualifying offer per provider is shown in the table above. This page regenerates at most once per hour.

How much does it cost to rent a RTX 3080?
Live RTX 3080 rental prices currently range from $0.176 to $0.352 per GPU per hour, with a median of $0.176 per GPU per hour.
What's the cheapest RTX 3080 rate?
The lowest current RTX 3080 rate on Aquanode is $0.176 per GPU per hour in Canada.
How does the RTX 3080 compare to the RTX 3090?
VRAM: RTX 3080 10GB GDDR6X (a 12GB variant also ships) vs RTX 3090 24GB GDDR6X Memory bandwidth: 760 GB/s vs 936 GB/s Dense FP16 tensor throughput: 119 TFLOPS vs 142 TFLOPS On Aquanode right now, RTX 3080 starts at $0.176/GPU/hr against RTX 3090's $0.286/GPU/hr, about 38% less.

How does the RTX 3080 compare to the RTX 3070?
VRAM: RTX 3080 10GB GDDR6X (a 12GB variant also ships) vs RTX 3070 8GB GDDR6 Memory bandwidth: 760 GB/s vs 448 GB/s Dense FP16 tensor throughput: 119 TFLOPS vs 81.3 TFLOPS On Aquanode right now, RTX 3070 starts at $0.132/GPU/hr against RTX 3080's $0.176/GPU/hr, about 25% less.

What is the RTX 3080 good for?
760 GB/s of GDDR6X for very little money. For small-model inference where the bottleneck is memory bandwidth rather than capacity, it is one of the better throughput-per-dollar cards on this marketplace.
What are the RTX 3080's limitations?
10GB. That is the binding limit on almost everything: a 7B model at BF16 does not fit, so essentially all LLM work here has to be quantized. No FP8 (Ampere), no ECC, no NVLink.
Is renting cheaper than buying?
Renting avoids the upfront hardware cost and lets you match spend to actual usage. A rented RTX 3080 at $0.176/hr only costs money while it's running, whereas buying ties up capital in hardware that keeps depreciating whether it's in use or not. Buying outright runs $699 (launch MSRP). Which is cheaper depends on how continuously you'd run it; short or bursty workloads usually favor renting.
How is the RTX 3080 price calculated?
All prices are normalized to a per-GPU hourly rate using each offer's authoritative GPU count, which the raw price is divided by; some offers report price as already per-GPU. Offers whose price can't be safely normalized, or whose rate is an extreme outlier against the rest of the market, are excluded.
