NVIDIA RTX 4080 GPU: Specs, VRAM, Price & Benchmarks (2026)
The NVIDIA RTX 4080 (16GB GDDR6X) launched in 2022. 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 4080 rents from $0.331 per GPU per hour on Aquanode.
How much VRAM does the RTX 4080 have?
The RTX 4080 has 16GB GDDR6X, with 716.8 GB/s of peak memory bandwidth.
- VRAM: RTX 4080 16GB GDDR6X vs RTX 4090 24GB GDDR6X
- VRAM: RTX 4080 16GB GDDR6X vs RTX 5080 16GB GDDR7
What fits in 16GB GDDR6X of VRAM
| Model | Precision | Fits? |
|---|---|---|
| Llama 3 8B | FP8 | roughly 8GB. Fits with headroom for concurrency. |
| Mistral 7B | FP16 | ~14GB. Fits, tightly. |
| Mixtral 8x7B | INT4 | ~24GB. Does not fit on a single 16GB 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 4080 run?
Popular open models from small to frontier scale, with the memory each needs and how many RTX 4080 cards (16GB GDDR6X each) that takes.
| Model | As published | FP8 | INT4 |
|---|---|---|---|
| Qwen/Qwen3-8B 8.2B | BF16: ~18.3 GB, 2 GPUs | FP8: ~9.2 GB, 1 GPU | INT4: ~4.6 GB, 1 GPU |
| Qwen/Qwen2.5-14B-Instruct 14.8B | BF16: ~33 GB, 3 GPUs | FP8: ~16.5 GB, 2 GPUs | INT4: ~8.3 GB, 1 GPU |
| Qwen/Qwen3-32B 32.8B | BF16: ~73.2 GB, 5 GPUs | FP8: ~36.6 GB, 3 GPUs | INT4: ~18.3 GB, 2 GPUs |
| Qwen/Qwen-72B 72.3B | BF16: ~162 GB, 11 GPUs | FP8: ~80.8 GB, 6 GPUs | INT4: ~40.4 GB, 3 GPUs |
| MiniMaxAI/MiniMax-M2.7 228.7B | FP8: ~256 GB, 16 GPUs | – | INT4: ~128 GB, 8 GPUs |
| deepseek-ai/DeepSeek-R1 684.5B | FP8: ~765 GB, 48 GPUs | – | INT4: ~383 GB, 24 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 4080 VRAM calculator.

GPU Glossary: What is VRAM?, Tensor Cores, CUDA Cores, TFLOPS
RTX 4080 AI performance
Ada FP8 tensor cores and 16GB at a consumer hourly rate. 389.9 dense FP8 TFLOPS is real serving throughput for quantized 7-13B models, and it is usually cheaper per hour than anything with the same FP8 capability.
- Dense FP16/BF16 tensor throughput: 194.9 TFLOPS
- Dense FP8 tensor throughput: 389.9 TFLOPS
- Memory bandwidth: 716.8 GB/s
16GB with no ECC and no NVLink, on a 3-slot card. It is also slower than an RTX 5080 on every tensor path at the same capacity, so the only reason to pick it is price.
The cheapest RTX 4080 offer right now ($0.331/GPU/hr) is about 29% below the market median of $0.464/GPU/hr.

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 4080?
Live RTX 4080 rental prices currently range from $0.331 to $0.580 per GPU per hour, with a median of $0.464 per GPU per hour.
What's the cheapest RTX 4080 rate?
The lowest current RTX 4080 rate on Aquanode is $0.331 per GPU per hour in Germany.
How does the RTX 4080 compare to the RTX 4090?
VRAM: RTX 4080 16GB GDDR6X vs RTX 4090 24GB GDDR6X Memory bandwidth: 716.8 GB/s vs 1,008 GB/s On Aquanode right now, RTX 4080 starts at $0.331/GPU/hr against RTX 4090's $0.393/GPU/hr, about 16% less. See the full RTX 4080 vs RTX 4090 comparison for a shared-provider price breakdown.
How does the RTX 4080 compare to the RTX 5080?

What is the RTX 4080 good for?
Ada FP8 tensor cores and 16GB at a consumer hourly rate. 389.9 dense FP8 TFLOPS is real serving throughput for quantized 7-13B models, and it is usually cheaper per hour than anything with the same FP8 capability.
What are the RTX 4080's limitations?
16GB with no ECC and no NVLink, on a 3-slot card. It is also slower than an RTX 5080 on every tensor path at the same capacity, so the only reason to pick it is price.
Is renting cheaper than buying?
Renting avoids the upfront hardware cost and lets you match spend to actual usage. A rented RTX 4080 at $0.331/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 $1,199 (launch MSRP). Which is cheaper depends on how continuously you'd run it; short or bursty workloads usually favor renting.
How is the RTX 4080 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.
