Alibaba dropped Wan 2.2 14B under Apache 2.0 this May, and ComfyUI integration landed within days. The early numbers are interesting — Wan 2.2 is lighter than HunyuanVideo at comparable resolutions, which finally puts open-source video generation in reach of 16GB cards (with caveats). The Apache 2.0 license also means commercial use is fine, so this isn't just a tech demo. It's the model people are actually shipping social content with right now.

Quick answer: The RTX 4090 24GB is the best local pick for Wan 2.2 14B at FP16, while the RTX 4070 Ti Super 16GB handles int8/Q4 quants comfortably. If you want headroom for 5-second 720p clips at full precision without offload tricks, go RTX 5090.

Who this is for

You want to run Wan 2.2 locally — image-to-video, text-to-video, or short loops for social content — and you're tired of cloud queues and per-minute billing. This guide assumes you have ComfyUI installed (or are willing to), and want hard VRAM numbers instead of marketing-speak. If you're brand new to AI video, start with our best GPU for AI video primer first, then come back here once you've narrowed it to Wan.

VRAM requirements for Wan 2.2

Wan 2.2 ships in two flavors right now: the headline 14B model and a leaner 5B variant. The 5B is dramatically more forgiving on VRAM, but quality drops are noticeable — texture stability and prompt adherence both take a hit.

Variant + Quant	Minimum VRAM	Comfortable VRAM	Resolution Tested
Wan 2.2 14B FP16	24GB	28-32GB	720p, 5-sec
Wan 2.2 14B int8	16GB	20GB	720p, 5-sec
Wan 2.2 14B Q4	12GB	16GB	480p, 3-sec
Wan 2.2 5B FP16	12GB	16GB	720p, 5-sec
Wan 2.2 5B int8	8GB	12GB	480p, 5-sec

In our experience running both, the 14B at int8 on a 16GB card is the practical floor for results you'd actually post. Q4 on 12GB works, but artifacts creep in fast on motion-heavy scenes — faces deform mid-motion, text in backgrounds smears, and complex camera movements fall apart. A second factor most VRAM tables ignore: context length. Wan 2.2 scales VRAM roughly linearly with clip duration. A 5-second clip is the tested baseline; pushing to 8-10 seconds adds 30-50% more VRAM at the same resolution.

Generation times per GPU (Wan 2.2 14B)

Numbers below are community-aggregated estimates from ComfyUI Wan 2.2 workflows in early May 2026. Treat them as ballparks — sampler choice, step count, and motion complexity move these meaningfully.

GPU	VRAM	5-sec 480p (int8)	5-sec 720p (int8)	5-sec 720p (FP16)
RTX 5090	32GB	~2 min	~5 min	~7 min
RTX 4090	24GB	~3 min	~8 min	~12 min (tight)
RTX 3090	24GB	~5 min	~13 min	~19 min
RTX 5080	16GB	~4 min	~10 min	offload only
RTX 5070 Ti	16GB	~5 min	~12 min	offload only
RTX 4070 Ti Super	16GB	~6 min	~14 min	offload only
RTX 4060 Ti 16GB	16GB	~10 min	~24 min	not recommended
RTX 3060 12GB	12GB	~14 min (Q4)	not recommended	no

The 4060 Ti 16GB row is the most surprising — it technically fits Wan 2.2 14B int8, but the 128-bit memory bus chokes throughput. Bandwidth matters more than raw VRAM once you clear the minimum.

Best GPU picks for Wan 2.2

RTX 5090 — fastest local option

32GB of GDDR7 and ~1.8TB/s of memory bandwidth is overkill for Wan 2.2 5B and exactly right for 14B at FP16. If you're doing batch generation or planning to train LoRAs on Wan checkpoints, the headroom matters. At ~$2,000 it's not cheap, but it's the only consumer card that runs the 14B comfortably at FP16 without quantization compromises. We recommend against this card for anyone generating fewer than 20 clips a week — the marginal speed gain over a 4090 isn't worth $400 unless you're rendering daily.

RTX 4090 — best value for serious local use

24GB hits the Wan 2.2 14B FP16 minimum and breezes through int8. Generation times are roughly 1.7x slower than the 5090, which is the right trade for a $400 price gap. This is our default recommendation for anyone generating video weekly. We also flag it across our ComfyUI buying guide for the same reasons — it's the card that ages best across video, image, and LoRA training.

RTX 4070 Ti Super — the 16GB sweet spot

At ~$700, this is the cheapest card we'd buy specifically for Wan 2.2. 16GB handles 14B int8 cleanly at 720p, and the memory bandwidth (672 GB/s) keeps generation times sane. The RTX 5070 Ti is roughly equivalent at ~$750 — pick whichever is in stock.

RTX 3090 — used market value play

If you can find one at ~$700 used and trust the seller, 24GB GDDR6X runs Wan 2.2 14B at FP16. Generation is meaningfully slower than the 4090 (memory bandwidth gap is real — 936 GB/s vs 1008 GB/s plus the architectural gap), but the dollar-per-VRAM math is hard to beat for hobby use. Watch out for ex-mining cards: high hours don't kill 3090s outright, but thermal pads on the backside VRAM degrade and need replacing. Budget another $30 and an afternoon for that if you go used.

Don't bother: RTX 4060 Ti 16GB and below

This is the contrarian take. On paper, the 4060 Ti 16GB looks like a Wan 2.2 bargain. In practice, the 128-bit bus turns generation into a slideshow — a 720p int8 clip that takes 8 minutes on a 4090 takes 24 minutes here. Spend the extra $300 on a 4070 Ti Super and stop suffering. The RTX 3060 12GB is fine for Wan 2.2 5B at low resolution, but the 14B model isn't really its job.

Which GPU should YOU buy?

Generating Wan 2.2 daily, want max headroom? RTX 5090 32GB — FP16, no quantization, room for batches.
Weekly Wan 2.2 user, want best dollar-per-frame? RTX 4090 24GB — runs everything Wan ships at FP16 or int8.
First serious AI video build, $700 budget? RTX 4070 Ti Super 16GB — int8 14B is your sweet spot.
Already have a 3090? You're fine. Don't upgrade unless you're doing this professionally.
Stuck with 12GB? Use Wan 2.2 5B or Q4 14B at 480p — and consider cloud for anything you'd publish.
Training Wan LoRAs or fine-tuning? Skip consumer cards. See our AI research GPU guide — for research workloads on diffusion video models you want 48GB+ (RTX 6000 Ada or rented H100s), full stop.

Cloud is still reasonable for Wan 2.2

Wan 2.2 14B at FP16 on an A100 or H100 takes 3-5 minutes per 5-second 720p clip. At RunPod's spot pricing, that's roughly $0.20-0.40 per finished clip. If you generate fewer than ~50 clips a month, you'll never break even on a 4090 purchase. Power draw also matters — a 4090 pulls 350-450W during video generation, which adds up on a metered electric bill. Cloud GPUs externalize that cost. The other underrated cloud benefit: H100s with NVLink let you run Wan 2.2 14B at FP16 with 10-second clips, which no consumer card can match yet.

For high-volume daily use, local pays back inside 6 months. For experimentation, rent.

Common mistakes to avoid

Treating Wan 2.2 like HunyuanVideo. Wan is lighter — you don't always need 24GB. See our HunyuanVideo GPU breakdown for the contrast. Picking your GPU by the wrong model's requirements costs you ~$400-600.
Skipping int8 quantization on a 16GB card. ComfyUI's GGUF nodes for Wan 2.2 are stable as of May 2026. Use them. FP16 on 16GB will OOM on anything past 3 seconds.
Buying a 4060 Ti 16GB for the VRAM number. Memory bandwidth is the real bottleneck for video diffusion. The 4070 Ti Super is night-and-day faster despite the same VRAM.
Ignoring storage. Wan 2.2 14B FP16 weights are ~28GB on disk. Add ComfyUI, LoRAs, and output clips and you'll fill a 1TB SSD inside a month of active use.

Final verdict

Use case	Recommendation	Why
Maximum local performance	RTX 5090 32GB	FP16 14B with batch headroom
Best value for serious users	RTX 4090 24GB	FP16 14B at ~$400 less than 5090
Budget local entry	RTX 4070 Ti Super 16GB	int8 14B sweet spot at ~$700
Used market play	RTX 3090 24GB	FP16 14B if priced right
Hobby / 5B only	RTX 3060 12GB	Wan 2.2 5B at 480p, that's the ceiling
Occasional use	Cloud (RunPod / Vast.ai)	Cheaper than hardware under ~50 clips/month

For Wan 2.2 specifically, the RTX 4090 at 24GB is the GPU we'd buy with our own money today — fast enough at FP16, comfortable at int8, and priced where the math still works for serious local users without forcing a $2,000 commitment to the 5090 tier.
