Can NVIDIA GeForce RTX 4060 run scGPT?

50M parameter Scientific Computing model on 8GB GDDR6

Yes — runs at 8-bit quantization
SpeedFast inference, near-native speed
QualityNear-lossless — virtually identical to FP16

VRAM Requirements

scGPT is a 50M parameter model. At full precision (FP16), it requires 12GB of VRAM. Your NVIDIA GeForce RTX 4060 has 8GB, so you'll need to quantize it to 8-bit (Q8) to fit.

FP16 (Full Precision)12GB (need 4GB more)

Maximum quality, no quantization

Q8 (8-bit)8GB (0GB free)

Near-lossless, ~50% size reduction

Q4 (4-bit)4GB (4GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 8GB GDDR6 at 272 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

scGPT on NVIDIA GeForce RTX 4060 handles medium single-cell datasets (10K-50K cells) well. Fine-tuning and inference for cell type annotation and gene network analysis run smoothly. For very large datasets (100K+ cells), consider batching or a GPU with more VRAM.

How to Set It Up

Step 1: Set up Python environment

conda create -n scicomp python=3.10 && conda activate scicomp

A clean Conda environment avoids dependency conflicts. Python 3.10 is recommended for most scientific computing tools.

Step 2: Install scGPT

pip install scgpt

Foundation model for single-cell RNA-seq. Requires scanpy and anndata for data handling.

Step 3: Load pre-trained model

Download pre-trained checkpoints from the scGPT GitHub repository. Fine-tune on your dataset for cell type annotation, perturbation prediction, or batch integration.

Step 4: Verify GPU is being used

nvidia-smi

Check that VRAM usage increases when the model loads. You should see ~8GB used.

About scGPT

Foundation model for single-cell RNA-seq analysis. Fine-tune for cell type annotation, gene perturbation prediction, multi-batch integration, and multi-omics analysis. VRAM scales with dataset size — 100K+ cells need 12GB, smaller datasets fit on 4-8GB. Replaces traditional pipelines like Scanpy for many tasks.
