RTX 3090 Ti vs RTX 4080S?

The RTX 4080S has more FP32 (about 50.9 vs 36.4 TFLOPS) but only 16 GB. The RTX 3090 Ti has 24 GB and more bandwidth (865 vs 600 GB/s), so it fits bigger models.

Which LLMs run best on 24 GB?

8B models in 16-bit, 14B at 8-bit and 30B–34B at 4-bit. 70B models need 48 GB or more even when quantized.

Does the RTX 3090 Ti support BF16?

Yes. Ampere (compute capability 8.6) supports BF16, the standard precision for current fine-tuning recipes.

How does Cloudj bill the RTX 3090 Ti?

Per minute from your account balance while it runs, at the price locked when you deploy, plus bandwidth per GB. A stopped instance is charged for storage only. There are no monthly GPU plans.

What you can run on the RTX 3090 Ti cloud GPU

Higher-bandwidth LLM inference

865 GB/s gives the RTX 3090 Ti the most bandwidth of any Ampere consumer card listed, for faster decoding.

Flux with LoRAs

24 GB holds Flux plus LoRAs and upscalers in a single ComfyUI graph.

Fine-tuning 7B–14B models

QLoRA and LoRA runs in BF16 with Unsloth fit comfortably in 24 GB.

Sustained rendering

A 450 W power limit keeps clocks high for long Cycles or OctaneRender jobs.

Is the RTX 3090 Ti the right GPU for your workload?

The RTX 3090 Ti is a practical choice for developers and researchers who need 24 GB of VRAM on an Ampere consumer card for inference or moderate training tasks. Choose a GPU with lower memory if you only run small models, or step up to a workstation or datacenter GPU if your workloads require more than 24 GB of VRAM or newer architectural features.
