RTX 3090 vs RTX 4090: is the newer card worth it?

Both have 24 GB. The RTX 4090 is listed at about 81.4 TFLOPS vs 35.4 TFLOPS here, so it is much faster for compute; bandwidth is close (879 vs 805 GB/s). The RTX 3090 is the pick when the job fits and the live price is lower.

Can the RTX 3090 fine-tune a 13B model?

Yes with QLoRA. 13B at 4-bit takes about 7–8 GB, leaving room for adapters and activations in 24 GB.

RTX 3090 vs RTX 3090 Ti?

Very close: both 24 GB, with the Ti listed at 36.4 TFLOPS and 865 GB/s versus 35.4 TFLOPS and 805 GB/s. Pick whichever is available at the better price.

How do I start an RTX 3090 on Cloudj?

Choose a template, pick a live RTX 3090 configuration (filter by country if location matters), select your SSH key and confirm the price. Then connect over SSH with the host and port shown on the instance page.

Is the RTX 3090 the right GPU for your workload?

The RTX 3090 suits developers and researchers who need 24 GB of VRAM for memory-intensive tasks on a consumer-segment Ampere card. Choose a smaller GPU for lightweight inference that requires less memory, or step up to a workstation or datacenter GPU if your models exceed 24 GB of VRAM or require newer architecture features.
