RTX 3090 Ti vs RTX 4080S?

I-RTX 4080S ine-FP32 eningi (cishe 50.9 vs 36.4 TFLOPS) kodwa ingu-16 GB kuphela. I-RTX 3090 Ti ine-24 GB kanye ne-bandwidth ethe xaxa (865 vs 600 GB/s), ngakho-ke ithwala amamodeli amakhulu.

Yimaphi ama-LLM asebenza kahle kakhulu ku-24 GB?

Amamodeli e-8B ku-16-bit, 14B ku-8-bit kanye ne-30B–34B ku-4-bit. Amamodeli e-70B adinga i-48 GB noma ngaphezulu ngisho nalapho enziwe quantized.

Ingabe i-RTX 3090 Ti iyayisekela i-BF16?

Yebo. I-Ampere (compute capability 8.6) iyayisekela i-BF16, okuwukunemba okujwayelekile kwezindlela zokulungisa kahle zamanje.

I-Cloudj iyikhokhisa kanjani i-RTX 3090 Ti?

Ngehora ngenkathi isebenza, kusukela kubhalansi ye-akhawunti yakho, noma ngomjikelezo wanyanga zonke kuya kowonyaka nesaphulelo esiboniswa ngaphambi kokukhokha.

Qasha i-GPU ye-NVIDIA RTX 3090 Ti ene-24 GB VRAM

Qasha amaseva e-cloud GPU e-RTX 3090 Ti ngehora ku-Cloudj: 24 GB VRAM ku-NVIDIA Ampere enecishe ibe ngu-36.4 TFLOPS FP32 kanye ne-865 GB/s ye-memory bandwidth. Ikhadi le-Ampere labathengi elishesha kakhulu ohlwini lwethu lilungele abathuthukisi be-AI nabaculi abasebenzisa i-Flux, ama-LLM esigaba se-30B ku-4-bit kanye nokulungisa kahle kwe-QLoRA emkhawulweni wamandla ongu-450 W. Khetha ithempulethi ye-ComfyUI, vLLM noma Unsloth bese uxhuma nge-SSH.
