Should you pick RTX 3090 for text-to-speech?

RTX 3090 has 24 GB VRAM. Whether it's the right fit for text-to-speech depends on your model size, expected QPS, and budget. Below is what we're seeing in production.

VRAM + model fit

RTX 3090 fits models up to ~17B parameters in BF16 comfortably with room for KV-cache. For text-to-speech specifically, you'll want to leave headroom for context length growth.
