Frequently Asked Questions
- How much VRAM does T5gemma B B Ul2 IT need?
T5gemma B B Ul2 IT requires 1.3 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 591M × 16 bits ÷ 8 = 1.2 GB
KV Cache + Overhead ≈ 0.1 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
BF161.3 GB- Can I run T5gemma B B Ul2 IT on a Mac?
T5gemma B B Ul2 IT requires at least 1.3 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run T5gemma B B Ul2 IT locally?
Yes — T5gemma B B Ul2 IT can run locally on consumer hardware. At BF16 quantization it needs 1.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is T5gemma B B Ul2 IT?
At BF16, T5gemma B B Ul2 IT can reach ~3385 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~504 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 1.3 × 0.65 = ~4000 tok/s
Estimated speed at BF16 (1.3 GB)
~4000 tok/s~504 tok/s~4000 tok/s~3385 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
