Frequently Asked Questions

How much VRAM does T Pro IT 2.1 need?

T Pro IT 2.1 requires 66.2 GB of VRAM at BF16. Full 41K context adds up to 6.4 GB (72.5 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 32.8B × 16 bits ÷ 8 = 65.5 GB

KV Cache + Overhead 0.7 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead 7 GB (at full 41K context)

Can NVIDIA GeForce RTX 5090 run T Pro IT 2.1?

No — T Pro IT 2.1 requires at least 66.2 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.

Can I run T Pro IT 2.1 on a Mac?

T Pro IT 2.1 requires at least 66.2 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 T Pro IT 2.1 locally?

Yes — T Pro IT 2.1 can run locally on consumer hardware. At BF16 quantization it needs 66.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is T Pro IT 2.1?

At BF16, T Pro IT 2.1 can reach ~44 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: AMD Instinct MI300X5300 ÷ 66.2 × 0.55 = ~44 tok/s

Estimated speed at BF16 (66.2 GB)

~44 tok/s
~33 tok/s
~27 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
