Can the NVIDIA GeForce RTX 3070 run Megatron-LM (355M)?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Megatron-LM (355M) on the NVIDIA GeForce RTX 3070

QuantFits?Max contextSpeedBeyond context
FP16 yes 79k 460.6-549 t/s ~41.1-49 (slow)
Q8 yes 84k 921.2-1097.9 t/s ~82.3-98 (slow)
Q4 yes 86k 1645.1-1960.6 t/s ~146.9-175.1 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA GeForce RTX 3070 run Megatron-LM (355M)?โ–ถ

Yes. At Q4 it generates ~1645.1-1960.6 tok/s and fits up to 86k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~146.9-175.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 86k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
