// RUN โ€” FITS

Can the AMD Radeon RX 7800 XT run MatterSim (M3GNet - MatterSim-v1.0.0-5M)?

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

MatterSim (M3GNet - MatterSim-v1.0.0-5M) on the AMD Radeon RX 7800 XT

FP16 yes 202k 43680-53386.7 t/s ~2800-3422.2 (slow)
Q8 yes 202k 87360-106773.3 t/s ~5600-6844.4 (slow)
Q4 yes 202k 156000-190666.7 t/s ~10000-12222.2 (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 AMD Radeon RX 7800 XT run MatterSim (M3GNet - MatterSim-v1.0.0-5M)?โ–ถ

Yes. At Q4 it generates ~156000-190666.7 tok/s and fits up to 202k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~10000-12222.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 202k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
