FP16 yes 200k 5309.1-6327.3 t/s ~221.2-263.6 (slow)
Q8 yes 201k 10618.2-12654.5 t/s ~442.4-527.3 (slow)
Q4 yes 201k 18961-22597.4 t/s ~790-941.6 (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 5080 run Theseus 6/768?โ–ถ

Yes. At Q4 it generates ~18961-22597.4 tok/s and fits up to 201k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~790-941.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 201k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
