Can the AMD Radeon RX 7800 XT run Prithvi WxC?
Yes — here's how fast and up to what context, with real measured numbers.
Prithvi WxC on the AMD Radeon RX 7800 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 132k | 85.5-104.5 t/s | ~5.5-6.7 (slow) |
| Q8 | yes | 167k | 170.9-208.9 t/s | ~11-13.4 (slow) |
| Q4 | yes | 182k | 305.2-373 t/s | ~19.6-23.9 (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 Prithvi WxC?▶
Yes. At Q4 it generates ~305.2-373 tok/s and fits up to 182k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~19.6-23.9 tok/s.
How much context fits?▶
At Q4, up to about 182k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
