RTX 6000Ada vs RTX A6000: FAQ
Deeper reading: H100 vs H200 vs B200, RTX 4090 vs RTX 5090, how cloud GPU pricing works.
Is the RTX 6000Ada faster than the RTX A6000?
On dense FP16 tensor throughput the RTX 6000Ada leads by about 2.3× (364 vs 155 TFLOPS). Memory bandwidth matters as much for inference: RTX 6000Ada 960 GB/s vs RTX A6000 768 GB/s.
Which is cheaper to rent, the RTX 6000Ada or the RTX A6000?
The RTX A6000: $0.281/hr on-demand versus $0.513/hr — 45% less. Interruptible rates are $0.256 (RTX 6000Ada) and $0.140 (RTX A6000). Per TFLOP-hour the better value is the RTX 6000Ada.
Which has more VRAM and what does that change?
The RTX 6000Ada has 48 GB versus 48 GB. In LLM terms that is roughly a 14B FP16 model (or ~72B in 4-bit) on one card against 14B FP16 (~72B 4-bit). If the model does not fit, speed is irrelevant.
