FLOPS by Precision

What actually differs

Both launched in 2020, the Radeon RX 6800 XT on RDNA 2 and the GeForce RTX 3070 on Ampere.

The Radeon RX 6800 XT carries 8 GB more memory (16 GB against 8 GB), so larger models fit on one GPU before you shard. Bandwidth is 512 GB/s against 448 GB/s, which sets the ceiling on decode speed.

Power is 300 W against 220 W, and at FP32 the GeForce RTX 3070 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.

Frequently asked questions

Is the Radeon RX 6800 XT faster than the GeForce RTX 3070?

They are close on paper: both deliver about 41 TFLOPS of dense FP16 throughput. Memory, bandwidth, and power are the deciding differences.

Which should you choose, the Radeon RX 6800 XT or the GeForce RTX 3070?

On raw FP16 throughput the Radeon RX 6800 XT and the GeForce RTX 3070 are level, so the decision rests on memory, power and price. Choose the Radeon RX 6800 XT when the model has to fit on one GPU: it carries 8 GB more memory. The GeForce RTX 3070 draws 80 W less power, which matters in an air-cooled or power-capped rack.

Which has more memory, the Radeon RX 6800 XT or the GeForce RTX 3070?

The Radeon RX 6800 XT carries 16 GB of memory versus 8 GB for the GeForce RTX 3070. Memory bandwidth is 512 GB/s for the Radeon RX 6800 XT and 448 GB/s for the GeForce RTX 3070.

How much power do the Radeon RX 6800 XT and the GeForce RTX 3070 draw?

The Radeon RX 6800 XT is rated at 300 W TDP and the GeForce RTX 3070 at 220 W. On FP32 throughput per watt, the GeForce RTX 3070 is the more efficient part.
