More benchmark data about the GeForce RTX 3080 has leaked ahead of the card's official release next week. Based on initial findings, NVIDIA's US$1,499 card only just outperforms the US$699 RTX 3080 in many triple-A titles and by a margin as slim as 4.7%. The RTX 3090 fares better in synthetic benchmarks, but it can only achieve a lead of 10-20% for over twice the price of the RTX 3080.
