Nvidia will release the RTX 3070 available on October 29. Samples have been seeded and along with it, NVIDIA provides a reviewers guide, almost the complete 'Reviewer's Guide' for the RTX 3070 Founders Edition has been published by Videocardz.

Nvidia mainly emphasizes what performance the card should be able to provide so that reviewers know how the card being tested should perform. The green team claims that in 'various' DirectX 12 and Vulkan games, it is on average 60% faster than the RTX 2070 (non-Super) and as fast as or faster than the RTX 2080 Ti. That would apply to both games with and without ray tracing. Nvidia also says it now officially supports av1, which should generally provide 50% to 55% better performance compared to h.264. At the same time, the image quality of this open standard must also be better than both h.264, h.265 (hecv) and vp9.
