据英伟达官方信誓旦旦地宣称，RTX5070的游戏性能竟能与高端的RTX4090相媲美，可价格却仅仅是后者的三分之一。此消息如一颗重磅炸弹，瞬间在PC游戏圈炸开了锅。不少已早早入手RTX4090的玩家听闻后，难免心生遗憾。玩家群体中讨论声此起彼伏，争议不断。
近日，英伟达的一名开发者出面澄清，暗示若未启用DLSS 4的多帧生成功能，RTX 5070难以超越RTX 4090。
自RTX 5070面世以来，各大社交媒体平台上不断有玩家提出疑问：一张售价549美元的显卡，真的能与一张1499美元的显卡性能相当吗?虽然答案看似显而易见，但AI技术的运用却令人咋舌。DLSS 4多帧生成技术所产生的虚拟帧，是造成两者性能看似接近的主要因素。
外媒The Verge对此进行了详尽报道，并专访了英伟达的高级技术产品经理Lars Weinand。他解释说，尽管借助神经渲染和DLSS 4技术，RTX 5070能够接近RTX 4090的性能水平，但并不意味着它能在所有配置和方面都超越RTX 4090。
Weinand强调：“通过神经渲染和DLSS 4，我们可以达到RTX 4090级别的性能。但这并不等同于RTX 5070能在所有方面和每个配置上都战胜RTX 4090。”
实际上，根据英伟达官网提供的数据，RTX 5070主要定位于2K（2560x1440）分辨率游戏，并与RTX 4070进行对标。在启用DLSS 4后，RTX 5070在某些游戏中的帧数甚至可达RTX 4070的两倍。
