考虑到外形因素,175瓦的移动版GeForce RTX 4090令人印象深刻,但与450瓦的桌面版相比,它并不逊色。早期的基准测试显示,移动版的运行速度比适当的4090桌面卡慢35%到45%。
Gaming Laptop / Notebook Geforce

在2023年CES上正式发布了用于笔记本电脑的GeForce 40系列后,Nvidia现在已经准备好为世界各地的游戏玩家发货。我们的第一批测试样品包括 Razer Blade 16微星GT77配备了175瓦 移动GeForce RTX 4080移动GeForce RTX 4090,分别是已经可以预购的每一款。这两个型号给了我们一个很好的机会,可以与 桌面RTX 4080台式RTX 4090.然而,在更仔细地看了这四种GPU所能提供的东西之后,很明显,移动版本可以被更好地命名。

人们可能期望移动版RTX 4080的性能与桌面版RTX 4080更相似,但情况完全不是这样。根据我们下面的3DMark基准测试,移动RTX4090更接近于桌面RTX4080,而175W的移动RTX4080可以慢35%左右。此外,移动RTX 4080可以在更低的TGP包络上配置,只有100W,性能差距更广。

看看每个GPU的核心规格,就会发现存在差异的原因。如下表所示,移动RTX 4090与桌面RTX 4080共享相同数量的管道、TMU、ROPs、RT核心和张量核心。与此同时,移动RTX 4080的规格被全面截断,甚至包括其内存总线宽度。

如果你在市场上购买一台新的GeForce 40游戏笔记本电脑,并具有台式机RTX 4080的性能,那么你绝对应该考虑配备移动RTX 4090而不是移动RTX 4080的笔记本电脑。基于迄今为止的性能结果,有充分的理由将移动RTX 4080和移动RTX 4090分别更名为移动RTX 4070和移动RTX 4080。更直接的命名有可能帮助笔记本电脑买家更好地衡量这些型号的显卡与台式机相比的性能。
