NVIDIA GeForce MX450

Nvidia GeForce MX450(N18S-G5,N18S-G5-B,N18S-LP代号)是笔记本电脑专用的入门级移动图形卡。它使用与GeForce GTX 1650相同的TU117芯片,但减少了64位的内存总线。此外,MX450是首款支持PCIe Gen 4 x4的移动GPU。

当前有四个具有不同规格和性能的不同版本:

N18S-G5-B:GBD-128封装,1395-1575 MHz,GDDR6 5001 MHz,28.5 W

N18S-G5:GB2E-64封装,1395-1575 MHz,GDDR6 5001 MHz,25 W

N18S-G5:GB2E-64封装,1395-1575 MHz,GDDR5 3501 MHz,25 W

N18S-LP:GB2E-64封装,720-930 MHz,GDDR6 5001 MHz,12 W

尤其是LP =低功耗型号比典型的25瓦型号慢得多。

25瓦GDDR6 N18S-G5应该比GeForce GTX 1050快20%,但当然要低于GTX 1650(Max-Q)。因此,要求苛刻的游戏(例如“地平线零黎明”)应运行最低设置。 F1 2020等要求不高的游戏可以中高设置和全高清运行。

TU117芯片是台积电(TSMC)12nm工艺制造的,由于功耗较低(TGP指定为12至28.5 W),因此也适用于轻薄笔记本电脑。通常,它打算用作基于Tiger Lake-U的笔记本电脑的附加图形卡。
