AMD Radeon RX 640

AMD Radeon RX 640是基于Polaris架构的笔记本电脑移动中档图形卡。它具有640个着色器(10 CU)或512个着色器(8 CU),具有不同的时钟速度。与较旧的RX 550(X)相比,RX 640似乎仅提供一半的内存带宽(64位内存总线而不是128位)。
性能应略低于旧的RX 550,因此应该比Nvidia GeForce MX150低。因此,只有低要求的游戏才能玩。在我们的Thinkpad E15基准测试中,RX640的性能比普通GeForce MX330(+ 4%)/ MX250 / MX150差。因此,对于要求非常高的游戏,性能可能不足。例如,“ Ghost Recon Breakpoint”在最低设置下平均只能达到26 fps。
