惠普 Pavilion Power 15t-cb2000 (i7-7700HQ, Radeon RX 550) 笔记本电脑简短测评
Intel Core i7-7700HQ | AMD Radeon RX 550 (Laptop) | 15.60" | 2.3 kg
AMD Radeon RX 550是基于Polaris 12芯片的移动中端显卡,为笔记本二设计。它在代工厂或三星,采用改进后的14 nm FinFET工艺制造。Polaris 12芯片(代号Lexa)是比Polaris 11和21更小的芯片,采用改进的14nm工艺,比第一代(Radeon RX 400系列)具有更高的时钟频率。它具有640个着色器(10个CU),并且(至少在Pavilion 15t中)所有核心在移动版本中都激活了(其中512个在桌面版本RX 550中激活)。
根据指定的峰值性能,该芯片应该与MacBook Pro 2016中的Radeon Pro 455类似。在我们的测试中,它到达了Radeon Pro 455,最好的情况是英伟达 GeForce MX150的程度,但是仍然落后于GeForce GTX 1050。
Radeon RX 550的功能与速度更快的RX 460和所有其他Polaris芯片相同。在这里查看Polaris构架的更多细节。
根据AMD的博客文章,速度更快的Radeon Pro 460的功耗是35瓦。在“巫师3”的测试中,笔记本Pavilion 15t中的显卡为80瓦。它的位置处于更为高效能的MX150和GTX 1050之间。
