显卡显存到底多大才够用?2GB/4GB/8GB对比
http://news.mydrivers.com/1/465/465257.htm早些年,我们在测试显卡的时候就发现,通常情况下在其它规格不变的情况下,一款显卡512MB和1GB显存的游戏帧率表现差别不大。如今,游戏要求越来越高了,分辨率也提升了,对显存的要求变了吗?到底多大显存够用?2GB、4GB甚至是8GB显存有区别吗?今日,外媒Techspot进行了实际测试,选择了R9 390(8GB)、R9 290(4GB)、R9 380(4GB及2GB)、GeForce GTX 960(4GB及2GB)六款显示,以及最具代表性的几款游戏,在同场环境下进行对比(1080p、1600p两种分辨率,高低画质)。测试环境如下:CPU:Intel Core i7-6700K (4.00GHz)内存:2x 8GB Kingston Predator DDR4-3000显卡:Asrock Z170 Extreme7+ (Intel Z170)电源:Silverstone Strider Series (700w)硬盘:Crucial MX200 1TB (SATA 6Gb/s)参测显卡:HIS R9 390X IceQ X² 8GBHIS R9 290X iPower IceQ X² 4GBHIS R9 380 IceQ X² 2GBHIS R9 380 IceQ X² 4GBGainward GeForce GTX 960 Phantom 4GBGainward GeForce GTX 960 Phantom 2GBMicrosoft Windows 10 Pro 64-bitNvidia GeForce 361.43 WHQLAMD Crimson Edition 15.12具体测试结果如下:http://img1.mydrivers.com/img/20160108/s_20026371ddba40639b9c895fa9fc98d6.pnghttp://img1.mydrivers.com/img/20160108/s_5f35a156821a485780e8f6072546a4e1.pnghttp://img1.mydrivers.com/img/20160108/s_5b2e52c6310743cc9e18ebbfddd96224.pnghttp://img1.mydrivers.com/img/20160108/s_8686707554294c44b08927267a059ddf.png

《战地4》
从测试结果不难看出,无论是在1080p还是1600p分辨率,在绝大多数情况下2GB显存已经完全可以满足需求,表现和4GB显存几乎没有区别,而8GB显存则显得有些多余,基本没有必要。只有在极端情况下,比如《GTA5》1600p分辨率,FXAA、4xMSAA超高画质,2GB显存才会捉襟见肘,游戏帧率会明显低于4GB显存。所以,在选择显卡的时候,真的没有必要追追求大显存容量,更需要关注的是内核、显存带宽以及显存类型。
怎么看2g都不够吧,枭雄明显下跌严重 {:5_143:}入了390-8g的已哭晕在厕所……_(:з」∠)_ Redeon 发表于 2016-1-12 19:22
入了390-8g的已哭晕在厕所……_(:з」∠)_
你可以高特效运行黑色行动3找找平衡 少女卷轴表示,有多少显存我就可以吃多少 GTA5在爆显存情况下会自动降低特效适应显存 所以并不能代表什么 ...我的迪兰390 8G 跑 1440的 GATA V 都能跑 60FPS偶尔有掉帧的情况。。。 就是说显芯一样的情况下,4G够了? 960的2G和4G有什么区别么。。。 1600P下,960 2G和4G帧数一样?{:5_167:}怎么和国内的测评不一样
