三连关注走一波~ 现在的显卡市场非常的疯狂，性能稍微强点的卡价格都涨的飞起。1650这种不被看好的显卡，一个月前价格还1000不到，现在都1300了。

而那些入门级的显卡gt1030.rx550.rx560却没怎么涨价。相信有部分人选择了这些入门卡作为过渡。

而AMD的入门卡rx550有一个隐藏福利，那就是A卡的传统艺能——开核。这里就来体验这个福利。 rx550是北极星架构的小弟，其有两个版本，一个是核心代号Lexa 512个流处理器高频的版本，一个是核心代号polaris21 640个流处理器低频版本，而后面这个版本是能开核的。我手上有一张蓝宝石rx550正好是这个核心的。

开核需要atiflash这个软件，下载后放在C盘。
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3Dac4b890315087bf47dec57e1c2d2575e%2F32d7a7efce1b9d164c242c29e4deb48f8d5464ac.jpg
然后去TPU上查找蓝宝石RX560 2G里设备ID、显存颗粒类型、显存大小一样的BIOS（设备ID可不一样，我这个RX550就是用不一样的刷的），点击下载。
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3D1efe516319f41bd5da53e8fc61db81a0%2Fd4439822720e0cf3b42af8b31d46f21fbf09aaae.jpg
然后把BIOS复制到atiflash的目录，把老长的名字改成容易打的，
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3D6b3c223cba345982c58ae59a3cf5310b%2Fe97fddc451da81cbc53a35854566d016082431af.jpg
然后用命令提示符依次输入下面的代码
cd /atiflash
amdvbflash -i
amdvbflash -p -f 0 1.rom
完成后重启，就可以发现显卡已经成功开核，流处理器从原来的640变成了768，核心频率也从原来的1071变成了1226

测试平台如下：
CPU是锐龙4750G固定4.3G

内存是英睿达C9BLM套条，在铭瑄这张主板上我超到了4000C14，铭瑄这主板超频能力还不错。

整体来看在3D MARK中开核提升了25%的性能
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3Dab54ada5b4cc7cd9fa2d34d109002104%2F901635fae6cd7b8999aa8ccb182442a7d8330e40.jpg 在CSGO中默认画质设置开核前平均帧是102开核后是120，提升约18%

古墓丽影暗影中全低特效下开核前平均帧是30开核后是36，提升约20%
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3D85b1fb88e036afc30e0c3f6d8318eb85%2F824d10385343fbf234ef106ba77eca8064388f4c.jpg
而在吃鸡全低特效下开核的帧数从57提到了72性能提升达到了理论的25%.
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3D2ad437649001a18bf0eb1247ae2f0761%2F7d10213fb80e7becf5e7b2a9382eb9389b506b4e.jpg 从上面的数据可以看出RX550开核后理论性能提升25%，实际游戏性能提升个20%。这个提升非常的巨大。当然我们还可以通过超频再提升一些性能。
超频后这张卡在鲁大师得分8.1W，提高了1W分。
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3Dc8edf2715c36acaf59e096f44cd98d03%2F4d35ab18972bd40736f862b56c899e510fb3094f.jpg
3D MARK TIME SPY中原来得分1604，超频后得分1819，提升约13%。
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3Dfef6734eb8c379317d688621dbc4b784%2F54295343fbf2b21115153406dd8065380cd78e54.jpg
开核超频后让原本只能和750Ti五五开的RX550，现在不仅能秒杀750TI甚至能摸到1050的屁股。
https://pchomes.cn/source/plugin/csdn123com_zhuanzai/display_picture.php?url=http%3A%2F%2Ftiebapic.baidu.com%2Fforum%2Fw%253D580%2Fsign%3Db02938494b6034a829e2b889fb1349d9%2F0e81f603738da977101e3763a751f8198618e352.jpg
而全新的RX550价格只要400块，二手的750Ti不仅没保修还要担心矿卡问题，价格也不给力要350，为啥不去买RX550呢。400块能有这样的性能作为一张入门过渡卡是很不错的。如果你对显存容量有需求可以选择4G版本RX550一般就加了50块钱，很划算。
