從去年Q3季之後沉寂了一陣子的顯卡市場，沒想到在這個月裡，AMD推出了Radeon HD7790，補齊了所有Redeon 7700系列的卡，究竟Radeon HD7790能有多少表現，就讓我們繼續看下去。

 

AMD Radeon HD 7790外觀開箱

 

測試產品為微星的R7790-1GD5/OC，此次為超頻版的1050 Mhz (公版為1000 Mhz)。

 

卸下外盒後還有完整的防震措施。

 

 

內容物為DVI轉D-Sub訊號轉接頭、驅動光碟、電源轉接線材和紙本說明書。

 

 

微星R7790-1GD5/OC上搭載的散熱器上加入了八公分規格的風扇來強化散熱效果。

 

 

輸出介面，左起為HDCP、HDMI、DVI-D、DVI-I。

 

 

背面照，長度為185mm，為公版設計的長度。

 

 

裸卡照，PWM供電部分為5+1設計，主要為Hi-C CAP高導電聚合物電容和SFC超導磁電感。

 

 

Radeon HD7700晶片本體，週期為2013年06周。

 

 

記憶體為hynix顆粒。

 

 

需要一組6Pin電源供電才能正常運作。

 

 

散熱器具兩根銅導管加速導熱速度。

測試總結

從上述各項結果中，可看出AMD這次推出的Radeon HD 7790在Radeon 7000系列中規格大幅提昇，相較於Radeon HD 7770具30%~40%的效能提升，而與Radeon 7850 1GD5的分數相距接近，相距約10%~20%，除非買到Radeon HD 7850 2GD5的版本，才會有較高的差距存在，若預算不夠多不妨可以考慮Radeon HD 7790，將剩下的預算做其他的升級也是不錯的。
