請問這兩張目前最紅的卡
它們的耗電率為多少??
建議使用電源是幾瓦
另外
它們是否也加入了自動判別的功能
比如玩 game時自然會使用大量電源
然而像那些上網文書時 這類低耗能的 工作時 ??
卡會自行把電壓等功率下降以滅低電源的負擔嗎??
以前有相關功能似乎只有 石頭牌的matrix 系列才有此功用吧??

如果你是指5850和gtx460,
那可以說5850目前一點也不紅,因為價位不降反升的關係,
amd不願將5850降價也許是聰明的,也許關係某種交接儀式,
也許有更隱晦不宣放遠未來的內部理由,更有人認為時機未到而已,
至於耗電量,TPU應該已經列的很清楚,分idle,average,peak,maximum
http://www.techpowerup.com/reviews/...60_HAWK/26.html
2D可以參考IDLE,3D以AVERAGE為基準,
但並非每人都認同這樣的測試方式,
以TPU來看,2D兩者差不多,
3D就可以發現5850卓越之處,
至於節能方式兩者不同,ati屬即動型,nv為緩動型,
可以參考這裡

你可以注意TPU的測試環境
· Idle: Windows Vista Aero sitting at the desktop (1280x1024 32-bit) all windows closed, drivers installed. Card left to warm up in idle until power draw is stable.
· Average: 3DMark03 Nature at 1280x1024, 6xAA, 16xAF. This results in the highest power consumption. Average of all readings (12 per second) while the test was rendering (no title screen).
· Peak: 3DMark03 Nature at 1280x1024, 6xAA, 16xAF. Highest single reading during the test.
· Maximum: Furmark Stability Test at 1280x1024, 0xAA. This results in a very high non-game power consumption that can typically be reached only with stress testing applications. Card left running stress test until power draw converged to a stable value.
· Blu-Ray Playback: Power DVD 9 Ultra is used at a resolution of 1920x1200 to play back the Batman: The Dark Knight disc with GPU acceleration turned on. Playback starts around timecode 1:19 which has the highest data rates on the BD with up to 40 Mb/s. Playback left running until power draw converged to a stable value.
