真无敌了：技嘉彪悍GTX780Ti海图赏、实测
GeForce GTX 780 Ti已经是世界上最强悍的单芯显卡，但既然开放了非公版设计，各家厂商就不客气了，纷纷用尽手段挖掘潜力。技嘉就正在准备一款新的“GeForce GTX 780 Ti GHz Edition”，频率之高令人瞠目。http://news.mydrivers.com/img/20131205/s_0ee7fbc5738c47e68806f793a299fbf7.jpg其实，技嘉此前已经推出了超频版的780 Ti，核心频率提升至1020-1085MHz，而这个新版本的基础频率就定在了1085MHz，加速频率更是达到1150MHz。http://news.mydrivers.com/img/20131205/s_c5e59e83b297409a80b3f9b085066a20.png当然了，了解NVIDIA GPU Boost技术的同学都应该知道，所谓加速频率其实并不是极限，实际运行中往往可以跑得更高，比如技嘉这款实测最高竟然能达1228MHz！相比之下，公版标称只有928MHz，实际最高993MHz，EVGA SuperClocked ACX版本标称1072MHz，实际最高1137MHz(正在打造的k|ngp|n Edition还不清楚频率)，技嘉此前的超频版最高也是这个水平。换言之，它可以比公版最高提速达24％！不过显存毫无惊喜，容量仍是3GB，频率仍是7GHz，如果能翻番到6GB就更爽了。http://news.mydrivers.com/img/20131205/9712d0268d9f4c67a8b25b2c1b9ebf48.png该卡延续了此前的非公版PCB，8+2相供电电路，双八针辅助供电。散热器是WindForce 3X，三风扇六热管，外加辅助背板，号称散热能力达450W，并能维持相对较低的温度(后边会有实测)。重量达到了1044克，但保持了双插槽身材和11.5英寸标准长度，确切地说是292×129×43毫米。发布时间和价格暂未公布，英国媒体Hexus估计可能会达到625英镑左右，约合人民币6240元。接下来先欣赏欣赏智利媒体ocaholic.ch奉上的42张实物高清照片，再看看Hexus对其进行的性能、功耗、温度、噪音、超频测试。http://news.mydrivers.com/img/20131205/7aceb755d4a34c3498f2f7a079d61466.jpghttp://news.mydrivers.com/img/20131205/efab0a9b0a8746aa882b630cb6c3d7aa.jpghttp://news.mydrivers.com/img/20131205/381bc6c44d8b48d0a7038d83b1e53483.jpghttp://news.mydrivers.com/img/20131205/c49127d7c96a45deb4bb1594f6707c35.jpghttp://news.mydrivers.com/img/20131205/s_a4759669afc9486a98691857140291c8.jpghttp://news.mydrivers.com/img/20131205/s_2f5f4d2bf90f4efaa8a9758694af7643.jpghttp://news.mydrivers.com/img/20131205/s_6fe80087cd8b47aaa28dd787bf35bd59.jpghttp://news.mydrivers.com/img/20131205/s_d2ba7cf928094080a9ca1e1f3605f8ef.jpghttp://news.mydrivers.com/img/20131205/s_96cacc4fb76040e193919106c8d4e03a.jpghttp://news.mydrivers.com/img/20131205/s_eeab406337d34fcfab8ae1d1c90299c9.jpghttp://news.mydrivers.com/img/20131205/s_c537746a0cd74c86b22393dee5b8014e.jpghttp://news.mydrivers.com/img/20131205/s_b3f93b6ad93f4b119a6a91fd938c31e1.jpghttp://news.mydrivers.com/img/20131205/s_66010f5d7ddb4fdfa125d34ee3baad16.jpghttp://news.mydrivers.com/img/20131205/s_266f0484aa04413eabec8da72c3d2e36.jpghttp://news.mydrivers.com/img/20131205/s_bc06f54f3411439891772a25306ff3f2.jpghttp://news.mydrivers.com/img/20131205/s_a65e600226e74651bd5cfacfa5e8f187.jpghttp://news.mydrivers.com/img/20131205/s_e7089b4ac09a469b93e266e90ff501cc.jpghttp://news.mydrivers.com/img/20131205/s_5dce1a39bc6a4489a71adb6b3857890d.jpghttp://news.mydrivers.com/img/20131205/s_042ed79a1c5f4b398721a00691554774.jpghttp://news.mydrivers.com/img/20131205/s_633ad4f419ac4209ace16f8be18adb8c.jpg
