正式如此, 所以我才會假設 Fermi 的 SP 在遊戲下跟 GT200 的差不多 結論就是怎麼算都不會到 40%, 不過這是非常粗操的估算, TMU 跟 ROP 性能都沒算進去 平心而論, 480 SP 版本的平均能有 20 % 我覺得就很強了, 高解析才可能到30% 以上 當然, 不同遊戲可能有不同結果, 這個 20~30 % 可能會被放大到 40% 這次遊戲的重心我覺得是在特效方面, 像是反鋸齒, 與DX11 相關, 所以高解析, 特效全開的情況下會有放大的效果, 就像是 5 FPS VS 7 FPS 一樣 還有最重要的: PHYSX... 畢竟, 遊戲裡CUDA 相關用最兇的大概就是物理特效

NV 的 SP 結構, 是屬於較為多功能的, 特別是 Fermi 又加入許多語言的原生支援, 我認為在 CUDA 下可以直接吃舊的CUDA軟體沒有錯. 而且還可能可以藉由減少對 CPU 的依賴來降低瓶頸, 提高效能 至於記憶體頻寬, 384bit GDDR5 VS 512bit DDR3, 我不覺得哪裡會輸 TMU 這裡可以說是最大的一個不確定因素, SP 效能比較容易推算, 但是 TMU...? 天曉的會是沿用還是有新的設計 我也只能假設 32 個 SP 搭配4 個 TMU 是CUDA 架構下最有效率的配置

看到480sp的消息後
把原本要升級gtx480的預算拿去買ps3+遊戲了 今年除了sc2以外沒甚麼吸引我的pc game tv主機畫面雖然不好 但是有想玩的遊戲 還是很值得(mlb the show.戰神3.ff13.特攻4等) 電腦就用5870繼續撐吧 |
