[轉貼]ATi日前公佈的Crossfire性能為驅動模擬?非實際成績?
http://bbs.gzeasy.com/index.php?showtopic=437965
這下有趣了,之前在六月份Computex大會看到ATi的Crossfire成績 竟然是ATi以一個特制的驅動(僅可以生成奇數frame的)用以模擬AFR模式下的成績 這種行為等於是ATi給評測媒體、顯卡廠商一個特制的驅動來營造CrossFire的預想成績 實際的計畫是,CrossFire恐怕要等R520上市後才一併發表 從消費者的角度來看,x800/x850的CrossFire充其量又是一個紙上發表的產品罷了. Kudos,ATi. ATI distributed a special driver to their partners prior to the Computex launch that was designed to simulate CrossFire performance, by only rendering odd frames (effectively doubling the frame rate and simulating AFR performance). Although we can't confirm that we also ran with this driver back at Computex, chances are we probably did. But more importantly, the reviews you've seen where a pair of slave cards are used aren't actually testing CrossFire, they are simply simulating the performance of CrossFire by rendering half the frames. |

ati的小動作可以說明,r520真的難產中......
nv在fx已經難產過一次了...這次換ati  |

ATI has been particularly quiet regarding CrossFire since their launch at Computex back in June. I assumed that we wouldn't see CrossFire boards and cards until August or September at the earliest, and it's really starting to look like that's going to be the case. But I'm not here to talk about CrossFire availability, I'm here to talk about performance.
There have been a number of CrossFire previews published all over the net, including our benchmarks from Computex. But what truly caught my attention was the tests over at HKEPC that showed two X700 cards working in CrossFire mode with nothing more than a simple BIOS update, no master card needed. Something about that just didn't make much sense; ATI went through all the trouble to stick a compositing chip on these CrossFire master cards, and all you really need is the BIOS from a master card? So we did some digging and Wesley actually discovered the truth behind current CrossFire performance. 這篇英文報導是在原作者看過HKEPC的 X700 CF測試才進行的研究.... 這實在是非常有趣的消息,尚待後續確認. |

目前得到的消息是 , ATI 還沒有搞定驅動程式 , 所以不願意放出太多樣品 , 聽說香港那網站有被關切過
 不管怎樣 , 想看正官裝的 CROSSFIRE 測試要再等等囉 . |

8/26日還好久,R520現在都有樣品在AIB手上,未來8/26之前,一定會有R520的消息走漏 |

老話一句, 東西沒拿到我手上自己玩過, 所有的評測, 數據, 看看就好.....
嗯~~等R520+CROSSFIRE出了跟ATI「借測」一下......XD 到時候來個G70+SLI & R520+CROSSFIRE大決戰.....

陰謀論看了不少，不過這個還真的是蠻慘的....
本來用FPGA外掛一個東西，我是不太想看成一個完整的產品，R5x0才開始整合也是ATI自己說的.... 不過，看起來像是怕R5x0拖太久所以先講一下，看起來像是"以前就有的技術"，只是重新整合實用....有點像是在宣示：ATI在和對手同世代的產品就能做到xxx。 不過，NVIDIA發表SLI產品是2004年7月、實際上市則是同年11月。 R5x0實際的推出與面市時間來看，產品晚了一年"以上"的說法，顯然已經離事實不遠了。 |

我有一個疑問...
就是在AFR模式下雖然效能是強, 可是不是不能使用在遊戲的材質貼圖上嗎?? 那3dmark怎麼執行的......XD 希望有人可以解答我的疑問?? 此文章於 2005-07-18 02:17 AM 被 b86093 編輯. |
