- - ATI 9550 跟9600XT是什麼關係－＿－？搞不懂！解惑一下＾＾ (https://www.pcdvd.com.tw/showthread.php?t=432637)

9550/9600(se,np,pro,xt)都為同系列的core
早期的9600p,np都是rv350 core
後來出的9600xt就是rv360,基本上rv350跟rv360沒有什麼大改變,只是如同上面大大說的
rv360為tsmc low-k制程,且rv360多了"溫控"功能
還有用的ram,預設時脈有差
"官方"的9600p,np,9550都是用tsop的ram
而9600xt為bga的ram
有些廠商將9550用rv360 core(9600xt)然後裝bga 2.8ns ram
這樣9550就可以超到9600xt的效能(如精星的9550白金版,至尊版...)

補充一下……

9600Pro官方版本應該是BGA GDDR喔 :ase
只是AIB比較喜歡用TSOP…事實上TSOP跑300不是太困難
不過有些只是core用9600Pro，而記憶體卻跑不到300，也是掛Pro的招牌賣
這是比較值得一般玩家注意的…

Gecube有一款9600Pro,時脈分別為400/400...這就不符9600Pro的規格.

:flash: 老毛~你再不唸書會死的很慘喔!

請問一下大大，在同樣的核心時脈/記憶體時脈下，9550與9600(se、pro、xt)的效能也是完全一樣嗎? 或者驅動程式辨認出來的id不同，效能也會跟著不同?

這個問題在當初9700P/NP及9800P/NP/XT時就有類似疑問了，
答案應該是沒有

其實這個title的答案樓主可以從一些硬體資訊網站自行獲得解答

The hefty increase in clock speed is due to improvements in process technology as well as the introduction of a low-k dielectric. As we briefly explained in our 9800 XT review, the benefits of a low-k dielectric are mainly related to shielding from crosstalk in high transistor density chips, which gives us the clock speed boost we see with the 9600 XT. Because we’re just talking about an increase in core clock speed, the games to receive the biggest performance boost from the XT would be those that are GPU-limited, which unfortunately are few and far in between these days. Games that are largely shader bound such as Half Life 2 will definitely enjoy the 9600 XT’s increase in clock speed, but for now we’ll see most of the performance benefits go to waste.
