多核定單核好?

[siriso]

我render一個有幾百萬粒子既sence,我用amd althon x2 dual core 4200+
render一個300 frames既animation要用成廿粒鍾,本身有4gb ram
如果用單核會唔會快d?因為聽過話單核會快過雙核...定系系時候應該換個更新既cpu呢??
thx!

我當然唔清楚你整緊咩animation, 但我覺你應該試下用technical skill去減少場境裡面既particle number，其實唔系咁多機會一定要用到幾個million既particles既.


另外20個鍾裡面，有幾多個％系花左系shading, 有幾多個％系花左系其他地方，比如load texture, raytrace 之類。

Which software are you using? Some softwares support multi-thread, some don't. So you have to check with your software and make sure it support multi-threading for particles.

Besides, some softwares make use of your video card when render particles (like Maya's hardware renderer), so having a faster CPU really doesn't help with particle rendering unless it's using software render.

一定唔會. 因為目前無任舊單核 u 可快過較能高又省電之雙核 u~! 更何況樓主還見到有廠出新單核賣嗎?
就算從前人家做3d想快的,也要幾部勁機內聯一起 render. 所以機本上樓主呢個問題已過時~!
