可惜XO机能挖掘到顶了，PS3刚刚开始。

PS:DX10之类的言论就不要搬到这个帖子里面来了，***份~

你掘的?你这种言论才***份呢

该用户已被禁言

久多：PS3靠的是游戏乐趣~~~~靠画面？那是MS系的做法~~~

是真的!所以说XBOX30我更喜欢!也更喜欢盗版!坚决打击正版!打击暴利!

打击正版就不要了吧，正版都没有了，D版从哪儿来？其实ms和sony有一个重要区别：盖茨曾说过，不要对盗版商太苛刻，盗版也是普及市场占有率的方法之一，咱们有钱……（未经证实言论）。

内酷反川

PS3机能被神话了~~~~

其实不过如此！

360 developers will probably start to cry or to laugh isterically after having read that.

Repeat with me: every time someone tries to convince me that the product of some engineering work operates at > 95% efficiency the bull****s bell start to ring in my head!

So it does not slow down because of mem bw..it slows down because of slower shaders. I see..95% efficiency my ass.

it's not just about vertex shading. vertices have to be fetched again, pre and post transformed vertex data caches get trashed with data you don't need, triangles have to be assebled (burning further post trasformed cache bandwidth again) set up and rasterized again..and every clock cycle lost rasterizing something you already rasterized it's a clock cycle you lost that could have been spent on some useful workload. Truth is that for any opaque primitive with a reasonable long pixel shader edram is a complete and total waste since even a 64 bit data bus to external memory (gddr3) + compression would be enough to sustain your fb bw with AA 4X on.
Edram is a win for fillrate intensive + simple shaders rendering (particles..)

RSX will outperfom Xenos when it comes to AA in the vast majority of cases/titles. I have absolutely no doubt about that. Wish I could disclose some number.. anyway it will be clear pretty soon that RSX is very good (easy to use/very fast) at AA.

-Xenos USA is far from being an efficient monster.
-USA has little effect in console development.
-MS ATI 720p 2/4XAA for free is bunk.(see: COD3 and THPS8)
-The EDRAM logic is less useful when it comes to HD rendering.
-Including only 10MB of paltry EDRAM with ROPs decoupled is a mistake.
-Tiling works perfect on paper not very less so for real games development.
-Xenos excel with simple shaders and non physics calculated particles effect.(see: Lost Planet)
-Cell excel with physics calculated particles effect.(see: G80 demo)
-RSX excel with complex next gen shaders.
-RSX is a modified NV47 with specialized AA hardware.

天啊，这年头还有搬人家论坛上喷人的话来当论据的小白~~~~~

恩，看LS被人家忽悠的，哈哈
