ZT[翻译](一篇解释目前PS3画面差现象的好文)一个游戏开发者的观点:XBOX360比拼PS3
A Game Developers View: Xbox360 vs PS3
>> From hardcoreware.net:

引用:
Being a video game developer (I develop for both, Playstation 3 and XBOX 360) people ask me almost daily which platform I think is better. These are my personal feelings, in no way does this reflect my employer.

Performance: On paper, the PS3 is more powerful. In reality, its quite inferior to the 360. Without getting into too many details, the three general-purpose CPUs the xbox360 has are currently FAR easier to take advantage of than the SPUs on the PS3. I suspect a few years down the road some high budget, first party PS3 exclusive titles will come out that really take advantage of the SPUs and do things the XBOX 360 cant, but I dont think the console is worth buying based on this speculation (for some it will be though, well have to wait and see how these games turn out).

Graphics: The XBOX 360 is a clear winner. The GPU is more powerful. It has more powerful fillrate, and far more pixel and vertex processing horsepower. Part of the reason is their choice of memory, and architecture of pixel and vertex procesing. I cant get into details but the same vertex shader will run much slower on the PS3 than the XBOX 360. The 360 also has a clever new way rendering high definition anti aliased back buffers. To accomplish the same effect on PS3 is prohibitively expensive. For this reason I think many games will have no choice but to run in non-HD resolutions on the PS3 version, use a lower quality anti aliasing technique, or do back buffer upscaling. The end result in all cases is going to be noticeably worse image quality.



作为一个家用游戏开发者, 同时为PS3和XBOX360开发游戏, 每天都有人问我到底这两个平台到底那个更好. 下面我来讲讲自己的观点:

运算能力:

理论上, PS3更强, 但实际上, PS3要比360弱一些. 简单的说, 360的三个通用型CPU比PS3上面的SPU要容易运用很多很多. 当然, 很有可能几年以后, 会出现SONY自己开发的独占平台的高开发费用的游戏出现来真正运用到这些SPU, 来做到一些360的CPU无法做到的事;但我觉得仅仅基于这一点, PS3是不值得购买的.(我们而且还要等到这些游戏真的出现以后再看.)

图像表现上:

360是毫无疑问的赢家. 它的GPU更加强大. 它有更高的填充率, 远远更强的象素的顶点运算能力. 其中部分的原因是内存的选择, 象素和顶点运算的构架. 我不想深入的解释但同样的顶点SHADER在PS3上要慢很多. 同时, 360有一种非常聪明的在高精度模式下抗锯齿的方法. 而在PS3上达到同样的效果代价非常昂贵. 因此我认为很多游戏在PS3版本上会不得不以低分辨率运行(目前已经发布的PS3游戏已经证实了这一点), 使用效果差一些的抗锯齿技术, 或者进行BACK UPSCALING. 最终的结果都会导致很明显的图像质量降低..
