现在完全看不出来ps3性能哪里比360高了
你没看出来(你如果能看出来那才真的是见鬼了),但卡马克看出来了,你说我信谁?卡马克没你懂?

为什么毋庸置疑?理论值高所以性能高?别忘了SS理论值也比PS高.

.......
SS理论值比PS高?请详细说明

Keely: First I want to ask you about the console war. You know, you're a guy who everyone always looks to for the inside scoop on you know, PlayStation 3 vs Xbox 360. Now we're seeing some PS3 games here and a lot of people are saying they're not seeing a big difference between them and the Xbox 360. Do you think the PS3 will be more powerful than 360? Or, is that [the games] just what it is?

Carmack: Well, this situation is not something that has a nice simple answer like that because the truth is that the PS3 has more peak performance and that's what Sony was looking for with the decisions they made; cell architecture, and to a lesser degree the video chip decision. It gives it [PS3] more theoretical power. But what's going to matter is what you wind up delivering on the games. And I do think Sony made a less than optimal decision than Microsoft from the perspective of the game developers.
Microsoft chose to have symmetrical CPU's, have less of them, but you can program them all the same way.

Keely: Sony has this weird Cell architecture which there has been a lot of press about, but I hear its hard to program for..

Carmack: It's asymmetric. Where you have 1 processor with dual threads that are symetric on there -- where you do most of your work. But anything you want to spin off to the cells you have to break up into these small nuggets of work. For that you have to use a different compiler, different tool chain for..

Keely: So, bottom line, do you think it was a mistake?

Carmack: I do. I think the reasoning that saves them is that they have the dominant market position over Microsoft, and they can look at this and say -- developers are essentially forced to sweat blood to take advantage of Cell because its the dominant platform and they will win to some degree with that. There will be some developers that pour their heart and soul into this -- and make game development twice as diffi*** as it should be. Sony is hoping that having a higher peak performance and having some developers that will sweat bullets over this -- they may get better games out of it.

We're looking at it [PS3]. We're not a first party or second party on it. So we're looking at this across Xbox 360, PS3 and PC. The great part is, none of these consoles stink -- none of these platforms are bad. As in previous generations you would look at this and say -- this really is painful.

Keely: What about the Wii, the graphics there....but that's not what it's about?

Carmack: Yeah, they're a little bit behind, we're not on board with the Nintendo side of things.

以上是记者的访谈实录,自己看看再喷吧。而且carmack貌似没有说SONY会赢,不知道LZ的翻译是从哪句看出来的

sun的cto说过,cell上开发就是噩梦。要知道sun开发服务器软件可是老大,连msn的服务器都是sun的系统。峰值这东西就是看着yy一下,cell这东西本来就是设计的干单一任务,尤其是做simd浮点运算特别强,其他通用运算都不大行,和dsp有些像。说白了就是连乘运算厉害,可游戏里面整数运算比重很大,就算是浮点,加法运算也很多( 所谓浮点是小数点以后的部分)

这就叫峰值性能高丫。。。。。。。。。。。。。。。。。
所谓峰值就是指一个主机在最好的情况下能发挥岀的性能,最高能做到什么程度,也就是主机性能的上限。PS3峰值性能超过360,就是说PS3做到最好的情况下所发挥岀的性能会超过360做到最好的情况下所发挥出的性能,也就是说PS3性能的上限超过360。身高1米8的人可以蹲下到1米5,也可以站直到1米8,因为上限有1米8;而身高1米5的人无论站得多直也只有1米5,因为上限只有1米5。

峰值或上限是怎么来的?难道是凭空出现的吗?难道不是建立在实际的硬件基础上的吗?难道性能较差的主机的上限反而会超过性能较好的主机的上限?举例来说,XBOX的峰值性能无论如何也不可能超过360,因为XBOX本身硬件基础就不如360。所以峰值说到底还是建立在实际性能的基础上。

。。。。。知道PS2的峰值7500万个多边形怎么来的么?  渲染一条直线!!!!!!

的确PS2峰值很高,但是用作游戏呢?

知道Cell的峰值很高怎么来的么?    做连乘算法!!!!!!!

连乘在游戏里有什么用?
