PS3GPU VS XBGPU

前两天看见某人说  PS3的 GPU不如XB的 ~~~~~

一直不服~~~今天去一查   竟然是真的。。。。。失望了


Let's look at the maximum theoretical numbers for the Xbox 360 and PS3 GPUs.

[b]Triangle Setup[/b]
Xbox 360 - 500 Million Triangles/sec
PS3 - 250 Million Triangles/sec

[b]Vertex Shader Processing[/b]
Xbox 360 - 6.0 Billion Vertices/sec (using all 48 Unified Pipelines)
Xbox 360 - 2.0 Billion Vertices/sec (using only 16 of the 48 Unified Pipelines)
Xbox 360 - 1.5 Billion Vertices/sec (using only 12 of the 48 Unified Pipelines)
Xbox 360 - 1.0 Billion Vertices/sec (using only 8 of the 48 Unified Pipelines)
PS3 - 1.0 Billion Vertices/sec

[b]Filtered Texture Fetch[/b]
Xbox 360 - 8.0 Billion Texels/sec
PS3 - 12.0 Billion Texels/sec

[b]Vertex Texture Fetch[/b]
Xbox 360 - 8.0 Billion Texels/sec
PS3 - 4.0 Billion Texels/sec

[b]Pixel Shader Processing with 16 Filtered Texels Per Cycle[/b] (Pixel ALU x Clock)
Xbox 360 - 24.0 Billion Pixels/sec (using all 48 Unified Pipelines)
Xbox 360 - 20.0 Billion Pixels/sec (using 40 of the 48 Unified Pipelines)
Xbox 360 - 18.0 Billion Pixels/sec (using 36 of the 48 Unified Pipelines)
Xbox 360 - 16.0 Billion Pixels/sec (using 32 of the 48 Unified Pipelines)

[b]Pixel Shader Processing without Textures[/b] (Pixel ALU x Clock)
Xbox 360 - 24.0 Billion Pixels/sec (using all 48 Unified Pipelines)
Xbox 360 - 20.0 Billion Pixels/sec (using 40 of the 48 Unified Pipelines)
Xbox 360 - 18.0 Billion Pixels/sec (using 36 of the 48 Unified Pipelines)
Xbox 360 - 16.0 Billion Pixels/sec (using 32 of the 48 Unified Pipelines)
PS3 - 24.0 Billion Pixels/sec

[b]Multisampled Fill Rate[/b]
Xbox 360 - 16.0 Billion Samples/sec (8 ROPS x 4 Samples x 500MHz)
PS3 - 8.0 Billion Samples/sec (8 ROPS x 2 Samples x 500MHz)

[b]Pixel Fill Rate with 4x Multisampled Anti-Aliasing[/b]
Xbox 360 - 4.0 Billion Pixels/sec (8 ROPS x 4 Samples x 500MHz / 4)
PS3 - 2.0 Billion Pixels/sec (8 ROPS x 2 Samples x 500MHz / 4)

[b]Pixel Fill Rate without Anti-Aliasing[/b]
Xbox 360 - 4.0 Billion Pixels/sec (8 ROPS x 500MHz)
PS3 - 4.0 Billion Pixels/sec (8 ROPS x 500MHz)

[b]Frame Buffer Bandwidth[/b]
Xbox 360 - 256.0 GB/sec (dedicated for frame buffer rendering)
PS3 - 20.8 GB/sec (shared with other graphics data: textures and vertices)
PS3 - 10.8 GB/sec (with 10.0 GB/sec subtracted for textures and vertices)
PS3 - 8.4 GB/sec (with 12.4 GB/sec subtracted for textures and vertices)

[b]Texture/Vertex Memory Bandwidth[/b]
Xbox 360 - 22.4 GB/sec (shared with CPU)
Xbox 360 - 14.4 GB/sec (with 8.0 GB/sec subtracted for CPU)
Xbox 360 - 12.4 GB/sec (with 10.0 GB/sec subtracted for CPU)
PS3 - 20.8 GB/sec (shared with frame buffer)
PS3 - 10.8 GB/sec (with 10.0 GB/sec subtracted for frame buffer)
PS3 - 8.4 GB/sec (with 12.4 GB/sec subtracted for frame buffer)

[b]Shader Model[/b]
Xbox 360 - Shader Model 3.0+ / Unified Shader Architecture
PS3 - Shader Model 3.0 / Discrete Shader Architecture

Xbox 360 has the advantage in most cases.

SomePS3 GPU (RSX) specs are still not confirmed as final. It's assumed tohave 24 pixel pipelines, 8 vertex pipelines, 8 ROPS (raster), and550MHz clock speed. But any of those could change, especially the clockspeed.

Are there any other GPU spec categories worth adding?

[b]UPDATE[/b]:RSX figures were updated to represent GeForce 7 based architecture with24 pixel pipelines, 8 vertex pipelines, 8 ROPS, 500MHz core, and 650MHzmemory. In other words, it dropped from 550MHz/700MHz to 500MHz/650MHz.

如果说GPU差一点我还是承认的，但是别忘了三红机为了这个高指标牺牲了质量，三红甚至花屏报废的问题大多都是因为GPU造成的，因此指标高没用。

其实PS3 GPU需要CELL CPU协助来发挥最高效能.通常独占游戏才能发挥高於360的.
我觉得PS3只得CELL CPU强,其他硬件都很一般的.未发售之前sony和很多媒体都只是宣传CELL CPU和篮光光驱的,其他很少谈到.:sg

综合性能强大就OK了.......

支持楼上几位，XB的硬伤太突出了，三红，存储介质容量小~~~

路过.同意楼上几位说法.支持.

这个数据好像有点不是很有力吧，就等于前一代架构的GPU与后半代GPU相比较，XGPU是统一渲染架构的，里面的流处理单元是可以任意分配工作，灵活性大，可以一起起作用也可以拍按比例来协调工作，这样比的话确实意义不大。

到了今年八月,两款主机新版出炉,大家就可以再次一比高低了.

这难道是GTA4 PS3只有6XX多P, 而XB版本的有720P的原因么？

单纯地比拼硬件性能是不可取的,关键还是整体性能.

关键看游戏制造商的水平，看看GT5和PRG4就知道了！

X360版的分辨率（画面清晰）高，PS3版的特效（比如爆炸效果）好。

东西要看综合的!~
GPU高有什么用!~!~
牙根就发挥不出来性能!~
东西是要要合适的!~
GPU的指标只是为了宣传的!~ 要自己看游戏的效果!~!~

不知道360要是SONY设计会是怎样?????????????:@hkhk

单纯地比拼硬件性能是很难分高下的,就当年的PS和土星时代,土星当时的性能比PS高但最终还是PS获胜,关键的是靠游戏的支持!

关注下吧
当初NBA2K6在XO平台独占的时候那画面让人震撼
之后妥协了PS3 现在的画面一般 :(
XO的三红太麻烦了，而且开机关机都有时间限制，真不知道我是玩机器还是机器玩我:aeth

现在几乎只玩XB360，战争机器，使命召唤4等。PS3就只有MGS4值得期待

图形当年2D性能也比PS好很多，最后没用，还是没游戏
PS2和XBOX更不能比了，最后XBOX怎样大家都看到了

PS3可能在某些参数上不如三红机，但这不要紧
要命的是赶快出MGS4，FF13，BIO5
不如大家都玩儿完

ps.我在高清论坛看到很多人拿PS3跟专业高清播放设备比的，没人提三红机啊

支持索尼就是了

关键看综合实力.......

怎么一会儿PS3都不如360了?怎么可能呢?土星2D是比PS强,可是3D却不如PS,当年3D画面可是大势所趋啊

忠实SONY FANS,路过的,
总觉的SONY的每件产品设计很赞:shll :shll

CELL我记得是8个同样的CPU吧！
XO也是8个？？
怎么就说XO一定强了？？
