| Let's look at the maximum theoretical numbers for the Xbox 360 and PS3 GPUs.
Triangle Setup
Xbox 360 - 500 Million Triangles/sec
PS3 - 250 Million Triangles/sec
Vertex Shader Processing
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
Filtered Texture Fetch
Xbox 360 - 8.0 Billion Texels/sec
PS3 - 12.0 Billion Texels/sec
Vertex Texture Fetch
Xbox 360 - 8.0 Billion Texels/sec
PS3 - 4.0 Billion Texels/sec
Pixel Shader Processing with 16 Filtered Texels Per Cycle (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 - 16.0 Billion Pixels/sec
Pixel Shader Processing without Textures (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
Multisampled Fill Rate
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)
Pixel Fill Rate with 4x Multisampled Anti-Aliasing
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)
Pixel Fill Rate without Anti-Aliasing
Xbox 360 - 4.0 Billion Pixels/sec (8 ROPS x 500MHz)
PS3 - 4.0 Billion Pixels/sec (8 ROPS x 500MHz)
Frame Buffer Bandwidth
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)
Texture/Vertex Memory Bandwidth
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)
Shader Model
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.
Some PS3 GPU (RSX) specs are still not confirmed as final. It's assumed to have 24 pixel pipelines, 8 vertex pipelines, 8 ROPS (raster), and 550MHz clock speed. But any of those could change, especially the clock speed.
Are there any other GPU spec categories worth adding?
UPDATE: RSX figures were updated to represent GeForce 7 based architecture with 24 pixel pipelines, 8 vertex pipelines, 8 ROPS, 500MHz core, and 650MHz memory. In other words, it dropped from 550MHz/700MHz to 500MHz/650MHz. |

| | Oh my god! How is the P$3 supposed to even compete with the PC or xbox 360 when it's not even as powerful? How is it supposed to compete with Wii with last-gen gameplay? |
|
| | | Untapp3d potentia1z, foo... how else should they compete? By engineering something worthwhile? Sheesh, kids these days. |

| | Thanks, very interesting and lets see if the PS3 specs stay the same or change when the machine is released. |
|
| | | I got this link from a guy raving about the graphical superiority of 360 over PS3. When the general understanding is RSX's raw horsepower is greater than the more efficient Xenos, what does this very comprehensive list mean? I've seen the games at E3 and frankly I would risk a guess and say nothing. |

Xbox 360 has the advantage in most cases.
Based on your list, where does it not have an advantage? Everything looks to be in favor for the X360. |
|
| | Don't forget to add VRAM.
X360: 480MB maximum
PS3: 224MB dedicated |

| | Where exactly is the truth? These figures, based on the games I've seen on both systems, mean nothing. |
|
| | These specs show why the newest X360 games at E3 looked miles ahead of anything on PS3.
Gears Of War, Fear Effect, Moto GP 06... nothing on PS3 comes close.
The best looking PS3 game, Assasin's Creed, was actually running on an Xbox 360.
The only fools who think PS3 games looked better are the same idiots who think PS2 had better graphics than Xbox and GameCube. Untapped potentials ftl. |
|
| | | Huh where did you get that figure from? I doubt xbox 360 has over 480MB dedeicated to VRAM alone. |
