IIRC, that's the same GPU that's in the PSP2/NGP... and it'll have 4 of them.

Not a profesional but:
"The RSX (PS3's GPU) to the Xenos (X360's GPU). The RSX has 24 pixel shader pipelines and 8 vertex shader pipelines. Its capable of 136 shader operations per clock and performs 74.8 billion shader operations per second. It's clocked at 550 MHZ. The Xenos is clocked at 500 MHZ but has 48 unified shader units or pipelines. It performs 192 shader operations per clock and 96 billion shader operations per second. Think of the shader pipelines as water faucets, the bigger the faucet the more water that can go through...Same idea applies here. And this is just comparing the bare naked GPUs. I'm not even factoring in the eDRAM and Random Access Memory for the GPU and CPU and even the CPU"
Versus
"iPad 2 - 29 million Textured triangles per second and 20 million Fragment lit triangles per second"
PS: Don´t really know if this help in anything at all.

It doesn't really, since you're comparing Shader cores to triangle output. For What it's worth, 20 million fragment lit triangles a second is maybe a little above Gamecube level performance. Adding advance shaders like normal maps would drop that number even lower.arnoldocastillo2003 said:
The X360 and PS3 are capable of over 80 million triangles a second with all the bell and whistles enabled.
Like I said, it's not even close.
aficionados?
First of all, you throwin' too many big words at me, and because I don't understand them, I'm gonna take 'em as disrespect. Watch your mouth!
on topic the GPU in the NGP if clocked at 400Mhz can push 266 Million polygons per second just under the PS3 275 Million polygons per second
& fill rates of 8Gpixels per second vs PS3's GPU 4.4Gpixels per second?

But it's good to see how technology advances, impressive performance for a passive cooled chip with very low power consumption.

IMO current gen console GPUs ought to still give it a sound thrashing.
having said that it does not have to display visuals on a 50 inch HDTV. SO you can usually dumb down in some areas where the console GPU can't. Which numbers in aprticular are you lookign to compare?
OK decided to look at the anand article and compared 2 random results.
Measured on the iPad: 30 million triangles/s and 890 million texels/s
Theoretical on RSX: 275 million triangles/s and 13 billion texels/s
These number are pretty meaningless IMO, no one is daft enough to approach a tablet the same way you approach a home console.

Yeah but PS3 is not just RSX. Afaik the CELL also does some pretty impressive stuff and makes up for the weaker GPU chip.Wazzim said:

Putting it up against the PS3, might be true. But tablets will always lag behind because of heat and power issues.
