the PowerVR SGX 535 in the iPhone 3GS and iPod Touch 3G can push up to 28 million trianlgles per second. This is almost as much as a PlayStation 2. Unlike the iPhone 3G, which had 24 mb of dedicated video ram, the new SGX can allocate any amount of the system's 256 mb for video performance. The 535 can reach core speeds of up to 400 MHz, but this is probably underclocked in the iDevices. The PSP is capable of around 30 mil./ triangles per second, though most games for the platform run at 4-5 million trianlgles per second. In fact this spec of the PSP may be a false marketing technique by SONY, since a test showed that the device ran at 5-10 fps at 20 mil. per second. A demo applet in a video showed that a 3GS runs at a stable 40 fps while pushing up to 15 million triangles. The graphical improvement possible opens new doors to the graphics capabilities of portable gaming. The capabilities of this dwarf the crappy Intel 945GM integrated graphics in my 800 dollar laptop from 2 years ago. The chip also includes vertex shaders, texture features, and pixel shader 4.1 as well as OpenGL 2.0 AND DirectX 10.1 On the other hand, the Tegra consists of an all-in-one chipset: The CPU, GPU, and memory in one chip. All though this is efficient for power usage, this may not deliver the maximum perofrmance. It also has openGL 2.0 support and 1080p support, but only supports the old ARM11 CPU found in old devices. please tell me any other info.
