What's inside your iPad? Tablet tech explained  Processors and
graphics inside iOS, Android and other tablets  Returning to the
Nvidia Tegra 2, it uses what's called the ultra-low power (ULP)
GeForce GPU. Think DirectX 9 and a card with four pixel shaders
and four vertex shader cores. It's capable of 5x Coverage Sample
Anti-aliasing (CSAA) and 16x anisotropic filtering. Running at
300MHz and with each core executing two FLOPS per clock, that's
a peak output of 4.8GFLOPS. But because these aren't unified
shaders, it would take careful optimisation to get the best out
of them.  Remember PowerVR? That's the de facto standard in the
mobile world. Its tiled-based deferred rendering in a power-
limited environment has delivered better performance per watt
than Z-buffer alternatives.  Galaxy tab  The current range in
almost all SoC solutions is the PowerVR SGX5xx series. Usually
running at 200MHz, all the models use a Universal Scalable
Shader Engine (USSE). It's able to perform geometry, pixel and
GP-GPU operations.
