Dual-Core 1 GHz ARM Cortex-A9 MPCore CPU.Screen: 2048x1536 pixels, LCD at 264 ppi, LED-backlit. Full screen image effects still out of reach. However, it is likely that your game will perform best with bumpmapping only on crucial objects. IPad2: The A5 can do full screen bumpmapping, assuming the shader is simple enough. Accelerometer, Three-axis Gyro, Proximity Sensor, Ambient Light Sensor, Magnetometer.IPad: Similar to iPod Touch 4th Generation and iPhone 4. Mechanical keys: Home, sleep, function switch, volume.Wifi + Blueooth 2.1 + (3G Cellular HSDPA, 2G cellular EDGE on the 3G version).Accelerometer, Proximity Sensor, Ambient Light Sensor, Magnetometer.Screen: 1024x768 pixels, LCD at 132 ppi, LED-backlit.Front 1.2 MP with geotagging, tap to focus, and 720p HD video at 30 fps.Rear 5.0 MP backside illuminated CMOS image sensor with 1080p HD video at 30 fps, face detection and video stabilization.Apple A5 Dual-Core 1GHz (underclocked to 800MHz) ARM Cortex-A9 MPCore CPU.Screen: 1136圆40 pixels, LCD at 326 ppi.Rear 0.7 MP CMOS image sensor with 720p HD video at 30 fps and LED flash.Apple A4 1 GHz (underclocked to 800MHz) ARM Cortex-A8 CPU.This is the average hardware of the app market as of July 2012 iPod Touch 4th generation Requires scripting optimization for complex games. IPod Touch 3rd gen: Shader-capable hardware, per-pixel-lighting (bumpmaps) can only be on small portions of the screen at once. Samsung S5L8920, 833MHz (underclocked to 600MHz) ARM Cortex-A8 CPU.IPod Touch Models iPod Touch 3rd generation Rear 8.0 MP infra-red cut-off filter, back-illuminated sensor, 1080p HD videos at 60 fps.Apple A8 Dual-Core 1.4 GHz Apple-designed ARMv8-A 64-bit CPU.Apple A7 Dual-Core 1.3 GHz Apple-designed ARMv8 64-bit CPU.Front 1.2 MP tagging, tap to focus, and 720p SD video at 30 fps.Apple A6 Dual-Core 1.3 GHz Apple-designed ARMv7s CPU.But if your game isn’t trying to push limits of the device, optimizing scripting and gameplay is probably as much of a waste of time on this generation of devices as it is on PC. However, optimizing your shaders is still crucial. The iPhone 4S, with the new A5 chip, is capable of rendering complex shaders throughout the entire screen. Rear 8.0 MP infra-red cut-off filter, back-illuminated sensor, 1080p HD videos at 30 fps.Apple A5 Dual-Core 1 GHz ARM Cortex-A9 MPCore CPU.Front 0.3 MP (VGA) with geotagging, tap to focus, and 480p SD video at 30 fps.Rear 5.0 MP backside illuminated CMOS image sensor with 720p HD video at 30 fps and LED flash.Screen: 960圆40 pixels, LCD at 326 ppi, 800:1 contrast ratio.This is the average hardware of the app market as of July 2012 iPhone 4 IPhone 3GS: Shader-capable hardware, per-pixel-lighting (bumpmaps) can only be on small portions of the screen at once. 3 megapixel camera with video capture capability.Current device shader performance can compared on gfxbench which compares different hardware features using benchmarks. Samsung Galaxy F23 5G (6GB RAM.The following list summarizes iOS hardware available in devices of various generations.
