PowerVR SGX544 vs PowerVR SGX554MP4 vs PowerVR SGX535

PowerVR SGX544

The PowerVR SGX544 is a integrated graphics card for tablets and smartphones (often in ARM based SoCs). It usually clocks at 384 MHz and offers 4 dedicated pixel- and 2 vertex shader (MP1 version). The card supports DirectX 9_3 and OpenGL ES 2.0 and is used in Android based tablets and smartphones. There are also versions with more clusters. See e.g. the PowerVR SGX544MP2 with two clusters.

PowerVR SGX554MP4

The PowerVR SGX554MP4 (series 5XT) is an integrated graphics card usually used in ARM based SoCs. It is e.g. used in the Apple A6X (iPad 4) SoC. It offers 4 graphics cores with 8 SIMDs each and is able to reach 76.8 GLOPs at 300 MHz. The GPU itself supports OpenGL ES 2.0, DirectX9 and OpenCL 1.1. In the Apple A6X the GPU cores are positioned near the two 64 Bit memory controllers leading to a very good memory bandwidth at the time.

PowerVR SGX535

The PowerVR SGX535 is an integrated graphics card that can be found in mostly ARM based SoCs for tablets and smartphones. It offers 2 pixel and 2 vertex shaders that are usually clocked at 200 MHz. The GPU supports OpenGL ES 2.0, DirectX 9.0c and OpenGL 2.1 and was announced in November of 2007. It was used e.g. in the Apple iPad 1 and by Intel as GMA 500.
