Integrated Graphics

Initially some first generation Atom variants were 32 bit and without integrated graphics. Newer releases support 64 bit instructions. In 2009, Intel announced the second generation Atom processors N450, D510 and D410 with integrated graphics built using 45 nm chip manufacturing technology.

Intel GMA 3150, a 45 nm shrink of the GMA 3100 with no HD capabilities, was included as the on-die GPU. This reduced power consumption and cost as compared to having separate graphics processing chip on motherboard. Earlier Atom variants like Atom 330 used Intel 945 series chip-sets on motherboards.

Benchmark results show new Atom N2800 has much better graphics as compared to it's older brothers but it cannot compete with DirectX 11 compatible AMD E-350 graphics. More benchmarking results can be accessed at VR-Zone website.

The graphics subsystem in Atom N2800, up to now it was known that Intel to build its new GMA 3650 HD, it would adopt the core PowerVR SGX545, with support for DirectX 10.1 and OpenGL 3.0, the hardware decoding MPEG-2 , MPEG-4 part 2, VC1, WMV9, H.264. CPU world published that intel is facing problems with DirectX drivers for N2800 more on CPUworld.
