The Omnia HD runs on the OMAP 3x chipset (most likely the 3430) from Texas Instruments (TI), which is based on the ARM Cortex A8 architecture, and includes a graphics co-processor which uses Imagination’s POWERVR SGX graphics technology. OMAP 3 is the next generation chipset on from the OMAP 2 family that was used in the Nokia N95, Samsung i8510 and a number of other popular devices and TI say the OMAP 3 provides three times the ARM performance of previous ARM 11 based processors. The integrated POWERVR SGX graphics technology provides graphics, imaging and video acceleration and enables the support of Open GL ES 2.0 and Shader 4.1 graphics APIs.
Undoubtedly, the OMAP 3 will provide the Omnia HD with better benchmark results, but what does this mean in the real world? The new silicon technology means the Omnia HD is able to encode and decode 720p HD video in real time, something which previously wasn't possible. It also means that the operating system and applications can run more quickly. The difference will be most obvious in processor intensive tasks, but it is worth noting there’s not a directly proportional relationship between processor performance and device performance. Clearly a better performing processor will help, but there are other constraints involved too and many different factors go into overall performance. Just as significant is that the amount of power needed to perform the same amount of processing is less, potentially opening up energy savings, though this is likely to be more than offset by the fact you'll be doing more with the device.
Kroll on the Omnia HD. Great graphics and touch based gameplay.
HD video support aside, the improved graphics support, most notably Open GL ES 2.0, may in the long term be the most obvious visible improvement. It provides the potential for near console graphics quality (they use similar APIs), and will be a very significant step up from current levels. For reference, the iPhone, rightly lauded for its graphics capabilities, uses only OpenGL 1.1. It does require developers to take advantage of the new capabilities, but it is clear from talking to Samsung that this is one of the areas that they will be looking to promote and exploit as a differentiator. The Omnia HD will ship with a couple of games, including Kroll, which looked absolutely spectacular, even if the game play was a little suspect.
Direct performance comparisons between different silicon families are difficult, but it is fair to say that the OMAP 3 chipset comes close to matching Intel's ATOM processor, which is best known for its use in the recent surge of netbook computers. The OMAP 3 chipset manages this despite using approximately half the amount of power. The important point is that in processing terms the Omnia HD will be effectively matching the performance of current netbooks - that's a significant step on the road to mobile - laptop convergence.
