Most powerful GPU

Yeah, it is real deal monster!

It's not going to have a snapdragon processor. It's using the ARM cortex chip. Both are 1ghz, but that's only clock cycles and isn't really a meaningful measure of performance. The ARM architecture is superior to that of the snapdragon. The on-chip GPU _is_ more powerful, but in the case of a small-screen Android device this isn't too terribly meaningful; the current batch of mobile chips are all more than up to any task the OS is capable of performing with no real lag.

After a certain more, more power isn't necessarily a tangible benefit unless someone is coding to use that power. In the case of current generation mobile handsets the dominant chip is the snapdragon so that is the performance level to which developers will code. The extra muscle of the ARM Cortex A8 is nice to have, but the CPU isn't anything that's going to make peoples' heads spin around 360 degrees or anything.

Honestly, I think that if the Galaxy S takes off, what's going to seal the deal is going to be the screen; that's the real differentiating factor. In most other respects, it's identical to all the other 4" handsets that are coming out from Dell, Toshiba, HTC, Motorola, etc. That said, I can't downplay how cool the screen is or how big a differentiating factor it's going to be. I'm just hoping the build quality and software integration measures up to the screen and specs.

This information is incorrect. Snapdragon is ARM architecture, heavily customized (a rebuild from the ground-up is the best way to describe it) and runs the ARMv7 instruction set. It's about 5-10% more efficient per clock cycle than a standard ARM Cortex A8 (example being the TI OMAP3430 in the Droid) though Hummingbird is able to match Snapdragon in performance due to its own custom modifications (by Intrinsity) to the Cortex A8 architecture. However, Hummingbird is significantly more power efficient than the current 65 nm Snapdragons because of its 45 nm feature size.

In addition, more powerful processors and graphics performance DO produce tangible benefits even when they're "overkill". The more powerful a processor is, the faster it can complete a task and return to an idle state where it consumes very little energy. Processing in bursts like this, even if it causes higher peak power draw, is more energy efficient than a slower processor running continuously at a lower power draw. This applies to both CPU and GPU processors, and as long as the maximum power draw remains fairly reasonable, there are both performance and efficiency gains to be had, regardless of whether the performance gains themselves are tangible. The improved efficiency of the 45 nm process just compounds this fact.

The size of the screen is also inconsequential when what we're talking about is the number of polygons being drawn and textured on the screen. The resolution of the screen is important when determining the number of pixels per frame that need to be processed, but that's a completely separate value from the number of pixels that are physically on the display. The PenTile system that Samsung employs uses a special arrangement of pixels and unique image processing algorithm to produce an image that is able to scale appropriately with video output as well as produce (supposedly) accurate color representation. This method has fallen under a little bit of fire recently for the image quality produced by the Samsung PenTile AMOLED display on the Nexus One under certain circumstances (hence the 'supposedly' before), and it'll be interesting to see how this has been addressed in the Super AMOLED display.

In the future I'd ask that you not post such things if you are not sure what you are talking about.

holly 1ghz thats alot for a litle device

Little Bighorn but not for Yankees, lol!
