Submission + - Ray tracing for gaming explored (pcper.com) 3

Vigile writes: "Ray tracing is still thought of as the 'holy grail' for real-time imagery but because of the intense amount of calculations required it has been plagued with long frame render times. This might soon change, at least according to an article from Daniel Pohl, a researcher at Intel. With upcoming many-core processors like Intel's Larrabee he believes that real-time ray tracing for games is much closer than originally thought thanks in large part to the efficiency it allows with spatial partitioning and reflections when compared to current rasterization techniques. Titles like Valve's Portal are analyzed to see how they could benefit from ray tracing technology and the article on PC Perspective concludes with the difficulties combing the two rendering techniques as well as a video of the technology in action."

Comment 520mAh vs 2200mAh (Score 2, Informative) 349

The capacity difference between the two cells is not
as large as the Amp-hour rating would seem to indicate.
Li-ion cells operate at about 3.6 volts, while NiMH cells
operate at about 1.2. Thus, assuming constant voltage
during discharge and zero internal resistance (incorrect,
but it makes this easier), you can calculate capacities of:

1.2V * 2.2Ah = 9.5kJ for the AA cell and
3.6V * .53Ah = 6.7kJ for the Li-Ion cell.

Given the higher energy density per mass of Li-Ion
cells and the form factor flexibility ditching the
AA provides, this seems like a good tradeoff.
