Overclocking the "R600"

2.0 GHz memory frequencies? No problem.
Anh beat me to
benchmarks by a few mere hours -- when you snooze, you lose at
. Needless to say, I feel somewhat compelled to add my benchmarks to the mix as well.
The system I'm using is an Intel Core 2 Extreme QX6800, ASUS P5N32SLI-E
with 2x2GB DDR2-800. My tests this morning used the Catalyst 8.361 RC4 driver. The card used was a Radeon HD 2900 XT 512MB.
Like Anh, I was able to get pretty close to
a 2.0GHz memory clock while still keeping the system stable
. For reference, my GeForce 8800 GTX (core clock at 650 MHz, memory at 2.0 GHz) scores 14128 (1280x1024) and 11867 (1600x1200) on the same system with ForceWare 158.19.
I'm currently benchmarking the Radeon HD 2900 XTX, though I'll revist the XT if anyone has any particular requests.

An incandesent light bulb is only about 5% efficent (the light), the other 95% of the energy is wasted on heat.
Thats why the push for the world to change to the new coiled floresent bulbs.
They are over twice as efficent putting about 12% of the power to light using less power (a 20W floresent puts out as much light as a 75W bulb) and last 5 times longer.
A semiconductor is an "active" device, the "work" they perform is the millions of logic gates inside a chip being switched on and off millions of times a second and held in a given state (on or off) the entire time.
Resistors are a "static" device that simply restricts the flow of DC current by disapating it as heat (in series), or redirects the current flow (and voltage) when in parallel.
Nothing involving electricity is 100% efficient, not even wire.
Buy using better materials and using lower voltages semiconductors are becoming more efficient, but they always produce some waste in the form of heat.
