Sparkle GeForce GTX 260 comes with green mode

Sparkle introduced the Calibre X260/X260 HM graphics cards, these GeForce GTX 260 models have three different modes: green, standard and overclocked. The green mode drops the core clockspeed from 576MHz to 400MHz, shaders from 1242MHz to 800MHz and GDDR3 frequency from 1998MHz to 600MHz. According to Bright Side of News, this underclock results in power savings of 30 percent. The card also has an overclocking mode, this setting boosts the core speed to 648MHz and the shaders to 1404MHz.
The fan itself is raised above the board by 5-10mm [when compared to the reference solution], resulting in more directed airflow over the aluminum + copper heat pipes heatsink. Where things turn interesting is the back of the card: Sparkle uses a single slot bracket, with only two DVI connectors on it, while the plastic cooler casing has uninterrupted exhaust - unlike all other dual-slot cards we've seen. This is a very interesting approach, which results in reducing the heating of the metal bracket. Sparkle definitely gets brownie points for this. Secondly, the board itself is modified not to make the product cheaper, but to feature greater flexibility when it comes to underclocking [going green] and overclocking [clocking' to heaven's high]. Both Calibre cards have more phases for the GPU [vGPU] and Memory [vMEM].
