Sparkle has launched two new cards in its Calibre series, the Calibre X250 and X250G. Both cards are based on Nvidia's GTS 250 GPU and the only difference is the amount of memory, as the X250 comes with 512MB while the X250G has 1GB of GDDR3 memory.

The new Calibre cards are both based on Nvidia's GTS 250 GPU and come with a black PCB, 256-bit memory interface, 128 stream processors, D-Sub, DVI and HDMI outputs, Dual Fly Fan cooler and Sparkle's SPA Tune OC software. The SPA Tune OC software provides three modes, Overclocking mode (OC), Standard mode (STD) and Green mode (GRN). These modes effect the core, memory and shader clock, as well as the fan speed and, of course, GPU temperature.

Both the Calibre X250 and X250G work at 738MHz (761MHz in OC mode) for the core, 2200MHz for the memory (2322MHz in OC mode) and 1836MHz for the shader clock (1911MHz for OC mode).

These Calibre cards are unfortunately not yet listed and the price or the availability date haven't been announced.
