Calibre X460G Extra Features:

Overclock Features Brings Unbeatable DX11 Performance To Mainstream Market

Compared with ordinary GeForce GTX 460 graphics cards on market, the Calibre X460G Graphics Card is overclocked out of box. With 790MHz core speed, 3900MHz memory speed and 1580MHz shader clock, it has 17% performance upgrade and take mainstream gamers' DirectX 11 gaming beyond HD.

Excellent Cooling With Arctic Cooling Solution

The Calibre X460G Graphics Card is equipped with the Accelero Cooling Solution from Arctic Cooling, which delivers ultimate cooling weapon for mainstream hardcore gamers. The Accelero Cooling Solution for the Calibre X460G Graphics Card features 4 pure copper heatpipes with 6mm diameter,2 big size PWM fans with 92mm diameter and pure aluminum fins . The radical optimized air flow design is targeting to cool effectively. The Accelero Cooling Solution can adjust the rotating speed of the fans according to the GPU working temperature, dramatically improve the cooling performance up to 12% between the Calibre X460 cooling system and the stock cooler, delivering more performance and has a higher tolerance for overclocking.The two PWM fans from Accelero cooling solution bring maximum air flow but operate extremely silence.

Calibre 3-years International Warranty

SPARKLE Computer Co., Ltd, is continuously improving product and service quality. High quality components are used for the Calibre X460G Graphics Card to ensure 3 years of reliable performance.

Calibre X456G Graphics Cards Comes with 3 free Applications Bundled

MAGIX Video Easy, which is the first video editing program for the whole family. It's so easy to use that even beginners without any prior skills will be able to design breathtaking videos in just a short time. Transform recordings of family celebrations, vacations, or special events into video DVDs or present your videos on the Internet with ease.

Calibre X460G also offer Supersonic Sled and Design Garage,2 new, exciting NVIDIA applications which showcase how GeForce and these new products are driving the future of gaming. Supersonic Sled is a timed race game involving a rocket-driven sled on a 6-mile track. It provides a compelling and interactive showcase of DX11 Tessellation, PhysX, CUDA particles, and fluid simulation. Design Garage is new, exciting demonstration of ray tracing technology. Interact with the most exclusive vehicles on the road and create incredibly photo-realistic images. Harness every last bit of GF104 compute power using CUDA accelerated ray tracing.

With these two applications, SPARKLE wants to literally give consumers the keys to the new GF104 architecture. To expose and showcase the new level of interactivity and realism that this architecture enables. Applications so compelling that consumers will spend hours playing with.




The mid-range GTX 460 is another Fermi GPU from Nvidia; the GPU is redesigned compared to the older 480, 470 or 465 GTX cards, so now we are dealing with a smaller chip, which is implicitly less complicated to manufacture, would get better yields and it also dissipates less heat.

After the cards were launched, we could see two versions entering the market, a cheaper one with 768MB and another with 1024MB. The Calibre X460G is an overclocked 1Gb unit:


GT104 Block Diagram

Compared with the GF100, the GF104 has only 2 Graphics processing clusters (instead of 4); this traduces in a number of shader multiprocessors cut to a total of eight. Also, the GF104 has only half number of raster and poly-morph engines compared to the GF100.

The memory controllers have also been reduced, from six to two.



However, if we look with more attention on the representation of a SM unit, we can count a total of 48 CUDA cores, opposed to 32 that were in the GF100.

The number of texture units in the SM have been doubled to eight and this gives the GF104 faster texturing capabilities.
