Nvidia launched there GTX 950 card last week at 150$ which was a pretty good deal, considering the price performance ratio and Nvidia's old offering 750ti in the price range which had been around since a long time and was getting a stiff competition from Amd's new launches. Colorful iGame have also designed there non-reference which is currently only available to testers and showed pretty amazing overclocking performance.
Colorful iGame GTX 950 OC is based on the GM-206-250-A1 Graphic core which features 768 CUDA Cores, 48 Texture Mapping Units and 32 Raster operation units. The card runs at 1140Mhz base and 1329Mhz Boost clock on the overclocked bios in comparison to 1026Mhz base and 1190Mhz boost clock of the reference bios version. The card consists of a 2GB GDDR5 memory which runs along a 128 bit interface and has a TDP of 90Watts. The card while running on the overclocked bios has a TDP of 110Watts which is 20Watts higher than the reference version. The card is available for a 20$ premium price of 179$ in comparison to 159$ of the reference version.
The card is cooled with dual fan cooler which consists of a small aluminium block and uses a single copper pipe to dispose of heat from the GPU block. The card comes with a standard back plate and uses a single 6pin powerconnector to draw in power. The card comes with a switch to switch between the overclocked and normal bios. Display ports consist of a DVI, HDMI and three display ports.
Overclocking And Performance-
At the overclocked bios setting the card performance close to the GTX 760 and 15% slower than the 960 and mostly in par with the Radeon 370. The card turns out to be a heavy overclocker, users managed to overclock the card to insane speed at 1506Mhz core clock and 2004.8Mhz Memory clock speed which is effectively 8.0Ghz clock speed without any voltage adjustments. At this oc configuration the card draws 171Watts power in comparison to 162Watts of the Overclocked bios and 154Watts of the reference bios. At this configuration the card is 2-5% faster than the GTX 760 and 7-10% slower than an overclocked GTX 960. At full load the temperatures didn't cross the 70C mark.
With the small increase in voltage of 1.2v users managed to overclock the card to insane speeds of 1600Mhz core clock and 2000Mhz Memory Clock Speeds. The temperatures in this configuration too didn't cross the 70C marks.
