There may be customizations made to the Sparkle's Titan by its manufacturer.
Are the Intel® Branded Intel® ARC™ A750 Card and SPARKLE* Intel® ARC™ A750 Titan Card the same?
Both graphics cards incorporate the Intel® ARC™ A750 chipset. Performance and features are the same between the two. However, being the Sparkle's Titan an Original Equipment Manufacturer (OEM) add-in card, there may be customizations made by the OEM that will make it slightly different from the Intel Branded Card, such as number of HDMI vs DP ports, size and quantity of fans and cooling solution or LED lights.
