The Arktek GeForce GT 740 (Low Profile, DDR3) is a compact, small-bracket version of NVIDIA's Kepler-architecture GT 740, built specifically to fit slim/small-form-factor desktop cases and low-profile PCI slots where a full-height card physically won't fit. It carries 4GB of DDR3 memory (a lower-bandwidth, lower-cost memory type than the GDDR5 used on the standard-height GT 740 variants elsewhere in this range) on a 128-bit bus — DDR3-equipped GT 740 cards run measurably slower in real-world 3D workloads than their GDDR5 counterparts, since DDR3's lower bandwidth becomes the limiting factor before the GPU core itself does. This makes the card best suited to basic desktop and business use, HTPC video playback, and light 2D/office multitasking in small-form-factor systems, rather than gaming or any bandwidth-sensitive 3D workload. Its low-profile bracket is the real selling point here — it's a rare option for adding real discrete graphics to slim corporate desktops, small-form-factor towers, and thin-client-style chassis that can't accept a standard-height card at all.
