The GeForce GT 730 was a graphics card by NVIDIA, launched on June 18th, 2014. Built on the 28 nm process, and based on the GK208B graphics processor, in its GK208-302-B1 variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GK208B graphics processor is a relatively small chip with a die area of only 87 mm² and 1,020 million transistors. It features 384 shading units, 32 texture mapping units, and 8 ROPs. NVIDIA has paired 1,024 MB GDDR5 memory with the GeForce GT 730, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 902 MHz, memory is running at 1253 MHz (5 Gbps effective).
Being a single-slot card, the NVIDIA GeForce GT 730 does not require any additional power connector, its power draw is rated at 38 W maximum. Display outputs include: 1x DVI, 1x HDMI 1.4a, 1x VGA. GeForce GT 730 is connected to the rest of the system using a PCI-Express 2.0 x8 interface. The card measures 145 mm in length, and features a single-slot cooling solution.
