The GeForce 8400 GS Rev. 3 was a graphics card by NVIDIA, launched on July 12th, 2010. Built on the 40 nm process, and based on the GT218S graphics processor, in its 8400GS-225-B1 variant, the card supports DirectX 11.1. Even though it supports DirectX 11, the feature level is only 10_1, which can be problematic with many DirectX 11 & DirectX 12 titles. The GT218S graphics processor is a relatively small chip with a die area of only 57 mm² and 260 million transistors. Unlike the fully unlocked GeForce 8400 GS PCI Rev. 2, which uses the same GPU but has all 16 shaders enabled, NVIDIA has disabled some shading units on the GeForce 8400 GS Rev. 3 to reach the product's target shader count. It features 8 shading units, 4 texture mapping units, and 4 ROPs. NVIDIA has paired 512 MB DDR2 memory with the GeForce 8400 GS Rev. 3, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 520 MHz, memory is running at 400 MHz. Being a single-slot card, the NVIDIA GeForce 8400 GS Rev. 3 does not require any additional power connector, its power draw is rated at 25 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. GeForce 8400 GS Rev. 3 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 170 mm in length, and features a single-slot cooling solution.
