The GeForce GT 230 was a graphics card by NVIDIA, launched in October 2009. Built on the 55 nm process, and based on the G94B graphics processor, in its G94-300-B1 variant, the card supports DirectX 11.1. Even though it supports DirectX 11, the feature level is only 10_0, which can be problematic with many DirectX 11 & DirectX 12 titles. The G94B graphics processor is an average sized chip with a die area of 196 mm² and 505 million transistors. Unlike the fully unlocked GeForce GT 140 OEM, which uses the same GPU but has all 64 shaders enabled, NVIDIA has disabled some shading units on the GeForce GT 230 to reach the product's target shader count. It features 48 shading units, 24 texture mapping units, and 16 ROPs. NVIDIA has paired 512 MB GDDR3 memory with the GeForce GT 230, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 650 MHz, memory is running at 900 MHz.
Being a single-slot card, the NVIDIA GeForce GT 230 does not require any additional power connector, its power draw is rated at 75 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. GeForce GT 230 is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
