NVIDIA GeForce GT 230 Image NVIDIA G94B Image
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 10.0. 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 placed 512 MB GDDR3 memory on the card, 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.
We recommend the NVIDIA GeForce GT 230 for gaming with highest details at resolutions up to, and including, 1280x720.
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. GeForce GT 230 is connected to the rest of the system using a PCIe 2.0 x16 interface.
