NVIDIA GeForce GT 555M

NVIDIA GeForce GT 555M Image NVIDIA GF106 Image
The GeForce GT 555M was a graphics card by NVIDIA, launched in March 2011. Built on the 40 nm process, and based on the GF106 graphics processor, the card supports DirectX 11.0. The GF106 graphics processor is an average sized chip with a die area of 238 mm² and 1,170 million transistors. Unlike the fully unlocked GeForce GTS 450, which uses the same GPU but has all 192 shaders enabled, NVIDIA has disabled some shading units on the GeForce GT 555M to reach the product's target shader count. It features 144 shading units, 24 texture mapping units and 24 ROPs. NVIDIA has placed 1,536 MB DDR3 memory on the card, which are connected using a 192-bit memory interface. The GPU is operating at a frequency of 590 MHz, memory is running at 900 MHz.
We recommend the NVIDIA GeForce GT 555M for gaming with highest details at resolutions up to, and including, 800x600.
Its power draw is rated at 35 W maximum. GeForce GT 555M is connected to the rest of the system using a PCIe 2.0 x16 interface.
