The Quadro NVS 135M was a professional mobile graphics chip by NVIDIA, launched on May 9th, 2007. Built on the 80 nm process, and based on the G86S graphics processor, in its G86-621-A2 variant, the chip 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 G86S graphics processor is an average sized chip with a die area of 127 mm² and 210 million transistors. It features 16 shading units, 8 texture mapping units, and 4 ROPs. NVIDIA has paired 256 MB GDDR3 memory with the Quadro NVS 135M, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 400 MHz, memory is running at 594 MHz. Its power draw is rated at 10 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Quadro NVS 135M is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
