The NVIDIA GeForce 405M is a mobile graphics card that was released on January 5, 2011 and is currently at the end of its production life.
Designed for use in portable devices, the GeForce 405M has a graphics processing unit (GPU) that runs at a clock speed of 606 MHz and a shader clock speed of 1468 MHz. It also has a memory clock speed of 790 MHz and a memory size of 1024 MB, using GDDR3 technology.
With a bus interface of PCIe 2.0 x16 and a memory bus of 64 bit, the GeForce 405M has a bandwidth of 12.64 GB/s. It also has 16 shading units, 8 texture mapping units (TMUs), and 4 render output units (ROPs), as well as 32 KB of L2 cache.
In terms of performance, the GeForce 405M has a theoretical pixel rate of 2.424 GPixel/s and a texture rate of 4.848 GTexel/s. It also has a floating-point processing power of 46.98 GFLOPS.
The graphics card supports DirectX 11.1, OpenGL 3.3, OpenCL 1.1, but does not support Vulkan. It does support CUDA 1.2 and has a shader model of 4.1.
The GeForce 405M is based on the Tesla 2.0 architecture and is produced by TSMC using 40 nm technology. It has a total of 260 million transistors, giving it a density of 4.6 million per mm². The die size of this graphics card is 57 mm² and it comes in a BGA-969 chip package.
The graphics card has a thermal design power (TDP) of 14 W and is powered by the system's integrated graphics processor (IGP), meaning it does not require any additional power connectors.
Overall, the NVIDIA GeForce 405M is a mid-range mobile graphics card with modest performance capabilities that is suitable for use in portable devices. Although it has been discontinued, it is still a viable option for older systems and can handle basic graphics-intensive tasks.
