NVIDIA GeForce GT 445M is a high-performance graphics card designed for mobile use. It was released on September 3rd, 2010 and is based on the Fermi architecture, manufactured by TSMC on a 40nm process. With a total of 1,170 million transistors, a density of 4.9M/mm² and a die size of 238 mm², it offers powerful graphics processing capabilities in a compact package.
The graphics processor (GPU) of the NVIDIA GeForce GT 445M is the N11E-GE-A1 variant. It has a core clock speed of 570 MHz and a shader clock speed of 1140 MHz, providing swift and smooth performance for graphic-intensive tasks. The GPU is accompanied by 1024 MB of GDDR5 memory, which has a bandwidth of 40.00 GB/s and is connected to the chip via a 128-bit memory bus.
The rendering configuration of the NVIDIA GeForce GT 445M consists of 144 shading units, 24 texture mapping units (TMUs), and 16 raster operation pipelines (ROPs). These components work together to deliver a pixel rate of 3.420 GPixel/s and a texture rate of 13.68 GTexel/s. The GPU also has 3 streaming multiprocessors (SMs), each with 64 KB of L1 cache and a shared 256 KB of L2 cache.
Theoretical performance calculations show that the NVIDIA GeForce GT 445M can achieve 328.3 GFLOPS of single-precision (FP32) floating-point operations and 27.36 GFLOPS of double-precision (FP64) floating-point operations. This makes it a suitable choice for tasks such as 3D rendering, video editing, and gaming.
In terms of graphics features, the NVIDIA GeForce GT 445M supports DirectX 12, OpenGL 4.6, OpenCL 1.1, and Shader Model 5.1. It does not support Vulkan, but it offers compatibility with CUDA 2.1 for improved performance in GPU-accelerated applications. The graphics card is also capable of driving displays with resolutions up to 3840x2160.
The NVIDIA GeForce GT 445M has a thermal design power (TDP) of 35W and does not require any external power connectors. It draws all its power from the PCIe 2.0 x16 bus, making it an ideal choice for portable devices. The exact number and type of outputs vary depending on the device it is installed in.
Overall, the NVIDIA GeForce GT 445M offers impressive performance and features for a mobile graphics card. However, it has since reached its end-of-life production and has been succeeded by newer models in the NVIDIA GeForce GT series. Nonetheless, it remains a capable option for users looking for a powerful graphics card for their mobile devices.
