The NVIDIA GeForce GT 545 is a discrete graphics card that was released on May 14th, 2011. It is based on the Fermi 2.0 architecture and is produced by TSMC using a 40nm process. With a total of 1,170 million transistors and a density of 4.9M/mm², the GT 545 features a die size of 238mm² and comes in a BGA-1337 chip package.
This graphics card has a PCIe 2.0 x16 bus interface and a single-slot design, making it suitable for a variety of computer builds. Its compact length of 145mm and low TDP of 70W also make it an efficient and space-saving option.
The GT 545 is equipped with 3 streaming multiprocessors (SMs) and a total of 144 shading units, 24 texture mapping units (TMUs), and 16 render output units (ROPs). It also has a 64KB L1 and 384KB L2 cache per SM. With these specifications, the GT 545 has a theoretical performance of 4.320 GPixel/s for pixel rendering, 17.28 GTexel/s for texture mapping, and 414.7 GFLOPS for FP32 calculations.
The graphics card comes with 1536MB of DDR3 memory on a 192-bit bus, providing a bandwidth of 38.40GB/s. It has a GPU clock speed of 720MHz, a shader clock speed of 1440MHz, and a memory clock speed of 800MHz.
In terms of graphics features, the GT 545 supports DirectX 12, OpenGL 4.6, OpenCL 1.1, Vulkan, CUDA 2.1, and Shader Model 5.1. It also has a processing power of 414.7 GFLOPS for floating-point calculations and 34.56 GFLOPS for double-precision calculations.
The GT 545 has a suggested power supply unit (PSU) of 250W and no external power connectors, making it easy to install and less power-hungry. It also features 1x DVI output for display.
Despite its impressive specs, the GT 545 has since reached its end-of-life production status, with its original launch price being $149 USD. It also has no predecessor or successor in its product line.
Overall, the NVIDIA GeForce GT 545 is a capable graphics card for its time, offering a good balance of performance, power efficiency, and graphics features. While it may not stand out in terms of performance compared to newer graphics cards, it remains a viable option for budget and compact systems.
