Summary
About the NVIDIA GeForce GT 645 (OEM) GPU
The NVIDIA GeForce GT 645 (OEM) is an end-of-life desktop graphics card that released in Q2 2012. It is built on the Fermi 2.0 GPU microarchitecture (codename GF114) and is manufactured on a 40 nm process.
Memory
The GT 645 has 1,024 MB of GDDR5 memory, with a 957 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 91.87 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.
Cores and Clock Speeds
The GT 645 includes 288 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 776 MHz. Complementing the processing units are 48 texture mapping units (TMUs) for efficient texture filtering and 24 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GT 645 occupies 2 PCIe expansion slots. It supports DVI, mini-HDMI 1.3a display connections. NVIDIA recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 102 W.
About the NVIDIA GeForce GTX 645 (OEM) GPU
The NVIDIA GeForce GTX 645 (OEM) is an end-of-life desktop graphics card that released in Q2 2013. It is built on the Kepler GPU microarchitecture (codename GK106S) and is manufactured on a 28 nm process.
Memory
The GTX 645 has 1,024 MB of GDDR5 memory, with a 1,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 64 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.
Cores and Clock Speeds
The GTX 645 includes 576 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 823 MHz. Complementing the processing units are 48 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GTX 645 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. NVIDIA recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 65 W.
