About the NVIDIA TITAN X (Pascal) GPU
The NVIDIA TITAN X (Pascal) is an end-of-life desktop graphics card that released in Q3 2016 with a MSRP of $1,199. It is built on the Pascal GPU microarchitecture (codename GP102) and is manufactured on a 16 nm process.
Memory
The TITAN X has 12 GB of GDDR5X memory, with a 1,251 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 480.4 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 TITAN X includes 3,584 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,417 MHz and can dynamically boost its clock speed up to 1,531 MHz. Complementing the processing units are 224 texture mapping units (TMUs) for efficient texture filtering and 96 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The TITAN X occupies 2 PCIe expansion slots. It supports 1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 600 W to handle the GPU's thermal design power (TDP) of 250 W.
Benchmark Performance & Value
The TITAN X has the 55th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 34.37% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 35,995 score and $1,199 launch price (MSRP) gives it a performance per dollar of 30.02. This is the 79th best in value for the 3DMark 11 Performance GPU benchmark.
About the NVIDIA GeForce GT 645M GPU
The NVIDIA GeForce GT 645M is an end-of-life mobile graphics card that released in Q4 2012. It is built on the Kepler GPU microarchitecture (codename GK107) and is manufactured on a 28 nm process.
Memory
The GT 645M has 2 GB of DDR3 memory, with a 900 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 28.8 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 645M includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 709 MHz and can dynamically boost its clock speed up to 780 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 32 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 645M has the 372nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.76% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
