About the NVIDIA GeForce 820M GPU

The NVIDIA GeForce 820M is an end-of-life mobile graphics card that released in Q4 2013. It is built on the Fermi 2.0 GPU microarchitecture (codename GF117B) and is manufactured on a 28 nm process.

Memory

The 820M has 2 GB of DDR3 memory, with a 900 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 14.4 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 820M includes 96 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 625 MHz. Complementing the processing units are 16 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 15 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The 820M has the 425th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.21% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the NVIDIA GeForce GT 755M GPU

The NVIDIA GeForce GT 755M is an end-of-life mobile graphics card that released in Q2 2013. It is built on the Kepler GPU microarchitecture (codename GK107) and is manufactured on a 28 nm process.

Memory

The GT 755M has 2 GB of GDDR5 memory, with a 1,350 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 86.4 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 GT 755M includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 980 MHz and can dynamically boost its clock speed up to 1,020 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 50 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GT 755M has the 311th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.68% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
