About the NVIDIA GeForce GT 425M GPU
The NVIDIA GeForce GT 425M is an end-of-life mobile graphics card that released in Q3 2010. It is built on the Fermi GPU microarchitecture (codename GF108) and is manufactured on a 40 nm process.
Memory
The GT 425M has 1,024 MB of DDR3 memory, with a 800 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 25.6 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 425M includes 96 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 560 MHz. Complementing the processing units are 16 texture mapping units (TMUs) for efficient texture filtering and 4 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 23 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 425M has the 484th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.72% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the NVIDIA GeForce 840M GPU
The NVIDIA GeForce 840M is an end-of-life mobile graphics card that released in Q1 2014. It is built on the Maxwell GPU microarchitecture (codename GM108S) and is manufactured on a 28 nm process.
Memory
The 840M has 2 GB of DDR3 memory, with a 1,001 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 16.02 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 840M includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,029 MHz and can dynamically boost its clock speed up to 1,124 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 33 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The 840M has the 340th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.24% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
