About the NVIDIA GeForce RTX 4090 Mobile GPU
The NVIDIA GeForce RTX 4090 Mobile is a mobile graphics card that launched in Q1 2023. It is built on the Ada Lovelace GPU microarchitecture (codename AD103) and is manufactured on a 5 nm process.
Memory
The RTX 4090 Mobile has 16 GB of GDDR6 memory, with a 2,250 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 576 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 RTX 4090 Mobile includes 9,728 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,335 MHz and can dynamically boost its clock speed up to 1,695 MHz. Complementing the processing units are 304 texture mapping units (TMUs) for efficient texture filtering and 112 render output units (ROPs) for pixel processing. Additionally, the GPU features 304 tensor cores optimized for AI-accelerated workloads and 76 RT cores dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 120 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The RTX 4090 Mobile has the 14th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 62.10% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
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.
