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 AMD Radeon R7 M340 GPU
The AMD Radeon R7 M340 is an end-of-life mobile graphics card that released in Q2 2015. It is built on the GCN 3.0 GPU microarchitecture (codename Meso) and is manufactured on a 28 nm process.
Memory
The R7 M340 has 2 GB of DDR3 memory, with a 1,000 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 16 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 R7 M340 includes 320 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 943 MHz and can dynamically boost its clock speed up to 1,021 MHz. Complementing the processing units are 20 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.
Benchmark Performance
The R7 M340 has the 352nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.05% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
