About the AMD Radeon HD 6470M GPU

The AMD Radeon HD 6470M is an end-of-life mobile graphics card that released in Q1 2011. It is built on the TeraScale 2 GPU microarchitecture (codename Seymour) and is manufactured on a 40 nm process.

Memory

The HD 6470M has 512 MB of DDR3 memory, with a 800 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 12.8 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 HD 6470M includes 160 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 700 MHz. Complementing the processing units are 8 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 25 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The HD 6470M has the 511th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.51% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the NVIDIA GeForce GT 420M GPU

The NVIDIA GeForce GT 420M 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 420M 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 420M includes 96 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 500 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 420M has the 490th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.65% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
