About the AMD Radeon 660M GPU

The AMD Radeon 660M is a mobile graphics card that launched in Q1 2022. It is built on the RDNA 2.0 GPU microarchitecture (codename Rembrandt) and is manufactured on a 6 nm process.

Cores and Clock Speeds

The 660M includes 384 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,500 MHz and can dynamically boost its clock speed up to 1,900 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing. Additionally, the GPU features 6 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 40 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The 660M has the 223rd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 6.45% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon Pro 455 GPU

The AMD Radeon Pro 455 is a mobile graphics card that launched in Q4 2016. It is built on the GCN 4.0 GPU microarchitecture (codename Baffin) and is manufactured on a 14 nm process.

Memory

The Pro 455 has 2 GB of GDDR5 memory, with a 1,270 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 81.28 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 Pro 455 includes 768 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 855 MHz. Complementing the processing units are 48 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 35 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The Pro 455 has the 236th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 5.15% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
