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 224th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 6.35% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the AMD Radeon R9 M275 GPU
The AMD Radeon R9 M275 is an end-of-life mobile graphics card that released in Q1 2014. It is built on the GCN 1.0 GPU microarchitecture (codename Venus) and is manufactured on a 28 nm process.
Memory
The R9 M275 has 2 GB of GDDR5 memory, with a 1,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 64 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 R9 M275 includes 640 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 900 MHz and can dynamically boost its clock speed up to 925 MHz. Complementing the processing units are 40 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Benchmark Performance
The R9 M275 has the 290th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 3.11% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
