About the AMD Radeon R9 M390X GPU

The AMD Radeon R9 M390X is an end-of-life mobile graphics card that released in Q2 2015. It is built on the GCN 3.0 GPU microarchitecture (codename Amethyst) and is manufactured on a 28 nm process.

Memory

The R9 M390X has 4 GB of GDDR5 memory, with a 1,250 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 160 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 M390X includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 723 MHz and can dynamically boost its clock speed up to 723 MHz. Complementing the processing units are 128 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 75 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The R9 M390X has the 187th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 9.03% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon R9 M280X GPU

The AMD Radeon R9 M280X is an end-of-life mobile graphics card that released in Q1 2015. It is built on the GCN 2.0 GPU microarchitecture (codename Saturn) and is manufactured on a 28 nm process.

Memory

The R9 M280X has 4 GB of GDDR5 memory, with a 1,375 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 88 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 M280X includes 896 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 1,000 MHz. Complementing the processing units are 56 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 75 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The R9 M280X has the 256th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 4.49% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
