About the AMD Radeon R9 M385X GPU

The AMD Radeon R9 M385X is an end-of-life mobile graphics card that released in Q2 2015. It is built on the GCN 2.0 GPU microarchitecture (codename Strato) and is manufactured on a 28 nm process.

Memory

The R9 M385X has 4 GB of GDDR5 memory, with a 1,200 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 76.8 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 R9 M385X includes 896 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,000 MHz and can dynamically boost its clock speed up to 1,100 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 M385X has the 234th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 5.27% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon R9 280X GPU

The AMD Radeon R9 280X is an end-of-life desktop graphics card that released in Q4 2013 with a MSRP of $299. It is built on the GCN 1.0 GPU microarchitecture (codename Tahiti) and is manufactured on a 28 nm process.

Memory

The R9 280X has 3 GB of GDDR5 memory, with a 1,500 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 288 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 280X includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 850 MHz and can dynamically boost its clock speed up to 1,000 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 R9 280X occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. AMD recommends a power supply of at least 600 W to handle the GPU's thermal design power (TDP) of 250 W.

Benchmark Performance & Value

The R9 280X has the 171st best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 10.32% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 10,792 score and $299 launch price (MSRP) gives it a performance per dollar of 36.09. This is the 73rd best in value for the 3DMark 11 Performance GPU benchmark.
