AMD Radeon R9 380 vs AMD Radeon R9 M390 (Mac Edition)

The AMD Radeon R9 380 is an end-of-life desktop graphics card that released in Q2 2015 with a MSRP of $199. It is built on the GCN 3.0 GPU microarchitecture (codename Antigua) and is manufactured on a 28 nm process.

Memory

The R9 380 has 2 GB of GDDR5 memory, with a 1,375 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 176 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 380 includes 1,792 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 970 MHz. Complementing the processing units are 112 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The R9 380 occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. AMD recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 190 W.

Benchmark Performance & Value

The R9 380 has the 160th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 11.66% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 12,191 score and $199 launch price (MSRP) gives it a performance per dollar of 61.26. This is the 53rd best in value for the 3DMark 11 Performance GPU benchmark.
