AMD Radeon R9 M390 (Mac Edition) vs NVIDIA GeForce GTX 980

The NVIDIA GeForce GTX 980 is an end-of-life desktop graphics card that released in Q3 2014 with a MSRP of $549. It is built on the Maxwell 2.0 GPU microarchitecture (codename GM204) and is manufactured on a 28 nm process.

Memory

The GTX 980 has 4 GB of GDDR5 memory, with a 1,753 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 224.4 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 GTX 980 includes 2,048 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,127 MHz and can dynamically boost its clock speed up to 1,216 MHz. Complementing the processing units are 128 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GTX 980 occupies 2 PCIe expansion slots. It supports DVI, HDMI 2.0, DisplayPort 1.2 display connections. NVIDIA recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 165 W.

Benchmark Performance & Value

The GTX 980 has the 127th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 16.81% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 17,604.5 score and $549 launch price (MSRP) gives it a performance per dollar of 32.07. This is the 76th best in value for the 3DMark 11 Performance GPU benchmark.
