Technical specs

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Competitors of Radeon RX 460 1024SP from NVIDIA

We believe that the nearest equivalent to Radeon RX 460 1024SP from NVIDIA is GeForce GTX 960.

Here are some closest NVIDIA rivals to Radeon RX 460 1024SP:

Advantages of AMD Radeon R9 390 X2

Wider memory bus (512 vs 128 bit)

More pipelines (2560 vs 1024)

Higher memory bandwidth (345.6 vs 112 GB/s)

Advantages of AMD Radeon RX 460 1024SP

Much newer (17 January 2017 vs 3 September 2015)

Finer manufacturing process technology (14 vs 28 nm)

Lower power consumption (75W vs 580W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.
