GeForce GTX 960 vs Radeon RX 460

Intro

The GeForce GTX 960 has a GPU clock speed of 1127 MHz, and the 2048 MB of GDDR5 memory is set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon RX 460, which uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this specific card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
GeForce GTX 960 120 Watts
Difference: 45 Watts (60%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce GTX 960 should be a little bit (about 18%) better at anisotropic filtering than the Radeon RX 460. (explain)

GeForce GTX 960 72128 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 11088 (18%)

Pixel Rate

The GeForce GTX 960 will be quite a bit (approximately 107%) better at anti-aliasing than the Radeon RX 460, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960 36064 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 18624 (107%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
