GeForce GTX 960 vs Radeon RX 460

Intro

The GeForce GTX 960 features a GPU core clock speed of 1127 MHz, and the 2048 MB of GDDR5 RAM 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 Raster Operation Units.

Compare those specs to the Radeon RX 460, which comes with GPU core speed of 1090 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

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 the exact same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GTX 960 will be a bit (approximately 18%) better at AF 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 should be a lot (approximately 107%) more effective at FSAA than the Radeon RX 460, and also able to handle higher resolutions better. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
