Radeon R7 260X vs Radeon RX 460

Intro

The Radeon R7 260X features a GPU core speed of 1100 MHz, and the 2048 MB of GDDR5 memory runs at 1625 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Compare all of that to the Radeon RX 460, which comes with a GPU core clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
Radeon R7 260X 115 Watts
Difference: 40 Watts (53%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should be just a bit faster than the Radeon R7 260X in general. (explain)

Radeon RX 460 112000 MB/sec
Radeon R7 260X 104000 MB/sec
Difference: 8000 (8%)

Texel Rate

The Radeon R7 260X will be a small bit (about 1%) more effective at anisotropic filtering than the Radeon RX 460. (explain)

Radeon R7 260X 61600 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 560 (1%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 260X is a better choice, but not by far. (explain)

Radeon R7 260X 17600 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 160 (1%)

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 largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
