Radeon R7 260X vs Radeon RX 460

Intro

The Radeon R7 260X has a GPU clock speed of 1100 MHz, and the 2048 MB of GDDR5 memory is set to run at 1625 MHz through a 128-bit bus. It also features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

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

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

Memory Bandwidth

In theory, the Radeon RX 460 should be a small 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 is a little bit (about 1%) faster with regards to texture 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 running with lots of anti-aliasing is important to you, then the Radeon R7 260X is a better choice, but only just. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
