Radeon R7 260X vs Radeon RX 460


Intro

The Radeon R7 260X uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory runs at a speed of 1625 MHz on this particular model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon RX 460, which uses a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this specific model. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

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

Texel Rate

The Radeon R7 260X should be a bit (approximately 1%) more effective at 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 the winner, 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 transported across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
