GeForce GTX 260 vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which has core speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
GeForce GTX 260		182 Watts
	Difference: 107 Watts (143%)

Memory Bandwidth

The Radeon RX 460 should in theory perform just a bit faster than the GeForce GTX 260 in general. (explain)

Radeon RX 460		112000 MB/sec
GeForce GTX 260		111888 MB/sec
	Difference: 112 (0%)

Texel Rate

The Radeon RX 460 should be quite a bit (more or less 66%) more effective at anisotropic filtering than the GeForce GTX 260. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 24176 (66%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 460 is superior to the GeForce GTX 260, though not by far. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 1312 (8%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
