GeForce GTX 260 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which features core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 TAUs 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 theoretically be 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 much (approximately 66%) better 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

The Radeon RX 460 will be a small bit (more or less 8%) better at AA than the GeForce GTX 260, and should be able to handle higher screen resolutions without losing too much performance. (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 max amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
