GeForce GTX 460 vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which comes with GPU core speed of 1090 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 460		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 2GB should be 30% quicker than the GeForce GTX 460 overall, because of its greater bandwidth. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 25600 (30%)

Texel Rate

The Radeon RX 460 2GB will be a lot (more or less 61%) better at AF than the GeForce GTX 460. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 23240 (61%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 460 2GB is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 1240 (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 (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
