GeForce GTX 460 (OEM) vs Radeon RX 460

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 460 should be 3% quicker than the GeForce GTX 460 (OEM) in general, because of its greater bandwidth. (explain)

Radeon RX 460		112000 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 is quite a bit (approximately 68%) better at anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 24640 (68%)

Pixel Rate

The GeForce GTX 460 (OEM) should be just a bit (more or less 19%) better at anti-aliasing than the Radeon RX 460, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 3360 (19%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
