GeForce GTX 460 SE vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this specific model. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

GeForce GTX 460 SE		108800 MB/sec
	Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 will be quite a bit (about 96%) faster with regards to anisotropic filtering than the GeForce GTX 460 SE. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 29840 (96%)

Pixel Rate

The GeForce GTX 460 SE is a small bit (approximately 19%) more effective at AA than the Radeon RX 460, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 460 SE		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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
