GeForce GTX 460 2GB vs Radeon R7 M260

Intro

Compare that to the Radeon R7 M260, which features core clock speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

The GeForce GTX 460 2GB will be much (more or less 120%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 20640 (120%)

Pixel Rate

The GeForce GTX 460 2GB is quite a bit (about 278%) better at AA than the Radeon R7 M260, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 15880 (278%)

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 MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at 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 can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 bandwidth is, the lower the ability to reach the max fill rate.
