GeForce GTX 285 1GB vs Radeon R7 M260

Intro

Compare that to the Radeon R7 M260, which has a core clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Radeon R7 M260		16000 MB/sec
	Difference: 142976 (894%)

Texel Rate

The GeForce GTX 285 1GB will be much (about 202%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 34680 (202%)

Pixel Rate

The GeForce GTX 285 1GB is a lot (approximately 263%) better at AA than the Radeon R7 M260, and able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 15016 (263%)

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

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
