GeForce GTX 260 216SP 55 nm vs Radeon R7 M260

Intro

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

Radeon R7 M260		17160 Mtexels/sec
	Difference: 24312 (142%)

Pixel Rate

The GeForce GTX 260 216SP 55 nm should be quite a bit (approximately 182%) better at FSAA than the Radeon R7 M260, and also will be able to handle higher resolutions better. (explain)

GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 10408 (182%)

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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
