GeForce GTX 660 vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 memory runs at a speed of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Radeon R7 M260		17160 Mtexels/sec
	Difference: 61240 (357%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 660 is a better choice, by far. (explain)

GeForce GTX 660		23520 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 17800 (311%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 maximum fill rate.
