GeForce GTX 460 2GB vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which features a GPU core clock speed of 725 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also features 384 SPUs, 24 TAUs, and 8 ROPs.

Radeon R7 M265		17400 Mtexels/sec
	Difference: 20400 (117%)

Pixel Rate

The GeForce GTX 460 2GB should be much (approximately 272%) more effective at AA than the Radeon R7 M265, and will be able to handle higher resolutions better. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 15800 (272%)

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 max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This figure is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
