GeForce GTX Titan vs Radeon R7 M265

Intro

Compare all of that to the Radeon R7 M265, which features GPU core speed of 725 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan will be 801% faster than the Radeon R7 M265 in general, because of its greater bandwidth. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 256384 (801%)

Texel Rate

The GeForce GTX Titan is quite a bit (about 978%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 170088 (978%)

Pixel Rate

The GeForce GTX Titan should be quite a bit (more or less 593%) faster with regards to anti-aliasing than the Radeon R7 M265, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 34376 (593%)

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 max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
