GeForce GTX 275 vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which uses a 28 nm design. AMD has set the core frequency at 725 MHz. The DDR3 memory works at a frequency of 1000 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 275 is 297% faster than the Radeon R7 M265 in general, because of its higher bandwidth. (explain)

GeForce GTX 275		127008 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 95008 (297%)

Texel Rate

The GeForce GTX 275 is quite a bit (approximately 191%) better at texture filtering than the Radeon R7 M265. (explain)

GeForce GTX 275		50640 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 33240 (191%)

Pixel Rate

The GeForce GTX 275 should be quite a bit (approximately 206%) more effective at FSAA than the Radeon R7 M265, and also able to handle higher resolutions more effectively. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 11924 (206%)

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
