GeForce GTX 275 vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which comes with a core clock speed of 715 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 275 should be 694% quicker than the Radeon R7 M260 overall, due to its higher bandwidth. (explain)

GeForce GTX 275		127008 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 111008 (694%)

Texel Rate

The GeForce GTX 275 will be a lot (about 195%) faster with regards to AF than the Radeon R7 M260. (explain)

GeForce GTX 275		50640 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 33480 (195%)

Pixel Rate

The GeForce GTX 275 should be quite a bit (approximately 210%) faster with regards to FSAA than the Radeon R7 M260, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 12004 (210%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
