GeForce GTX 295 vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which uses a 28 nm design. AMD has clocked the core speed at 715 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this particular model. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 295 is 1299% quicker than the Radeon R7 M260 overall, because of its higher data rate. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 207776 (1299%)

Texel Rate

The GeForce GTX 295 should be much (approximately 437%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 75000 (437%)

Pixel Rate

The GeForce GTX 295 will be much (approximately 464%) better at full screen anti-aliasing than the Radeon R7 M260, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 26536 (464%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its 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 clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
