GeForce GTX 295 vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 should be much faster than the Radeon R7 M260X in general. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 159776 (250%)

Texel Rate

The GeForce GTX 295 should be quite a bit (more or less 365%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 72360 (365%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 295 is superior to the Radeon R7 M260X, by far. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 25656 (389%)

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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling 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 the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
