Geforce GTX 690 vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Geforce GTX 690, in theory, should be much faster than the Radeon R7 M260X in general. (explain)

Geforce GTX 690		384512 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 320512 (501%)

Texel Rate

The Geforce GTX 690 is quite a bit (approximately 1083%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

Geforce GTX 690		234240 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 214440 (1083%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 690 is a better choice, and very much so. (explain)

Geforce GTX 690		58560 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 51960 (787%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
