Geforce GTX 680 vs Radeon R9 270X

Intro

Compare those specs to the Radeon R9 270X, which comes with a GPU core clock speed of 1000 MHz, and 2048 MB of GDDR5 memory running at 1400 MHz through a 256-bit bus. It also is made up of 1280 Stream Processors, 80 TAUs, and 32 Raster Operation Units.

Geforce GTX 680		195 Watts
	Difference: 15 Watts (8%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 680 should be 7% quicker than the Radeon R9 270X in general, because of its greater bandwidth. (explain)

Geforce GTX 680		192256 MB/sec
Radeon R9 270X		179200 MB/sec
	Difference: 13056 (7%)

Texel Rate

The Geforce GTX 680 should be quite a bit (more or less 61%) faster with regards to anisotropic filtering than the Radeon R9 270X. (explain)

Geforce GTX 680		128768 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 48768 (61%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 680 is the winner, but it probably won't make a huge difference. (explain)

Geforce GTX 680		32192 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 192 (1%)

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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the 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 maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
