Compare any two graphics cards:
VS

GeForce GTX 295 vs Radeon R7 250X 2GB

Intro

The GeForce GTX 295 uses a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this specific card. It features 240 SPUs along with 80 TAUs and 28 Rasterization Operator Units.

Compare all that to the Radeon R7 250X 2GB, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Radeon R7 250X 2GB 72000 MB/sec
Difference: 151776 (211%)

Texel Rate

The GeForce GTX 295 will be a lot (about 130%) more effective at AF than the Radeon R7 250X 2GB. (explain)

GeForce GTX 295 92160 Mtexels/sec
Radeon R7 250X 2GB 40000 Mtexels/sec
Difference: 52160 (130%)

Pixel Rate

The GeForce GTX 295 should be quite a bit (approximately 102%) more effective at full screen anti-aliasing than the Radeon R7 250X 2GB, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon R7 250X 2GB 16000 Mpixels/sec
Difference: 16256 (102%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
