Compare any two graphics cards:
VS

GeForce GTX 295 vs Radeon RX 580

Intro

The GeForce GTX 295 features a clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit bus, and uses a 55 nm design. It features 240 SPUs, 80 TAUs, and 28 ROPs.

Compare all of that to the Radeon RX 580, which comes with core speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 580 185 Watts
GeForce GTX 295 289 Watts
Difference: 104 Watts (56%)

Memory Bandwidth

In theory, the Radeon RX 580 should perform a small bit faster than the GeForce GTX 295 overall. (explain)

Radeon RX 580 262144 MB/sec
GeForce GTX 295 223776 MB/sec
Difference: 38368 (17%)

Texel Rate

The Radeon RX 580 is quite a bit (more or less 96%) faster with regards to anisotropic filtering than the GeForce GTX 295. (explain)

Radeon RX 580 181008 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 88848 (96%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 580 is a better choice, and very much so. (explain)

Radeon RX 580 40224 Mpixels/sec
GeForce GTX 295 32256 Mpixels/sec
Difference: 7968 (25%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
