Compare any two graphics cards:
VS

GeForce GTX 980M vs Radeon R9 M290X

Intro

The GeForce GTX 980M has core clock speeds of 1038 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1536 SPUs along with 96 Texture Address Units and 64 ROPs.

Compare all of that to the Radeon R9 M290X, which features a clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon R9 M290X, in theory, should perform a bit faster than the GeForce GTX 980M in general. (explain)

Radeon R9 M290X 153600 MB/sec
GeForce GTX 980M 128000 MB/sec
Difference: 25600 (20%)

Texel Rate

The GeForce GTX 980M should be quite a bit (approximately 47%) better at AF than the Radeon R9 M290X. (explain)

GeForce GTX 980M 99648 Mtexels/sec
Radeon R9 M290X 68000 Mtexels/sec
Difference: 31648 (47%)

Pixel Rate

The GeForce GTX 980M should be much (approximately 144%) faster with regards to FSAA than the Radeon R9 M290X, and should be able to handle higher resolutions better. (explain)

GeForce GTX 980M 66432 Mpixels/sec
Radeon R9 M290X 27200 Mpixels/sec
Difference: 39232 (144%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
