Compare any two graphics cards:
GeForce 9800 GTX+ vs Radeon R9 M270X
IntroThe GeForce 9800 GTX+ makes use of a 55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory is set to run at a frequency of 1100 MHz on this specific model. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon R9 M270X, which has a core clock speed of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M270X, in theory, should be just a bit faster than the GeForce 9800 GTX+ in general. (explain)
Texel RateThe GeForce 9800 GTX+ will be quite a bit (about 63%) better at AF than the Radeon R9 M270X. (explain)
Pixel RateThe GeForce 9800 GTX+ will be just a bit (approximately 2%) more effective at AA than the Radeon R9 M270X, and also should be capable of handling higher resolutions without losing too much performance. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units 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 in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
