Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon R7 250
IntroThe GeForce GTS 250 512MB comes with a clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon R7 250, which features a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R7 250 should perform just a bit faster than the GeForce GTS 250 512MB overall. (explain)
Texel RateThe GeForce GTS 250 512MB is much (more or less 97%) better at AF than the Radeon R7 250. (explain)
Pixel RateThe GeForce GTS 250 512MB should be a lot (more or less 48%) faster with regards to AA than the Radeon R7 250, and also should be capable of handling higher screen 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
