Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon R7 250
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 memory is set to run at a speed of 1026 MHz on this specific model. It features 192 SPUs along with 32 TAUs and 24 ROPs.
Compare those specifications to the Radeon R7 250, which features GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also features 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 550 Ti is 34% faster than the Radeon R7 250 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 550 Ti will be a bit (about 20%) more effective at texture filtering than the Radeon R7 250. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is superior to the Radeon R7 250, and very much so. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
