Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon R7 250
IntroThe GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this model. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.
Compare those specs to the Radeon R7 250, which features a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon R7 250 should perform a lot faster than the GeForce GT 240 GDDR5 in general. (explain)
Texel RateThe Radeon R7 250 is much (more or less 36%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R7 250 is the winner, by a large margin. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
