Compare any two graphics cards:
GeForce GT 430 vs Radeon R7 250
IntroThe GeForce GT 430 makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific card. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.Compare those specs to the Radeon R7 250, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a frequency of 1150 MHz on this card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R7 250 should be quite a bit faster than the GeForce GT 430 in general. (explain)
Texel RateThe Radeon R7 250 should be much (about 114%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)
Pixel RateThe Radeon R7 250 is quite a bit (approximately 186%) better at AA than the GeForce GT 430, and will be able to handle higher resolutions better. (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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
