Compare any two graphics cards:
GeForce GT 320 vs Radeon R7 250
IntroThe GeForce GT 320 features a core clock frequency of 540 MHz and a GDDR3 memory speed of 790 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 72 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon R7 250, which has GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250 should be 191% quicker than the GeForce GT 320 overall, due to its greater data rate. (explain)
Texel RateThe Radeon R7 250 should be a lot (approximately 85%) more effective at texture filtering than the GeForce GT 320. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R7 250 is a better choice, by far. (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 (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.
