Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs Radeon R9 270X
IntroThe GeForce 9500 GT 1GB GDDR3 features a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon R9 270X, which comes with a GPU core clock speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 1400 MHz through a 256-bit bus. It also is made up of 1280 Stream Processors, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 270X should theoretically be quite a bit faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)
Texel RateThe Radeon R9 270X is a lot (approximately 809%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateThe Radeon R9 270X will be a lot (more or less 627%) more effective at FSAA than the GeForce 9500 GT 1GB GDDR3, and will be capable of handling higher screen resolutions while still performing well. (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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
