Compare any two graphics cards:
GeForce GTX 570 vs Geforce GTX 760
IntroThe GeForce GTX 570 features a GPU clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM is set to run at 950 MHz through a 320-bit bus. It also features 480 Stream Processors, 60 Texture Address Units, and 40 Raster Operation Units.
Compare all of that to the Geforce GTX 760, which has GPU core speed of 980 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also features 1152 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Geforce GTX 760 should in theory be quite a bit superior to the GeForce GTX 570 overall. (explain)
Texel RateThe Geforce GTX 760 should be a lot (more or less 114%) better at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateThe Geforce GTX 760 will be a little bit (approximately 7%) faster with regards to FSAA than the GeForce GTX 570, and will be able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many 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.
