Compare any two graphics cards:
Geforce GTX 770 vs Geforce GTX 780
IntroThe Geforce GTX 770 uses a 28 nm design. nVidia has clocked the core speed at 1046 MHz. The GDDR5 RAM is set to run at a frequency of 1753 MHz on this particular card. It features 1536 SPUs along with 128 TAUs and 32 ROPs.
Compare those specifications to the Geforce GTX 780, which has a clock frequency of 863 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 384-bit bus, and uses a 28 nm design. It features 2304 SPUs, 192 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 780, in theory, should perform much faster than the Geforce GTX 770 in general. (explain)
Texel RateThe Geforce GTX 780 should be much (more or less 24%) more effective at texture filtering than the Geforce GTX 770. (explain)
Pixel RateThe Geforce GTX 780 is much (more or less 24%) more effective at anti-aliasing than the Geforce GTX 770, and able to handle higher resolutions without slowing down too much. (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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of 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 in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
