Compare any two graphics cards:
Geforce GTX 770 vs Geforce GTX 780
IntroThe Geforce GTX 770 makes use of a 28 nm design. nVidia has set the core frequency at 1046 MHz. The GDDR5 memory is set to run at a frequency of 1753 MHz on this specific card. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.
Compare those specs to the Geforce GTX 780, which comes with core speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 RAM. It features 2304 SPUs as well as 192 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Performance-wise, the Geforce GTX 780 should theoretically be quite a bit superior to the Geforce GTX 770 overall. (explain)
Texel RateThe Geforce GTX 780 is a lot (approximately 24%) better at texture filtering than the Geforce GTX 770. (explain)
Pixel RateThe Geforce GTX 780 will be a lot (about 24%) better at anti-aliasing than the Geforce GTX 770, and also capable of handling higher 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 (measured in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
