Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 780
IntroThe GeForce GTX Titan uses a 28 nm design. nVidia has clocked the core speed at 837 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this specific card. It features 2688 SPUs along with 224 TAUs and 48 Rasterization Operator Units.
Compare all that to the Geforce GTX 780, which comes with a clock speed of 863 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2304 SPUs, 192 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe GeForce GTX Titan will be a small bit (approximately 13%) more effective at anisotropic filtering than the Geforce GTX 780. (explain)
Pixel RateThe Geforce GTX 780 is a little bit (more or less 3%) better at full screen anti-aliasing than the GeForce GTX Titan, 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.
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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once 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, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
