Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 780
IntroThe GeForce GTX Titan features core speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 RAM. It features 2688 SPUs along with 224 TAUs and 48 ROPs.
Compare all that to the Geforce GTX 780, which features GPU clock speed of 863 MHz, and 3072 MB of GDDR5 memory set to run at 1502 MHz through a 384-bit bus. It also is made up of 2304 Stream Processors, 192 Texture Address Units, and 48 ROPs.

3DMark Fire Strike
Grand Theft Auto V | 1920x1080 | Very High
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have exactly the same memory bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce GTX Titan will be a little bit (approximately 13%) faster with regards to anisotropic filtering than the Geforce GTX 780. (explain)
Pixel RateIf using a high resolution is important to you, then the Geforce GTX 780 is superior to the GeForce GTX Titan, not by a very large margin though. (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 information (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core 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 per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
