Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 features a core clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 32 ROPs.
Compare all that to the Geforce GTX 760, which has a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also features 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Theoretically, the Geforce GTX 760 should perform a small bit faster than the Geforce GTX 670 overall. (explain)
Texel RateThe Geforce GTX 670 will be just a bit (about 9%) faster with regards to anisotropic filtering than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 760 is a little bit (approximately 7%) better at FSAA than the Geforce GTX 670, and 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, 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 number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
