Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 has core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 Texture Address Units and 32 ROPs.
Compare all of that to the Geforce GTX 760, which features GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 256-bit bus. It also features 1152 SPUs, 96 Texture Address Units, and 32 ROPs.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Theoretically speaking, the Geforce GTX 760 is 0% faster than the Geforce GTX 670 overall, due to its greater bandwidth. (explain)
Texel RateThe Geforce GTX 670 is just a bit (approximately 9%) faster with regards to AF than the Geforce GTX 760. (explain)
Pixel RateIf running with a high resolution is important to you, then the Geforce GTX 760 is a better choice, but not by far. (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 (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
