Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 features a clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 32 ROPs.
Compare those specs to the Geforce GTX 760, which features a clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The Geforce GTX 760 should in theory be just a bit faster than the Geforce GTX 670 overall. (explain)
Texel RateThe Geforce GTX 670 will be a bit (about 9%) better at AF than the Geforce GTX 760. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Geforce GTX 760 is superior to the Geforce GTX 670, though only just barely. (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 largest amount of information (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher 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 one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
