Compare any two graphics cards:
GeForce GTX 560 vs Geforce GTX 760
IntroThe GeForce GTX 560 comes with a GPU clock speed of 810 MHz, and the 1024 MB of GDDR5 memory runs at 1001 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.
Compare those specifications to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this specific card. It features 1152 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Geforce GTX 760 should be much faster than the GeForce GTX 560 overall. (explain)
Texel RateThe Geforce GTX 760 will be a lot (approximately 107%) faster with regards to anisotropic filtering than the GeForce GTX 560. (explain)
Pixel RateThe Geforce GTX 760 will be a lot (more or less 21%) more effective at FSAA than the GeForce GTX 560, and should be capable of handling higher resolutions better. (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 over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 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 clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a 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 figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
