Compare any two graphics cards:
GeForce GTX 570 vs Geforce GTX 760
IntroThe GeForce GTX 570 uses a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 RAM runs at a frequency of 950 MHz on this specific card. It features 480 SPUs along with 60 TAUs and 40 Rasterization Operator Units.
Compare those specifications 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 is comprised of 1152 SPUs, 96 Texture Address Units, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Geforce GTX 760 should theoretically be a lot superior to the GeForce GTX 570 overall. (explain)
Texel RateThe Geforce GTX 760 is quite a bit (more or less 114%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateThe Geforce GTX 760 will be a little bit (more or less 7%) better at FSAA than the GeForce GTX 570, and also capable of handling higher resolutions without slowing down too much. (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 data (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of 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 processed per second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
