Compare any two graphics cards:
GeForce GT 320 vs GeForce GTX 570
IntroThe GeForce GT 320 makes use of a 40 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 RAM runs at a speed of 790 MHz on this specific card. It features 72 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.
Compare all of that to the GeForce GTX 570, which has clock speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 RAM. It features 480 SPUs as well as 60 TAUs and 40 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 570 should be quite a bit faster than the GeForce GT 320 overall. (explain)
Texel RateThe GeForce GTX 570 will be quite a bit (approximately 239%) more effective at anisotropic filtering than the GeForce GT 320. (explain)
Pixel RateThe GeForce GTX 570 is quite a bit (more or less 578%) more effective at AA than the GeForce GT 320, and able to handle 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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
