Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GTX 750
IntroThe GeForce 9800 GT 512MB makes use of a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.
Compare that to the GeForce GTX 750, which uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this specific card. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 750 should be 39% quicker than the GeForce 9800 GT 512MB in general, due to its higher data rate. (explain)
Texel RateThe GeForce 9800 GT 512MB will be a little bit (more or less 3%) better at anisotropic filtering than the GeForce GTX 750. (explain)
Pixel RateThe GeForce GTX 750 will be much (more or less 70%) more effective at AA than the GeForce 9800 GT 512MB, and will be able to handle higher screen resolutions more effectively. (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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If 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 high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
