Compare any two graphics cards:
GeForce 8300 GS (OEM) vs GeForce GTX 660 Ti
IntroThe GeForce 8300 GS (OEM) has a GPU core speed of 450 MHz, and the 128 MB of DDR2 RAM is set to run at 400 MHz through a 64-bit bus. It also features 8 SPUs, 4 TAUs, and 2 Raster Operation Units.
Compare that to the GeForce GTX 660 Ti, which features a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 192-bit memory bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 660 Ti should be quite a bit faster than the GeForce 8300 GS (OEM) overall. (explain)
Texel RateThe GeForce GTX 660 Ti is a lot (about 5593%) more effective at texture filtering than the GeForce 8300 GS (OEM). (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 660 Ti is superior to the GeForce 8300 GS (OEM), by a large margin. (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 (in units of MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
