Compare any two graphics cards:
GeForce 8800 GTS (G92) vs GeForce 9800 GTX+
IntroThe GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM is set to run at a frequency of 970 MHz on this specific card. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.
Compare that to the GeForce 9800 GTX+, which comes with clock speeds of 738 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 9800 GTX+ should in theory be a bit superior to the GeForce 8800 GTS (G92) in general. (explain)
Texel RateThe GeForce 9800 GTX+ will be just a bit (more or less 14%) better at AF than the GeForce 8800 GTS (G92). (explain)
Pixel RateThe GeForce 9800 GTX+ is a little bit (about 14%) better at FSAA than the GeForce 8800 GTS (G92), and also 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 largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
