Compare any two graphics cards:
GeForce 8600 GTS vs GeForce GTS 250 1GB
IntroThe GeForce 8600 GTS makes use of a 80 nm design. nVidia has set the core frequency at 675 MHz. The GDDR3 memory runs at a frequency of 1000 MHz on this specific model. It features 32 SPUs along with 16 TAUs and 8 ROPs.
Compare those specs to the GeForce GTS 250 1GB, which comes with a clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also makes use of a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTS 250 1GB should in theory perform a lot faster than the GeForce 8600 GTS in general. (explain)
Texel RateThe GeForce GTS 250 1GB will be much (more or less 337%) better at texture filtering than the GeForce 8600 GTS. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTS 250 1GB is superior to the GeForce 8600 GTS, by far. (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 information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 applied per second. This number is worked out by multiplying the total texture units 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 in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
