Compare any two graphics cards:
GeForce 8600 GTS vs GeForce GTS 250 1GB
IntroThe GeForce 8600 GTS features a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 memory is set to run at 1000 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 ROPs.
Compare those specifications to the GeForce GTS 250 1GB, which comes with GPU clock speed of 738 MHz, and 1024 MB of GDDR3 memory running at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.
GeForce GTS 250 1GB wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce GTS 250 1GB wins overall, by 110 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTS 250 1GB should be quite a bit faster than the GeForce 8600 GTS overall. (explain)
Texel RateThe GeForce GTS 250 1GB will be much (approximately 337%) more effective at AF than the GeForce 8600 GTS. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTS 250 1GB is a better choice, 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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
