Compare any two graphics cards:
GeForce 8600 GTS vs GeForce GTS 250 1GB
IntroThe GeForce 8600 GTS features a clock speed of 675 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.
Compare all that to the GeForce GTS 250 1GB, which comes with a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.
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)
The GeForce GTS 250 1GB, in theory, should be a lot faster than the GeForce 8600 GTS in general. (explain)
Texel RateThe GeForce GTS 250 1GB should be quite a bit (approximately 337%) better at texture filtering than the GeForce 8600 GTS. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTS 250 1GB is superior to the GeForce 8600 GTS, and very much so. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 processed in one second. This number is worked out by multiplying the total 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 most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
