Compare any two graphics cards:
GeForce 8600 GTS vs GeForce GTS 250 1GB
IntroThe GeForce 8600 GTS has 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 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.
Compare that to the GeForce GTS 250 1GB, which features core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator 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 120% quicker than the GeForce 8600 GTS in general, due to its greater data rate. (explain)
Texel RateThe GeForce GTS 250 1GB will be quite a bit (approximately 337%) faster with regards to AF than the GeForce 8600 GTS. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTS 250 1GB is superior to the GeForce 8600 GTS, 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 max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 by the core speed of the chip. The higher this number, 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 number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 memory bandwidth is, the lower the potential to get to the maximum fill rate.
