Compare any two graphics cards:
GeForce 8600 GTS vs GeForce GTS 250 1GB
IntroThe GeForce 8600 GTS features core clock speeds of 675 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.
Compare those specs to the GeForce GTS 250 1GB, which uses a 65/55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 RAM works at a frequency of 1100 MHz on this specific card. It features 128 SPUs as well as 64 Texture Address Units 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)
In theory, the GeForce GTS 250 1GB will be 120% faster than the GeForce 8600 GTS overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTS 250 1GB should be a lot (about 337%) faster with regards to texture filtering than the GeForce 8600 GTS. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTS 250 1GB is a better choice, 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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
