Compare any two graphics cards:
GeForce 8600 GTS vs GeForce GTS 250 1GB
IntroThe GeForce 8600 GTS has a GPU core speed of 675 MHz, and the 512 MB of GDDR3 RAM runs at 1000 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.
Compare all that to the GeForce GTS 250 1GB, which features a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also makes use of a 256-bit bus, and uses a 65/55 nm design. It features 128 SPUs, 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 should be 120% quicker than the GeForce 8600 GTS in general, due to its higher data rate. (explain)
Texel RateThe GeForce GTS 250 1GB should be much (about 337%) more effective at AF than the GeForce 8600 GTS. (explain)
Pixel RateIf using 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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus 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 bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
