Compare any two graphics cards:
GeForce GTS 250 1GB vs GeForce GTX 460
IntroThe GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory is set to run at a speed of 1100 MHz on this particular model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.
Compare all that to the GeForce GTX 460, which has a core clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 24 Raster Operation Units.

GeForce GTX 460 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce GTX 460 wins overall, by 111 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 GTX 460 should in theory be much faster than the GeForce GTS 250 1GB overall. (explain)
Texel RateThe GeForce GTS 250 1GB should be a lot (about 25%) faster with regards to anisotropic filtering than the GeForce GTX 460. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 460 is superior to the GeForce GTS 250 1GB, 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 within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be processed in one 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 this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
