Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 460 (OEM)
IntroThe GeForce GTX 260 has clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 192 SPUs as well as 64 Texture Address Units and 28 Rasterization Operator Units.
Compare that to the GeForce GTX 460 (OEM), which uses a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 RAM works at a speed of 850 MHz on this card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 260 should theoretically be a little bit faster than the GeForce GTX 460 (OEM) in general. (explain)
Texel RateThe GeForce GTX 260 is a bit (approximately 1%) faster with regards to AF than the GeForce GTX 460 (OEM). (explain)
Pixel RateThe GeForce GTX 460 (OEM) will be quite a bit (about 29%) more effective at full screen anti-aliasing than the GeForce GTX 260, and should be able to handle higher screen resolutions without losing too much performance. (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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at 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 the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
