Compare any two graphics cards:
GeForce GTX 275 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 275 has a core clock speed of 633 MHz and a GDDR3 memory frequency of 1134 MHz. It also features a 448-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 28 ROPs.
Compare those specs to the GeForce GTX 560 Ti, which features GPU core speed of 822 MHz, and 1024 MB of GDDR5 RAM set to run at 1002 MHz through a 256-bit bus. It also is made up of 384 SPUs, 64 TAUs, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 560 Ti should theoretically be a bit better than the GeForce GTX 275 overall. (explain)
Texel RateThe GeForce GTX 560 Ti is a bit (about 4%) faster with regards to texture filtering than the GeForce GTX 275. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (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 (measured in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once 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, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 fill 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 reach the maximum fill rate.
