Compare any two graphics cards:
GeForce GTX 295 vs GeForce GTX Titan
IntroThe GeForce GTX 295 makes use of a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM is set to run at a speed of 999 MHz on this particular card. It features 240 SPUs along with 80 Texture Address Units and 28 ROPs.
Compare all of that to the GeForce GTX Titan, which has a core clock speed of 837 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2688 SPUs, 224 TAUs, and 48 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX Titan should perform much faster than the GeForce GTX 295 overall. (explain)
Texel RateThe GeForce GTX Titan will be much (approximately 103%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)
Pixel RateThe GeForce GTX Titan will be much (about 25%) faster with regards to full screen anti-aliasing than the GeForce GTX 295, and will be capable of handling higher resolutions without slowing down too much. (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.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.
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 (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should 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, 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 clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
