Compare any two graphics cards:
GeForce GTX Titan vs Radeon HD 5870
IntroThe GeForce GTX Titan makes use of a 28 nm design. nVidia has set the core frequency at 837 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this model. It features 2688 SPUs along with 224 TAUs and 48 ROPs.
Compare those specifications to the Radeon HD 5870, which makes use of a 40 nm design. ATi has set the core frequency at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this model. It features 1600(320x5) SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX Titan should be quite a bit faster than the Radeon HD 5870 overall. (explain)
Texel RateThe GeForce GTX Titan will be quite a bit (approximately 176%) more effective at AF than the Radeon HD 5870. (explain)
Pixel RateThe GeForce GTX Titan will be much (more or less 48%) better at AA than the Radeon HD 5870, and also capable of handling higher resolutions while still performing well. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units 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 per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
