Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 5870
IntroThe GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has clocked the core speed at 783 MHz. The GDDR5 memory works at a speed of 902 MHz on this specific card. It features 192 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.
Compare those specifications to the Radeon HD 5870, which comes with a GPU core clock speed of 850 MHz, and 1024 MB of GDDR5 memory set to run at 1200 MHz through a 256-bit bus. It also features 1600(320x5) Stream Processors, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 5870 should in theory be much superior to the GeForce GTS 450 1GB in general. (explain)
Texel RateThe Radeon HD 5870 should be quite a bit (approximately 171%) faster with regards to anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5870 is superior to the GeForce GTS 450 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.
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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant 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.
