Compare any two graphics cards:
GeForce GTS 450 1GB vs GeForce GTX 560
IntroThe GeForce GTS 450 1GB features a GPU core clock speed of 783 MHz, and the 1024 MB of GDDR5 memory is set to run at 902 MHz through a 128-bit bus. It also features 192 Stream Processors, 32 TAUs, and 16 ROPs.
Compare those specifications to the GeForce GTX 560, which comes with a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 memory running at 1001 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 should in theory be much faster than the GeForce GTS 450 1GB in general. (explain)
Texel RateThe GeForce GTX 560 should be a lot (approximately 81%) better at anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateThe GeForce GTX 560 is quite a bit (about 107%) faster with regards to AA than the GeForce GTS 450 1GB, and should be capable of handling higher screen 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.
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 megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, 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 maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
