Compare any two graphics cards:
GeForce GT 315 vs GeForce GTX 560
IntroThe GeForce GT 315 features clock speeds of 625 MHz on the GPU, and 790 MHz on the 512 MB of DDR3 memory. It features 48 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.
Compare that to the GeForce GTX 560, which uses a 40 nm design. nVidia has clocked the core speed at 810 MHz. The GDDR5 RAM runs at a speed of 1001 MHz on this particular card. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 560 should theoretically be quite a bit better than the GeForce GT 315 overall. (explain)
Texel RateThe GeForce GTX 560 will be much (approximately 354%) faster with regards to texture filtering than the GeForce GT 315. (explain)
Pixel RateThe GeForce GTX 560 is a lot (more or less 418%) faster with regards to AA than the GeForce GT 315, and also will be capable of handling higher screen resolutions more effectively. (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 (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 can be applied per second. This figure 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 applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
