GeForce GT 315 vs GeForce GTX 560

Intro

The GeForce GT 315 comes with a clock frequency of 625 MHz and a DDR3 memory speed of 790 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is made up of 48 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare those specifications to the GeForce GTX 560, which has GPU core speed of 810 MHz, and 1024 MB of GDDR5 RAM set to run at 1001 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 315 52 Watts
GeForce GTX 560 150 Watts
Difference: 98 Watts (188%)

Memory Bandwidth

The GeForce GTX 560 should in theory perform quite a bit faster than the GeForce GT 315 in general. (explain)

GeForce GTX 560 128128 MB/sec
GeForce GT 315 25280 MB/sec
Difference: 102848 (407%)

Texel Rate

The GeForce GTX 560 is a lot (more or less 354%) better at texture filtering than the GeForce GT 315. (explain)

GeForce GTX 560 45360 Mtexels/sec
GeForce GT 315 10000 Mtexels/sec
Difference: 35360 (354%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 is a better choice, and very much so. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GT 315 5000 Mpixels/sec
Difference: 20920 (418%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
