A Question

Compare any two graphics cards:
VS

GeForce GT 315 vs GeForce GTX 560

Intro

The GeForce GT 315 comes with 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 TAUs and 8 ROPs.

Compare all that to the GeForce GTX 560, which features clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator 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

Theoretically speaking, the GeForce GTX 560 should be 407% faster than the GeForce GT 315 overall, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 560 is quite a bit (about 354%) faster with regards to 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

The GeForce GTX 560 is a lot (more or less 418%) more effective at full screen anti-aliasing than the GeForce GT 315, and also capable of handling higher resolutions more effectively. (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: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 get to the max fill rate.
