GeForce GT 315 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which uses a 28 nm design. nVidia has clocked the core frequency at 980 MHz. The GDDR5 RAM runs at a frequency of 1502 MHz on this card. It features 1152 SPUs along with 96 TAUs and 32 ROPs.

GeForce GT 315		25280 MB/sec
	Difference: 166976 (661%)

Texel Rate

The Geforce GTX 760 should be much (about 841%) faster with regards to texture filtering than the GeForce GT 315. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 84080 (841%)

Pixel Rate

The Geforce GTX 760 will be quite a bit (approximately 527%) more effective at full screen anti-aliasing than the GeForce GT 315, and also capable of handling higher resolutions without losing too much performance. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 26360 (527%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher 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 number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
