GeForce GT 315 vs Geforce GTX 760

Intro

Compare those specifications to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this specific card. It features 1152 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 315		52 Watts
Geforce GTX 760		170 Watts
	Difference: 118 Watts (227%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 will be 661% quicker than the GeForce GT 315 overall, because of its higher data rate. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 166976 (661%)

Texel Rate

The Geforce GTX 760 should be quite a bit (about 841%) better at AF than the GeForce GT 315. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 760 is a better choice, by a large margin. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past 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 memory, 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, 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 texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 maximum fill rate.
