GeForce GT 310 vs Geforce GTX 760

Intro

Compare all of that to the Geforce GTX 760, which comes with clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1152 SPUs as well as 96 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
Geforce GTX 760		170 Watts
	Difference: 139 Watts (448%)

Memory Bandwidth

In theory, the Geforce GTX 760 will be 1102% quicker than the GeForce GT 310 overall, because of its higher bandwidth. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 176256 (1102%)

Texel Rate

The Geforce GTX 760 should be much (more or less 1897%) faster with regards to AF than the GeForce GT 310. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 89368 (1897%)

Pixel Rate

The Geforce GTX 760 will be a lot (approximately 1231%) better at full screen anti-aliasing than the GeForce GT 310, and should be capable of handling higher resolutions while still performing well. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 29004 (1231%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
