GeForce GT 310 vs Geforce GTX 770

Intro

Compare all of that to the Geforce GTX 770, which features GPU core speed of 1046 MHz, and 2048 MB of GDDR5 memory running at 1753 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
Geforce GTX 770		230 Watts
	Difference: 199 Watts (642%)

Memory Bandwidth

In theory, the Geforce GTX 770 should be 1302% faster than the GeForce GT 310 in general, due to its higher bandwidth. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 208384 (1302%)

Texel Rate

The Geforce GTX 770 should be quite a bit (about 2741%) better at anisotropic filtering than the GeForce GT 310. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 129176 (2741%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 770 is a better choice, by far. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 31116 (1321%)

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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
