GeForce GT 310 vs Geforce GTX 770

Intro

Compare those specs to the Geforce GTX 770, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1046 MHz. The GDDR5 memory runs at a frequency of 1753 MHz on this particular card. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

GeForce GT 310		4712 Mtexels/sec
	Difference: 129176 (2741%)

Pixel Rate

The Geforce GTX 770 is quite a bit (about 1321%) better at FSAA than the GeForce GT 310, and also will be able to handle higher screen resolutions better. (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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over 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 type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
